Guppy

Gupeshek can be kept in the general aquarium (but not with fast-floating species that can tear off their fins) with a length of 60 cm, in places with dense thickets of plants, including small-leaved, reaching the surface of the water (among them desirable Indian limnophila and glossy grass), floating plants with roots hanging down, as well as riccia, where the fry will find shelter. To the volume of the aquarium guppies are undemanding.

Gourami
Another large family is the labyrinth fish. The beauty and popularity of these fish is their diversity and beauty. And also in the fact that they are not demanding aeration of the aquarium and can go without it for a long time. This is due to the fact that the homeland - the habitat of the gourami is the rice fields of Asia, where there is little oxygen in the water, and the water itself is still standing.

Goldfish
Here we are with you and got to these posh representatives of the aquarium world. Perhaps, these fish are not only known, but also seen by everyone.

Unpretentious aquarium fish

Caring for aquarium fish - the whole science. At first glance, it is impossible to remember all the conditions and requirements for the content, it is difficult to find the means to purchase a huge aquarium and expensive equipment for it and time to prepare special feeds and regularly test the water. But there are fish that will forgive the newcomer for his inexperience and possible mistakes, and caring for them will not require huge material and temporary resources from him. About these simple to care, tenacious and unpretentious inhabitants of the aquarium and will be discussed.

Viviparous fish

They are considered the most undemanding to the conditions of detention and, in the general opinion, are the best option among aquarium fish for beginners. In turn, among this group there are also champions in vitality. Of course, this is a guppy. These fish are familiar to all, they were popular even in those prehistoric times when the filter, compressor and thermostat in the aquarium were considered a luxury. And the guppies in these aquariums lived, sparkled with their magnificent tails and multiplied.

Small fishes of this species can live in a small amount of water, without filtration and aeration, at different temperatures, exclusively on dry food. Of course, such a life cannot be called a comfortable life, and this may soon manifest itself in a deterioration in the appetite of small fishes and the blanching of their colors. Therefore, it is still very desirable to install a filter in the aquarium, carry out water changes regularly (once a week at 20-30%), and try to diversify the food as much as possible.

Another condition for a long and happy life of gops is that there must be a few of them in the aquarium, not less than 5-6 pieces, since they are packaged and feel alone and uncomfortable.

Relatives of guppies, equally popular in novice aquariums, are swordtails. These small bright fish also do not require special care. They are larger than guppies, so they need at least 40-50 liters of an aquarium; about 6 liters of water should be consumed per individual.Otherwise, the fish is also unpretentious, tolerates non-ideal conditions in the aquarium, organic water pollution or high nitrate content in it, and even breeds under these conditions.

Petilles and mollies are also viviparous fishes, almost as good as guppies and swordtails in their resilience. They need a more constant water temperature. Here, perhaps, all the difference.

The colors and forms of viviparous fish are so bright and diverse that you can create a beautiful, lively and interesting aquarium, using only representatives of these species. And the ease of their reproduction at home (fry are born already well-formed, they eat adult food themselves, and for their successful development it is necessary to ensure only the presence of thickets of small-leaved plants, you can even artificial, where they can hide) and allows even the beginner Aquarist feel like a true fish farmer.

It should be noted that at present breeders have deduced a large number of different forms of viviparous fish - with unusual colors, veil fins, and so on. These fish are unusually beautiful, but they are much more demanding of conditions of detention and not always suitable for inexperienced owners.

Carp

Carp representatives are the next most popular among beginners and ability to survive in difficult conditions.

In this group, in the first place, it should be noted danio rerio. This fish, it seems, takes nothing. In my aquarium, my friends once broke the thermostat, in the very heated water all the fish died and only the danios continued to swim as if nothing had happened. These persistent kids even launched into space.

Danio have quite ordinary appearance, but they captivate with their activity and swiftness. The schooling fish, but does not require a lot of space, 8-10 individuals will be perfectly able to live in a twenty-liter aquarium.

It is also quite easy to propagate them - it is enough to set a female (2) and three males ready for spawning into a small container, put them near the window early in the morning so that the first rays of the morning sun hit the bank and the fish begin to actively spawn. Growing fry, of course, more difficult than that of viviparous fish, but with due diligence and it is quite possible.

Another frequent inhabitant of small aquariums is the cardinal. This is a small-sized, up to 4--5 cm long, slender and mobile fish with bright fins. Cardinals are undemanding to the parameters of water, have a peaceful and livable nature, use dry or live food. A flock of nondescript at first glance cardinals will liven up any aquarium.

Barbus are also representatives of carp. In aquariums there are many species of this genus, the most unpretentious of them is considered to be a Sumatran barbus.

He has a bright golden-black striped color, and indeed in the aquarium it is difficult not to notice, his character is too active. Because of this, the bar should not be settled in an aquarium with calm phlegmatic fish, they will be uncomfortable with this jumping bully. Barbs are prone to obesity, so you should not overfeed them. Another possible problem in fish of this species is the stagnation of calf in females. To avoid this, you need to raise the temperature in the aquarium twice a year, stimulating spawning.


Labyrinth

Labyrinth fish, perhaps the largest and most elegant of those who can advise a novice for a small aquarium. Macropods reach a length of 9 cm, males - 6 cm (plus luxurious fins of almost the same length), and at the same time they can live in a three-liter jar without aeration, if only there is space between the surface of the water and the lid.

These fish have a special organ - a labyrinth, which allows them to breathe atmospheric air, so they feel good in oxygen-poor water, and other water parameters (temperature, hardness, pollution degree) are not too demanding either.

They have a very good regeneration ability, they can quickly restore damaged fins. Their disadvantage is an aggressive, fighting character: the males are completely intolerant of the males of their own species, and in some cases they can attack other species of fish, especially the macropods. Other labyrinth fish - liliusi, gourami - have a more peaceful disposition (although sometimes gourami, guarding the nest, can survive from a small aquarium of their neighbors), but are somewhat inferior to macropods and cockerels by simplicity. They, especially breeding forms, require a constant temperature in the aquarium, clean water, the presence of thickets of living plants.

Haracin

These include such popular species as ternets, neons, various tetras: copper, firefly, rhodostomus. Small, very charming schooling fish with interesting colors, red and golden spots, glowing neon stripes. In ternation, the color is not bright, but its albino form was learned to dye artificially, receiving multi-colored fishes, called caramels.

The mentioned representatives of the haratsin ones are capable of living in small aquariums, however they are more demanding in terms of conditions. In particular, they prefer soft, acidic water and do not like massive changes, so the water for the aquarium is better to peat and change regularly, but little by little. In addition, in the aquarium with these fish is very desirable to have live plants.

Somics

Because of their funny appearance and behavior are very popular with beginners. However, they often lose sight of the fact that rather large catfish grow from the majority of cute little mustaches sold in pet stores. Torakatumov, plexostomus, pterigoplihtov and antsistrusov in an aquarium with a volume of 30-40 liters to keep absolutely impossible.

An unpretentious pygmy corridor (Corydoras pygmaeus) or its close relative dwarf corridor (Corydoras hastatus, catfish) is well suited for small aquariums. They grow only about 3-4 cm, they feel good in a large range of hardness and acidity, do not pay attention to the intensity of light, feed on any dry and live food, if only he was small enough and placed in their mouths. Demanding on temperature only. It should be in the range of 24-26 ° C. Schooling fish, you must keep them in groups of at least 5-6 pieces.

Another small catfish - ototsinklyus. He also does not need large amounts of water for life, but for him the presence of living plants, vegetable dressing and pure water with a low content of nitrates are necessary.

All these catfish are peaceful and can get along with any fish that will not offend them.

Cichlids

If a novice aquarist is immediately serious and ready to spend time on caring for an aquarium and studying special literature, you can recommend him to buy the most simple cichlids - the angelfish and black-striped chichlases. These species need a sufficiently large amount of water (at least 100 liters per pair) and careful selection of neighbors, but otherwise they are not too demanding.

In conclusion, it is worth noting that there are no aquariums and fish that do not require care at all. Fish, like frogs, turtles, tritons are living creatures, and care about them should be constant. If you don’t want to mess with the aquarium, and you just want beauty and pleasant murmur, it’s better not to torture animals and not to suffer yourself, but to buy a bubble panel and admire its pacifying gurgle.

In addition, it is not enough just to choose unpretentious fish, it is necessary to consider the following:

  • fish must be compatible, since if, for example, simple guppies and barbs are placed in one aquarium, nothing good will come of it;
  • it is preferable to place in one aquarium related species or species that live in nature under similar conditions;
  • when choosing fish, it is necessary to take into account what maximum size they can achieve, and based on this, determine the capacity of their aquarium;
  • most small fish are schooling, they need to be acquired immediately by the group.

