How to breed fish

Every aquarist wants the fish to live in the aquarium for a long time and successfully multiply. To do this, your pets will need not only the attention of the owner, but also special conditions.

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

You will need

  • Spawning aquarium
  • Plants
  • Directory of fish species
  • Ceramic pots, tree roots, nylon filament, broadleaf plants - depending on the type of fish
  • Pipette


1. Decide what kind of fish you are going to breed. They are viviparous and sleeping off. Viviparous produce viable fry into the world, and their reproduction usually does not require special conditions. A single fertilization is enough for a female to produce fry 7-8 times. At the same time she has several dozen fry in one litter.

2. Select a pair of producers, the largest and correctly folded female and male. Pay attention to the color, it should be the brightest of all the available fish. Set the manufacturers in a separate aquarium.

3. When the fry appear, separate the parents and offspring. Fry immediately begin to feed them with small cyclops. As a feed for newborns suitable live dust. Periodically give finely grated egg yolk.

4. With the growth of fry, change their diet. Let's Cyclops larger, daphnia, bloodworm.

5. Prepare spawning fishes for spawning. Each species spawns differently. It is necessary to take into account the temperature and thickness of the water layer, its composition, oxygen content. Determine the size of the spawning area and the substrate to be put in the aquarium, the number and types of plants,

6. Plant the spawners in a spawning tank. Matrimonial games begin with the fact that the female flirts with the male. Then their roles change, the male pursues the female. Then the female lays eggs, and the male fertilizes them.

7. After fertilization, seed the growers, as many species of fish eat their eggs or fry. Remove unfertilized eggs from a spawning aquarium with a pipette, otherwise it will rot. Caviar develops from 2-3 days. There are species of fish whose development of caviar has a longer period, from 10 days to several months, and even up to six months. After that, the fry hatch from the roe.

8. Feed the fry with live dust. When they grow up and become only half the size of adult relatives, transplant them into a common aquarium.

The aquarium for the relocation of the producers of viviparous fish should be planted with leaf, peristolenic and other aquatic plants. The vegetation should be fairly dense, since adult fish often eat fry.
Fry of various viviparous fish reach sexual maturity at the age from two to ten months.

Helpful advice

Instead of separating parents and offspring, you can plant a female in a spawning basket before giving birth. The basket should have holes in which the fry can swim. -
Artemia and micromin are also suitable for feeding fry.
If you have prepared an aquarium for spawning short-fish, and they are not in a hurry to engage in love games, try changing a little the temperature or composition of the water. But the change should not be very significant, otherwise the fish may die.
Before spawning, you can hold for some time manufacturers in different aquariums. A signal to the mating games will be their connection.
Living dust is infusoria, rotifers, small cyclops, and so on. If there is no live food, you can use micromini and egg yolk, but this is at the very least.
To stimulate reproduction, feed fish with a variety of foods, especially important for a fortnight-month before spawning.

Breeding Aquarium Fish: A Beginner's Guide

Aquariums have become very popular in our time. They can be seen in homes and offices. Aquarists take fish breeding very seriously

Before proceeding to breeding, the owner of the fish must buy the required number of males and females, the best group of fish in a dozen specimens. It is often necessary to have two aquariums - separately for males and females, and another one - spawning.

This tank must be equipped with all the necessary technical equipment in advance, filled with fresh water and put in a quiet place. A couple of weeks before a person plans to start spawning, you will need to fatten the fish. For eggs that appear, an incubator is needed - usually 20 liters, without soil, sterile. When breeding fish, it is necessary to take into account that in the case of viviparous fish in the aquarium there should be a male and at least two females, as well as stock up with food for the fry - small fish hatched from the eggs should be transplanted into a sterile “teenage” aquarium, and the water in it must be particularly rich in oxygen.

Separately, it should be noted that if the short-lived fish require such serious preparations for spawning, the viviparous — guppies, swordtails, and mollies — do not require serious efforts at breeding. Such fish of popular species give birth to already formed fry. Also note that the fertilized female can produce offspring up to 6-7 times, and up to a hundred fry are born at a time.

Breeding aquarium fish of viviparous breeds begins with the selection of producers - the largest, most beautiful and bright, which are deposited in a separate aquarium with dense vegetation (where the fry can hide after birth - so as not to be eaten by adults). After the emergence of young fish of adult fish, it is better to plant it, and the fish that have appeared into the world can immediately be fed with egg yolk, small cyclops and other feeds used in breeding fish. It should be noted that the viviparous fish can not interbreed with other species due to the peculiarities of their structure. But still aquarists prefer to breed this particular type of fish.

Breeding fish

One of the most important moments in the life of any aquarium is the reproduction of fish, which must be approached responsibly and very seriously. This process will largely depend on which fish inhabit the aquarium - viviparous or sleeping ones, since they require different spawning conditions and different care in this unusual period for them.

