The content of cockerels in the aquarium

maintenance, care, compatibility

Cockerel content is available at home, it is possible even in a 3-liter jar. For two individuals and more will need more capacity.

Like all fish, cramped – only to the detriment. Fish will be very comfortable in a rectangular and spacious aquarium. It is not recommended to keep more than one male in the aquarium (except for the black cockerel species).

Between them there are often disputes that already speak – even between the female cockerels there were fights. The result – bodily injuries, dangling fins.

If you have nowhere to settle two males – choose a large aquarium of 50-100 liters or more. You can put a partition in it, so the territory will be divided.

Also, the fish have bursts of aggression, when there is a change of water or a female appears.

They are not easy to maintain with other types of fish – some are not averse to tear off the beautiful and long fins. The males themselves can attack peaceful fish with veil fins.

Good aquarium neighbors – danios, speckled catfish, cardinals. Compatibility with barbs is controversial, it is possible if you find a fish with D-shaped, short fins.

The males quickly get used to the neighbors, and the eviction of one of them can lead to stress.

The Betta splendens fish is a tropical species, so it is recommended to settle in aquariums with infused and warm water: water temperature 24-27 ° C, ph 6.0-8.0, hardness 5-35 dGH. Once a week it is necessary to replace 25% of water with fresh.

Aeration is optional.

They can be kept in a nano aquarium, in glass containers. But think carefully, will it be convenient for a small fish in a crush?

Indeed, in a limited space there is no possibility to plant the plants, install snags, decorations, shelters. To provide the fish with proper care, you need swimming space, safety and cleanliness.

So you can put a filter in the aquarium so that your pet does not get sick. Lighting is necessary, in the tank you can put an LB lamp of 0.4 W per 1 liter.

At night, the light is required to turn off.

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.

Caring for aquarium cockerel fish does not require deep knowledge, it is enough to follow the following recommendations. The cockerel fish feels great in a small aquarium. These are representatives of the labyrinth fish, which means that they breathe with the help of the gill labyrinth with atmospheric air.

Close the aquarium lid so that the air above the water surface warms up and your little cockerel does not catch a cold.

The aquarium can be filled with plants with large leaves, exclude those that cover the surface of the water or have sharp edges. Living plants are preferable to artificial ones; in addition, they will supply oxygen to the water in the aquarium. Take care also of shelters for fish, dark soil.

Aeration of water is not required, and you can put the filter on request. However, do not forget that the cockerel fish is inactive and care for it involves the creation of calm conditions, and the filter in a small aquarium can create excessive turbulence.

Do not place the aquarium in a draft or in direct sunlight, but the fish must have a sufficient amount of light. Clean the aquarium regularly! This should be done once a week, and if you have a small aquarium it’s better to completely change the water.

The fish is caught in a net and transplanted into a jar with a portion of the water. Then, under running water without the use of powders, they wash the aquarium and the ground and fill it with clean water of the desired temperature.

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 siamese betta splendens are very popular pets that live in an aquarium. For the first time having settled this fish, many people have a question: “How many cockerel fish live?”. The average life expectancy is 2-4 years with proper care.

If you have created proper conditions for your pet, then at home he will live as long as possible. To achieve this result, you must follow the rules for the purchase and maintenance of fish.


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.
  • 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.