Only by observing these conditions, you can make your first aquarium a source of beauty and pleasure.

The story of the small and unpretentious fish look at the video:

What kind of fish to settle 10 liter aquarium?

A small aquarium is a tank with parameters of 20x40 cm and less (a nano aquarium) in which small ornamental fish can be placed. The volume of such containers can be from 10 to 20 cubic liters, so they are suitable for the installation of decorations and equipment. In a small aquarium you need to put lighting, plant plants, decor, do not forget about the filter and compressor. That is, a small aquarium should not differ in functionality from a spacious one.


How to set the balance in the mini tank?

Care of a small aquarium, on the one hand, easy, and on the other, takes the hassle. Choose a mini tank rectangular, with straight and smooth walls. It is convenient to clean them with a scraper, to maintain. If the tank is round, then it will be inconvenient to reach its corners, it is difficult to wash. A 10-liter aquarium pollutes faster than a 50-100-liter aquarium. Water changes will have to be done more often, as well as comprehensive cleaning, which is not useful for the biobalance of the aquatic environment and the health of the fish.

The main disadvantage of mini tanks is a small amount of water. It does not fit a lot of fish. There you can settle 1-2 fish, and no more. In a large aquarium, water changes are not strongly felt, in a small one this is a great stress. Any changes in the biological balance: fish death, overfeeding, pollution immediately affect the aquatic environment. The only thing that can be done is to adjust the water parameters in time, feed the fish gently, clean the bottom.

See how the ground siphon in the nano aquarium.

To care for a small aquarium should be the same as for a large one. Once a week you need to change 10-15% of water, if necessary. So that the fish do not have stress, do not replace the water completely, try to add it in small portions. The ideal aquarium filter for such a tank is a pump with an internal sponge. The sponge cannot be washed out under running water, otherwise all beneficial bacteria participating in the nitrogen cycle will die.

If you choose the smallest reservoir, then it will be almost impossible to install plants and decorations. Some skillfully planted even in 3-liter jars of dwarf plants, but it is inconvenient to take care of them. In the 10 liter tank there is the possibility to hold a dwarf anubias, a dwarf arrowhead, an echinodorus "dwarf amazon", a dwarf cryptocoryne. Plants for a small aquarium are able to control the level of nitrite, nitrate and ammonia, create shelters for fish. Make sure that the aquarium was the ground. Choose a substrate treated, clean, without paint. Remember that using a regular scraper to clean aquariums of minimal size is very difficult from the layer of plaque.


Now about feeding. As you know, overfeeding harms not only the health of the fish, but also adversely affects the quality of water. All uneaten decays, turning into harmful impurities and bacteria. Decay products are deposited on the bottom and reservoir machines, disturbing the stability of the biological environment. Fish should be fed, hunger is also not an option. Once a week, arrange fasting days for fish. Add food to 4-6 grains, which pet is swallowed by force. What is not eaten, you need to remove the gauze net.

Let's for fish that live in a small 10-20-liter nursery as much feed as they eat in 2-6 minutes. Flakes, live food, sinking granules fit. They sink slowly and do not pollute the environment. If you live on bottom catfish, they will eat everything on their own. Fish can be fed to their usual high-grade food, without disturbing the diet. It is important to clean everything in time.

See how to make a small aquarium.

Which fish is suitable for settling in a mini aquarium?

What kind of fish can be kept in mini aquariums? In a small 10-20 liter tank you need to settle pets with miniature body size. Fish 2-6 centimeters in length will carry such a volume of water. But remember that even small fish want to swim in a spacious environment. They can not be kept in containers that will restrict movement. Territorial and aggressive fish cannot be accommodated in mini aquariums. Which do not need to settle in a 10-liter aquariums? These are swordtails, barbus averages, cichlids, gourami, danios. They have an active and energetic disposition, they need more space for shelter.


In the aquarium of 10-20 liters, you can settle small barbs, pseudomogil gertrudy, rice fish, cherry barbus, rasbor, erythrosalonus, neon, tetra Amanda. Also there you can keep such fish and shrimp: catfish ottsinklyus, corridor, shrimp amano, cherry shrimp, copper tetra. A representative of the genus Pecilia, viviparous fishes get along well in mini tanks.

You need to buy breeds of fish with a strong immunity, that is, not actually thoroughbred, but hybrids. If you do not have the opportunity to buy a spacious "house" for your small pet, you need to buy a small aquarium with a capacity of 10 liters. There are also often settled well-known Siamese cockerels. The cockerel can live alone, does not get along with relatives, this is after all a fighting fish.

ABC care for aquarium fish

All aquarists, both beginners and experienced, it is important to know how to care for aquarium fish correctly. In fact, their care begins with the purchase of an aquarium, because of its shape, size, material depends on how comfortable the life of pets will be. Aquascape, feeding, compatibility with other aquatic organisms are also important conditions for the harmonious life of the fish. To ensure proper care of the fish at home, you need to familiarize yourself with some rules.

Aquarium arrangement

To choose the right aquarium for fish, consider the following recommendations:

  1. In a spacious tank, fish care will be easier. The products of their vital activity in a close aquarium quickly decompose, poisoning the water. In a spacious tank more water that will be mixed. Cleaning can be done less frequently.
  2. The size of the tank depends on the type of fish and their size. Before buying an aquarium, you should know which pets will be settled there. Large and gregarious fish require a large amount of swimming space. At 5-centimeter fish need 10 liters of water.
  3. Attention should be paid to aquascape. This shelter in the form of caves, moles, clay pots, pipes, rocks, snags and plants. Fish with bulging eyes do not need a lot of scenery due to the threat of injury.

  4. The shape of the tank should be rectangular. This aquarium is easier to clean at home.
  5. Ground, plants, snags, rocks and stones must be selected correctly. They can provide the similarity of a natural biotope, but the main condition is its use. Stone sculptures, soil should not be toxic, or change the parameters of the aquatic environment (acidity, hardness). In addition, everything that will be placed in the tank must be treated with boiling water, special solutions. It is desirable to boil the soil, or chop in a furnace at a temperature of 200-300 ° C. Plants should be thoroughly rinsed under running water. The compact arrangement of the decorations in the aquarium will facilitate the care of them.
  6. Lay the soil in several layers, plant it in it. Place the snags, rocks. Install a water heating system, filter, compressor, water thermometer, lighting. Be careful when working with the equipment. The light should not heat the water too much so that the plants are not damaged and the fish do not become worse. To visually recreate the underwater world, a decorative film can be glued to the back wall of the aquarium.

Fish selection

Instructions for choosing aquarium fish:

  1. Choose pets according to your experience in the aquarium business. Of course, for beginners it is better to choose small and unpretentious in keeping fish, for which care is simple. Learn in advance about the lifestyle of the species, its taste habits.
  2. Find out at what parameters the water can contain a fish, what feed it should be fed and how many times a day.
  3. Choose your aquarium neighbors correctly. It is impossible to settle predatory and herbivorous fish together, especially large and small species. The disproportion becomes the cause of eating some fish by others.

    Watch the video with the rules of compatibility of aquarium fish.

  4. There are schooling fish species, these are small hydrobionts that feel comfortable in the company of their relatives. A large school of non-aggressive fish does not show aggression towards neighbors.
  5. Some fish are suitable only for aquarists with experience. It is important that pet care does not bore you, because they take time.
  6. When buying fish, pay attention to their appearance and behavior. They should not be faded, disheveled scales, fins should be in place. The selected fish must actively swim, not be constantly at the bottom. Choose young fish if you want to breed them in the future. Check with the seller about the feeding regime.

Proper feeding

Constant, varied feeding also makes up the right care for aquatic pets. It is advisable to give food 2 times a day, at the same time. Some species may eventually take food from the hands, but the hands must be clean, without blood and odors. Fish can see or hear a knock on the glass, swim out of shelters in anticipation of feeding. Питомцы могут настолько привыкнуть к режиму, что начнут готовиться к трапезе в одно и то же время. Рыб перекармливать нельзя, это чревато проблемами со здоровьем. Небольших порций, которые они съедят за 3-5 минут, будет достаточно.

