How fish breed in an aquarium - a fascinating underwater world in our house

The aquarium is often the main decoration of any home. Fish, as its main inhabitants, can turn any indoor pond into a colorful underwater world, bringing joy and comfort to its owners.

Many aquarists breeding aquarium fish are considered one of the most exciting activities. It seems that it can be easier: they bought an aquarium, launched several different individuals into it - and you can safely expect new “guests”. But in this matter there are many nuances.

The variety of aquarium fish and their breeding

First you need to decide how many fish to run in the aquarium and what size they will be. After the most interesting begins: in order for the underwater tenants to be comfortable and not crowded in the aquarium, it is necessary to correctly determine its volume, take into account how different individuals can live with each other so that they do not eat each other.

An important role is played by the choice of decorative elements that make the shelter cozy, and the aquarium is beautiful and attractive. In the process of breeding various species in artificially created conditions, you can follow their interesting life. For example, how fish breed or how they feed, how they behave in different situations.

Types of aquarium fish are very diverse. Residents of freshwater aquariums are primarily divided into cold and warm water.

It is difficult to keep cold-water species in aquariums, as they constantly suffer from lack of oxygen. In warm water it dissolves much less than in cold, and in our rooms it usually has a rather high temperature.

Most aquariums contain mostly warm-water exotic individuals living in nature in fresh, sometimes brackish waters of the tropics and subtropics. These representatives are distinguished by small size, bright color and the ability to live at a constant temperature not lower than 20 degrees.

Not all types of fish can exist in the same water layers. For example, catfish live on the bottom, and in medium waters, viviparous Gupik. There are also those who inhabit only the upper layers. Such settlement in tiers depends on their demands for oxygen, which is greater at the surface of the reservoir.

In recent years, marine aquariums have also become popular, where coral reefs and some other inhabitants of warm seas live.

Breeding fish

For aquarium lovers, the question of how to
breed fish?

Basically, all the way the same - laying eggs. Some species toss eggs deep in the water: the eggs fall on plants or soil. Others prefer to spawn in different layers of water or in thickets of plants. Their eggs are often attached to the stems and leaves. Still others, for example, cichlids, lay their eggs on the rocks.

There are fish that make a nest for spawning in the sand, under stones, under plants or in their roots. Interesting representatives of some genera, which, jumping out of the water, put the eggs on the plants outside. The labyrinth species build nests from air bubbles on the water surface, and some species use small pieces of plants for this.

Most tropical aquarium inhabitants are prone to breeding throughout the year, as their habitats contribute to this. And many northern individuals and separate groups of goldfish spawn only in autumn, summer and spring.

In fact, there are no particular differences in how fish breed in a natural and artificially created environment. It is only necessary to note that the creation in the aquarium of a favorable environment for spawning can be an incentive for reproduction. They can serve as a decorative pot, a large stone, or some plant.

Many species make a marriage ritual before spawning, in the form of games. Watch at this time for representatives of the water element is a great pleasure.

Fans of aquarism do not always have sufficient knowledge and skills in this area. In fact, all breeding secrets are publicly available and many of them are contained in the specialized literature, which describes in detail how fish breed, their many species, ways of care, food, and much more.

Create a decorative aquarium, which can be a highlight in the decoration of an apartment or office, to give the room beauty and originality - everybody can do. The main thing is to have a great desire for this!

Creating an ecosystem in your aquarium that is as close as possible to its natural habitat, you can induce fish to spawn. It is not easy to breed fish, but it is very exciting and even profitable.

The question "opened a pet shop. Business is not going. What to do?" - 2 answers

It is easy enough to breed some species of viviparous fish. It is much more difficult to wait for the spawning of fish that spawn, and get a brood of fry from eggs. Very many species of aquarium fish lay eggs to get offspring. Fish can scatter eggs from algae, on the ground or stones, bury it in silt or build foam nests and store eggs in them. Fish that take care of their offspring belong to the group of "parental short ones". Among them are fish that are in the mouth of their fry.

