Goldfish how to care


Goldfish Care

If an aquarium appeared in the house, the goldfish will most likely be its first inhabitant. Many people mistakenly believe that caring for a goldfish does not require special skills, because it is often bought first. For experienced aquarists, this is really not difficult, but for beginners the fish can live only a few days. Any aquarium fish always requires the preparation and reading of special literature from its owner.

Content of goldfish in an aquarium

The capacity of an aquarium for a goldfish must be at least 50 liters. In such an aquarium, you can settle up to 6 individuals, it is dangerous to settle more - they most likely will not survive due to excessive pollution. You can share your neighbors with goldfish. It may well get along with them scalar, catfish. Before you start an aquarium, familiarize yourself with all possible diseases of goldfish. Knowing the symptoms will help you quickly recognize the disease and save the fish. Here are some basic rules for keeping a goldfish in an aquarium:

  • Do not skimp on the "living space". For a goldfish you need a large aquarium. This is more convenient, it is easier to maintain biobalance.
  • Buying the right filter. You need to choose an aquarium filter with the ability to pump air. A goldfish needs oxygen-rich water.
  • The ideal bottom for keeping fish is gravel. It contains beneficial bacteria. These bacteria consume ammonia and thus lower its level in water. Try to choose coarse gravel, small fish can eat.
  • Do not rush to populate a new aquarium. Let the biobalance settle in it. You can run snails and catfish there for a while. They a little "pollute" the aquarium, then the water will be suitable for running the fish.
  • Periodically check the following water tests: pH level (it should be 7-8), ammonium level, nitrites and nitrates (up to 40 is considered normal).
  • Place a thermometer. Goldfish belongs to tropical species. In cold water, it simply will not survive. The ideal water temperature for goldfish is 21 ° C.
  • Change water regularly. For an aquarium of 5-10 liters, it is enough to change 20-30% of water. Doing this once or twice a week is enough. In the new water, you can add a special conditioner. Complete replacement of water can disrupt the biobalance and harm the inhabitants of the aquarium.

Goldfish food

Feed the goldfish should be a special feed. Food for goldfish produced in the form of flakes or granules. If you want to pamper your pet, you can add to the diet finely chopped lettuce or pieces of hard-boiled egg. Goldfish do not know the measures in food and overfeeding them is very simple. In order to avoid such troubles, carefully measure the amount of food that the fish managed to eat during the first three minutes of feeding. In the future, do not give her more.

Algae for goldfish

It is best to use artificial plants. From living plants Javanese moss is best suited. Prefer sedge plants with strong and elongated leaves. The wider the sheet, the better. If you decide to keep a goldfish in a small aquarium, it is better to completely abandon the plants or simply use a few artificial decorative elements.

Caring for a goldfish is very scrupulous and difficult only at the beginning. When you learn a little about all the tricks of this business, the eye will delight the beautiful clean aquarium and its well-groomed inhabitants. By the way, in the teaching of feng shui, a goldfish is a symbol of harmony and prosperity. In addition, it is a symbol of material well-being, so take good care of your darling.

Goldfish: content at home

Goldfish, which marked the beginning of aquarism as such, are now, unfortunately, out of fashion. Professionals consider it uninteresting and not worthy of attention, and only a few connoisseurs and experts of this type remain. Therefore, the lot of most cinchons is kindergarten or hospital aquariums with plastic plants or a short life in a beautiful glass given to a person for the holiday, far from fish problems. Let us treat this beauty with the respect and interest that she deserves, and see what is necessary for her for a long and happy life near us.

How demanding are goldfish to conditions?

Opinions on this score are opposite. Some believe that this is a patient, practically unkillable, fish that survives in any conditions, suitable for beginners and people who do not want to invest in the aquarium a lot of effort and money. Others, on the contrary, argue that the content of gold must comply with a number of fairly tough conditions, and they are no doubt right. A goldfish should not be started by someone who is not ready to make efforts for its comfortable existence. And the most important condition for the maintenance of these fish is an aquarium of a sufficiently large volume.