Инструкция по кормлению:

  1. Рацион - разнообразный. Травоядные рыбы нуждаются в постоянном получении растительных кормов с клетчаткой, всеядные и хищные рыбы - в мясной пище, насыщенной белками. It is advisable to combine all types of feed: live, frozen, dry, artificial. Live food is best frozen, so as not to infect the water infection. This applies to bloodworms, tubers, daphnia, corets and other feed. Some fish love so-called "cocktails" that can be prepared in the kitchen. Frozen seafood, vegetables pass through a meat grinder, are formed in the form of circles, and put in the freezer.

  2. Overeating shortens the life of fish, or provokes bloating. Once a week you should arrange a fasting day for your pets and not feed them at all. You can feed at 12 noon and 6 pm, or at another time during the day. At night, it is better not to feed. Pay attention to the behavior - if they do not eat, then portions can be reduced, or feed once a day.

Fish Care Basics

Care for water pets should be constant and quality. Cleanliness is a guarantee of health and carefree life, both for the owner and for the pet. Instructions for the care of an aquarium with fish:

  1. Regularly make water changes to fresh and clean. It is easy to get such water - dial the required amount from under the tap into the glass container, leave for 2-4 days, bring to the required parameters (check with indicators). Then pour into the tank. In an aquarium of 200 liters, you need to replace 20% of the water; in a 100-liter one, you can replace 30% of the water. The procedure should be repeated once a week.
  2. Constantly siphon the bottom of the reservoir funnel, removing the remnants of uneaten food. Do not turn off the compressor with aeration, filter, heating without special need.

  3. Every day, watch the pets - their appearance, behavior. If you notice a change - prepare a quarantine tank. Perhaps the fish is sick, and she needs special care.
  4. You should have a scraper for aquarium glass, which perfectly cleans hard surfaces from algal fouling. Stone rocks and snags can be cleaned with a brush. If the surfaces are not cleaned in a timely manner, the biological balance will be disturbed, which will affect the well-being of the fish.

Aquarium fish telescope - the sister of a goldfish

Fish telescope is a type of goldfish. Another name for them is water dragons. A distinctive feature of these fish is their eyes, which are quite large in size, located on the sides. Due to its size and location, the eyes appear bulging. It is because of them that this fish received such an unusual name. Despite the large size of the eyes, the vision of such fish is very poor, and the eyes themselves are often damaged by surrounding objects. Here is a photo of a fish on which it is clearly visible.

The history of the fish

In nature, the fish telescope is not found. Because it belongs to goldfish, and they were bred from a wild crucian. The crucian lives in a lake, a pond, a river, it lives in many bodies of water, and therefore is considered quite common. The basis of its diet are fry, insects, plants.

Initially, goldfish appeared in China, then in Japan, Europe, and only then in America. Based on this, one can guess that China is the birthplace of the telescope.

In Russia, these fish appeared in 1872. Today they are very common.

What does this fish look like?

Although the telescope belongs to goldfish, his body is not at all elongated, but rounded or ovoid. This fish is very similar to the veiltail. Only the latter has no such eyes. Telescopes are owners of a large head, on both sides of which there are large eyes, besides this, the fish has rather large fins.

Today you can meet a telescope of different colors and shapes. Their fins can be long or short. Colors are also quite diverse. The most popular is considered a black telescope. Such fish can be purchased in the store or on the market. However, sometimes they change color, this should be known to the buyer or owner of this fish.

These fish live for about 10 years. If they live in freedom, they can live to 20. Their size varies, and depends on living conditions, as well as on the species. The average size of 10-15 centimeters, sometimes larger, up to 20. But the fish looks like a telescope in the photo.

Content Features

Low temperatures are not terrible for this fish, they can feel very good even in such situations. Despite the fact that these fish are not picky and do not require any special care, novice aquarists should not get them. This is due to their eyes, because they do not see well, they can not notice the food and starve. Another common problem of telescopes is eye inflammation, because after injuring the mucous membrane, they infect the eye.

In the aquarium, these fish live quite well, but they can survive in the pond. After all, the main thing is the purity of the water, the presence of food and friendly neighbors. The aggressive inhabitants of a pond or aquarium can leave sluggish telescopes hungry, which will inevitably lead them to death.

If you intend to keep them in the aquarium, then you should not get a round version. This is because in such aquariums the sight of the fish deteriorates, and in telescopes it is already very bad. In addition, the fish in the round aquarium can stop growing, this should also be remembered.

Nutrition

Feed telescopes can be:

  1. Live view feed.
  2. Ice cream view.
  3. Artificial view.

It is better, of course, if the basis of nutrition is artificial feed. It is represented mainly by granules. And in addition to the pellets, you can feed with bloodworms, daphnia, artemia, etc. The owners of these fish should take into account the vision of their pets, since in order for this fish to eat and find food, it takes much longer than other inhabitants of the aquarium. I would also like to say that the artificial food slowly disintegrates and does not dig into the ground, so it is he who is given the first place.

Life in an aquarium

For the maintenance of this fish is perfect to purchase a spacious aquarium. However, it must be equipped in a certain way:

  1. Telescopes produce a lot of waste, so the aquarium should contain a powerful filter, it is better if it is external and powerful enough. A daily water change of at least 20% is required.
  2. As already mentioned, round aquariums will not work, rectangular will be more convenient and more practical. As for the volume, it will be optimal to 40-50 liters for one fish. From this we can conclude that if the fish are 2, then water will need 80-100 liters.
  3. As for the soil, it should be either smaller or larger. These fish love to rummage in it, sometimes they can swallow it.
  4. Can be placed in the aquarium plants or decor. But do not forget about the problem eyes of these fish. Before you decorate and diversify your aquarium, you need to make sure that the fish will not get hurt.
  5. The water temperature is optimal from 20 to 23 degrees.

The ability of telescope fish to live with other inhabitants of the aquarium

These fish love society. But it is better if this society is like itself. Other species of fish can injure the fins or eyes of telescopes, due to the fact that the latter are slow and practically blind. You can, of course, put to telescopes:

  1. Voilehvost;
  2. Goldfish;
  3. Shubunkin.

But tertseni, Sumatran barb, tetragonopterus as neighbors do not fit the obsalyutno.

Sex differences and reproduction

Until spawning begins, the girl or the boy does not recognize it. Only during spawning in the female the shape of the body changes, because of the calf contained in it, it becomes round. The male differs only in white bumps on the head.

For healthy offspring, individuals of 3 years are most suitable. Reproduction occurs at the end of spring. In order for the parents themselves do not eat caviar, they must be seated in different aquariums. After spawning has occurred, the female needs to be transferred to the main aquarium.

After 5 days, the larvae will appear from the roe, which do not need to be fed. Feed will need to appear later fry. Fry grow in different ways, so the smaller ones should be planted separately, so that they do not starve, since larger relatives will not allow them to eat fully.

Knowing all the information, to grow and maintain telescope fish is not difficult. But you need to take responsibility for these pets only if you can provide them with optimal and, most importantly, safe living conditions.

All about aquarium goldfish


ALL ALL ALL ABOUT GOLDEN FISHES

Dear reader! This article is a team of all the articles on our site. We also tried to supplement the article with the nuances of maintaining and caring for goldfish in an aquarium.
Why do you need such an article? Everything is very simple. Many beginners in the aquarium world do not know how to contain them, make gross mistakes, as a result of which in a month the goldfish at best fall ill with fin rot and at worst pop up with the belly up.

For example, often on our forum, and on the Internet as a whole, they ask the question - why does my goldfish swim sideways or belly up? When you begin to understand, look for the cause of such a disease and ask questions to the owner ... the answer is by itself and literally lies on the surface of the water.
Many do not know, forget, or do not want to know that feeding fish should be balanced, that is, in their diet should include dry food, and live and vegetable. Goldfish are gluttonous, prone to overeating, so the question of balance in the diet for them as for anyone is relevant. As for the aforementioned question, the answer is simple - in the process of eating dry food, goldfish swallow air with food. If you feed them only dry food, fish, due to excess air in the food system, begin to float belly up. The problem is solved elementary - the fish are transferred to the correct, full-fledged feeding and after 3-4 days the goldfish begin to swim normally.
Alas, such examples are mass and it is impossible to highlight everything. But, we still try to do it, by centralizing all the information about goldfish. We will try to focus on the most important points of the content of gold aquarium fish.