Easy to breed fish


Macropods. Very simple in the care and breeding fish. This is the first breed that began to contain and propagate in the aquarium, which speaks of its undemanding and extreme adaptability. For breeding, the pair is separated in the spawning area, volume 5-10l, which is abundantly planted with plants. The temperature of the water is raised by just one degree. A couple is fed only live food. Soon the male begins to build a nest of bubbles and algae on the surface of the water. When the female spawns, the male lays it in the nest. Then the female and the male are removed for security purposes. Two days later, fry appear from the eggs.
Speckled catfish. An interesting, peaceful and unpretentious breed of aquarium fish - speckled catfish or speckled corridor. They can be propagated in the general aquarium, but it is better to deposit them in a special breeding ground with clean aerated water, with a temperature of 18-20 ° C. For spawning take one female and two - three males. Individuals are fed calories. Spawning place in a darkened and quiet place. The next morning, the female sticks fertilized eggs to the stones and the walls of the aquarium. Parents must be immediately deposited. Eggs develop independently, in 7-10 days fry hatch from them.

Spawning habits


Angelfish. Like all members of the cichlid family, scalarians are demanding on the purity and temperature of aquarium water. Given their complex body shape and considerable size, aquariums should be large volumes. The same applies to the spawning grounds. Before spawning, the temperature of the water is raised to 30 ° С, distillate is added. As a spawning substrate, a piece of ceramic tile or artificial leaves is placed in the aquarium. From the school of fish, the pair, ready to spawn, are separated, independently choosing each other. The pair is transplanted to the spawning area, fed with live food, but without overfeeding. Two days later, the female lays her calf, crawling on her belly. The male, following her, fertilizes the spawn. For two days, a couple vents the eggs with fins and eats unfertilized eggs. Then the substrate with caviar must be transferred to the nursery aquarium. In this case, adults are not touched, they do not tolerate frequent transplantation. After 6-8 days fry appear. At first, larvae hatch from the eggs, which cannot be fed, and only when the small fish begin to swim independently, they are called fry, and they can already be fed.
Neon. Reproduction of blue neon is hard work, and even experienced aquarists sometimes cannot take out young neon of red neon. For the spawning grounds choose a container made of whole glass, disinfect it, put the substrate of javanese moss or nylon mudroot at the bottom, pour distilled water. Be sure to use an aerator. The couple is seated separately at a low temperature of 22 ° C and richly fed. The spawning grounds are shaded with paper from all sides, they heat water up to 25-26 ° С. Stiffness should be 6.0 pH. Run a couple. After spawning, the roe is deposited under the substrate, and the fish are deposited, and the substrate is carefully removed. Fry hatch on the fifth day. And growing them is an even more complicated procedure.
Also, caviar is deposited by such common types of aquarium fish as cockerels, barbs, danios, antsistrusy, gourami and many others.

How do fish mate at home

Probably, it is difficult to disagree with the fact that the microclimate that reigns inside the aquarium largely depends on the reproduction of fish. That is why this process should be approached with all responsibility and seriousness. And first of all it is necessary to understand the sexual structure of the fish, and what types they are.

Sex structure

In order to understand how the pairing takes place in fish, we’ll dwell in detail on certain nuances that are directly related to their reproductive system. So, it is worth noting that almost 80% of all fish are dioecious. But there are also such species, where you can see the transformation of a female into a male.

As for the male genital organs, they are represented by a paired number of testes, from which ducts begin, culminating in a hole that performs sexual functions. When breeding time comes, a large number of sperm cells accumulate in the ducts. At the same time, in the female's genitals, represented by the paired number of ovaries and ending with the external duct, the eggs begin to ripen. As a rule, their number is directly influenced by both the type of fish, its size and even the years that have passed.

Important! The older the fish, the greater the number of eggs it can bear.

Types of fish

As mentioned above, mating in fish is a rather important process. But it should be emphasized that its success depends a lot on what fish inhabit the aquarium. So, emit viviparous and stray. Consider each view separately.

Viviparous

As a rule, this type of fish is very simple both in keeping and feeding, which explains their excellent adaptability to any aquatic environment. The very process of fertilization of the eggs occurs in their in utero, from which the name of the species actually came, which allows you to give birth to live fry who can eat on their own.

