Who gets on the cockerel fish

maintenance, care, compatibility

Today cockerels (lat. Betta splendens) are popular aquarium fish.

Belong to the family Macropod, suborder Labyrinth fish. In males, the character is snooty, for which they are called “fighting fish”. They do not always tolerate settlements with other fish, it is difficult for them to live with their neighbors because of their pugnacity.

If a male cockerel is housed in one aquarium together with another cockerel, then conflicts will arise between them that will result in bodily injuries and plucked fins.

But this does not mean that they can not be settled with fish. On the contrary, a good neighborhood harmonizes life in an aquarium.

If your tank is spacious, it has created an excellent aquascap that resembles a natural biotope, there are many plants, shelters, a biological balance is established – then all inhabitants will be comfortable. An important rule – it is impossible for more than one male cock to live within the same aquarium.

They can not be called territorial fish, but it so happened that they will fight. On one male you can settle several females, so it will be comfortable.


Betta splendens females are smaller in size, their fins are shorter, their character is calmer. But females can also conflict with each other, as well as with the male. Females can be kept in one nursery by 3-4 individuals.

They are less aggressive, but their character is also unpredictable. If you notice that the betta fish show constant aggression towards their neighbors, and this leads to fatal consequences, then do not spare money for another reservoir, settling in it a restless pet.

Rules for keeping Betta splendens in a common tank

The fighting fish has got its name for the fact that the males are fighting menacing battles that can result in the death of one of them.

The male is allowed to combine with the female, but on the condition that the vessel is rather large and has a place to hide. Two males can be kept in a single tank, elongated in length using transparent partitions with openings for the movement of water.

It is better to plant tall plants near the walls in order to reduce the visibility of rivals.

In most cases the cockerel contain one. He can pick up fish of a different species, which he does not hurt.

It is impossible to place to him sedentary individuals with veil fins (guppies, voilehtails) – he will tear them off. Fast coarse fish are better suited for cohabitation, with small fins – barbs, danios.

This fish is quite unpretentious in the care. An aquarium of at least 5 liters is required for one instance. On the surface of the water should be places that are not covered by floating plants, that as the inhabitant floats to the surface to take a sip of atmospheric air.

Therefore, such a fish does not need additional aeration.

The tank should be covered with a fitted lid or glass. A fighter may jump out of it or simply catch a cold, as it often floats to the surface.

A filter for a small volume vessel will not interfere with the fighter, but is not required for maintenance.

Acceptable temperature for a cock in the aquarium is 26-30 degrees. Short-term deviations within 18-36 marks are allowed.

But if you find more than three days at an unacceptable temperature, the fish may be sick and die. Therefore, the reservoir for the cock must be equipped with a thermostat and a thermometer.

For impeccable content and to achieve a biobalance in the tank, you need to have live plants and ensure that they need lighting. Be sure to replace the water weekly in the amount of 40% of the volume.

In the rooster, the water must be clean and fresh, the individual is not demanding on the composition of the water.

The cockerel is not picky about food, can eat live and frozen food. The most favorite is the crank. It is necessary to feed him once a day, preferably not to overfeed.

The fish should eat food in 15 minutes, so the amount of feed is calculated. To maintain the health and coloring of the fish at the proper level, it is recommended to alternate between different types of feed.

For breeding, the male and female are deposited in a spawning tank – a separate vessel. The rooster is a little smaller and has a not so bright color. During spawning, the male collects eggs in the nest, which he built himself.

After spawning, the female is best removed from him, as he is extremely aggressive. The cockerel is caring for the eggs. After the larvae begin to swim, the male is best removed from the spawning.

Then you should feed the fry with a microworm and egg yolk and monitor their growth in order to avoid fights.

Observing such simple conditions, it is possible to provide comfortable living conditions for the fighting fish. She will delight the breeder with her cheerful disposition and beauty.

The betta fish or cockerel (lat. Betta splendens) is unpretentious, handsome, but can slaughter the female and other males.