Goldfish: description, types, highlights


The variety of aquarium fish sometimes affects. And given the fact that one species of fish has its own varieties - the aquarium world becomes just gigantic.
Sometimes it is even difficult for an experienced aquarist to tell what kind of fish it is. Hopefully, the following selection of GOLDEN FISH SPECIES will help you figure out who is swimming in your tank.
Carassius auratus
Order, family: crucians.
Comfortable water temperature: 18-23 ° C.
Ph: 5-20.
Aggressiveness: 5% are not aggressive, but they can bite each other.
Compatibility: with all peaceful and non-aggressive fish.
Golden, or Chinese, crucian carp in nature lives in Korea, China and Japan.
The goldfish was bred in China more than 1,500 years ago, where it was bred in ponds and garden ponds on the estates of nobles and wealthy people. For the first time, a goldfish was imported to Russia in the middle of the 18th century. Currently, there are many varieties of goldfish.
The color of the body and fins is red-golden, the back is darker than the abdomen. Other types of color: pale pink, red, white, black, black and blue, yellow, dark bronze, fiery red. A goldfish has an elongated body, slightly compressed from the sides. Males can be distinguished from females only during the spawning period, when the female's belly is rounded, and the males on the pectoral fins and gills develop a white “rash”.
For the maintenance of goldfish best aquarium capacity not less than 50 liters per individual. Short-bodied goldfish (voiletails, telescopes) require more water than long-bodied (simple goldfish, comet, shubunkin), with the same body length.
With an increase in the volume of the aquarium, the density of landing can be slightly increased. In particular, in the volume of 100 l, you can settle two goldfish (it is possible and three, but in this case it will be necessary to organize a powerful filtering and make frequent water changes). 3-4 individuals can be planted in 150 l, 5-6 in 200 l, 6-8 in 250 l, etc. This recommendation is relevant if we are talking about fish of at least 5-7 cm in size without taking into account the length of the tail fin.
A special feature of the goldfish is that it loves to rummage in the ground. As the soil is better to use coarse sand or pebbles, which are not so easily scattered fish. The aquarium itself should be spacious and species, with large-leaved plants. Therefore, in an aquarium with goldfish, it is better to plant plants with hard leaves and a good root system.
In the general aquarium, goldfish can be kept along with calm fish. The necessary conditions for the aquarium are natural light, filtration and aeration.
Water characteristics: temperature can vary from 18 to 30 ° C. The optimum should be considered in the spring-summer period 18 - 23 ° С, in the winter - 15 - 18 ° С. The fish tolerate a salinity of 12-15%. If you feel unwell fish in the water, you can add salt, 5-7 g / l. It is advisable to regularly replace part of the volume of water.
Goldfish in relation to food unpretentious. They eat quite a lot and willingly, so remember that it is better to underfeed the fish than to overfeed them. The amount of daily food should not exceed 3% of fish weight. Adult fish are fed twice a day - early in the morning and in the evening. Feed is given as much as they can eat in 3-10 minutes, and the remnants of uneaten food should be removed. It is necessary to include both live, and vegetable food in their diet. Adult fish that receive proper nutrition can endure a week-long hunger strike without harm. It must be remembered that when fed with dry food, they should be given in small portions several times a day, because when they get into a wet environment, in the fish's esophagus, it swells up, increases significantly in size and can cause constipation and disruption of the normal functioning of the digestive organs of the fish, the consequence of which may be the death of the fish. To do this, you can first hold the dry food for some time (10 seconds - flakes, 20-30 seconds - granules) in water and only then give them to the fish. When using specialized feeds you can improve the color of the fish (yellow, orange and red).
Long-bodied goldfish are durable, with good conditions of maintenance can live up to 30 - 35 years, short-term - up to 15 years.

COMPATIBILITY OF GOLDEN FISHES WITH OTHER FISH SPECIES The issue of compatibility of Goldfish (Carassius), on the one hand, is quite simple, but on the other hand, it is complicated and this is due to a number of specific nuances that are characteristic of this particular family of aquarium fish.
I think this topic should be started with the fact that ALL BREEDS OF GOLDEN FISHES were obtained as a result of a thousand-year selection. Therefore, Vualekhvosti, Orande, Telescopes, Shubunkin and others - these are artificially bred breeds, which, in fact, were obtained from one ancestor - the Chinese silver carp.
Therefore, if we talk about the intraspecific compatibility of Goldfish, that is, the possibility of sharing, for example, telescopes and koi carps in an aquarium or a pond, then this coexistence takes place - all types of Goldfish are absolutely compatible with each other. But, HERE THERE ARE ONE BUT! Since all the Scrofula are from the same tribe, they are in the same reservoir, they will interbreed with each other, resulting in "bastards" or if you want mutants - outbred hybrids. Taking into account the experiments, such a joint residence leads to degeneration and the transformation of the fish back into a crucian. Therefore, if you plan to get offspring and breed Goldfish, then their species content in the general reservoir is FORBIDDEN! Before the discussion, the specific compatibility of Goldfish with other fish. It should be noted that Goldfish are large, slow, slow-moving fish. And this specifics should definitely be fat. For example, if you keep the Veiltails in a small aquarium with others, whether they are the most peaceful fish, all the same, over time, the fish will die, since the lack of free space - standards of maintenance, will do its job and the fish will simply “gnaw”.
In addition, when discussing the compatibility of any species of fish, it should be borne in mind that a single fish taken has its own character. In this connection, even following all the rules of compatibility of aquarium fish, a negative result can be obtained at the output. In order to maximize this factor, it is always recommended to plant different fish with young and at the same time, rather than gradually add new ones to old ones. Now let's look at the compatibility of Goldfish with specific species of other fish.
Goldfish and Cichlids: Astronotus, Angelfish, Discus, Akara, Apistogramma, Parrots, Tsikhlozy: a diamond, black-striped, Severum and other cichlids.
Such a union, alas, is not possible. All the fish of the cichlid family are aggressive and will not give life to the golden fish. Astronotus generally perceives Gold as a good live snack.
Therefore, to keep them together is strictly contraindicated, even with small cilida.
Somehow, I tried to combine veil eyelids with Goldfish, but alas, they had to be planted in the future. Despite the fact that the veil scalars are slow and somewhat similar to gold, all the same, after a couple of days, races began throughout the aquarium.
So, I recommend not experimenting - this is wasted time and money!
Goldfish and Tetras: neons, minors, ternsim, pulcher, lanterns, glass tetras, congos and other characteristic fish.
Here the situation is fundamentally opposite. All tetras are so peaceful fish that their union with Goldfish will be a wonderful variety of fish in your aquarium. One, but !!! When Goldfish grow up, they may burst into small tetras, therefore it is better to take “large” Kharacin fishes, for example, ternets or Congo, to Zolotuha.
Goldfish and Labyrinth: all gourami, lyalius, macrapod others
I do not even know what to say to you. On the one hand, they are compatible, but on the other hand they are not. This is due to the fact that the labyrinth, in particular gourami, very unpredictable fish and each individual gourami has its own character.
So that it is clear, I will give an example from my experience. Once upon a time, when I started my first aquarium of 35 liters and stuffed a bunch of fish there, including two marble gouramies, the latter were like mice, did not touch anyone and coexisted peacefully in the “little hostel”. But when one day I planted another blue gourae into a large aquarium, he made such a riot that it was bad even for small cichlid. I had to take her back to the pet store.
At the same time, lyalius - these are scared fish, I have no experience, but I think that it will be bad for them with Goldfish.
In view of the above, the coexistence of Gold with Labyrinths is a confusion, so this neighborhood is not recommended.
Goldfish and Aquarium Catfish, other bottom fish: corridors (speckled catfish), antsistrusy (catfish sucker), fighting, akantoftalmusy, green catfish brochis, tarakatumy and others.
In general, there is 100% compatibility. I draw your attention, only that not all somas are very peaceful. For example, Botsia Modest or Bai are somiers who can bite. Or, for example, ancistrus at night can easily stick to sleeping Goldfish, from which the latter will look like plucked hens.
Otherwise, everything is OK! Moreover, all aquarium catfish are good helpers in the fight with poop from Goldfish. Provide an aquarium bottom to the catfish and the frequency of the aquarium floor siphon will decrease.
Goldfish and carp: barbs, danios and others.
It should always be remembered that Goldfish are slow and any neighborhood with nimble fish, and even more so those who can pluck them is not desirable. I do not see anything criminal in the joint content of danios and goldfish, but I do not recommend barbs. Sumatrans easily bite Golden.
Goldfish and pezillium, viviparous fishes: guppies, swordtails, mollies and others.
I read somewhere that guppies can attack and bite off Goldfish! But, something I can not believe in these stories. I can’t even imagine how this gopeshka will be able to covet on a big Golden Fish, unless they attack the crowd))).
I admit honestly, I don’t have any experience in keeping live beetles and Goldfish. And in general, it is somehow not solid to keep golden aksakals of the aquarium world and unpretentious live-bearers together.
And I also want to offer you this topic like the compatibility of goldfish and aquarium plants.
Who started up Goldfish knows that this issue is acute, as the Golden family well just loves plant food. To avoid the disgustingly plucked aquarium plants, I give my Golden twice-weekly grown duckweed from another aquarium. It is also possible to recommend to keep Goldfish with aquarium plants that will be too tough for Goldfish: Anubiases, microsoriums, cryptocorynes, as well as mosses.
For more on this, see this article - FISHING EATING PLANTS WHAT TO DO?
Summing up, it should be said that, nevertheless, Goldfish are fish intended for a specific aquarium that require special, special attention. Moreover, the cost of these fish is quite high, they are long-lived compared to other inhabitants of the aquarium and therefore it would be a shame to lose such a fish due to the fact that some five-kopek antsistrus did not let her sleep at night. See also the article. Compatibility of aquarium fish.
What to feed the goldfish? Golden feed. Goldfish - extremely playful, cheerful and voracious creatures. They quickly get used to the person of their breadwinner, and as they approach the aquarium, they jump out of the water like piranhas with hungry eyes. This behavior of your waterfowl pets can be repeated 10 times a day, but this does not mean that the goldfish are hungry all this time. This is just a conditioned reflex. It is necessary to feed your pets 1-2 times a day with one pinch of dry food, cube freezing of live food, etc. This is quite enough for their normal growth and development. If you feed more often, the fish will behave very sluggish, in addition their life expectancy will be reduced.
Despite the fact that the process of feeding goldfish can bring you a lot of pleasure - do not abuse it. In fish, there is no sense of saturation. Do not forget about it. So do not overdo it. And your pets will long please your eyes and soothe raging thoughts.
And now from the lyrics, to the point!
Goldfish need a balanced diet. Their diet should include both live food - bloodworm, artemia, daphnia, rotifers and other food: dry and especially vegetable.
If we talk about proportions, then in my opinion for goldfish, this proportion looks like 40% live, dry and 60% vegetable food.
Live food, adore all the fish and gold is no exception. When keeping Zolotuh in an aquarium, it is better to use frozen live food, as they are safer than full-scale.
Dry feed - a universal remedy for feeding any fish. Manufacturers of aquarium feed took care of the usefulness of the diet. Therefore, if you feed only goldfish with such food, this will be quite enough for their well-being (in the sense of getting the fish all the necessary elements). But if you want to feed your goldfish to be elite))). It is necessary to introduce vegetable feed and only natural.
How is this achieved ?! Yes, very simple. You need to breed Leopard or Riccia, well, very golden people love this aquarium vegetation.
Here, please see how much duckweed grows in my week in an aquarium with scalars. All she goes to feed goldfish. Economical and non-GMO!


