How many live aquarium goldfish?

Fish - being sensitive to everything that surrounds it. To notice her illness, discontent or hunger is very difficult. Proper care for her is the only way to prolong and simplify her life.

How long do golden fish live?

The lifespan of a fish depends on many factors. There is a certain pattern: small inhabitants of aquariums live 1-5 years, medium (5-10 cm) - 10-12 years, large-sized - 15 - 35 years. Catfish, carp, and sturgeon can outlast a human being. Breeding karrezubye representatives, for example, Notobranchus, live in puddles, die immediately after the pond dries out, the eggs survive. Even if you breed them at home, they will live only a few months.

Most experts are inclined to believe that the average age of a goldfish is 4-5 years, in good conditions and professional care a pet can live 10-15 years. There is information that in one of Moscow zoos the fish has lived for 34 years, in the UK - 43 years.

Factors that affect the life of the "golden" inhabitants of the aquarium

How much live aquarium goldfish, directly affected by water temperature. Fish are cold-blooded animals, that is, their body temperature is almost equal to the temperature of the water in which they are located. Warm water accelerates metabolic processes, the body will wear out faster. The color of older individuals is more colorful compared to the young.

Can kill your pet and improper feeding faster. Remember that food should not be only dry. Overfeeding is more harmful than underfeeding. Periodically it is necessary to do fasting days for the "golden" beauties.

The population of the aquarium and its size is important for the normal existence of fish. Before buying individuals, make sure that they are compatible and will not survive each other. Do not forget to change the water. Professional aquarists say that a tank of 150-200 liters is ideal for fish.

Following these rules will significantly increase the chances of your pets becoming long-lived.

How many live aquarium fish?

Each aquarist wonders how many aquarium fish live. Everyone needs to know this. If you are not sure that you want to keep the aquarium for a long time, get fish with a short lifespan. For experienced breeders, the number of years is important to count the spawning that the fish will have time to implement.

Several things can affect the lifespan of aquarium dwellers:

  • The size;
  • Water temperature;
  • Overfeeding;
  • Undernourishment;
  • Conditions of detention;
  • Neighborhood.

Size of fish

The main criterion is the size of the fish. By this indicator, you can judge how long you can admire your pet in the aquarium. The smallest inhabitants have the lowest border, whose dimensions do not exceed 5 centimeters. For example, neon, guppy, swordman. They live from one to five years.

Record small sizes were found in South American small fish - zinolebias. The length of her life depended on the rainy season, as soon as a drought occurred - zinolebias was dying. The only thing that saved the fish from extinction - the timely throwing of caviar. During the period of high water, she managed to appear, grow, spawn, and die.

Fish, whose dimensions are defined as medium, can live up to 15 years, and some representatives over 25, for example, piranhas. Therefore, starting such pets, be prepared for a long neighborhood.

Interesting fact, males live significantly longer than females. Sometimes, the difference reaches almost two years. Breeds are known where the female dies after the birth of fry. Of course, no one is immune from the unsuccessful throwing of caviar or a number of diseases, but most often this is observed in sword bearers and gupeshek.

Aquarium water temperature

The temperature of the water in the aquarium affects the lifetime. Cold-blooded animals can not control the temperature of their body on their own, so water sets the rhythm for most processes in the body. The body temperature of the fish is equal to degrees of water. Thus, the higher the score, the more intense the metabolic processes in the fish's body, and, therefore, life expectancy is reduced. Sometimes this figure reaches several years.

It is proved that if you rarely change the aquarium water, the concentration of harmful substances in the water will be above the norm, which would entail a reduction in the life of the inhabitants. Use distilled water whose chlorine content is close to the permissible value. Bad water can lead to dysfunction of the respiratory organs and diseases of the digestive organs.