Volume and shape of the aquarium

In Soviet literature of the last century in aquariums it is indicated that one goldfish should have 1.5-2 dm3 of water surface, or 7-15 liters of aquarium volume (15 liters per fish is considered to be a small landing density). This data migrated and in some modern tutorials. However, it should be noted that Soviet books were written about goldfish of domestic breeding, which for many generations lived in aquariums, and as a result of breeding were adapted to such conditions. At the present time, the vast majority of goldfish comes to us from China, Malaysia and Singapore, where they are massively bred in ponds. Accordingly, they are not adapted to life in small volumes of water, and even to a sufficiently spacious aquarium they need to be adapted, and a volume of 15-20 liters means death for them within a few days.

Experts who today work with goldfish brought from Asia have empirically established:

The minimum volume of an aquarium for one individual should be about 80 liters; in a smaller volume, an adult fish will simply have nowhere to move. For a couple - 100 l.

In large aquariums (200-250 l), with good filtration and aeration, the density of planting can be slightly increased, so that the volume of water is 35-40 liters per individual. And this is the limit!

Here, opponents of half-empty aquariums usually object that in zoos, for example, goldfish are very densely packed in aquariums and at the same time they feel great. Yes, indeed, this is the specificity of the exhibition aquariums. However, one should keep in mind that behind the frame there are several powerful filters with which this monster is equipped, the most severe schedule of water changes (up to half the volume daily or twice a day), as well as the regular ichthyopathologist veterinarian for whom there is always work.

Regarding the shape of the aquarium, the classical rectangular or with a slight curvature of the front glass is preferred, the length should be approximately twice the height. In the old Soviet literature it was stated that water should not be poured above the level of 30-35 cm, but as practice shows, this is not critical. Goldfish live well in higher aquariums, if they have the appropriate width and length (tall and narrow aquariums - screens and cylinders - are not suitable for keeping gold).

What types of fish are compatible gold?

The answer to this question is unequivocal - the best option would be a specific aquarium where only goldfish live. Moreover, even short-bodied and long-bodied gold lodging is often not recommended together, but representatives of other species of fish are out of the question. Either the neighbors will harass the scones, damaging their eyes and fins, or the neighbors themselves will be uncomfortable, as the aquarium with goldfish is a very peculiar habitat. In addition, small goldfish can simply swallow.

Water parameters, design and equipment of the aquarium

Goldfish comfortable with the following indicators of water:

  • temperature 20-23 °, for short-body forms slightly higher, 24-25 °;
  • pH of about 7;
  • stiffness not lower than 8 °.

The soil in the aquarium should be chosen so that the fish, digging into it, do not choke - its particles should be without sharp, protruding edges and either larger or much smaller than a fish mouth.

In the aquarium with goldfish must certainly be living plants. Consuming nitrogen, they have a positive effect on the ecological balance, are an additional substrate for bacteria performing biofiltration, and also serve as vitamin supplements for fish. Goldfish mercilessly dig in and gnaw plants, but this should not be the reason for refusing to populate the aquarium with lively greens.

Lemongrass, Anubias, cryptocoryne, Alterner, Bacopa, sagittaria, Javanese moss get along well with gold. It is recommended to plant the plants in pots so that the digging does not damage their roots. And as a top dressing, specifically give the fish a duckweed, Riccia, wolf, and a hornpole.

Mandatory good round-the-clock aeration. At a minimum, an aerator on the filter should be turned on; it is better to additionally have a compressor. If the aquarium has a high density of living plants, a powerful light and the supply of carbon dioxide is organized (in such conditions the leaves of the plants should be covered with bubbles of oxygen emitted by them), then the aerator is turned on only for the night.

In the design of the aquarium should not use large objects of decor - snags, grottoes, etc. Goldfish do not need shelter, but the fins of the valehvostoy, telescope eyes, growths about them are easy to injure, besides the shelters take up space for swimming.

Filtration and water changes

It is generally recognized that goldfish are a large biological load on an aquarium. Simply put, they are dirty, producing a huge amount of waste. Their habit of constantly rummaging in the ground, raising the dregs, also does not add cleanliness to the aquarium. In addition, goldfish excrement has a mucous consistency, and this mucus pollutes the soil and contributes to its rotting. Accordingly, in order to keep the water clean and transparent, a good round-the-clock filtration system is required.