As it is known, duckweed and riccia grow very quickly and do not require special conditions for maintenance. For a week you will grow it on a scale sufficient for goldfish to feed. It should be diluted in a separate aquarium and transferred to scrofula 2-a - 3 times a week. That's all you need.
It is necessary to distinguish the feeding of goldfish in the aquarium and in the pond.
For feeding goldfish in a pond, it is recommended to use meat chips mixed with bread, as well as hard boiled cereals: buckwheat, oatmeal, millet, etc. The pond must be with vegetation !!!
If anyone is interested in this question, I recommend you to talk with our user "Muri", she is a noble ruler of goldfish in the pond!
I feed my goldfish with the following formula:
Resurrection - live food, Monday - Wednesday is dry and substitutes, Thursday - duckweed, Friday - Saturday - dry and duckweed. Sometimes I give a day of discharge - I don’t feed at all. On such a feed my scrofulous - fat and fluffy !!! :)

HOW TO DETERMINE THE FLOOR OF THE GOLDEN FISH: THE MALE BABY AND THE CABLE! Everyone wants to know the sex of their goldfish, unless of course the goldfish are not intended solely for decorative purposes. Real goldfish fans usually want to get offspring from them, and here the definition of sex is of particular importance. There are several ways to determine the sex of goldfish.
During the spawning period, males of goldfish are easier to identify than females. Males develop tubercles or white tubercles, growths along the pectoral fins and gill covers. In addition, males form dented teeth, the so-called "saw", on the male front fins. Females become slightly asymmetric, especially in the abdomen. They look bloated.
At the end of the spawning period and after several spawning spawns in some males, the thoracic region becomes rigid. It is rather difficult to determine this state, therefore, those who are not able to do this can be comforted by the realization that not many can distinguish a goldfish female from a male.
Here are a few more ways to determine the sex of a goldfish, but even they are useless if the fish is not even a year old *, that is, if the fish is not sexually mature.
1. Males have an outgrowth extending through the posterior part of the ventral fin to the anus. In females, this growth is either completely absent or much smaller.
2. In females, the area between the ventral and anal fins is soft, and in males it is hard.
3. Although it is difficult to see, but the anus of females is round and convex, while the anus of males is thinner and concave.
4. The male's abdominal fins are pointed, and the female's fins are round and shorter.
5. The color of the females is brighter and they are more active. This method will undoubtedly help distinguish the female.
6. You can run the female goldfish in the aquarium and watch the reaction of the other goldfish. Males will swim to a new fish, and females will not show interest.
* Do not be surprised, if in a pet store when buying goldfish, give your question to the male and the female, you will be told that this is not possible! Sex differences in the family of goldfish appear only with the onset of sexual maturity, i.e. after 1 year.
Reproduction and breeding of goldfish
Goldfish is one of the most ancient aquarium fish. Their story begins with the first century of our Era and Ancient China. Even then, the emperors of the East and Buddhist monks began to maintain, breed and select goldfish.
Actually, therefore, at present there are a great many aquarium goldfish, and their cost can vary from 2 dollars to several thousand US.
So, if you want to feel like a true goldfish breeder, emperor or Buddhist monk, then this article is for you!
Breeding or breeding goldfish, is not a difficult task.
However, goldfish are not guppies and in order to get offspring you still have to work hard and be patient. In addition, you need to have a sufficient number of aquariums or ponds.
You can't get off with one aquarium!
Goldfish breed independently, without any hormonal injections or without creating too specific conditions. Actual, good maintenance and proper feeding is the criterion and incentive for spawning producers. All types of goldfish can spawn in aquariums of a small volume of 30 liters. However, better results can be achieved in larger aquariums or in ponds.
Spawning of goldfish can occur at a temperature of 16 degrees Celsius, but it is better to maintain the temperature of the aquarium water at a level of 22-24 degrees Celsius. After replanting manufacturers increase the temperature by 2 degrees. The water level in the spawning pond should be 20-25 centimeters, the water should often be replaced by fresh and purged.
Unlike many other spawning aquariums, spawning for goldfish should be well consecrated all light day. If it is a pond, then the sunlight should be diffused, and the pond should be equipped with shelters in the form of floating plants.
Producers are planted in a spawning aquarium in the ratio of 1 female to 2-3 males and richly fed with live food (bloodworms, earthworms, daphnia, ground meat with bread, etc.). At the same time they try to select manufacturers based on their size. Especially females - the bigger they are, the more eggs they sweep out. And vice versa - small females toss less eggs. They equip an aquarium with vegetation (such as a combo, riccia, duckweed, a peristist, etc.), and do not carpe the bottom of the aquarium - on a clean bottom the eggs retain and do not die, but some aquarists set up a separate grid. Sexual maturity in fish comes to a year of life. In this case, the males appear on the gills white bumps and the so-called "saw" on the front paired fins, and the females are growing stout with caviar, their body is bent.
A female matured for breeding emits a special substance that has a characteristic odor and is particularly concentrated in the genital organs. Actually, this smell attracts males and is a signal of a female's readiness for reproduction. Under the influence of this secretion males begin to swim for females.
Under pond conditions, it is recommended to perform the above spawning manipulations in March – April, with the expectation that spawning will begin in May – June. It is believed that this is the most prosperous time for the successful ripening of caviar. In addition, at this time it is easier to provide the eggs and fry with the necessary comfort.
If the courtship of the males began earlier than March - April and the spawning should be delayed, the producers are seated and also the water temperature is lowered to the desired period (period).
The peak of reproduction of goldfish is accompanied by violent courtship of the males - they chase the female around the reservoir, and on the day of spawning, these courtships look like a frank pursuit.
Taking into account such features, the spawning aquarium is equipped with soft aquarium plants and not sharp decor (it is better without it at all). Otherwise, the fishes will sweep, and their fins will be torn after spawning.
The spawning begins with the first rays of the sun and lasts 6 hours. Spawning gold can every month until October. During one spawning, the female can sweep up to 3000 eggs. In the "home" spawning of goldfish can sometimes occur continuously - year-round. However, this leads to the exhaustion of manufacturers, and in this case they should be given rest, seated in different aquariums.