Diet

On how much live aquarium fish, affects feed. It's about overfeeding and underfeeding. Fish obesity is a fairly common problem. Most often this happens in a family with young children who are interested to look at the inhabitants of the aquarium who eat the food. Don't underestimate underfeeding. Due to the lack of nutrient and vitamin elements, they do not have enough energy for a normal existence. If in doubt about the right amount of feed, smell the water. If you are overfeeding fish, the water will have a specific smell. Ideally, it should not emanate any flavor.

Overfeeding occurs if:

  • Water has a rotten smell;
  • Rapidly cloudy;
  • The film is formed;
  • Algae have slippery patina.

In order to avoid the death of your favorite fish and increase the number of years of cohabitation, it is necessary to observe the measure in feeding, then the life expectancy will correspond to the figure indicated in reliable sources. The feed should be enough for the fish to eat it within a few minutes after serving the food.

Proper selection of neighbors

The number of years lived can vary according to the nature and type of neighbors. When you create a dream aquarium, it is not enough to know the aesthetic criteria and dimensions, it is necessary to evaluate your preferred habitat zone and character. If fish can get used to the hardness of water, then it is unlikely to endure the unacceptable habits of the neighbors.

The combination of fish size is one of the fundamental rules of an aquarist. Big fish are able to eat small fish or fry, regardless of taste preferences. Before you start the new inhabitants - carefully examine the compatibility.

Overpopulation adversely affects the life expectancy of aquarium fish. The negative effects of overpopulation:

  • Lack of feed;
  • High competition;
  • Lack of oxygen;
  • Frequent illness;
  • Aggressive behavior;
  • Fight for leadership.

All this can lead to the death of fish. It is important to observe the number of liters for each individual. Otherwise, the life of the fish can be reduced. Be wary of cocky breeds, they are capable of killing an opponent in the fight for leadership.

Beautiful but capricious goldfish

To date, aquarium fish, or rather, their varieties are quite numerous and varied. But always the most important among them are considered, in fact, the legendary goldfish.

Interesting golden inhabitants of the underwater world are far from simple creatures. And in order to ensure proper care, to maximize their life expectancy and prevent diseases (do you wonder how many years such fish live?), Finally, in order to ensure their reproduction, many nuances should be taken into account.

External description

Typically, the length of goldfish comes to 30-35 cm. However, in aquarium conditions, the indicators are much more modest: you rarely find fish over 15 cm.

The body of these aquarium fish is slightly elongated in length, has the shape of an ellipse, flattened from the sides.

As for the fins, the dorsal is very long, starting in the middle of the body. The anal fin is relatively short (it is related to the tail). Usually these creatures have red, slightly reddish or completely yellowish fins. The belly, as a rule, has a yellowish tint, the sides are golden, and the back is red-golden.

However, there are various types of these aquarium dwellers that may have pale pink, red, black, white and even spotted color.

Content Features

Goldfish require carefully selected aquarium conditions. First of all, you need to understand that keeping one fish requires at least 50 liters of water. However, as the number of fish in an aquarium increases, an increase in their population density is allowed.

At the bottom of the aquarium should be a coarse-grained soil, because the fish love to rummage in it. Pebbles need to pick rounded, which do not have sharp edges. The content also implies plants, only it is better to let them not with small leaves, since the dirt lifted from the ground will settle on such leaves. Floating plants will also be useful - they can be used for feeding.

Now let's talk about the parameters of water: its temperature varies from 16 to 24 degrees (lower temperature is needed in winter, as the summer period approaches, it is necessary to gradually increase the temperature of the water); rigidity - at the level of 8-18 degrees, the acidity is needed around 7.

In general, water should be given maximum attention (after all, its quality affects even the life expectancy of the fish themselves, i.e. it depends on how long the fish in question live). It must be rich in oxygen, must be clean. Every day should be replaced about a tenth of the water. Without a filter can not do. Inadequate water quality provokes disease.

Speaking of longevity. How long do these funny inhabitants of the water live? No one can name the exact period how long they live, but there is a case when a goldfish has lived to 34 years without a single disease. How long do they usually live? From 3 to 10 years. The length of life of these creatures depends on what their content.

