maintenance, care, compatibility
The fish living in the aquarium require constant maintenance of a certain composition of water, and, despite the filtration and aeration carried out, there comes a time when you have to change the water in the aquarium. This is a mandatory process, which can be carried out in part or in full.
Novice aquarists wonder: how to change the water in the aquarium with fish, should it be defended? It is advisable to check the tap water for the content of harmful substances in it, and if they are present, the water should be defended for three days, and the use of special cleansing compositions is also permissible.
If you do not do this, you can simultaneously change no more than 20% of the composition of the water in the aquarium.
Replacing the full amount of established water in the aquarium, and forming a particular ecosystem, should be extremely rare, it negatively affects the fish and plants, they are difficult to get used to the new water and often die. Even making a partial replacement of water, it is worthwhile to worry about maintaining its temperature, as well as gas and salt composition.
If there is a need to completely change the water in the aquarium, you should temporarily relocate all living organisms to another tank, completely clean the aquarium, fill it with settled water, and after a few days when the biological balance is restored, return the fish and plants to their original place.
Features of the water change for the aquarium with cockerel fish
Cockerel fishes best of all feel in big aquariums, water in which not less than 27 degrees. How to change the water in the aquarium with cockerel fish?
There are no special requirements, you just need to know that this fish does not need frequent changes of water. In this case, the cock carries both soft and hard water.
Changing the cockpit water to a new one, it is necessary to add the old part, while necessarily observing the temperature regime. At the time of water replacement, the fish should be deposited in another container.
Cockerels are small aquarium fish; in captivity, their body length reaches 4-6 cm, males are a centimeter more than females. In Betta splendens (common cock), the body color is green-olive, with dark spots or stripes.
The fish mimic the environment, so the color of scales may vary. During spawning and aggression, the body becomes bright, at rest it is faded.
In the wild cockerel, the fins are short and round. Now there are many breeding forms of these fish, which differ in color scales and fins.
As a representative of the contract. Labyrinth fish, the cockerel is a double-breathing fish, can breathe like gills, and there is atmospheric air. It captures air into the labyrinth channel, where it dissolves. This is a big plus, because in aquarium with cockerels aeration is not necessary, in this case it is much easier to care for a pet in an aquarium.
They can be kept in “Spartan” conditions, although this is undesirable. Caring for them will not cause any trouble even to a novice in aquarism.
If the aquarium water temperature, acidity, purity are maintained at a normal level, the pet will live longer.
Watch the video story about the cockerel fish.
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.
In the cockerel fish, sexual dimorphism is noticeable: females are smaller in size, not so bright in color, they have short fins. Males are larger, with lush and long fins. During spawning, the umbilical cord resembling a white dot can be seen in females.
Fish become sexually mature at the age of 4 months, they can breed in another 2-4 months. Care of manufacturers implies a separate spawning.
If the female has not reproduced for a long time, her calf turns into a cyst, which can lead to death. Males that have already multiplied have fins longer.
Males live up to 3 years old, it is better not to plant old fish for spawning.
See how the spawning of cockerels.
The spawning volume is allowed 10-20 liters, with a height of water of 15 cm. Soil is optional, and floating plants are needed.
The male will provide care for the fry by building a nest of bubbles and fragments of vegetation. In the tank should be shelter for the female.
The manufacturer makes a nest, and invites a female, or several females, if you have more of them.
Stimulates reproduction increased water temperature – up to 28-30 degrees Celsius. Updating the water also gives spawning signal.
2 weeks before the process, the fish are fed with live food (moth, daphnia). Aeration in spawning is not needed – it will destroy the nest, and with it, the eggs and larvae.
First, a male is launched into the tank, and a female in a day.
Fish will spawn in a few days, if breeding does not occur in a few weeks, it is better to change the female. With extreme aggression of the male, change it to another. In the process of spawning, the male takes care of the female, helps her squeeze out her calf, pressing the body.
He immediately fertilizes the released eggs, grabs them with his mouth and takes them to the nest. When the spawning is over, the female can be moved to a common aquarium so that it does not suffer from the male.
The larvae will hatch in 2-4 days, depending on how the temperature of the water in the aquarium increases. At this time, the parent provides masonry care, picks up dropped eggs from the nest.