The spawning of the eggs takes place gradually - the female driven by the males touches the vegetation or walls of the aquarium and releases 10-30 eggs, which the males immediately fertilize - watering the eggs with milt.
Then, sticky caviar falls to the bottom or sticks to the plants.
Eggs on the first day are slightly orange and slightly flattened, the diameter of eggs is up to 1.5 millimeters. On the third day, the eggs are straightened and discolored, in connection with which they are difficult to detect.
Immediately after spawning, the producers are removed from the spawning tank, otherwise the offspring will be eaten.
The water level in spawning caviar is reduced to 10-15 centimeters and protected from overheating and excessive sunlight (if it is a pond). Aquarium intensively aerated.
The appearance of fry from caviar depends on the water temperature. At a water temperature of 22-24 degrees Celsius - the incubation period is 4-5 days, but at a temperature of 14 degrees Celsius it can reach 7-8 days.
On the second day after the appearance of the young in the aquarium, it is recommended to launch snails (for example, coils) so that they eat the dead and not fertilized eggs. You can carefully assemble yourself, but it is more difficult than it seems. It is very important not to kill the young. At the same time, leaving the dead calf is fraught with - live larvae do not tolerate "dirt" and can get sick.
Young goldfish in the first days is weak and harmless, in fact it looks like a reed with eyes and a yolk vesicle in the middle (the yolk bubble is necessary for obtaining nutrients in the first days of life). Fry move in spurts and can stick to the stop.
After about 2-3 days, they begin to blithely float around the reservoir, and from this point on, the young need to be fed with starter feed: live dust, the finest alga, and other finely ground to feed dust. After 2 weeks, you can give larger feed. At the age of one month, juveniles are capable of taking small bloodworms. As a starter feed, they also use egg yolk finely ground in water, as well as the soaked oatmeal grated in the dust. The fry are fed abundantly, but in portions - little by little but often.
We can recommend the following feed for young goldfish.
JBL GoldPearls mini is premium class granules, packaged in 100 ml.
It has a special recipe ideal for young fish. The diameter of the granulated feed 1-2 mm. Contains spirulina and carotenoids, which contribute to the development of good fish color, contain proteins (10%) from wheat germ, fatty acids.
After two weeks the fry are planted in a 30 liter aquarium at the rate of 250 fry per aquarium. Aquariums flush or replace water frequently. Without purging, it is recommended that 120 fry be planted per aquarium. So they contain up to 2 months of age, gradually sorting by size and reducing their number. Fry are caught not with a net, but with a saucer or other utensils. So they are easier to get and count.
spawning aquarium for goldfish
Sorting carried out on the principle of rejection. Harvested juveniles with defects, juveniles lagging behind in growth, etc. In the end, get pedigree goldfish.
Defective and non-standard young, unfortunately kill. First, because it, as a rule, does not survive itself, and secondly, even if it survives, nothing good comes out of it. With its further content, you risk getting outbred offspring "bastards", but if you go further, then the fish just degenerate into goldfish.
At first, the scaled juveniles of goldfish have a silver-gray color, like the progenitor of the goldfish. Coloring appears only at the age of 3-5 months. To improve the brightness of the fish color, it is recommended that "sunbathing" light should be diffused. In an artificial reservoir, no shading is necessary, on the contrary, the aquarium is intensively illuminated with lamps. It is worth noting that the color of goldfish can vary in fact a lifetime.
Scaleless fry do not pass the aforementioned period of silver color and already at two weeks of age begin to turn into their final color.
Juveniles of goldfish are very capricious and prone to disease. To avoid mortality of offspring, you should regularly monitor the cleanliness of the aquarium, aeration and filtration. Constantly monitor the population - do not forget to settle as they grow.
When breeding goldfish need to strictly observe the species crossing. All goldfish can interbreed with each other (for example, veil tails with comets).
However, this will lead to degeneration and wastelessness of scrofula.
Summing up, you can make a short list of what you need for breeding goldfish:
- one-year-old males: 1 female, 2-3 males.
- aquariums: the main from 150 liters, spawning from 30 liters, aquarium for youngsters; (aquariums should be illuminated).
- aquarium soft-leaved plants;
- of course: aeration, filtration, thermostat;
- feed for fry;
- improvised aquarium equipment;
- suction water;