If we talk about creating comfortable conditions for spawning, then there should be noted the presence of a large space, the exclusion of the neighborhood of other inhabitants of the aquarium and maintaining the water temperature within 20-24 degrees. In addition, special attention should be paid to some of the nuances associated with the birth of fry. So they include:

  1. The minimum time period for caviar development is 30-50 days.
  2. The appearance of a dark spot, which is also called the spot of pregnancy, near the female's anal fin
  3. Changing the shape of the female's abdomen to a rectangular 3 days before the appearance of newborns.
  4. Newborn fish consumption of small cyclops, daphnia and juvenile Artemia

It is also recommended to run the fish in a separate vessel a couple of days before an important event for successful breeding of this type of fish, and to exclude possible complications during the birth procedure. These types of fish include: guppies, swordtails, formosis. In more detail with how reproduction occurs in this species of fish can be found in the video below.

Calving

As for this species, the process of carrying eggs occurs in them in different ways, which, undoubtedly, must be taken into account when breeding them. That is why it is so important to know what these fish can do with eggs. So, they can:

  1. To postpone them both among algae and stones, absolutely not caring about the future of the newborn
  2. Keep them in your mouth, thereby minimizing possible dangerous situations and increasing the chance of successful reproduction.
  3. Attach the eggs to your skin.

It is also worth remembering that before spawning this species of fish is recommended to be moved to a special container - spawning, in which not only the water temperature is increased, but also the light day. In most cases, the duration of breeding these fish can leave as 12 hours, and up to 50 days. It is during this period that the larvae of the laid eggs roach out.

Then, after a few days, the larvae transform into fry, which can independently feed on living dust, infusoria and rotifers. Carry fishes: gourami, catfish, barbs, an angelfish.

And in more detail how reproduction of such fish occurs, as well as the transformation of larvae into fry, can be seen in the video below.

How to stimulate reproduction?

In order to slightly increase the activity of fish for breeding, it is recommended to create the most approximate conditions of their native environment. So, for this you need:

  1. Abundantly feed aquatic adherents with live food 14 days before spawning
  2. Regularly update and enrich the water in the aquarium with oxygen
  3. To increase the temperature indicator of water in the tank by 1-2 degrees.

In addition, we should not forget about the additional comfortable care for females and newborn fry. And in order to learn how to do this, we recommend watching this video:

Neon fish care breeding description photo compatibility.

Neon fish: care

Neon pet aquariums do not differ in the complexity of care, and to overcome this simple science by the forces of the most unsophisticated aquarist. The most comfortable temperature for fish is from 18 to 23 ° C. A higher temperature indicator of aquarium water provokes accelerated aging of the pet's body, which may cause it to die without producing offspring.

The diet of neons should be varied, with a partial entry of dry live food and:

  • bloodworm;
  • a pipemaker;
  • small varieties of daphnia;
  • finished dry food;
  • semolina;
  • gruel, consisting of lettuce leaves, duckweed and spinach leaves.

It should be borne in mind that fish obesity inhibits their reproduction, and therefore, feeding should not be frequent. It is enough once a day with one fasting day a week.

Neon fish: content

Moving neons are very shy, which causes them to keep a flock, and this gives a decorative aquarium. A thirty-liter tank with abundant vegetation is quite suitable for neon housing. If the reservoir is aerated, then 1.5 liters of volume is enough for one individual; without air blowing, one pet should have at least 3 liters of aquarium volume.

Neons

Planting aquatic plants optimally placed in the back, as well as the side walls of the tank. However, you need to know that free space for movement of neons is also necessary.

Neon multiplication

Neon reach sexual maturity by eight months and retain the ability to spawn up to 4-5 years, of course, provided they are kept in conditions that are optimal for them. . Feed at this time should be strenuously and varied, be sure to include in the diet of live food. For dilution of neons, prepare a one-piece glass container with a volume of 10-20 liters.

Disinfect it and fill it with distilled water. Add to the same 200 ml of water from the aquarium, which contains neons. At the bottom of the spawn, put a bunch of Javanese moss (if you are 100% sure that there are no snails on it) or a nylon washcloth.

The main thing in the breeding of neons - to properly prepare the water. Neon spawn can be put off in any water (even in the general aquarium), but its fertilization is possible only in soft water (up to 3 °). Optimally, the stiffness is about 1 °. Neons prefer to spawn in slightly acidic water (pH 5.5-6). You can acidify it with folk remedies - for example, a decoction of alder cones, peat decoction, or you can use special preparations (there is plenty of them now available for sale).