The filter power should be at least 3-4 volumes of the aquarium per hour. The best option would be a canister external filter. If you can not buy it, and the volume of the aquarium does not exceed 100-120 liters, you can get by the internal filter - always with multiple sections and a compartment for ceramic filler.

Porous ceramics is a substrate for bacteria, which process poisonous ammonia released by fish into nitrites and then into much less toxic nitrates. In addition, the substrates for these bacteria, a stable amount of which is vital for the well-being of the aquarium, are soil and aquatic plants, especially small-leaved ones. Therefore, it is desirable to have a lot of plants, and the soil fraction should not be made too large.

In order for the colonies to not collapse when cleaning the aquarium, some rules must be observed: the filter sponges are washed in the aquarium water (the sponges are washed quite often, about once a week), the siphon of the soil is also weekly, done carefully, without mixing it layers, ceramic fillers for biofilters are always partially changed.

Even with high-quality filtration in an aquarium with goldfish, it is necessary to do weekly from a quarter to a third of the volume of the aquarium, and more often if the density of fish landing is violated. The fishes of this species tolerate fresh water well, so there is no need to defend it for more than a day.


Now that we have dealt with the main, most difficult and costly content of goldfish, we can talk about how and what to feed them.

They are usually fed twice a day, giving the amount of food that fish are able to eat within 3-5 minutes. Dry flakes and granules are recommended to alternate with vegetable food - spinach leaves, lettuce, boiled vegetables and cereals, fruits (orange, kiwi). Sometimes you can feed pieces of meat or liver, as well as frozen motils. It is necessary to take into account that the pellets of dry food should be soaked for 20-30 seconds in aquarium water, and thawed frozen food before giving them to fish. Very useful regular feeding live daphnia, which you can grow at home. In addition, as mentioned above, it is always better to have special food plants in an aquarium. Once a week, fasting days are arranged.


Diseases of goldfish are a subject for a separate article, but here we briefly consider only signs that may indicate that the fish are sick or have severe discomfort:

  • loss of appetite;
  • lowered dorsal fin;
  • bulging scales, red or black spots that quickly appear, ulcers, rashes, mucous or cotton-like plaque;
  • distended abdomen and bulging eyes stronger than usual;
  • unnatural behavior: the fish stays in the corner of the aquarium for a long time, lies at the bottom, rolling over on its side, or swimming near the surface, swallowing air from it;
  • rolling over while swimming.

It should be noted that with proper maintenance of health problems in goldfish are quite rare. If you initially create good conditions for these animals (a spacious aquarium with live plants and powerful filtration), then care of them will be available to the beginner or even to the child, and for many years they will delight their owner with bright appearance and funny behavior.

What are goldfish, you can learn from the video:

Goldfish care and maintenance in an aquarium

We treat a golden fish with special trepidation and tenderness, remembering the well-known fairy tale from childhood. Perhaps that is why it is presented as a gift for birthdays, festive dates, packed in transparent bags, in live wall panels or crystal glasses, forgetting that it is a living creature. Meanwhile, goldfish cares good loves, it needs special conditions for the content. This is a very common and many favorite type of aquarium fish, characterized by bright decorative and large size. It was removed in China, where even in the Middle Ages it was decorated with open artificial reservoirs in the gardens of Chinese emperors and nobles. Until now, there is a special relationship to the goldfish in this country, it is decorated with porcelain dishes, decorative mosaic panels, silk fabrics, etc.

In China, the main representatives of the goldfish species were derived: voiletails, fantails, black, Chinese and calico telescopes, red cap, pearl, red lionhead, etc. The golden-red, bright orange, velvety-black species of this ornamental fish are really an amazing decoration of aquariums.

Content of goldfish in an aquarium

The first thing you need to know when acquiring a gold house is that it needs a sufficiently large spacious aquarium. Experienced aquarists believe that for a comfortable dwelling of one individual, it takes about 40 liters of water. Here we must also take into account that this fish grows to a rather impressive size. Therefore, for the maintenance of several fish, you will need an aquarium that is at least 100 liters in size. In large aquariums, moreover, it is easier to maintain a biological environment useful for its inhabitants, it is necessary to change the water less often, and the level of pollution in a large aquarium is much lower, which is important for keeping large aquarium fish.