It is a typical labyrinth fish, that is, it can breathe atmospheric oxygen. It was the aquarium cockerel, and even his relative, the macropod, that were among the first aquarium fish that were brought to Europe from Asia.

But long before that moment, the fighting fish were already bred in Thailand and Malaysia.

Fish gained popularity for its luxurious appearance, interesting behavior and ability to live in small aquariums. And he is easily divorced and just as easily crossed, as a result – a lot of color variations, different in everything, from the color to the shape of the fins.

The wild form of the rooster does not shine with beauty – greenish or brown, with an oblong body and short fins. He received the name of the fighting fish for the fact that the males arrange furious fights with each other, which often end with the death of one of the opponents.

Wild form and to this day used in Thailand for fighting, although not already leading up to the complete destruction of one of the fish. Despite the fact that the fish are fierce fighters, they have a peculiar behavior in a fight. If one of the males rises after the air during the battle, the second one will not touch it, but wait patiently until it returns.

Also, if two males fight, the third does not interfere with them, but waits in the wings.


But those cockerels, which you will find on sale, are far from such fighting fish as their relatives. No, their character has not changed, they will also fight. The very concept of this fish has changed, because the current breeds must bear beauty, they have gorgeous fins, so long that they are damaged even by plants, not to mention fighting.

They are kept for beauty, gorgeous colors and equally gorgeous fins, and not for fighting qualities.

With the right neighbors, they are pretty livable. But during spawning, the male is extremely aggressive, and will attack any fish. Especially fish like him (even his female) or brightly colored.

Because of this, they usually keep one for an aquarium, or they pick up fish for him that he cannot offend. A male can be kept with a female, provided that the aquarium is large enough and the female has room to hide.
Attention! The cockerel is just great for beginners and those aquarists who can not afford a large aquarium. He needs the very minimum both in volume and in nutrition.

And he is unpretentious, strong, always on sale. Due to its labyrinth apparatus, it can survive in poor water for oxygen, and in very small aquariums.

If you have been to the market, you probably have seen how these fish are often sold in tiny banks. On the one hand, it speaks about unpretentiousness in maintenance and care, but on the other hand it is a bad example. On how to choose the right aquarium for the cock you can read the link, there is nothing complicated there.

It dwells in all layers of water, but prefers the upper ones. It is very simple to keep it, for one fish, 15-20 liters will be enough, although this is a minimal amount, it still needs care. You should not keep it in a round aquarium, although it is a popular phenomenon.

It is better to have a rooster in an aquarium of 30 liters, with a heater and always covered, as they can jump out.

If you do not contain one, but other fish, you need an even more spacious aquarium, with shelters for the female, preferably with dimmed light and floating plants. From regular care, it is imperative to change the water, about 25% of the volume per week, since the accumulated decay products will primarily affect the state of the fins.

As for the filter, it does not hurt, but oxygen (aeration) is not needed, it breathes from the surface of the water.

As for water parameters, they can be very different, only temperature is crucial, since it is a tropical species. In general, it is recommended: temperature 24-29C, ph: 6.0-8.0, 5 – 35 dGH.

Cockerels are unusual, incredibly bright and exotic fish. Aquarists love them not only for their beautiful appearance, but also for their fighting character.

However, in order for these fish to please their owners for a long time, they need special care. This article contains information regarding the characteristics of the content and breeding of males in an aquarium.

The south-east of Asia is considered the birthplace of the cockerel fish. Its main habitats are warm, fresh, slow-flowing or standing bodies of water in Thailand, Vietnam, the Malay Peninsula and the islands of Indonesia.

The first mention of this unusual fish found in history in the 1800s. At that time, the people of Siam (now it is Thailand) noticed the increased aggressiveness of the males of this fish towards each other and started breeding a special breed for fighting money rates.

Cockerels were imported to Europe in 1892. The first countries to see the miracle fish were France and Germany. In the US, they came in 1910, where Frank Locke brought a new color version of cockerels.