Blow-up in spawning do not very strong, raise the temperature to 25-26 and you can run the manufacturers. Shade aquarium for breeding, leave only one corner dimly lit to see spawning results. In the morning everything should be done. The bulk of the roe should be on and under the substrate. It is necessary to plant the producers back into the general aquarium, and shake the eggs gently from the substrate to the bottom.

The water level in spawning caviar is reduced to 7-10 cm and add antifungal medication (for example, methylene blue or General Tonic). At a temperature of 25, caviar develops 36-48 hours. The fry first hang on the glass, then begin to swim. It is very difficult to feed juvenile neons. At an early age, the fry of neons see very poorly, they have only developed a focus on light - phototaxis. This and need to use for feeding. Весь аквариум необходимо затемнить, оставив лишь в одном углу луч света.

В освещенном месте будут скапливаться инфузории, необходимые для питания мальков. При таком освещении мальки неонов не останутся голодными, они, попадая в тучку инфузорий, начинают активно питаться. Это дает возможность сохранить всю молодь. Gradually, the fry are transferred to feeding on the nauplii of artemia and rotifers, and later on to small cyclops. Gradually, it is necessary to increase the hardness of the water in the spawn with fry, adding a small portion of water from the common aquarium every day.

NEONS

Neon aquarium fish

The aquarium fish neon blue or ordinary (lat. Paracheirodon innesi) has long been known and very popular. His appearance in 1930, he created a sensation and did not lose popular until our days. A flock of blue neons in an aquarium creates a fascinating look that can not leave indifferent. Perhaps, beauty with neon, can not argue any other fish from tetr, nor similar black neon, nor cardinal, nor erythrosonus. And besides beauty, nature gave neons a more peaceful disposition and high adaptability, that is, he did not need any special care. These factors made him so popular.

This small tetra is an active schooling fish. They feel most comfortable in a flock of 6 individuals, it is in it that the brightest colors are revealed. Neons are very peaceful and desirable inhabitants of common aquariums, but they need to be maintained only with medium-sized and equally peaceful fish. Small size and peaceful disposition, bad helpers against predatory fish!

Best of all, blue neons look in densely planted aquariums with dark soil. You can also add snags to the aquarium to create the look most similar to the one in which they live in nature. The water should be soft, slightly acidic, fresh and clean. Neons live about 3-4 years under good conditions in the aquarium.

In the right conditions and with good care, aquarium neon fish are fairly disease resistant. But, nevertheless, like all fish, they can get sick, even there is a disease of aquarium fish, called neon disease or plytiphorosis. It is expressed in blanching the color of the fish and further death, because, unfortunately, it is not treated.

NEON AQUARIUM FISHES

Habitat in nature

Neon ordinary was first described by Gehry in 1927. They live in South America, home to the Paraguay, Rio Takuari, and Brazil basins.

And to nature, blue neons prefer to inhabit the slow tributaries of large rivers. These are rivers of dark water, flowing through dense jungle, so that the sunlight in the water falls very little. They live in flocks, live in the middle layers of the water and feed on various insects.

At the moment, neons are very widely diluted for commercial purposes and are practically not caught in nature.

Description

This is a small and slim fish. Blue aquarium fish neoWe grow up to 4 cm in length and they live about 3-4 years. As a rule, you do not notice their death, just a flock of year after year less and less.

Neon highlights first of all the bright blue stripe going through the whole body, which makes it very noticeable. And by contrast to it, there is a bright red stripe, which starts from the middle of the body and goes to the tail, slightly approaching it. What can I say? Easier to see.

Compatibility

By themselves, blue neons are a wonderful and peaceful fish. Never touch anyone, peaceful, get along with any peaceful fish. But here they can fall prey to other fish, especially if it is a large and predatory fish, such as a gray sword or a green tetradon. Can be contained with a large, but not a predatory fish, for example, with scalars. And mollies. With what fish do neons get along? With guppies, patsils, cardinals, swordtails, iris, barbs and tetras.

Neons

Gender differences

Distinguishing the male neon from the female is quite simple, even though sex differences are not very pronounced. The fact is that females are noticeably fuller, especially in the pack, where males with their flat tummies look thin. Unfortunately, this is manifested only in adult fish, but since you need to buy a flock of neons, couples will still be there.