After acquiring the right size of the aquarium, it is necessary to fill in the soil and fill it with water. For goldfish, the soil in the form of small pebbles is the most suitable, but its fraction should not be too small, otherwise the fish may swallow a pebble. After the aquarium is filled with water, install the equipment. For a goldfish, oxygen dissolved in water is needed, so it is very important to install not only a water filter, but also a compressor that pumps air.

Fishes are launched into the aquarium in a few days, letting the water draw in, saturated with oxygen. Snails can be launched into the aquarium beforehand to create the necessary bio-environment in the water. Goldfish care good loves and appreciate caring for her. In good conditions, these ornamental fish grow large and become amazingly beautiful.

Goldfish: care

It is very important to feed the goldfish correctly. There is a special food for this type of aquarium fish. You can vary the diet by adding small pieces of boiled egg to the aquarium, but at the same time make sure that the fish eat everything up. The main thing in the diet - to comply with the measure and not to overfeed the fish, remembering that the goldfish - glutton. In order to correctly determine the amount of feed, it is necessary to observe for three minutes during feeding how much fish are eaten, and at subsequent feedings give them exactly the same amount.

Goldfish prefers warm water. The temperature of the water in the aquarium should not be below 23 degrees. To determine the temperature of the water, you need a thermometer, which is lowered to the bottom of the aquarium. Of course, you need to monitor the cleanliness of the water, collect the remains of fish from the bottom, and at least once a week do water replacement by one third of the volume of the aquarium. Goldfish care so appreciate.

How to determine the sex of a goldfish

In the conditions of a home aquarium, you can successfully breed goldfish. It is easy to determine the sex of goldfish, just look carefully at the gill covers. In males, they are covered with small white dots, similar to semolina, while females do not have such points.

Aquarium fish - telescopes

Fish telescope - a kind of goldfish, in the wild is not found. As is known, goldfish appeared as a result of selection of wild carp. According to reliable data, the telescope fish was bred in the XVII century in China, from which it came to Japan. The most prominent part of the animal's body is large, bulging eyes located on the sides of the head. Due to the unusual shape of the eye, the fish got its name. Unfortunately, these eyes themselves are very vulnerable in the aquarium, they can be damaged by random objects. For this reason, keeping a pet requires maximum care. Caring for fish imposes some restrictions and rules that help protect its health.


The telescope of the fish has an oval shape, identical with other representatives of the tail specimen. The symmetry of the body is short and wide. The head is large with bulging eyes, lush fins.

Modern razvodchiki sell small telescope fish of different colors and shapes - with short or long fins, red and white flowers, and, of course, black ones. With age, black telescopes change color scales.

The size of telescopes varies on average from 15 to 20 cm within the aquarium. They live in captivity for a long time, about 15 years. Fish living in artificial ponds, can live up to 20 years.

Content Features

Similar to their relatives, goldfish, telescopes get along in cool water, but they are not recommended to be bred for beginners in aquarism. The point is in the vulnerable eyes, which in addition to the large eyeball, they see almost nothing. Its content is not so simple: you have to look for special food, plants and soil that would not damage the pet's tender body.

On the other hand, caring for telescopes is not difficult if you are extremely careful with them. Like other types of goldfish, they are tolerant of changes in the aquatic environment, can live both in the garden pond and in the glass aquarium. Compatibility is possible with slow, peaceful fish that do not take away their food. It is recommended to settle in spacious aquariums at the rate of 50 liters for 1 fish and more than 150 liters for several individuals. The tank should be safe, without a large number of kryag, sharp objects. They use rounded pebbles of medium size or coarse sand as soil - telescopes like to rummage in the ground. It is important that they do not swallow large parts. Soft plants gnaw, hard-leaved plants - a good choice for their "house".

Watch the video, revealing the features of the content of the fish telescope.

In the aquarium, you should install a powerful external filter that will remove numerous wastes after pets. The flow is important to pass through the flute, as we know, telescopes float badly. Choose wide containers with a large surface area - through it there is a constant gas exchange.