Why die fish or the sad fate of goldfish!
The motive for writing this article was the communication on the Fanfishka.ru form with a certain citizen who, in the section on helping to determine the disease of the fish, wrote - “Help me, please, I have a telescope at the age of 6 months that I haven’t eaten for three days. , there is enough air. There is no external damage and swelling. Help if you can still, it's a pity to lose the fish. "
Being a conscientious and sensitive person, I gave her a plan of action and events according to the full scheme, advised the preparations. And then, when I wrote everything, I thought - why should I treat it so radically, maybe the reason for the poor health of the fish lies on the surface? :)
In this connection, I asked a citizen: "Tell me, what is your aquarium volume, who lives there besides the telescope, etc."
When I received the answer, I just went nuts! I’m trying to get along with treatment and help, but it turns out that ... read the answer: "Aquarium 80 liters. 1 gourami, 2 thorns, 2 gold, 2 telescopes (1 patient, another healthy, but for some reason does not grow), 2 danios, 2 small antsistrus, 2 speckled catfish, 1 angelfish, 2 ampoules ... ".
The reason that the telescope was bad - was revealed !!!
Imagine if 16 people planted in an eight-meter hut, how much would they stretch? ... Whatever the conditions in this hut, the sea would start a month later.
Vendors of pet shops are selling fish to beginner aquarists, using their insatiable desired “I want this fish, this one and that one and those catfish”. At the same time, neither of them think about the further fate of the fish.
Sad! But for some reason, this is exactly the fate of "cramming nevpihuemoe" comprehends only aquarium inhabitants. Imagine, mother and daughter come to the pet store and say: "Give us 15 cats, 3 Yorkshire terriers, 5 chinchillas and one sheep-dog and 2 more parrots do not forget." Unfortunately, with aquarium fish this is exactly what happens.
And then, after a while, a convulsive scripture begins and the search for an answer to the questions: why the fish die and die, why do the fish lie at the bottom, float or swim on the surface, do not grow and do not eat! HERE'S OWN, THAT I HAVE FORGOTTEN ME TO WRITE THIS ARTICLE! This is some kind of attempt to stop the mockery of fish! An article for future similar questions. An article that will somehow help newcomers and people who are going to buy an aquarium to understand that the fish are the same living things as we do - they grow, require certain conditions of detention, have their own characteristics, etc.
Very clearly, this problem is seen in Goldfish (pearls, comets, telescopes, veils, shubunkin, oranda, ranch, koi carps, etc.). People either do not know or do not understand that this family of fish belongs to large species. In fact, they need to be kept in ponds (as it was in Dr. China) or in large aquariums.
But it was not there! People for some reason have developed a Hollywood stereotype that Goldfish looks beautiful in a round small aquarium.
HOWEVER, THIS IS NOT THE CASE!!! The minimum volume of an aquarium for a pair of goldfish should be from 100 liters. This is the minimum in which they can live normally, and it’s not a fact that they will grow "to their full height."
Therefore, recalling the above example with a citizen, which has an 80-liter aquarium, in which: 4th scrofula, scalar, gourami and others ... it is not surprising to hear "My golden fish does not eat anything, lies at the bottom or swims belly to the top." And it touches the question, why do they not grow?))) But how can you grow here, you wouldn’t die!
In addition, in this example, there is a relative compatibility of fish. We must not forget that Scalaria is a peaceful, but still South American cichlid, and somehow it’s not a friend with goldfish. The same goes for the gourami - they are peaceful, but snooty individuals come across.
Summarizing what has been said, I earnestly ask everyone not to violate the norms and conditions of keeping the fish. Do not be greedy! And then your fish will grow beautiful and big. Somewhere I read that for 1 cm. The body of a fish without a tail should have 2-3 liters of water in an aquarium. Who cares here is a link to the compilation - How much can the fish in an aquarium X liters (at the end of the article, select the desired aquarium volume).
Now I would like to talk about other reasons that lead to poor health of fish, without any visible reason (signs of the disease are not visually visible).
If the norms of the volume of the aquarium are not violated, the compatibility of the fish and their number are not violated, and the fish still float or vice versa lie at the bottom and swallow air, then the reason may be: Poisoning fish with nitrogen, ammonia, and more simply poop. We live in the air, and the fish in the water. Parameters of aquarium water directly affect the health of the fish.
In the process of life, aquarium fish and other inhabitants defecate, another organic matter dies, the remains of food decompose, which leads to excessive saturation of water with nitrogenous compounds that are detrimental to all living things.
Thus, the cause of poor health or a pestilence in fish may be:
- lack of care for the aquarium (cleaning, cleaning, siphon, no filter or replacement of aquarium water).
- overfeeding fish (the presence in the aquarium is not eaten feed).
- untimely disposal of dead fish, etc. (some novices watch snails burst dead fish, this is absolutely impossible).
What to do in this case? It is necessary to eliminate the sources of nitrogen excretion:
- urgently transplant fish into another aquarium with clean water;
- strengthen aeration and filtration;
- clean the aquarium, and then replace 1/2 of the aquarium water with fresh water;
- Pour into the filter aquarium coal and ion exchange resins (zeolite), use another aquarium chemistry (Nitrate Minus Perls, Bakozym, at least Sulfur Nitrivek);
It should always be remembered that aquarium water should be replaced weekly. However, this is not always good - old water is better than fresh, especially for young aquariums, in which the biobalance is not yet tuned. So this should also be done with the mind and as needed. If you see that the water in your "young aquarium" is not green, not muddy, etc. Replace at the beginning of 1 / 5-1 / 10 of the volume of aquarium water, but often 2-3 times a week. However, one should always keep in mind that clear water is not an indicator of its purity. With that said, it is necessary to develop your own “tactics” of water changes based on the volume of the aquarium, its age and fish preferences, etc.
Emergency fish transfer is a temporary measure, if the fish is very profitable. As a rule, when a fish is not feeling well (lying on the bottom, swallowing air, swimming on its side, etc.), such an action brings it to life and after 2-3 hours it is cheerful and cheerful.
It should be remembered that such a transplant should be done in the water at about the same temperature as in the aquarium, the water should be separated (preferably), do not forget to provide aeration. And yet, if there is no other aquarium, an emergency temporary transfer can be carried out in a basin or other vessel.
About coal. Aquarium coal is sold in any pet store. It is not very expensive, so I recommend to buy it in reserve. Coal - this is a great additional measure in the fight against "shit and other evil spirits." If it is not at hand, you can temporarily take human activated carbon, wrap it in gauze or bandage and put it in the filter. You also need to understand that aquarium coal is not effective against nitrites and nitrates to eliminate them using ion-exchange resins and other chemicals. Watch
Water filtration Everything is simple. The aquarium filter must be suitable for the volume of aquarium water. Additional helpers: aquarium plants, as well as snails, shrimps and crustaceans.
In the end, we can advise the drug for quick cleaning of the aquarium from sewage - TetraAqua Biocoryn.
Another reason that the fish die can be the wrong adaptation of newly purchased fish.
Firstly, Do not release new fish immediately to the aquarium. Everyone knows that. Let them acclimatize: Therefore, about the article, see All about the Acquisition of Transplant Transportation of fish!
Secondly, fish that lived in a pet store or grew up in another reservoir are accustomed to certain water parameters (pH, hD, temperature) and if you transplant them into water with radically opposite parameters, this can lead to their death within a day or a week.
Actually therefore for the correct adaptation there are so-called quarantine aquariums. You kill two birds with one stone: check whether new fish are contagious and adapt them to new conditions. The quarantine principle is simple - it is a small aquarium (another reservoir) into which new aquarium inhabitants are launched and within a week they are checked for lice, as well as they gradually add aquarium water from the aquarium in which they will live.
You can do without quarantine, but it is a risk! As a rule, it carries in 80% of cases, but 20% still remain. In order to neutralize these 20%, I recommend to transfer fish with Tetra AquaSafe (Tetra AquaSafe). This preparation "improves" aquarium water and reduces the stress of fish during transplantation.
Third reason the fact that the small fish is bad asphyxia, caused by the lack of sufficient aeration of aquarium water.
The obvious signs of asphyxiation (suffocation) in fish are: frequent opening of the mouth, heavy breathing, wide opening of the mouth - as if yawning, the fish swims near the surface and there is enough oxygen.
You should know that the fish breathe oxygen dissolved in aquarium water, which they pass through the gills with water and if it is not enough of the fish simply suffocate.
Enhanced aeration and bringing it back to normal will correct the situation!
Another fourth reason Ascent of the fish can use tap water to the top.
Opinions on this are different. While talking and discussing this topic, some comrades say: "Yes, all this is fikhgnya, I fill in the unstable tap water in the aquarium and everything is fine - the fish will not die." However, it is worth noting that tap water in many regions of the CIS is simply terrible! It contains so much bleach and other impurities that it is scary to use it. Somewhere, of course, the water is better here and “carries” - the fish do not die. In Austria, for example, tap water is generally spring water from the Alps, but alas, where are the Alps, and where are we ?!
Therefore it is very important to use only separated water for the aquarium. In addition to the fact that chlorine will evaporate from the water and heavy impurities will settle, excess oxygen will also be released, which are no less destructive for fish.
What to do if you poured tap water and fish from this poplohelo? Ideally transplanted into separated water. However, if you originally poured water, then you probably do not have separated water. One way out is to add aquarium chemistry that stabilizes the aquarium water. For example, the above Tetra AquaSafe.
Fifth reason: This is a violation of the temperature regime.
The generally accepted temperature measure of aquarium water for many fish is 25 degrees Celsius. But too cold water or too warm leads to all the same symptoms: the ascent of the fish, lying on the bottom, etc.
With cold water, everything is clear - you need to buy a thermostat and bring the reduced temperature to the desired one. But with too warm water is much more complicated. Usually aquarists encounter this problem in summer, when the water in the aquarium boils and rolls over 30 degrees, from which the fish become lethargic and "faint".
There are three ways out of this situation:
- cool the aquarium water handicraft: using frozen 2n. bottles from the fridge. But - this is not very convenient, because frozen water quickly gives off cold and you need to constantly change the bottle. In addition, jumps and temperature fluctuations - there, no less harmful than just elevated water temperature.
- sold special installation cooling aquarium, but alas, they are expensive.
- buy an air conditioner and install it in a room with an aquarium, in addition to room stuffiness, the air conditioner will knock down the aquarium heat.
The last option in my opinion the most acceptable.
The sixth and seventh reason
Sometimes the cause of bloating the fish and swimming a belly or side to the top is overfeeding. Again, this reason is largely related to goldfish, because they suffer from gluttony, overeating and begging. Do not enter them on occasion. Feed them exactly as much as it should be. Otherwise, your gluttons will earn inflammation of the gastrointestinal tract or, more simply, they will suffer from constipation!
Another reason for which the fish can lie down for no apparent reason is stress. Well, do not like her neighbors and that's it. Or it often happens that they take young fish, and all the boys and one female grow out of it, and as a result, the boys start a showdown - who is in charge. The weak begin to chase and tyrannize, with the result that they are hammered into a corner, lie on the bottom, well, and die. There is only one way out, to resettle everyone, give them to friends or back to the pet shop.
What else can affect the health of fish:
- Excessive lighting or stress from it;
- decorating the aquarium with chemically dangerous decorations (metal, rubber, plastic);
- overdose of drugs;
Summing up, it is possible to make an unequivocal conclusion that the correct maintenance of fish is a panacea for many aquarium ills. If you are attentive to your aquarium dwellers, they will thank you too.
beauty and longevity!

Why die fish in an aquarium?

It is very unpleasant when the fish begin to die in the aquarium. It would seem that everything was done correctly: clean water was poured, aquarium equipment was working, the fish received timely feed. Despite this, the animals die. Unfortunately, this situation occurs in newcomers of the aquarium business quite often, which is why it is necessary to arm yourself with knowledge of the causes of this phenomenon. Each novice aquarist should understand the following in advance: if conditions are created in the water house for its inhabitants that are as close as possible to their natural habitat, then they will not get sick, much less die.

At the very least, the risk of death will be minimized.

Practice shows that in the overwhelming majority of cases, the death of fish is caused not by any external diseases, but by errors in content, illiteracy and carelessness of their owners. There are various reasons for this unfortunate phenomenon or a whole combination of causes and factors that should be considered in detail.