Feeding

What to feed the neon? Simply feed, they are unpretentious and eat all kinds of food - live, frozen, artificial. It is important that the feed was medium-sized, as they have a rather small mouth. Favorite food for them will be bloodworms and tubers. It is important that feeding be as diverse as possible, this is how you will create conditions for health, growth, bright neon color.

Swordtails: reproduction and maintenance. Aquarium fish swordtails

In every home where there is a child, sooner or later, talking about pets begins. The kid asks the parents several times a day for the bird, the dog, the kitten ... He wants to take care of and watch someone, feed the pet, play with him and take him for a walk, show off his new friend to his comrades. But what to do if the apartment is too small for a dog, the papa is allergic to the cat's fur, and the mother simply does not tolerate the piercing sounds made by the parrot?

Fishes

Great exit - get an aquarium! Hassle with fish at least, and the whole family will receive the aesthetic pleasure to the maximum! In addition, these bright tropical creatures can be admired endlessly. Such contemplation of the home underwater world calms, gives composure and a beneficial effect on the psyche.

Plus, the aquarium will bring a juicy touch to the room's décor, and your child will be looked after by its inhabitants, thus getting used to discipline and responsibility. Moreover, a modern "house" for fish can look like anything! You can easily choose an aquarium so that it harmoniously blends into the overall style of the nursery. Be sure to take the baby with you to the pet store, let him, as an adult, help you choose a tank of the desired shape and size, will find residents for it. In addition to fish, you can buy unhurried snails, a variety of algae, as well as all sorts of paraphernalia - decorative locks and elegantly curled shells. As for the choice of pets themselves, it is better to start with unpretentious species of fish, such as guppies, mollies, danios, barbs, neons ...

Swordtails

For more effeminate scalars, funny shrimps and slow telescopes, if you want, return later. Explain to the child that you first need to learn how to handle simpler fish. Naturally, in any case, it is necessary to consult the seller. He will make sure that predatory and peaceful fish are not in the same “house”; advise food, soil, jewelry, a net; will tell you which compressors, filters and lighting devices are the most convenient to use.

Surely in the list of proposed inhabitants it will be the swordfish fish.

These undemanding small fishes (most often bright red or black in color) with beautiful sharp tails are ideal as the first pets for your kid. Firstly, they do not need special conditions of detention, secondly, they easily get along with other types of fish, and thirdly, they are viviparous. Reproduction of swordtails in an aquarium, it can be said, happens almost by itself. And imagine how much joy the child will have when he sees the first fry that will grow before his eyes!

Reproduction of aquarium fish

So, the choice is made - the swordmen. Their reproduction is a fairly simple process. Fish reach sexual maturity at the age of 6-8 months. The female swordsman is larger, the male is smaller, but only he has the famous long tail in the form of a sword, for which, in fact, this species got its name. Therefore, it is not difficult to distinguish them and understand how many “boys” and “girls” are in the aquarium. It is better to have more females than males. There is one more detail: if there are only two males, they can behave aggressively towards each other and often fight.

Therefore, let him either be alone, or four or more - then their attention is sprayed, and the aquarium swordfish fish will behave much calmer. Consider this nuance when buying them.

Tips for keeping and breeding

To get the offspring, you need to maintain a stable water temperature, make sure that the filter works well, there were areas shaded by algae where the fry can hide. Moreover, it is desirable that the plants were different - and those that are planted in the ground, and those that float on the surface (duckweed, riccia, pistis).

About once a week or as far as evaporation it is necessary to accurately add a certain amount of clean water to the aquarium. Only, God forbid, not from the tap!

At first, it should stand for at least three days, and only then this water can be used. Of course, henceforth the holy duty of the child is to feed the fish in time. Swordtails are eaten mostly with live food, such as bloodworms, pipemaker, daphnia, or cyclops. However, they do not disdain and combined types of food, and pounded oatmeal, and can pinch the algae.

Swordtail aquarium fish will not be lost, even if you decide to leave them for a week, for example, to go on a vacation to the village. They can easily find food at the bottom of the aquarium and its walls, among the pebbles and on the plants. But this does not mean that they can be left to themselves, without looking into the aquarium for 2-3 weeks.

Features of the content of fish

When biological equilibrium is established in the “fish house,” the swordtails get used to each other, their reproduction will take place without outside intervention. One fine day, the child will simply notice that one or even several females noticeably "rounded", became more pot-bellied and sluggish. Explain to him that soon there will be kids in the fish. There will be joy!