Viviparsing aquarium fish

The viviparous fishes are unpretentious both in their content and in reproduction, which is explained by their high adaptability. Their eggs are fertilized right in the female's body itself, so that already formed fry are born, ready to eat. To create optimal conditions for the reproduction of fish of this type, you need to provide them with a large space, a separate content from other fish species and a water temperature of + 20 ... 24 ° C. All owners of aquariums need to know the peculiarities of the birth of fry in these fish:

  • the period of development of calf in the body of the female is on average from 30 to 50 days;
  • near the anal fin in viviparous fishes there is clearly a dark spot (the so-called stain of pregnancy);
  • 3 days before the birth of fry, the belly of the fish becomes rectangular;
  • the number of newborns will depend on the type of fish;
  • when breeding aquarium fish of this type, their fry will need to be provided with small cyclops, daphnia and young Artemia.

In order for breeding of such fish to be successful, and the process of “giving birth” does not cause complications, it is recommended that the female 3-4 days before this event be put into a separate container, where there are many small-leaved plants. For the breeding of aquarium fish of this type, you should acquire guppies, swordtails, beaches, and girardinus, mollies, formoses.

Fledgling aquarium fish

Aquarium fledgling fish can bear their own eggs in different ways, which must be taken into account when breeding them. They:

  • they scatter it or scatter it in the water among plants and stones, not caring what will happen next;
  • keep it in the mouth, protecting it from danger, which contributes to the successful breeding of fish;
  • they lay it in a nest of bubbles, on stones or on leaves;
  • the reproduction of aquarium fish of this type can occur even inside other organisms where they place their eggs;
  • fix it on your own skin.
  • Before spawning, fry fish are recommended to be placed in a special spawning area, where the light day is increased and the water temperature is increased. As a rule, breeding aquarium fish of this type can take from 12 hours to several months - during such an incubation time the larvae hatch from the eggs. Only a few days later the larvae turn into full-fledged fry, which need to be provided with good nutrition. Those who are engaged in breeding fish laying eggs, know that the fry in the first weeks of life should be fed with infusoria, rotifers, living dust, Artemia. Barbusses, gourami, scalar, catfish, macropods - these are the fish, whose reproduction takes place with the help of caviar.

    Stimulation of breeding aquarium fish

    In order for the reproduction of fish in the aquarium to occur more actively, it is necessary to maximally approximate the conditions of detention to the natural, natural. You can stimulate in the following ways:

    • provide the fish with abundant live food for 2 weeks before spawning;
    • breeding fish assumes the presence of fresh, oxygen-enriched water in an aquarium;
    • increase the temperature in the aquarium by 2-3 ° C: those who are engaged in breeding aquarium fish know that this contributes to the maturation of their genital products.
    • For successful breeding of aquarium fish, additional care is needed for females during the breeding season and newly born fry.

Reproduction and breeding of goldfish

Reproduction and breeding of goldfish

in aquarium

Goldfish is one of the most ancient aquarium fish. Their story begins with the first century of our Era and Ancient China. Even then, the emperors of the East and Buddhist monks began to maintain, breed and select goldfish.

Actually, therefore, at present there are a great many aquarium goldfish, and their cost can vary from 2 dollars to several thousand US.

So, if you want to feel like a true goldfish breeder, emperor or Buddhist monk, then this article is for you!

Breeding or breeding goldfish, is not a difficult task.

However, goldfish are not guppies and in order to get offspring you still have to work hard and be patient. In addition, you need to have a sufficient number of aquariums or ponds.

You can't get off with one aquarium!

Goldfish breed independently, without any hormonal injections or without creating too specific conditions. Actual, good maintenance and proper feeding is the criterion and incentive for spawning producers. All types of goldfish can spawn in aquariums of a small volume of 30 liters. However, better results can be achieved in larger aquariums or in ponds.

Spawning of goldfish can occur at a temperature of 16 degrees Celsius, but it is better to maintain the temperature of the aquarium water at a level of 22-24 degrees Celsius. After replanting manufacturers increase the temperature by 2 degrees. The water level in the spawning pond should be 20-25 centimeters, the water should often be replaced by fresh and purged.

Unlike many other spawning aquariums, spawning for goldfish should be well consecrated all light day. If it is a pond, then the sunlight should be diffused, and the pond should be equipped with shelters in the form of floating plants.

Producers are planted in a spawning aquarium in the ratio of 1 female to 2-3 males and richly fed with live food (bloodworms, earthworms, daphnia, ground meat with bread, etc.). At the same time they try to select manufacturers based on their size. Especially females - the bigger they are, the more eggs they sweep out. And vice versa - small females toss less eggs. They equip an aquarium with vegetation (such as a combo, riccia, duckweed, a peristist, etc.), and do not carpe the bottom of the aquarium - on a clean bottom the eggs retain and do not die, but some aquarists install a separate grid. Sexual maturity in fish comes to a year of life. In this case, the males appear on the gills white bumps and the so-called "saw" on the front paired fins, and the females are growing stout with caviar, their body is bent. For more information, see: HOW TO DETERMINE THE FLOOR OF A GOLDEN FISH: A male and a female!

A female matured for breeding emits a special substance that has a characteristic odor and is particularly concentrated in the genital organs. Actually, this smell attracts males and is a signal of a female's readiness for reproduction. Under the influence of this secretion males begin to swim for females.