Now consider compatibility. Here it is necessary to take into account the variety of goldfish, because not all species have complete compatibility with other fish. In addition, even the compatibility of fish with each other is not always observed. Check compatibility with one or another fish is still not worth it. In any case, peaceful and calm neighbors, not too large, will ensure almost absolute compatibility.

How to feed?

To feed the fish in question is very difficult, especially for beginning aquarists. Why? Goldfish are very voracious creatures that almost constantly ask for food. You can say this: how many live, eat so much. However, feeding them too often is strictly forbidden because they develop diseases.

The recommended feeding regimen is once or twice a day (otherwise diseases are observed). Portions should be made small: let the fish eat everything for about seven minutes. But what can you feed?

The answer to this question is very simple: you can feed almost everyone, because goldfish are omnivorous creatures. Because of this, the diversity of their food suggests the presence of:

  • live food;
  • specialized dry food;
  • plant foods (i.e. need plants).

It is advisable to buy live food frozen (this will exclude the likelihood that the fish will have the disease), then to thaw it and feed them to the fish. Dry it is recommended to pre-soak in a small saucer with aquarium water. Plants before you start to feed the fish should be scalded (this will also prevent disease) and grind. It is noteworthy that adults can eat the plants even if they are not crushed.

What plants can be? It should be particularly highlighted salad. The leaves of this plant are very fond of fish. Plants can be perfectly supplemented with fruit.

In general, it should be noted that the issue of nutrition of goldfish should be approached very responsibly. It is very important to feed these aquarium inhabitants properly and in a timely manner. If all requirements are met, fully-developing adult fish will easily endure a two-week hunger strike (in case of leaving for a vacation or a business trip).

In addition, there is the possibility of leaving the fish for a longer period if there is such a need. Then they can be left in the aquarium a little more of the horn.

We also point out that a number of experts recommend supplementing the ration of goldfish with cereal porridge. Such porridges should be cooked in water without salt. It is desirable that they were crumbly.

Breeding issues

Having thoroughly studied the basic rules that ensure the proper maintenance of goldfish, one should also consider the issue of reproduction.

So, if you wish to reproduce these aquarium dwellers should stock up on a spawning aquarium. Such an aquarium should be about 80-100 cm in length (different types of fish require to some extent different care when breeding). Spawning need to close on top. It is important that it be planted with small-leaf bushes.

Water must be fresh, saturated with oxygen. Its performance is generally similar to those established in an ordinary aquarium.

In early spring, the fish begin mating games. It is recommended to plant them for 2-3 weeks, providing a good feeding. Then, two or three males and a female should be selected for spawning.

In goldfish, spawning usually occurs in the morning and lasts until the middle of the day. How is everything going? The female swims among the plants (or directly above them), where she spawns. This calf is then fertilized by the male.

After that, the fish should be removed from the spawn (remember about compatibility: not only different species can not live together, but also individuals of different ages), and the eggs should be provided with the right care. This implies, above all, the protection of the eggs from sudden fluctuations in temperature, on which the life expectancy of future fish depends. How long do the eggs live? After two days the fry already appear, and on the 5th day they swim boldly.

These are the key features relating to goldfish. Recall: you need to take into account also that these aquarium inhabitants are very diverse, their different types have different compatibility with other fish, but in any case they are voracious. In addition, often goldfish affect certain diseases. By virtue of all the above, it is rather difficult to ensure the content of these creatures. But competent care greatly facilitates the situation. In addition, we noted that the correct conditions of detention affect the lifespan of the fish. And how much do these fish live with you?

Which fish will live the longest in the aquarium?