Pregnancy lasts about a month and a half, and after this time a whole flock of fry is born. They can be as much as 15-20 pieces, and much more, sometimes the number reaches as much as one hundred. These are fully formed fish, only small and translucent. They independently swim, eat, possess an instinct of self-preservation - they hide in the branches of algae, swim under decorative ornaments. However, if you want to save all the fry, at first they still need to create special conditions. So, a pregnant female shortly before birth is better to be separated from other inhabitants of the underwater world.

Important note

A small aquarium or even a regular glass liter jar, washed with baking soda, is suitable for this purpose. There you need to pour part of the separated water and part of the water from the aquarium, plant a couple of plants. It is desirable that the algae were small-leaved and of both types - ground and floating, then it will be easier for newborns to hide in them. Let the child carefully, with a special net, catch the future mother and quickly launch into the prepared temporary shelter.

After the offspring is safely born, the female needs to be returned back to the aquarium, since with its sharp teeth it can destroy unwary fry. It is better to feed newborns with cyclops and daphnia. When the fish in the bank grow up a little, they can be shared with the rest of their relatives.

Interesting feature

In fish such as swordtails, reproduction under favorable conditions - a stable water temperature, good lighting, live food - can occur every month. Fry quickly turn into mature individuals. So, already in 3-4 months, the males will acquire a sword tail, and in a couple of months, full-fledged adult swordsmen will swim in the aquarium. Fish breeding will begin on a new ... However, if pregnant females are not relocated to another tank, the law of nature, such as natural selection, will act, during which not all fry will survive, but only the most nimble and brisk.

Small conclusion

Here they are unpretentious, swordfish fish. Reproducing them, as you already understood, practically does not need any correction, and, if you give them free rein, the inhabitants of your underwater world will breed to such an extent that it will be possible to bestow fry on all their acquaintances and relatives. We wish you success in their breeding!

Propagation of the Sword in Captivity

The breeding of the Sword is one of the main issues that bother novice aquarists. However, it is easy to solve, since breeding of the swordtails is possible both in the general aquarium and in a separate spawning ground. In order for reproduction to turn out to be fast and correct at home, such moments should be taken into account:

  • Creation of proper conditions for producers;
  • Proper spawning organization;
  • Quality care for the fish.

How to create optimal conditions for reproduction?

Swordtails are viviparous fishes that produce fry ready for a full life. They become sexually mature at the age of 6-8 months, some specimens may be ready for reproduction at the age of 3 months. To reproduce succeeded, you need to pay special attention to the diet of future producers. Protein food will allow you to produce as many healthy fry as possible.

The optimal feeding base for adult males and females is live and vegetable food. A few weeks before breeding, feed the fish with daphnia, cyclops, coregetra, artemia and bloodworms. Food with spirulina, spinach and lettuce leaves, dandelion leaves, and soft cereals (rice, millet, oatmeal without salt) are suitable from vegetable food. To saturate the aquarium with algae food is not necessary so that the water is not enriched with ammonia and nitrates.

See how to breed Swordsmen.

Reproduction can stimulate the substitution of water, as well as increasing its temperature by several degrees. Provide filtration in the aquarium with an internal filter, and aeration. Pure water saturated with oxygen will stimulate the mating of fish. Once a week make a replacement of 25% of water for fresh and clean.

Swordtails, the reproduction of which will not occur in the spawning grounds, but in conditions of a general aquarium, should get used to the gradual increase in water temperature. The temperature regime should be set at 26-28 ° C, raising it for 5-7 days. The acidity of aquarium water is allowed at pH 7.0-8.0, the hardness - 10-12 dH. The number of females and males in the brood depends on the water temperature. In water with a temperature below 24 degrees there will be more females, above 25-25 degrees - males. Similar water parameters should be in spawning. In order for producers not to experience shock when moving to such a reservoir, the same parameters of the environment should be in a permanent aquarium and spawning grounds.


Preparation of fish and spawning for breeding

In order for the offspring to turn out beautiful and healthy, it is necessary to choose males and females for spawning. The age of males should be 8 months, their tail fin should stand out with a long lower ray, and gonopodia should increase in size. The female should be 8-10 months old, large in size and have a rounded abdomen, which indicates readiness for reproduction.

