What kind of fish can keep cockerels

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

These fish tolerate temperature drops and can feel good at a temperature of +18 and +25 degrees Celsius. But you can not allow sudden drops, because they harm the health of the pet. Like a labyrinth fish, a cockerel should live in water that corresponds to the ambient air temperature in the room: + 22-26 degrees.

Due to the fact that he knows how to breathe a labyrinth organ, aeration is not necessary – this should be taken into account by settling to him other fish that cannot live without dissolved oxygen. Replace the water should be once a week, 20% of the total volume of the tank.

Do not forget to clean the bottom of the remnants of food and dirt.

What rules should be followed so that cockerels can live peacefully in an aquarium with other fish? These rules apply to all cockerels, which can result in peaceful cohabitation with representatives of different types of fish.

  1. It is not recommended to keep with betta fish with long fins and brightly colored scales. Although the males themselves have a beautiful appearance, they are painfully perceived by “competitors”, which are external stimuli for them.
  2. You can not settle cockerels with large and predatory fish, for example, African and South American cichlids. The latter in themselves are peaceful creatures, friendly, but they do not get along with the fighting fish.
  3. Try to keep the fish in water that is suitable for everyone. You can not settle heat-loving and cold-loving species. For example, a golden fish cannot live in warm water, therefore it is incompatible with betta.
  4. Betta splendens fish can be settled with speckled catfish, tetras, gourami, swordtails, mollies. After settling the fish in the aquarium, observe their behavior. You can also keep the fish from a young age together, so they are better accustomed to each other. Fish should not be less than 5 cm in length. If the neighbor fish has died, do not hook the new fish with the rooster, otherwise it will score it.
  5. Compatibility with other fish will be successful if the betta lives in a spacious tank of 50-100 liters. There you can put a lot of decor, shelters, which will reduce to the “no” territorial claims and conflicts.

Take a look at the common cockpit aquarium.

There are such aquarium fish, the compatibility with which the betta is good, they live peacefully, with periodic fights that do not lead to death. These include gourami marble, cardinals, labo, lyalius, macrognathus, scalar.

But it should be noted that the first days of the settlement should be monitored for their reaction, in case of aggression, they are settled separately from each other.

Almost perfect compatibility of the fish Betta splendens with platies, Donaciinae, black mollies, ornatusami, nagging gourami, akantoftalmusami, befortiyami, Ancistrus, minors, ototsinklyuchami, rasbora, black tetra, Congo, botsiyami, tarakatumami, lorikariyami, gastromizonami Siamese, brocade catfish.

Cockerel fish creates incredible beauty in an aquarium, known for all its fighting qualities. He oppresses the female and similar males. This is a typical labyrinth fish that can breathe atmospheric oxygen.

The rooster has gained its popularity for its restless nature, chic appearance and the ability to live in a small pond. The Cockerel has many variants of coloring and different forms of chic fins.

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.

Your cockerel will live longer if initially purchased from a good seller. When you notice that the fish lives in quality conditions, moves well, eats, it has a beautiful appearance – it means that you can settle at home.

First of all, pay attention to the activity of the fish in the aquarium, the state of the scales and fins, its general physical condition.

Buy a young fish. The sooner she gets used to your tank, the more comfortable she will be there.

The youngsters adapt more quickly to new conditions of life. In young males, the fins are shorter than in the mature ones, and in the young the body size is several centimeters smaller.

Look at the young male Blue / Red Dragon Halfmoon Betta.

Estimate the volume and condition of the water in which the not yet purchased fish lives. If you notice a cloud, dirt, substrate of unknown origin, wait a little with the purchase.

Water should be clean, clear, slightly yellowish shade is allowed.

Look at the other fish that live in the same tank with the fish you like. Is it a little tight day? How do they move, feed, their external condition?

The Siamese cockerels are fighters, and a long settlement in a species aquarium will destroy them all. If each fish lives separately, in good conditions – this is a big plus.

Do not buy two Betta splendens at once. If you lodge newcomers in a common tank, they quickly harm each other. Buy one pet, put him in a 2-week quarantine, look at his condition.

When he gets used to the new environment, you can populate it in a pre-prepared aquarium. After a few months, you can add neighbors to it, but given the nature of the character, this is a big risk.


  1. Set up the aquarium correctly, wait until it is established biological balance. Let it be a rectangular tank with a volume of 50-100 liters. Small, round containers will not allow the fish to move, it will be uncomfortable and boring. In the spacious reservoir there is an opportunity to create an amazing aquascape that resembles a natural biotope. Use a good filter to quickly deal with biological stress.
  2. Let plants and algae be in your tank. In the most convenient for cockerels tanks there is a lot of vegetation, they are provided to ensure that there is enough oxygen in the water, and it remains clean. Buy plants from trusted vendors so that they are healthy and treated for parasites.
  3. Maintain the temperature in the aquarium. Adjust it with a water thermometer. The cockerel is a tropical fish, which is used to warm water: the temperature is 26-29 ° C. Use 50W heaters.

See how to keep a cockerel fish.

  • The life of the fish will extend the correct, balanced feeding. In the aquarium, the fish will only eat what they give it, so choose several types of feed. Live, frozen, dry, artificial – the cockerel is omnivorous. However, do not overfeed, try to give suitable, proven feed. Clean uneaten food residues in time.
  • Be attentive to your pet – watch him, play with him. Teach him new tricks to help him interact with you.