Do not forget about updating 1/5 of the water once a week. Permissible water parameters: temperature 20-23 degrees Celsius, hardness - 5-19 o, acidity - 6.0-8.0 pH. Not particularly sensitive to the conditions of detention, but quality care for them involves clean water and the absence of sharp surfaces.

What to feed?

Aquarium telescopes are unpretentious in feeding: they feed on live, frozen and artificial food. You can give granules, artemia, bloodworm, tubule, daphnia. Due to poor eyesight, they do not always notice the food without eating it. When feeding fish with artificial food, it is possible to ensure maximum saturation, as they find food for a long time at the bottom of the tank. And such feed slowly disintegrates and does not rot.

Who can live in captivity?

Telescopes can be called friendly fish that behave adequately in relation to their neighbors. Compatibility is proven with related species of fish: voile tail, shubunkin, oranda, goldfish. Such cold-loving fish, not aggressive, do not leave behind a lot of waste.

Compatibility is negative with Sumatran barbs, ternets, burbusi denison, tetragonopterus. These fish can intimidate them, tear off their fins.

Admire the bright telescopes.


The reproduction of telescopes is possible in an artificial reservoir in the springtime, when the water is warming. As in the reproduction of goldfish, the female and the male telescope are planted for two weeks in separate aquariums, giving live and artificial food. Before settling in spawning, they are satisfied with the fasting day. Spawning occurs in fresh and softer water with a temperature of 23-25 ​​degrees.

The required spawning volume is 50 liters, a separator grid and several stile-leaved plants are placed there. Usually one female and 2-3 males spawn. The female lays many eggs - more than 2000. Incubation lasts 3-4 days. 5 days after spawning, the larvae will hatch, which will swim in a few days if the water temperature is from 21 to 26 degrees Celsius. The fry are weak and helpless, barely noticeable. Starter feed - live dust. Later you can eat artemia and rotifers. Caring for fry requires constant observation in the spawning aquarium - in order to prevent cannibalism between brothers, large fry should be separated and settled separately from smaller ones.

Goldfish can be fed with all kinds of food, since they eat almost all food.
You can feed them with ready mixes and homemade food. If you prefer the second option, throw small pieces of food to the fish. You should not overfeed them, no matter how hungry they looked at you through the glass of the aquarium.
Fry and young animals are usually fed dry and live food. Vegetable food is the basis of nutrition for adult fish.
Additionally, fish can be given in a small amount of shrimp, squid, as well as small pieces of fish fillets.
It is not recommended to give fish the meat of warm-blooded animals and offal (liver, heart, etc.)
Adult fish can be fed with live food, but their share should be no more than 10%. The most recommended feeds are: earthworms, tubule, bloodworm, daphnias, corret.
Dry feed goldfish need to fill in dosed portions several times a day. If you pour a lot of dry cereal fish, they do not have time to eat them immediately and the food swells. If a fish eats such swollen flakes, it can get sick. You can feed and cereals, boiled in unsalted water, for example, semolina, millet, rice, buckwheat. Do not forget to thoroughly wash the cereals before cooking.
Goldfish have a great appetite, but feeding them is not worth much. It is best to give them food no more than twice a day in small portions. It is recommended to alternate food, it is necessary to give dry food, both live and vegetable. Live and vegetable food fish should eat in twenty minutes, dry food - ten minutes. If the fish feed is not finished, it should be removed immediately. Long-bodied goldfish take a little longer to eat than short-bodied fish.
Determination of single portions can be very simple. First you need to throw a small amount of food, then look at how the fish will take over the food. If they become calmer, you need to stop feeding.
You should know one more rule, it is better to feed the fish rather than feed them.
Goldfish remember their master and even take food from his hands.