Most people know that dogs live from 8 to 12 years old, cats live about 12-14 years. But how many live aquarium fish? When amateurs dare to get fish in their home, they rarely get interested in the issue of life expectancy, and then they wonder why the pet suddenly died. Although the life expectancy of wild fish is not fully investigated, what to speak about aquarium species. With proper care, many pets live from 2 to 20 years or more, depending on size, personal stamina and feeding. Even a fish with a short life expectancy will live longer than expected, if you create a "paradise" in the aquarium.

Freshwater species

Many freshwater fish species live from 1 to 6 years. The most popular small fish, characterized by a short lifespan: guppies, swordtails, mollies, iris, catfish corridor, some cichlids, rasbora, carnegiella, tiger barbs. There are also several species of fish that live more than 5-6 years with proper care and feeding. Among them: kissing gourami, zebrafish zebra, beta, fish Jack Dempsey.


If you are looking for fish with a lifespan of 10 years or more, then it is better to purchase blue neons, angelfish, Oscars or plecostomus. The famous long-lived aquarium is a goldfish. With proper feeding, clean and healthy aquatic environment, goldfish species live up to 15 years. The oldest aquarium goldfish has lived to 30 years, it is the only officially registered case.

Look at the 25 year old goldfish.

Species living in salt water

How many live aquarium fish who prefer salt water? Despite the narrow distribution in domestic nurseries and the complexity of the content, yet some lovers are trying to provide them with all possible living conditions. A balanced level of salt in the water, proper nutrition and an appropriate volume of the aquarium can prolong life. Most marine fish live in public aquariums, where they live in the best conditions. Many marine fish suffer from diseases at the beginning of life due to poor care.


Some species that live in brackish water live from 2 to 4 years. Among them: butterfly fish, mandarin duck, Moorish idol, bullheads, sea dogs, Napoleon, monodactylus (swallow fish), triggerfish, surgeon fish, degu. Most small tropical seahorses live in aquariums for 3-4 years. Larger seahorses can live longer, but are rarely available for a home aquarium.

More hardy marine species can live in captivity for 10 years or more: they are lion fish, clown fish, eels and sea bass. There are many varieties of angelfish that live long in brackish water. Sea fish angels can live more than 20 years, and grow to impressive size.

Fish families, life expectancy in years of some representatives

Large aquarium fish live longer than small ones, some are able to outlast a person. Since fish are cold-blooded animals, the temperature of the body corresponds to the temperature of the water. As it rises, processes in the body are accelerated, as a result of which the body wears out and ages. It also shortens the life of pets improper feeding or overfeeding. Aquarium cichlids have a sensitive gastrointestinal tract, and in case of an irregular dose or the addition of live larvae, they can easily get sick. Clean water is also important - scaleless species are sensitive to impurities of chlorine, nitrite, nitrate and organic matter. Fishes of the genus Polypterus and Labyrinth need access to atmospheric oxygen.

Representatives of the Haracin family live an average of 5-10 years: tetras, congos, neons, minors, piranhas, metinnis, pacus.

The life span of the Karpovs is from 5 to 30 years: danios, morulius, rasbor, barbs, labo, cardinals (5-10); goldfish, shark balls (10-30).

Cichlids live from 5 to 18 years: discus, frontozy, African and South American cichlids, nichbochromis, astronotus, severum, labidochromis, apistogram.

The representatives of the family Karpazubye, viviparous fishes live for 3-15 years: swordtails, Petsilia, Molly, Guppy and others.

Members of the family of the Viunovye live 10-15 years: the ordinary loach, combat.

Fish species of the Som family live from 5 to 15: glass catfish, otozinclus, plexostomus, pimelodus, synodontis, mystus, banjo, sturizoma, tarakatum.

Other aquarium fish, representatives of different families: apheosimions (1 year); tetraodons, sprinkler fish, clin-belly, iris, leporinus (5); panaki (10).

How many years live, the life of the aquarium fish

Aquarium fish - gentle creatures that require constant attention and care. Currently, there are a huge number of their diverse species, each of which has its own specifics. The rejection of this specificity by an aquarist leads to disease and death of the fish. Although, even when creating ideal conditions for them, they are not immortal and eventually die simply from old age.