Fertilization of the fish swordtail intrauterine. If fertilization has occurred, part of the male spermatozoa will remain in the female's abdomen, which will fertilize the female again, without the participation of the male individual. Therefore, having gotten the Sword-bearers, you should know that these fish can produce offspring every month. In one spawning, the female sword bearer will give birth to 50-200 fry.


Why exactly this amount? The fact is that young females bring less offspring, mature ones more, and with each birth the number of fry will increase. Also, the number of calves depends on the species, the conditions of the fish. Pregnancy lasts 4-6 weeks; in the female, the belly will become round, before giving birth it will become almost square in shape. A month before giving birth you need to prepare a spawn.

As a spawning tank suitable capacity of 25-50 liters with infused tap water. It is recommended to plant small-leaved vegetation in the bottom of the tank, in which fry will be hidden. After preparing the spawning grounds, a female is fed into it, which is fed with live food. After the birth of the young, the female fish is deposited in a common aquarium so that she does not eat her brood. For delicate felling, use a net.

See how the swordtail fry are born.

Can swordtails change their gender?

Swordtails are special viviparous fishes that are capable of changing sex throughout life. This feature is due to the absence of sex chromosomes. Newborn swordtails do not have obvious sex characteristics, only at the age of 3-6 months they will be noticeable. Some fry breed at the age of 3-4 months, so they should be sorted by gender - females and males should be settled in separate containers.

During the life of the female swordtail can become a male, and vice versa. Such metamorphoses are inherent in those individuals who are trying to preserve the species in the face of the threat of extinction of the pack. In one aquarium can live 1 male and 2-3 females. With the passage of time, the male may die, and one of the females will begin to turn into a male. It forms gonopodium, lengthens the lower ray of the caudal fin. When the fish that have changed their sex from female to male reproduce, their descendants will be female.

You can adjust the sex of the fry of the future pets. If you want to breed males or females for sale, the water temperature must be raised or lowered by several degrees. Avoid early crossing of fry, they are ready for it at an early age. При скрещивании видов, может получиться красивое потомство, при скрещивании селекционных пород, произойдет вырождение.

Размножение суматранских и других барбусов

Барбусы - питомцы, которые подойдут для начинающего аквариумиста. Абсолютно неприхотливы в содержании, с миролюбивым характером. Следовательно, размножение барбусов в домашних условиях не покажется чем-то непосильным новичку. The most common in the aquarium is a Sumatran barb with an amazing striped color on a yellowish-golden body.

How to prepare for breeding

With the first experience of breeding fish, which spawn, the Sumatran barbus will not cause trouble. Such aquarium fish breed and in the general aquarium, a separate spawning - an optional condition for spawning. But first, let us tell you how it multiplies in the conditions of "eviction".

  1. If you feed the fish constantly and intensively, they will willingly start spawning;
  2. At the age of 5-9 months, the barbs become sexually mature and ready to reproduce offspring;
  3. Usually they breed in separate aquariums, where there is a calm atmosphere;
  4. The temperature of the water in the spawn should vary from 22 to 24 degrees;

Selected parents should be fed abundantly before evicting to spawning. Recall that the males of barbs mature 1-1.5 months later than the females.


Before spawning, the producers are seated in different aquariums for a month, offering them a special meal: for the male - proteinaceous (tubule, bloodworm), for the female - vegetable. The temperature of the water is understood to be 2 degrees. The differences between male and female are as follows: females are smaller than males, have a rounded belly. A "swollen" belly indicates readiness for reproduction into the world of posterity.

There are cases when the fish are not fully prepared for spawning. Sometimes several males immediately pursue one female. For breeding it is better to choose the most dense female, with a “full” belly and the most active “male suitor”, with the brightest color. If in a separate spawning ground the female pursues a male, and not vice versa, then it should be replaced with another. When the male behaves too actively, water plants can be placed in the aquarium, which will calm the male, and the female barbus will be able to hide and calm down.

What is necessary for spawning

Before spawning, the aquarium should be ready (volume 10-20 liters, do not contain soil). At its bottom it is better to lay a separator net, which will prevent the parents from eating the eggs. In addition to the mesh, Javanese moss or synthetic fiber can be an excellent substrate for the bottom.