In Russia, the history of their appearance is associated with the names of V.M. Desnitsky and V.S.

Melnikova and attributed to 1896.

The cockerels get along badly even with their own kind. Males constantly divide either territory or female. Therefore, in a small aquarium it is better to keep only a pair of males or a male with two females.

You can read about how to settle several males at the same time in one aquarium in the article “How to equip an aquarium?”.

Males of cockerel fish are absolutely incompatible with all kinds of peaceful fish, especially those with long tails and fins (for example, guppies). Females are more peaceful.

All fish can be divided into several groups of liveability with cockerels:

  • Swordsmen, petilia, black mollies, soma brocade and speckled, terntions, rasbora, ghouls nagging, minors and so on get along well;
  • there may be fights with tearing off of tails, if it is neons, guppies, cardinals, barbs, gourami spotted, marble and pearl, labo, etc .;
  • Astronotuses, piranhas, parrots, lineatuses, tetraodons, akaras, etc. do not get along at all.
  • In South Asia, cockerels were used to fight money stakes. Fights to the death of the fish, as a rule, did not lead, the case ended in shabby tails. Now such battles are prohibited.
  • The male rooster can fight to the point of exhaustion, even with its reflection in the mirror.
  • These fish are endowed with two respiratory systems: gills and a labyrinth organ.
  • Males are very interesting to show sympathy for the opposite sex: the female “fidgets” back and forth, while the male pulls out the gills and fins and wriggles with her whole body.

Do not too often iron the cockerels (although they allow), as some owners do. Scale on top has a protective layer of mucus.

If this film is inadvertently damaged, then the fish will become very vulnerable to various diseases.

Sometimes males can go to the bottom of the aquarium. If this does not last long, then do not worry – they are so relaxed. Anxiety should be beaten if such behavior is observed for a long time.

Then you need to consult a specialist and check the health of the fish.

If the fish are sick, then for their treatment there are special medicines (against fungi or parasites, antibiotics). They are best ordered at the pet store in advance.

We hope that this article was useful for those who plan to settle the fish-cockerel in their aquarium. Let the pet feel comfortable and for a long time happy with its beauty!

And according to the tradition, the video, which deals with the rules of care and maintenance of the Siamese Cockerel:

The cockerelfish (betta fish, Siamese cockerel, Betta splendens) is a species of fish that belong to the macropode family. This is a labyrinth fish that also uses atmospheric air for breathing.

The shape of the body of males is oval, it is flattened laterally and extended in length. The sizes of fish are mostly small: males are about 5 cm, and females are 4 cm.

However, there are individuals that can reach 10 cm in length. The tail and upper fins have a rounded shape, pectoral ones – pointed.

The fins of males are longer than those of females.

The males have a very interesting and varied color. They are one-, two- or multi-colored. All colors of the rainbow can be present in the coloring, as well as their shades.

Males are colored brighter than females.

The brightness of the color is affected not only by the lighting, but also by the condition of the fish: during spawning or clashes with their own kind, male males become most vivid.

The life of betta fish is approximately three years.

To date, breeders bred about 70 species of cockerels. All of them with a bright unusual color.

There are several classifications of species.

Depending on the shape of the fins and size:

  • voile tail;
  • crescent moontail;
  • crownstail
  • two-tailed;
  • round-tailed;
  • delta tail;
  • bristletail;
  • flagtail;
  • poster;
  • royal.

Depending on the color:

The cockerel fishes are considered unpretentious and easy to care for; however, some conditions should be met.

Males can be kept in small (10-15 liters), and in large aquariums. On one individual requires 3-4 liters of water.

If the aquarium is large, then it can be divided into several parts by partitions. In this case, several males can be kept in one tank at the same time without damage to their health.

Partitions are made of transparent non-toxic material with small holes for water circulation. Next to them, it is better to plant high plants in order to block fish from viewing and reduce undesirable meetings.