Who would have thought that the progenitor of a goldfish - the favorite of many aquarists - is a common crucian, and even a silver one? The whole pedigree of goldfish with all its varieties began with it.
If you decide to purchase these pets for maintenance in your aquarium, then you better choose a larger capacity. There is an opinion that the aquarium of a classic round shape, which opens from above or without a lid at all, is “the most it” for goldfish. But it is not. It is recommended to use four or hexahedron with a lid under which the lighting fixtures are attached.
Therefore, for the maintenance of goldfish is better to buy an aquarium with a capacity of at least 50 liters - they are easier to maintain biobalance. It can contain 6-8 fish, if you provide your pets with continuous air blowing, and the water depth will not exceed 30 cm. In an aquarium of 10 liters you can keep no more than two adult fish.
All types of goldfish love to dig in the ground at the bottom of the aquarium. To prevent the soil from being scattered in a chaotic manner, use materials that are not very light - for example, large pebbles. In an aquarium with goldfish, it is recommended to plant plants with hard, large leaves and a good root system (for example, valisneria, nugget, sagittarium, elodea).
Optimum for goldfish is a water temperature of 18-21 degrees. You can add salt to the water - for the best well-being of fish - 5-7 g / l. It is advisable to regularly replace part of the volume of water, especially if there are no devices for aeration — then 1/3 of it should be replaced, and the more often the better.
Goldfish can rightly be called gluttons. They eat everything and in large quantities. As a rule, they consume food of both plant and animal origin. There are ready-made feed specifically for goldfish in the form of flakes and pellets. They are good enough to use, because in addition to the essential nutrients with a large part of carbohydrates, these feeds are balanced and contain natural additives that improve the color of yellow, orange and red colors.
Remember that when feeding with dry food of any kind they should be given in small portions several times a day. After all, they have a feature when they swell into the fish's esophagus, significantly increase in size, cause constipation and dysfunction of the digestive organs. You can first hold the dry food for some time (10 seconds - flakes, 20-30 seconds - granules) in the water, and only then give them to the fish.
For a change in the diet, goldfish are given live food. Coretra, pipe clerk, large bloodworm, earthworms - all this goes away in seconds. But remember that in no case should a goldfish overfeed. Do not throw her food more than she can eat in 3 minutes. A good time to determine the amount of feed - this is the first feeding of your pet. You only need to watch her and determine how much food she has eaten during these three minutes.
Sexual differences in goldfish are weakly expressed, and it is possible to distinguish the male from the female only during spawning, when the male has a “file” on the front rays of the pectoral fins and warts on the gill covers. Goldfish are ready for reproduction after a year, but it is better to wait for their full development, the maximum brightness of the color and the fineness of the fins is about 2-4 years old, and then breed. Males begin to actively pursue females. At this time, they need to plant and feed a variety of fortified foods.


You come up to a goldfish, and politely ask, "a goldfish, a magic one, I want you to take care of all the living creatures in the house!" ... and look in a dream, the wish will come true. But when you wake up remember to remember, it was just a dream.

Goldfish unpretentious. True require a sufficient amount of aquarium. They need a minimum of 10-15 liters of water per fish. The larger the aquarium, the larger the fish grow, and it is more convenient to observe them in a large aquarium. The filter is desirable in any aquarium, not only with goldfish, otherwise it will be difficult for you to maintain the purity of the water. Now the choice is huge and there are inexpensive filters that purify water quite normally. I have the simplest internal Tetra filter and everything is fine. Goldfish feed any food, I fed live and frozen bloodworms, and in case of absence, you can feed them with regular dry food. The main thing is not to overfeed, and then the fish are big gluttons, it is worth going to the aquarium, immediately everyone swims upstairs and starts begging for food.
Do not forget that goldfish grow large enough, so do not plant densely aquarium plants, they need a place where they can swim freely.
With good care, goldfish live for a long time, I heard that they can even live for several decades, I don’t know if this is true or not. My biggest lived about five years, grew quite large.
The cost is different, but if you buy small fish (they then grow), it will be cheaper than if you immediately buy large adult individuals. And the types of goldfish are also different, the cost also depends on it. I in Moscow bought calico riukins for 75 rubles. Other types are more expensive.

Natalia A.

With 10-15 liters on the fish will not last long! At least 50 SPECIAL ONES! liters with a powerful filtration system and good blowing, intensive changes with a siphon, in nasty conditions do not live long, are delayed and often sick, fish with high metabolism, requiring good care and proper balanced nutrition, plant food should be not less than 70%.