Producers are “resettled” in spawning in the evening, raising the water temperature to 25-26 ° C. Immediately it is not recommended to feed the parents. Morning is a harbinger of beginning spawning, which will last from 2 to 3 hours. For several hours, the female barbus will bring 100-600 eggs. When the female starts to avoid the male, this is a signal that the spawning has ended.


After spawning, fish can live in their usual, common aquarium. And in the aquarium, where the young will first live, it is necessary to replace 25% of the water with fresh. To prevent the formation of fungus on the calf, methylene blue is added to the water (diluted in water until it forms a light blue color).

Eggs should not fall in direct sunlight, it is better to darken the aquarium or move it to a dark, quiet place. After 12 hours, empty, unfertilized white eggs are gently removed with a pipette.

Fry care

Fish roe develops over several days, after which the larvae appear. For 3-4 days fry appear, collecting infusoria and live dust, rotifers, artemia. They are very active, so they have to feed more often - every 3-4 hours with a regular change of water. Preferably a varied diet with the use of live food, so that the fry will produce fruitful adult fish. It is also recommended to feed a special liquid food for fry.

The first days of life aquarium lighting should be 24 hours a day. When they are 1 month old, they will resemble adult individuals.


Sumatran barbus can breed in a common aquarium, but in order to protect the eggs from being eaten by other inhabitants and by the parents themselves, it is better to create a calm and comfortable environment for their growth. In stores, young fish are sold at the age of 3 months.

How to breed goldfish

The maintenance of goldfish requires special attention from their owner. These aquatic inhabitants are distinguished by a rather whimsical character, so all additional elements for an aquarium should be selected very carefully. Reproduction of goldfish is a special process. The result of this period depends on your patience and knowledge.

The question "opened a pet shop. Business is not going. What to do?" - 2 answers

Instruction

1. There are many varieties of goldfish. In order to obtain good and “qualitative” offspring, during the spawning period, fish pairs of only one species should be deposited in a separate tank. Fry from different parents can inherit completely unpredictable traits, with the result that it will be difficult for small fish to be attributed to a particular breed.

2. Golden fishes become capable of breeding closer to the year of life. To determine the sexual maturity of the fish can be on some external changes. In females, distinctly visible growths appear on the front fins, and the tummies are rounded. Males change their behavior and try to spend as much time as possible in the society of females. In addition, on the gills they appear bright tubercles.

3. During the transfer of goldfish for breeding in a separate aquarium should pay attention to the potential conditions of their habitat. It is desirable that the situation and the temperature of the water in it practically did not differ from the usual dwelling for the couple. Otherwise, the long-awaited spawning may linger for a long time.

4. The process of courtship in goldfish takes place in an active form. The male by all means tries to drive the female into the most secluded place. As soon as this happens, he presses the female with his body and waits for the beginning of the laying of the eggs. Fertilization occurs immediately after the release of eggs from the body of the female.

5. Within several hours the female can lay eggs several times. The male at such moments is always near his companion. During the spawning rut of the inhabitants of the aquarium is better not to disturb.

6. Please note that immediately after the process of laying the eggs of goldfish is completed, it is necessary to return them as soon as possible to the old aquarium. Otherwise, they can eat their own eggs for food.

7. Delayed eggs at first is almost impossible to notice at the bottom of the aquarium because of the transparent shell. Color begins to change after 1-2 days. Your task is to constantly inspect the aquarium. As soon as you notice the location of the eggs, immediately remove them from the water with a special net.

8. Caviar should be placed in a solution of blue methylene. This tool can be found in any pet store or pharmacy. This substance will preserve the process of life inside the eggs. Otherwise, the caviar can become infected with a fungus, and all offspring will die. Treat future fry enough for several hours.

9. Fry appear from the eggs after about 5 days. Goldfish grow quite quickly, but you have to control the temperature of the water almost constantly. The optimal environment for fry - 23-25 ​​degrees.

10. Feed the fry need special food, differing in their consistency. Food for young fish usually resembles dust. After 1-2 months, the fry will be able to eat the food, which is usually offered to adult goldfish.

note

The behavior of the male during spawning may resemble an aggressive attack. However, in this way he only tries to provoke and speed up the process of laying eggs by the female.

Helpful advice

Feed the fry need every three hours. If you see that small fish are often near the surface of the water, then do not rush to worry. Thus, they just try to get enough oxygen.