The males are able to jump quite high out of the water, so the top of the aquarium is equipped with a net or cover with holes for the passage of air

The cockerel is a labyrinth fish, that is, it breathes not only by the gills, but also by an additional special organ. In it, the blood is saturated with air, which the fish seizes with its mouth.

Therefore, aeration for cockerels is not very important, but it is desirable to install a filter. It may be of small capacity, as these fish do not like a strong current.

It is also important that the surface of the water is not completely overgrown with plants, so that the cockerel can rise to the surface and capture the air. Sometimes it happens that a bacterial film forms on the surface of the water. It must be removed.

This can be done with a sheet of paper, putting it to the surface of the water, and then removing it with the film.

Males in food are picky and almost omnivorous. For them you can use live, dry and frozen food.

Nevertheless, a large part of the diet should be a live feed (bloodworm, tube maker, daphnia, Cyclops, etc.). The cockerels will not refuse from rain or flatworms, snails or zooplankton.

Feed the fish 1-2 times a day. Food at one time give exactly enough to fish ate it completely in 15 minutes.

Leftovers must be removed immediately. Overfeeding is not recommended, as this can lead to fish obesity.

Well, once a week to arrange a fasting day.

One of the current issues of aquarists who are going to buy a pet Betta splendens, is how to feed the cockerel fish. Many newcomers do not know what kind of food will suit them, what should be the portions.

Malnutrition for fish is not as scary as overeating. Cockerels in the wild – omnivorous fish that prefer to catch insects from the surface of the water, there is benthos and small crustaceans.

They are not averse to plucking aquatic plants, such as Javanese moss. Traditionally they are fed with flakes and granules, which are produced by feed manufacturers.

But is this feeding right? This should be sorted out.


Let the rooster as much food as he eat in 2 minutes. Pour 4-6 pellets of food on the surface of the water, and see how quickly he can cope with them. If the fish will not take this food, or spit it out, this is not a good sign.

Either the feed did not fit, or the fish didn’t get used to it, or it got sick. If she does not eat the feed, it will sink to the bottom of the tank, where it will decompose, releasing ammonia.

This substance will cause a deterioration in the health of the fish, will create an extremely unhealthy biological environment. In case of untimely cleaning of the aquarium, improper replacement of water, it will be difficult to maintain the health of the pet.

In addition, if your rooster goes beyond eating for 2 minutes, he will get used to such feeding. It turns out, the fish will begin to overeat.

After examining the abdomen, and noticing a significant bulge on it (in the area of ​​the ventral fins), know that the fish is overweight.


  1. How often to feed Betta fish cockerel?

Young males, which are purchased in stores, need to be fed in small portions 1-2 times a day. Aquarium fish do not need to feed often, it is better to feed a little, and add food if they themselves ask.

During the spawning period, fish are fed 2 times a day, fry betta cockerels also, 2 times a day.

For these fish it is useful to arrange fasting days, skipping meals. The digestive system will have a “break” to restore, which will allow the body to get rid of accumulated toxins.

Good to miss one day of eating. You can choose Sunday, when many will be at home, doing their own thing.

On weekdays, feeding must be resumed.

Despite the fact that betta betus are omnivorous creatures, but they lead a predatory life. Remember their nickname “Siamese fighting fish”? They will attack, bite, and eat another fish that is a potential threat to them.

This means that protein food is an advantage for them.

Look at the feeding of the cockerel worms (grindal worms).

Food that should be in the diet of the fighting cockerel alternately:

  1. Flakes for fish – you can give a cockerel not very often, they are inexpensive. If the cock refuses him – continue to give him a bloodworm.
  2. Cockerel granules – specially developed feed for Betta splendens. They are sold in pet stores, and are almost a daily feed for roosters. But some pellets are too large for small fish, they drown too quickly, and are perceived as waste.
  3. Dry food – in most pet stores they are, it can be processed bloodworms and artemia. Chickens appreciate such food!