  • Do not try to provoke the fish to aggression. Sometimes you can put a mirror in the aquarium, but for a short time. Betta’s cockerel is a real fighter, so he should not be in constant rage. Do not put decorations or stones on the bottom of the tank that could damage the quality of the water. Dyes, water softeners are not always appropriate.
  • Make timely water changes and clean your aquarium. There is a perception that cockerels are very hardy fish, but this is not entirely true. Dirty water provokes illness, and even the death of a pet. Sharp changes in water parameters are also destructive for a living being.
  • Let the fish spawn. Let the roosters not have good parents, but the lack of reproduction adversely affects their health. In the female, the calf lag forms cysts with which it is difficult for her to live. Males become more lethargic and live less.

  • Make sure the lid in the aquarium is slightly open. Like labyrinth fish, cockerels must breathe more and atmospheric air. Ensure that the air and water temperatures match.
  • Many cockerels are sold in pet stores, where they are settled in small glass jars. Is it right to keep a fish in such conditions? Of course, this is undesirable.

    Despite the endurance of the fish, the aquariums for the males should be spacious enough for free movement. These fish will show their color as brightly as possible, they will stretch their fins if they live in a comfortable environment. It is important that your cockerel fish could easily turn around in the tank, without restricting themselves in their movements.

    Moreover, in the close capacity it is impossible to place the plants, decorations, filter.


    Improper settlement leads to diseases of the pet, and other negative consequences. Sometimes in the banks where the roosters were kept there could be drugs (methylene blue), there was no heating at all.

    In general, the fish simply will not survive if they limit the space. And where can they settle?

    Of course, aquarium fish can not live in a glass of water or a 1.5-liter jar. The size of the cockerels is 5-6 cm on average, so they need at least a little open space, but with space for free movement.

    If you can’t get an aquarium, you can put your pet in a 3-5-liter jar of infused water for a while. In it, oddly enough, you can put some decorations or plants.

    However, the cockerel is not a Spartan, so the best conditions for him are special aquariums for cockerels. Through the decorative tank it will be pleasant to watch the fish, there it will be able to quickly get used to it, and even produce offspring.

    Look at what aquariums are for keeping cockerels.

    An aquarium of 20 liters of a rectangular shape is probably simple in appearance, but is better suited for a fish than a glass jar. The fighting fish can calmly turn around in it, enjoy the scenery, in such a tank it is possible to maintain stable water parameters.

    It will not overheat much, maintaining a stable biobalance. In a 20-liter aquarium, it is easy to create an aquascape with decorations, plants, snags and stones.

    It can even run not one, but two fish.

    10-liter rectangular shape – if you do not have the opportunity to buy an aquarium of 20 liters, take a smaller tank. This is the minimum allowable amount for keeping one adult cock.

    However, it is much more difficult to maintain the equilibrium of the aquatic environment, it will quickly become dirty and warm.


    A circular cockpit aquarium – there is a perception that in cockpits many cockerels have finished their best years, but this is not quite so. In round tanks it is not bad to keep a pet in quarantine until she gets used to the new environment. Round containers serve as a good carrying for the fish, they can be installed small decorations, and even a filter.

    It is more difficult to clean this design – the usual scraper can not cope with algae settled on the glass. The brush will not help. It is believed that such forms of tanks badly affect the eyes of the males, they distort its appearance from an optical point of view.

    Of course, you can choose such an aquarium, but rectangular shapes are much better and more practical. They are easier to maintain.

    Look at the original idea of ​​the content of cockerels.

    For the 5-centimeter fish fit well decorated tank. You want the fish to have a full life? Then take into account the fact that the optimal aquarium for a rooster is made in production.

    Many companies offer aquariums for betta fish of a round, rectangular, even square shape. They immediately installed a lamp, lamp, decor, filter.

    Another thing – cockerels do not need constant lighting, so the lamp does not need to keep it on all the time. Light like algae, and why do you need extra trouble with cleaning?


    Try to buy a simple 20-50-liter rectangular tank with filter and lamp. Scenery, soil, shelters can be installed independently, if you know how to handle them properly. Before settling the fish, wash the glass in a tank under running water and process with baking soda, rinsing it 4 times.

    From this it follows that the best house for the cockerel fish is a classic rectangular one, where there is everything to recreate the natural biotope.

    Type of aquarium fish and compatibility of different species (table)

    Another pets for beginners – goldfish. Aquarium species of these fish are very common. If you look at the compatibility table, the line devoted to goldfish will be completely filled with red, with a few yellow areas, just like many cichlids.

    But if cichlids are aggressive, then goldfish often become victims themselves. Goldfish are large, and little things like rasbor and neon, they gradually eat.

    And the other inhabitants of the aquarium themselves can offend the slow and delicate little crowns with long fins.

    Golden fish is best to settle with their own kind, there are enough interesting varieties of this breed. It should not be forgotten that if you want to get offspring, then you cannot keep different species together.

    Who do goldfish can get along with? Aquarium species of calm catfish – the Tarakatum, fighting-clowns, corridors, peaceful tetras – Congas, terntions and calm danios will be fine.

    There are also examples of successful cohabitation of gold with neons, scalars, viviparous, but we must remember that any neighborhood of goldfish with other species may result in conflicts and death of the inhabitants of the aquarium.