Poor quality aquarium water

This does not mean that the water is very dirty or muddy. No, it can be relatively pure, but poisoned by toxic chemical compounds, which are formed as a result of the vital activity of fish.

Harmful Chemistry

We are talking about nitrogen compounds, which include ammonia, ammonium, and other nitrates. These toxins will inevitably be present in the aquarium, as the fish every day leaves a lot of waste, which is constantly decomposed.

Thus, the visual purity of water is often accompanied by the appearance of an unpleasant smell of rot, which indicates a high concentration of toxic nitrogen compounds.

This smell is especially clearly felt if the aquarium is overcrowded and the system of biological water purification does not cope with the processing of toxins. As a result, the fish begins to gradually get poisoned and subsequently dies.

This state of aquarium water is formed in the following cases:

  • in the new aquarium has not yet reached the ecological balance;
  • beneficial bacteria that process toxic nitrites into neutral nitrates are not yet at full capacity;
  • new fish have been added to a working balanced aqua system;
  • overpopulation of the aquarium;
  • biofilter failure;
  • improper maintenance and cleaning of the biofilter, resulting in the destruction of the colony of beneficial microorganisms.

On this basis, certain measures are taken to prevent water poisoning. It can be either a substitution of part of its volume, or the installation of a new biofilter, or the relocation of extra fish.

Water parameters and the launch of fish in the aquarium

The poor quality of the aquatic environment is also a violation of the pH balance and the discrepancy between the water hardness and the usual conditions for the existence of aquarium pets.

There are frequent cases when a person brings a fish just bought at a pet store and immediately releases it from the package to his aquarium, without thinking that the pet may experience a natural shock from the discrepancy between the environmental conditions. And as a result - death in the next day.

Therefore, it is necessary not only to know the exact conditions of one or another species, but also to clarify with the seller the parameters of the water in the pet store. And if necessary, organize a procedure for adapting a new fish.

Water temperature

The death of fish can also occur due to a decrease or increase in temperature of the aquatic environment. The opinion that a deviation from a certain temperature mode by 2-3 degrees in one direction or another will not affect the health of aquarium pets is deeply mistaken. If the temperature drops, there is a danger of dying from a cold, and as it rises, the fish may die from lack of oxygen.

Lack of oxygen as a negative factor

A fish is known to breathe air dissolved in water, and it can suffocate if it is too little in aqua. Although such cases are very rare, they do happen.

As a rule, even beginners pre-acquire all the equipment necessary for the operation of the home aquatic system.

And very often, buying a powerful enough filter, they trust him not only with water purification, but also with its aeration and mixing.

Still, experts recommend to separate these two functions and ensure the continuous operation of the air compressor.

Aquarium neighbors aggression

Even if a large fish is considered a herbivore, it can easily eat small animals that fit into its mouth. For many inhabitants of the domestic water reservoir, the degree of aggression repeatedly increases during the spawning period.

There are aggressive fish because of their natural features, whose bites and bumps are very painful. All of these factors can also cause the death of aquarium pets.

When buying a fish you should not rely entirely on the opinions of sellers. As a rule, for them the most important is the fact of sale.

It is better to spend time and learn more about the compatibility of certain species even before going to the pet store. Thematic information on this subject on the Internet is quite enough.

Feed quality and overfeeding

Many novice aquarists sincerely believe that giving fish a pinch of dry commercial food every day is enough. Far from it.

Continuous feeding of the same dry food can cause the death of animals from inflammation of the stomach or intestines.

Suffice it to imagine what will happen to the human body, if it is constantly, day by day, eat the same dry food!

The diet of the vast majority of fish should be diverse, include both protein and vegetable products.

Overfeeding - a very common cause of illness and death of animals. There are two significant points here. By itself, overfeeding can lead to diseases of internal organs. In addition, food debris, settling on the ground and gradually decomposing, contributes to a sharp concentration of nitrogen compounds, a large dose of which is fatal to the underwater inhabitants of the aquarium.

Illness is the most common cause

This is true, but in this case it is necessary to distinguish two main factors.

First of allThe disease can occur as a result of all the reasons listed above. Any of them, if they do not kill the fish immediately, will contribute to a sharp decrease in immunity. It is on this basis that a disease can develop that can lead to death. If this happens, then pets should be treated by contacting specialists.

Secondly, the death of fish can be caused by the development of infectious diseases. This is the worst scenario that could be in the process of maintaining the aquarium. Why do infectious diseases appear? As a rule, there are two main reasons: the launch into the aquarium of already infected fish or the appearance of parasites in the water house. Fungal diseases, peptic ulcer disease, lepidorthosis, tuberculosis and many other infections can cause not only the death of an individual, but also the pestilence.

It is necessary to daily monitor the behavior of aquarium pets, carefully examine them, and in case of the slightest suspicion, move the diseased individual into quarantine and consult a specialist.

Unfortunately, at least once the fish die in almost every aquarist. And the reasons may be completely different. It is important to carefully analyze the incident, identifying a specific cause, and try to prevent its recurrence. And if there is not enough knowledge and experience, there is the Internet and advice from experienced owners of ornamental fish.

Simple instructions: how to care for fish in an aquarium

Aquarium - a stylish addition to the interior, which allows you to create a unique, lively atmosphere in the room. This effect creates only well-groomed and filled with bright inhabitants of the capacity. How to achieve this will help instructions how to care for the fish in the aquarium. Opinions of psychologists agree that the observation of the life of fish allows you to take a break from everyday worries and relax. Smooth movements of the inhabitants of the water world look graceful and fascinating. Therefore, the aquarium performs not only an aesthetic, but also a healing function.

Content of aquarium fish

Argued that the maintenance of fish does not require time and financial costs. Experienced aquarists will talk in detail about the complexity of this lesson, which requires care and unhurriedness. You control a small underwater world that cannot exist without competent support. For beginners, help how to care for the fish in the aquarium (point by point).

Excessive care for such pets is not required. To understand the process will help the instruction. How to care for fish in an aquarium, even children can remember.

Aquarium

The first serious oversight that is allowed at this stage is the purchase of a small aquarium, considering that the capacity of 20-30 liters will meet the needs of the beginner amateur fish. In reality, the opposite is true. Maintaining artificial biocenosis in balance is much easier in a large aquarium, at least 50-70 liters. In it several species of inhabitants can coexist and develop normally.

The next question, which will consider a brief instruction on how to care for the fish in an aquarium, is what is inside the tank. They create a cozy atmosphere for small inhabitants, starting from the ground. Small pebbles will do the job best. When selecting, take into account its caliber and color, focusing on the species of fish that are planned to contain. Inhabitants of bright shades look better on a background of gray stones.

Plants are rooted in the soil, they take nutrients from it. Flora serves as a refuge for individual fish, who love to hide from active neighbors. Artificial greens have an attractive appearance and do not require care, but give preference to natural plants.

How to choose a fish?

How to choose the inhabitants? How to care for fish in an aquarium? The manual will give answers to these questions. Decide in advance on the species composition of the ichthyofauna to simplify the process of leaving and to prevent conflicts. Focus on the size of the fish: large and small individuals can not live together.

For many decades, viviparous fish have been very popular with aquarists. They do not lay eggs, but immediately give birth to viable fry, which can independently move and feed. Characterized by these types of ease of care, they do not need to create special conditions for reproduction. However, the fish have a large range of colors and shapes.

Types of fish

If you do not know what types to choose and how to care for the fish in the aquarium, the instruction will help to resolve these issues. The most common are the following representatives of the ichthyofauna: patzili, guppies, mollies and swordtails. The conditions of maintenance and care required for them are the same, which allows you to settle them in the same aquarium. Among the fish laying eggs, speckled catfish are the most popular.

Cockerels and goldfish are classic aquarists. Beginners are more difficult to handle because they need to pay more attention. A round aquarium is not the best choice for them. These inhabitants will be more comfortable in a rectangular container. Instructions on how to care for the fish in an aquarium recommends that when creating the second tank, take some of the water from the first one. This method will help to reduce the time for settling.

Care

Instructions on how to care for fish in an aquarium, the points suggests:

  • Regular reading of the water thermometer. If there are deviations from the recommended parameters for this type of fish, the heating is turned on.
  • Viviparous ichthyofauna suitable temperature from 18 to 28 ºC. But each individual species has its own preferences. Reproduction will occur only in this narrow temperature range.
  • Control of purity and hardness of water. Every 7 days, one third of the medium is removed, replacing it with a new one.