When the fry hatch, he will still be with them. After 4 days, the fry will swim independently; then the male can be removed.
During one spawning 200-400 eggs can emerge, but 1/3 of them survive.
In the first days of their life they are fed live dust, ciliates, egg yolk from hard boiled eggs. After a week, they can be given Artemia larvae, shredded strawberry or special food for fry.
In order to properly develop the labyrinth organ, it is possible to turn on weak aeration in their nursery and lower the water level. The labyrinth organ will be formed in a few months, but all this time, from incubation to the age of the young, the fry need to be constantly looked after.
In the cockerel fish, it is quite easy to distinguish the female and the male. The male is slender, has a bright color and long fins. The female is smaller in size, its fins are short, on the abdomen near the tail there is a small white grain, which appears at the age of 3 months.
For breeding is better to take a pair at the age of 6-8 months.
Despite the fact that spawning can occur in the general aquarium, it is still better to fish the fish. A pair of aquarium should have a length of at least 15 cm, volume 4-5 liters. They equip it like this: the ground is not laid, a dimmed lighting is installed, a couple of plants with small leaves are placed, water is poured to the level of 10-15 cm (after the mating of the male it is reduced to 5 cm), aeration is established.
Water temperature should be about 28-30 ° C. Water in advance to defend 3-4 days.
It is recommended to establish a shelter (cave) for the female, since the male can be very aggressive during this period.
The first to spawn put the male. There he builds a nest of air bubbles, sealed with his saliva, and small floating plants. After the female begins to spawn, he collects the eggs in his mouth and puts them into the nest.
Then the female chases away and takes care of the offspring himself. For better development of caviar, you can add boiled water of the same temperature.
After the appearance of the fry, the male is also removed.
Feed the fry finely chopped pipemaker and artemia. Dry flakes are undesirable, as they slow down the development. At three weeks of age, the fry are sorted to avoid eating large small ones.
The labyrinth organ in fish is finally formed at the age of one month. Then you can remove aeration.
And as soon as the fish begin to show aggression towards their neighbors, they are deposited and begin to contain as adult males.
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;
- delta tail;
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 optimum water temperature is 24-28 ° C, however, the rooster is fairly well tolerated to lower it to 18 ° C. It should be remembered that a long stay in a too cold aquarium is fraught with diseases.
The control is carried out by means of a thermometer.
The quality and composition of the water cockerel undemanding. Nevertheless, it is better to adhere to such a framework: hardness 4-15, acidity 6.0-7.5.
For the prevention of disease and stress reduction, it is recommended to use a special salt (half a teaspoon per three liters of water).
A prerequisite is regular water changes. In large aquariums it is held once every two weeks, and in small – once every three days.
From the bottom it is necessary to remove all remnants of food.
For cockerels, river sand or gravel is fine. You can also use purchased painted soil.
Before being placed in an aquarium, it must be ignited or rinsed under hot water.
Rooster aquarium fish – maintenance, care and compatibility with other fish
Spawning should be carried out in a small separate aquarium (from seven liters). The height of the water column at the same time should be about 10-15 cm. Shelters are made of aquarium plants and artificial grottoes.
The cockerel (female) fish will be able to hide here from the male, which is very aggressive during this period.
Producers before spawning should be fed all sorts of live food. Bright light is not needed.
In the spawning aquarium should not do aeration – it will prevent the construction of the nest.
Sexual maturity in fighting fish occurs in three to four months. Spawning can be stimulated by a large water change. It is heated in an aquarium at 1-3 degrees.
Pre-fish “acquaint” with each other. To do this, they are placed in adjacent tanks so that they can see their neighbors.
For the male, small floating plants are added so that he can strengthen the nest. At the beginning of spawning, starting to build a “dwelling”, the male cock lets out small air bubbles, then gluing them together with his saliva. About a day after the manufacturer was launched, a future mom would sit down to him.
After the start of spawning, the male cockerel collects eggs from his mouth and carries them to the nest.
At the end of the spawn, he becomes aggressive, attacking the female. Therefore, it should be removed to another aquarium. The male breeds the offspring – he guards the nest, picks up the fallen eggs, placing them back.
After the larvae hatched, the cockerel does not allow them to spread in different directions, collecting them.