  1. Frozen products – if you have the opportunity to catch or buy from a supplier of live moths, Artemia, a pipe worker in small batches, you can freeze them yourself in the freezer. This is not such an expensive pleasure, and, importantly, they love “freezing”. It is important not to thaw and freeze the feed again, otherwise it will lose its quality and will be unsuitable.
  2. Live food – as mentioned earlier, if you have the opportunity to buy or catch live moth or artemia, they are suitable as food. But there is a remark about such a feeding: worms can reach an infection in the aquarium directly from the pond. If you have a question, why did the fish get sick – maybe the reason for the infected feed? Do not risk with it, better freeze the worms.

See how a cockerel fish eats boiled cabbage.

Summing up the above, the fighting cockerel feeding is possible with the feed of such feed:

  • Frozen or live bloodworm;
  • Frozen or live artemia;
  • Frozen or live daphnia;
  • Frozen vitreous worms (if available);
  • Frozen beef heart;
  • Frozen worms (live pipemaker often carries parasites or bacteria, in a live form it is better to avoid);
  • Frozen shrimp meat;
  • Living earthworms;
  • Live insects and their larvae;
  • Scalded lettuce, spinach.

Frozen foods should not be given at the same time as dry foods, and combine all types of feed. Dry food in large portions can cause digestive problems that can lead to more serious health problems.

Neons are small freshwater fish of the Kharatsin family. In the wild, they are very active and brisk, able to quickly hide from predators, maneuvering among thick plants. Body size reaches 3 cm in length, life expectancy depends on water temperature: from 1.5 years to 3 years.

Behavioral characteristics: due to a peaceful disposition, they can live together with each other in a flock, as well as with other species of fish. Guppies and neons, petsyli and neons, catfish and neons get along well in the same aquarium.

Such compatibility is beneficial for novice aquarists, since these types of fish will definitely not harm each other.


What else should be considered in compatibility? Males of neons are brighter in color than females, the contrast of scales depends on the species.

But one thing unites them – a horizontal strip passes through the body, which glitters with “neon” shimmering even in darkness. This feature can be attractive to predatory fish and those who do not welcome next to their more beautiful neighbors.

So settle a flock of neons of 5-7 fish and more in a spacious tank with shelters so that in case of unforeseen attacks, they can hide in time.

Neon get on well in the home pond with such aquarium fish: Pecillia (guppies, swordtails, mollies, placiums), speckled catfish, panda, tetra, danio rheo, labo, rastar, minors, gourami, iris, pulcheras, minors, hyacinths, sweaters, laboratories, rasomes, minors, gourami, iris, pulcheras, minors, marines, sweaters, minors, gourami, iris, pulcheras, minors, and fish. Consider compatibility with some fish in more detail.

See how well the scalar and neons get along in one aquarium.

Somiki corridor are excellent neighbors for small haracin ones, live together in the bottom layers of the aquarium, and collect remnants of uneaten food. The corridors are innocuous fish, also small and peaceful, they love to watch their neighbors without harming them.

Rasbory – can make an excellent company neon. Among them: the actual rasbory, boraras, microassemblies and trigonustigma, some of them belong to the family Karpovye.

Fishes of the Family Petsilievye (guppies, molly, sword-bearers, petsilia) – peacefully cohabit with haracin. Swordtails also have small body size, but males may be excessively active.

It should be borne in mind that more than two swordtail males sometimes pursue smaller neighbors, especially during the spawning period. With insufficient feeding, in the cramped, small place for swimming, the swordtails become unbearable.

So that these fish do not terrorize small neons, the aquarium should be spacious, with a sufficient number of plants and shelters.


Neons are poorly compatible with such fish:

  1. Large catfish, cichlids, barbs, astronotus, cockerels, koi carps – those who live in cool water, or have a predatory, aggressive behavior.
  2. Goldfish – they live in cool water, and are aggressive towards bright fish and their offspring.
  3. Angelfish – can live with neons only under the condition that they all grew up with the age of young animals. But neon-stranger scalar will be perceived as food. Also during the mating season, the scalar will be aggressively inclined towards everyone, including these small fish.