How to care for goldfish

I want a goldfish in a round small aquarium, how much will it cost to enjoy? How to care?


however, the goldfish will be crowded. maybe better cock they are very beautiful and do not require large amounts of water, as they breathe atmospheric air. You can also put there:
1 lalius or 1 gourami or 1 macropod. just not all together :)

Harmful Victoria

decently, I had goldfish, but everyone died ((
By the way, a round aquarium is harmful to fish, even though it is very cool)
care needs constant - water change, filters, oxygen include, plants to buy, feed ... small, small, and care like an elephant)))

Alexander Khanin

pleasure is not very expensive ... about 1500-2000r. In this amount, you buy an aquarium + a goldfish + a compressor and a water filter / heater ... as well as the ground and a few water industries must be kept up))) just care to feed ... follow the water temperature ... and clean the aquarium ... all procedures are measured how to do it more precisely, you can learn from the special booklet usually in the ZOO store such are sold ... and care for Golden Fish is called so)))


1000 -1500 Rubles Goldfish are best kept separately from other fish species, especially small and fast ones, which can intercept most of the food, and pugnacious ones, such as macropods, cychlasmas and barbs, which can damage the big eyes and fins of their clumsy, innocuous neighbors. . For a pair of two-three-centimeter fry small vessels, containing a bucket of water (10-12 liters), are quite suitable. However, the larger the aquarium, the better the fish feel and the easier it is to take care of them. If in a four-buried aquarium, voiletails or telescopes grow in length up to 10-12 centimeters and can multiply, then in a bucket aquarium they will forever remain dwarfs.
It is harmful for goldfish to be in a round aquarium: there is not enough space for them to swim, there is not enough oxygen for breathing, and they can become blind from abnormal refraction of light by a convex glass. In a round aquarium it is difficult to place a filter and an air dispenser without spoiling the decorative appearance of the vessel. Fish feel much better and are less sick in a spacious rectangular aquarium, which is easy to decorate with smooth stones and aquatic plants.
Good aeration (air blowing) and water filtration are important conditions for proper keeping of goldfish. 1/3 of the total volume of water should be, regardless of the work of the aerator (microcompressor) and filter, weekly change to fresh. In an aquarium with a volume of 40-50 liters (with a water layer of no more than 30 centimeters), 6-8 fish can be kept while continuously blowing water through the air. Since the main saturation of water with oxygen occurs through its surface, it is advisable to calculate the surface area per fish. A decimeter of body length for short-bodied rocks requires at least two square decimeters of the water surface, and for long-bodied rocks - at least one and a half square decimeters. If there is no purge, but the water is partially replaced with fresh water every day, this rate should be doubled, and if the water does not change at all, it is tripled.The norm relative to the surface of the water should be considered as approximate, since it depends on the number of plants, water temperature, etc.
If the fish swim, raising their mouths to the surface, trying to capture the air, then the water is not sufficiently saturated with oxygen. It is necessary to increase the purge or change part of the water to fresh.
Partial replacement of water in the aquarium is better to make tap water in a separate container for 24 hours. With a large non-blown aquarium and a small number of fish (if each has about 15 liters), it is recommended to replace about 1/10 of the volume with water taken directly from the aqueduct daily.
The cooler the water, the more oxygen can be dissolved in it. Therefore, in hot weather, the fish may experience oxygen starvation. The best water temperature for them is 15-20oC. Plants play a major role in supplying oxygen to water in an aquarium without purging. However, the surface of their leaves is contaminated by suspended particles in the water, and tender plants are simply eaten by goldfish. Plants with rigid leaves and a good root system are suitable for an aquarium: Vallisneria, Japanese sagittria, Anubias - or the most hardy, for example, Elodea. As a soil for plants, it is better to use fine (with a pea) gravel or pebbles, which are almost not scattered with fish.
It is better to place an aquarium with goldfish near a sunny window: without sufficient lighting, the bright coloring of the fish dims, the plants wither. Natural lighting can be replaced by electric.
Feed the goldfish need a variety of foods. In the diet should include plants: chopped lettuce, Riccia, wolfia, duckweed. The best food is the bloodworm, the earthworm (too large specimens cut into pieces), daphnia. Live food can be replaced with meat that has been scraped or rolled through a meat grinder, made in half with white bread into small balls. It is permissible to feed fish cooked steeply, crumbly, washed in fresh water cereal: buckwheat, oatmeal, millet