A female at a time is capable of sweeping 100-300 eggs. Under normal conditions, spawning begins in a day or two after a pair of males is placed together in an aquarium.
It happens, however, that this process is delayed for a week. After a day or three, the larvae appear in the aquarium. After all the fry appear, and this will happen in 4-6 days, the male is removed, otherwise it is able to transfer the fry spreading in different directions.
In a spawning aquarium, the rooster is usually fed with bloodworms. Feed must be rinsed beforehand.
In males fry, a labyrinth organ will appear only in a few months. To create good conditions for the young, it is necessary to establish aeration.
You can lower the water level.
The fry are fed with infusoria – “living dust”. In exceptional cases, you can give a steep egg yolk.
However, it is not worth to abuse such lure. When the young growth grows up, it is possible to transfer it to feeding by the Artemia larvae.
Next, the size of the feed is selected based on the size of the fry. You can enter shredder into the diet or specially developed industrial feed.
They live fighting fish for about three years. In the “old” age it is undesirable to use them as producers.
The cockerel fish has an oval body, elongated in length, slightly compressed on the sides. Its length is up to 5 cm in males and smaller, up to 4 cm, in females. Beauty and brightness, “fabulous” color is not equal to them.
At any turn, red, yellow, orange, pink, green colors sparkle and play, taking all sorts of shades. Especially bright color in males when clashing with each other.
During spawning, the cockerel fish is also “painted” with paint. The females are a little paler than their gentlemen, the fins of the “ladies” are short and not so luxurious.
However, breeders are working in this direction. Not long ago, females appeared in which the fins have a more elongated shape, and the color of the body is not inferior to the males.
The cockerel fish has dark stripes across or along its body. The upper fin and tail of this species have a rounded shape, the lower fin, starting from the head, comes to the tail.
Pectoral fins of cockerels have a pointed shape. It is interesting to observe the fish that are excited – the gills of the males swell, forming a bulging “collar” around the head.
The differences in the sexes of these fish are obvious. The cockerel- “boy” is more slender, it is brighter colored, its fins are much longer.
The females are usually smaller, their fins are shorter. The main difference between the “hen” and the cockerel will be the presence of a female with a small white speck near the anus, the “grains”. This formation resembles a little bit like the outward “egg”.
It becomes well visible from the age of three months.
What else do you need to know after the cockerel fish appeared in your house? Their content is not such a difficult task.
You do not need to have academic knowledge or special conditions in order to have a rooster fish. This species feels great even in a small-sized aquarium.
Some owners manage to keep one individual in the usual three-liter jar. But the two males in one “pond” do not get along. True, some owners share long aquariums with glass, settling their pets one by one in different compartments.
Many do this also because, seeing the opponent, the males begin to become brighter, more colorful, they take up belligerent poses, trying to frighten and intimidate their counterpart. Females are not so aggressive, they can be kept on several individuals simultaneously.
The cockerel fish at home can live in the aquarium at the same time as other species. It is worth, however, to avoid the neighbors with veil fins. Otherwise, the “fighters” will certainly cut them off.
It is better to settle to the cockerels of larger fish with short fins, for example, barbs.
For tropical cockerels, it is desirable to maintain the water temperature in the range from 24 to 28 degrees. It is allowed to periodically reduce it to 18 degrees. Open areas should be left on the surface of the water, without floating vegetation.
Fish need air. Special aeration of water is not needed, but it is desirable to pass water through the filter.
It is recommended to set up an aquarium so that during the day the sun falls on it for several hours. It is undesirable to put it in a draft.
Periodically thoroughly clean the reservoir. To do this, either partially or completely change the water.
The fish are pre-caught with a special net and placed in a jar. Sanitation is carried out without the use of powders.
For fish need soft water. Do not use distillate for the aquarium, as it contains not only harmful, but also useful substances.
In specialized stores sell special products to soften and purify water. Temperature should be monitored. To reduce aggressiveness and stress a little, add a little therapeutic salt (half a teaspoon per four liters).
Large aquariums need to be replaced every two weeks. In the interim, it is necessary to change it partially. Small aquariums need to be cleaned and replaced twice a week.
Be sure to remove the remaining feed from the bottom – the products of its decomposition will poison the water.