The period of life of aquarium fish released by nature, depending on the family and species, each has its own. So, for example, among the Kharacin (Minor - 6 years, Neon - 4 years, Tetras - 5.5 years, Piranhas - 10 years, Metinnis - 10 years), the average lifespan is seven years. Carp (Cardinal - 4 years, Goldfish - 15 years, Barbus - 7.5 years, Rasbora - 7.5 years, Danio - 6 years), on average, can please an aquarist with his presence for eight years.

The most diverse in color and shape of the fish belonging to the cichl family (Apistogram - 4 years, Discus - 14 years, Tsykhlozom mezanauta - 10 years, Tsikhlozom meeka - 12.5 years, Scalaria - 10 years, Severum - 14 years) live on average 11 years . Viviparous tooth-like ones - such as Molineses, Petsilia, Guppy, and the Swordsman, live, on average, less than others - 3.5 years. Among catfish (catfish glass - up to 8 years, speckled - 9 years, Tarakatum up to 10 years), the average life expectancy is 8 years. The life of labyrinths (Gourami, Lelius, Petushki) is about 5 years.

It is believed that in old age fish have the greatest completeness of their color and beauty. The actions of an aquarist largely determine how many years aquarium fish has lived. Seasoned aquarists are striving to prolong the lives of their pets, taking into account such factors that affect their life expectancy as stable conditions, regular feeding, and the absence of predators.

The most advanced and successful aquarists are confident that under optimal conditions of maintenance the lifespan of fish increases.

However, not everything is so simple and straightforward. You should always look for the "golden mean", as the aquarium contains, as a rule, more than one type of inhabitants, which makes such investigations extremely difficult.

An aquarist should independently, in his own experience, having traveled a long way, consisting of trial and error, select the very conditions that will be optimal for all of his beloved pets. The main thing in aquarism is constant self-education, which will help to achieve success.

COMPATIBILITY OF GOLDEN FISHES



COMPATIBILITY OF GOLDEN FISHES
WITH OTHER FISH SPECIES

Compatibility issue Goldfish (Carassius) on the one hand, it is rather simple, but on the other 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 start with the fact that ALL BREEDS OF GOLDEN FISHES were obtained as a result of millennial selection. Therefore, the Voilehvost, Orandy, Telescopes, Shubunkins and others are artificially bred breeds, which, in fact, were obtained from one ancestor - 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 body of water - PROHIBITED!

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 observing all aquarium compatibility rules, you can get a negative result. 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, Apistograms, Parrots, Tsikhlazymy: 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, ternistus, pulcher, lanterns, glass tetras, congo 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, macrapods dr.

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: barbusses, 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 such a topic as 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.

How long can a goldfish live?

Unknown

It depends on the volume of the aquarium and its equipment. goldfish need a volume of 20 liters per individual with good filtration and aeration, regular water changes. when overpopulated, the fish are inhibited, which significantly reduces their lifespan. they live about 5 years.