Under pond conditions, it is recommended to perform the above spawning manipulations in March – April, with the expectation that spawning will begin in May – June. It is believed that this is the most prosperous time for the successful ripening of caviar. In addition, at this time it is easier to provide the eggs and fry with the necessary comfort.

If the courtship of the males began earlier than March - April and the spawning should be delayed, the producers are seated and also the water temperature is lowered to the desired period (period).

The peak of reproduction of goldfish is accompanied by violent courtship of the males - they chase the female around the reservoir, and on the day of spawning, these courtships look like a frank pursuit.

Taking into account such features, the spawning aquarium is equipped with soft aquarium plants and not sharp decor (it is better without it at all). Otherwise, the fishes will sweep, and their fins will be torn after spawning.

The spawning begins with the first rays of the sun and lasts 6 hours. Spawning gold can every month until October. During one spawning, the female can sweep up to 3000 eggs. In the "home" spawning of goldfish can sometimes occur continuously - year-round. However, this leads to the exhaustion of manufacturers, and in this case they should be given rest, seated in different aquariums.

Caviar ejection occurs gradually. - the female driven by the males touches the vegetation or the walls of the aquarium and releases 10-30 eggs, which the males immediately fertilize - watering the eggs with milt.

Then, sticky caviar falls to the bottom or sticks to the plants.

Eggs on the first day are slightly orange and slightly flattened, the diameter of eggs is up to 1.5 millimeters. On the third day, the eggs are straightened and discolored, in connection with which they are difficult to detect.

Immediately after spawning, the producers are removed from the spawning tank, otherwise the offspring will be eaten.

The water level in spawning caviar is reduced to 10-15 centimeters and protected from overheating and excessive sunlight (if it is a pond). Aquarium intensively aerated.

The appearance of fry from caviar depends on the water temperature. At a water temperature of 22-24 degrees Celsius - the incubation period is 4-5 days, but at a temperature of 14 degrees Celsius it can reach 7-8 days.

On the second day after the appearance of the young in the aquarium, it is recommended to launch snails (for example, coils) so that they eat the dead and not fertilized eggs. You can carefully assemble yourself, but it is more difficult than it seems. It is very important not to kill the young. At the same time, leaving the dead calf is fraught with - live larvae do not tolerate "dirt" and can get sick.

Young goldfish in the first days is weak and harmless, in fact it looks like a reed with eyes and a yolk vesicle in the middle (the yolk bubble is necessary for obtaining nutrients in the first days of life). Fry move in spurts and can stick to the stop.

After about 2-3 days, they begin to blithely float around the reservoir, and from this point on, the young need to be fed with starter feed: live dust, the finest alga, and other finely ground to feed dust. After 2 weeks, you can give larger feed. At the age of one month, juveniles are capable of taking small bloodworms. As a starter feed, they also use egg yolk finely ground in water, as well as the soaked oatmeal grated in the dust. The fry are fed abundantly, but in portions - little by little but often.

We can recommend the following feed for young goldfish.

JBL GoldPearls mini is premium class granules, packaged in 100 ml.

It has a special recipe ideal for young fish. The diameter of the granulated feed 1-2 mm. Contains spirulina and carotenoids, which contribute to the development of good fish color, contain proteins (10%) from wheat germ, fatty acids.

After two weeks the fry are planted in a 30 liter aquarium at the rate of 250 fry per aquarium. Aquariums flush or replace water frequently. Without purging, it is recommended that 120 fry be planted per aquarium. So they contain up to 2 months of age, gradually sorting by size and reducing their number. Fry are caught not with a net, but with a saucer or other utensils. So they are easier to get and count.

Sorting carried out on the principle of rejection. Harvested juveniles with defects, juveniles lagging behind in growth, etc. In the end, get pedigree goldfish.

Defective and non-standard young, unfortunately kill. First, because it, as a rule, does not survive itself, and secondly, even if it survives, nothing good comes out of it.With its further content, you risk getting outbred offspring "bastards", but if you go further, then the fish just degenerate into goldfish.

At first, the scaled juveniles of goldfish have a silver-gray color, like the progenitor of the goldfish. Coloring appears only at the age of 3-5 months. To improve the brightness of the fish color, it is recommended that "sunbathing" light should be diffused. In an artificial reservoir, no shading is necessary, on the contrary, the aquarium is intensively illuminated with lamps. It is worth noting that the color of goldfish can vary in fact a lifetime.

Scaleless fry do not pass the aforementioned period of silver color and already at two weeks of age begin to turn into their final color.

Juveniles of goldfish are very capricious and prone to disease. To avoid mortality of offspring, you should regularly monitor the cleanliness of the aquarium, aeration and filtration. Constantly monitor the population - do not forget to settle as they grow.

When breeding goldfish need to strictly observe the species crossing. All goldfish can interbreed with each other (for example, veil tails with comets).

Summing up, you can make a short list of what you need for breeding goldfish:

- one-year-old males: 1 female, 2-3 males.

- aquariums: the main from 150 liters, spawning from 30 liters, aquarium for youngsters; (aquariums should be illuminated).

- aquarium soft-leaved plants;

- of course: aeration, filtration, thermostat;

- feed for fry;

- improvised aquarium equipment;

- suction water;