Gayane

Goldfish (lat. Carassius auratus)
More than a thousand years ago, the first color varieties of Chinese goldfish appeared in China. From them the goldfish with all its varieties leads its pedigree. Aquarium for goldfish should be spacious, with a large pebble or gravel. Beautiful fish "in the soul" remained crucian and, like crucians, dig in the ground, stir up water and dig out plants. It is necessary to have powerful filters in an aquarium and plant plants with a strong root system or in pots. Content [show]
[edit]
Conditions in the aquarium
Water temperature can vary from 15 to 25 ° C for long-bodied species, and from 22 to 28 ° C for short-bodied. The chemical composition is not important. The aquarium is populated with adult fish at the rate of 2 dm² of bottom area per one long-bodied fish, or 1.5 per short-length fish. Veil forms contain peaceful neighbors, not prone to biting fins. When keeping big-eyed fish there should not be sharp stones, shells and other objects about which you can get hurt. They are weak-sighted and slow, do not have time to take food at the same time as nimble neighbors and starve. Goldfish are omnivores, and arthritis, earthworms, animal feed, seafood, white bread, semolina and oatmeal are suitable for feeding. You can make balls of bread and minced meat. It is good to give lettuce and nettles, otherwise the fish will begin to eat the plants. Riches and ducklings are desirable in an aquarium - fish feed them. They are voracious, but you can not overfeed. Overeating leads to inflammation of the gastrointestinal tract, obesity and infertility. They feed fish 1-2 times a day and feed for 20 minutes. The excess is immediately removed by siphon.
[edit]
Breeding
Goldfish become sexually mature after a year, but full development, maximum brightness of coloring and fin fineness have to wait from 2 to 4 years. Yes, and breed them better at this age.
During the spawning period (April - May), the males on the gill covers appear pearl tubercles the size of a poppy seed, and on the front rays of the pectoral fins the smallest notch is “saw”. Males begin to actively pursue females. At this time, they need to plant and feed a variety of fortified foods. In the calfed female, the abdomen is noticeably getting fat.
Under spawning use aquariums from 40 to 100 liters. The water level is not more than 20 cm. Water is needed fresh, settled and kept under direct sunlight or quartz for several hours. In spawning are satisfied with powerful aeration and bright lighting. At a distance of 1-2 cm from the bottom mount a large plastic mesh, and in one of the corners put a large bundle of yarn or nylon wool. After planting in spawning plants, the temperature is gradually increased by 2-4 ° C.
For full fertilization of eggs and guaranteed spawning for one female, 2-3 males are taken. You can simultaneously arrange and group spawning for the flocks of fish. The label lasts from two to five hours. During this time, the female manages to sweep 2-3 thousand eggs. Eggs are glued to a washcloth and fall to the bottom under the net, where manufacturers cannot eat them. After spawning, the parents are immediately removed. At 25 ° C, the incubation period lasts 4 days. At this time it is necessary to remove dead and whitened eggs. They are covered with fungus saprolengia, which can spread to the living.
Starter feed for fry - Artemia, micro-worm or "live dust". You can apply and feed. At the age of one month, nonstandard fry are already visible, with deviations from the breed, as aquarists say, "frosting". You need to sort. In the future, sorting has to be repeated, since even in good producers all offspring are rarely without deviation from the breed standard. It should be borne in mind that many colored forms are completely colored only by the year, and their fry remains gray for a long time. Long-bodied breeds of goldfish live up to 30 years. Short-bodied - up to 12, and by the age of 8 they lose the ability to reproduce.

I want to make 1-2 goldfish in the aquarium-glass. Do they need some special equipment? How much do they live, how to care?

Doctor

with good content live at least 10 years. long-bodied, such as a comet, 20-25 years.
small feeds a couple of times a day, morning and evening. adults once. once a week, do not feed, making them fasting day.
water change a third of the volume, fresh from the tap to defend the day 2-3. if there is a filter, then make the water of the desired temperature (should be the same as in the aquarium), run through the filter and pour it into the aquarium.
aquarium 10-15l for one gold. 20-25 on such as a comet.
without oxygen, they will live you a day or two at most. powerful filtration and aeration is obligatory, gold strongly pollutes water with waste. heating is not needed, for them the ideal temperature is between 23-26.
round aquarium or in the form of a glass I do not advise - they are terribly inconvenient. with a convex front wall distort the view. Ideally, the usual rectangular.
In general, it is not so easy to maintain. the main thing is to monitor the condition of the water. in bad conditions the fish will get sick and die. if you want gold to grow large and healthy - you need a volume of 100-150l for 6-8 fish.

Ira Shupegin

you need a filter, oxygen and everything they live for about a year and a half ... you need to clean the aquarian and keep it clean and free of diseases, before planting a new fish, it should swim for a day in quarantine (water with potassium permanganate)
