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 simpler: 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.
For aquarium lovers, the question of how to
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!

Conditions of keeping and breeding fry
Males and females of different types of mollies may be neighbors and not in conflict, therefore, living in an aquarium with a company of other fish is only a joy for them. They prefer to swim in the upper middle layer of the tank.
During the day, they move alone or in small schools (flocks), and at night they form one joint, swimming in the upper ball of the reservoir.
In order for different types of mollies to live comfortably in an aquarium, 10-20 liters of water are required for 1 individual. For fish of one species, an aquarium of 80 liters, for different species – 110-120 liters. At least 3 females should be settled on one male.
Fish can breed in the general aquarium (on the condition of a small population) or in a prepared breeding ground. To breed the fry, producers need to be fed for 2 weeks with vegetable food.
Look at the spawning of mollies.
Comfortable conditions of maintenance guarantee spawning in a month or two after settling in a new “house”. The cone-shaped organ of the male genopodia is used for fertilization of the female: seminal fluid is transmitted through it, it also allows you to hold onto the female during breeding, and the ability to become pregnant increases.
In fact, pregnancy does not come so easily. Only 1 in 10 copulations ends successfully.
Males become sexually mature at 8-12 months, females at 5-6 months.
Breeding of all types of mollies is not difficult for the responsible aquarist. However, the fry of this fish are sensitive to water parameters, in particular, to its pollution, so you will have to change the water frequently.
With successful copulation, the male fertilizes at once many eggs, in which the fry begin to develop. Some mature and are born, others remain inside the female until the next generation.
In the absence of a male in the aquarium, the female can give birth to another 35-50 days at intervals.

Maybe it would not be entirely correct to recommend mollies for beginner aquarists for breeding, as this fish is rather difficult and with complaints. However, if you read the rules of its cultivation, and they do not seem too complicated, then why not.
The question “opened a pet store. Business is not going. What to do? “- 2 answers
Mollies are small fish belonging to the family of the Pelzites. They are viviparous.
Thanks to breeding, there is a large variety of these fish, but in any species the males are smaller than the females. Natural habitat – the central part of America.
Conditions required for procreation of mollies
For a successful breeding of mollies, an aquarium with a volume of at least 60 liters, and preferably 100-liter, is required. Also, do not forget about water quality. The water temperature in the aquarium should be about 26-28 degrees.
To comply with this condition it is necessary to install a heater.
It is imperative to add a special salt to the aquarium, as the ancestors of mollies lived in brackish water. The calculation is as follows: one tablespoon of salt per 20 liters.
You can feed molliesia feed in the form of flakes, frozen bloodworms, if possible, buy live or frozen Artemia; black worms – give about three things a day.
Do not forget to change the water in the aquarium: 20% water every week. Another important factor: the females need peace of mind. You need to make sure that no one is worried: whether it is the males or other inhabitants of the home reservoir.
If this fact is the place to be, then males should be transplanted, or the number of females should prevail.
If all the above conditions of mollies are met, then the long-awaited result will not keep you waiting any longer, and in about a month the female will produce offspring. The female, without the help of a male, can produce offspring several times, therefore, when she becomes pregnant, there is no need to keep the male in the aquarium.
Before the birth of offspring, the female should be transplanted into a spawning tank.
Fry, after the birth, remain in the spawning aquarium. The rate of growth and development will directly depend on the quality of water and food (its quantity), temperature, etc. The generally accepted norm: the fry have become twice as large – you can repot!
What and how to feed them? Flakes, rubbed them in powder, using a plastic bag: 1-2 tablespoons of flakes placed in a bag, remove unnecessary air and then knead it for 10-15 minutes.
In order to feed the fry with this powder (you need a small amount), take a toothpick, soak its tip in water and dunk it in food, and then immerse the toothpick in an aquarium. This procedure must be performed several times a day.
How to breed goldfish :: goldfish breeding :: Aquarium fish
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 store. Business is not going. What to do? “- 2 answers
1. There are many varieties of goldfish. To obtain a good and “high-quality” 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.
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.
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.
These ornamental carp reach sexual maturity from about four months of age and are then ready for breeding. An interesting feature: at an elevated temperature of the aquatic environment (+ 30 °), maturity begins with three months.
Reproduction can occur both in the general aquarium and in a special spawning ground. Even a three-liter jar is suitable for this, as ornamental fish are unpretentious, and the couple will be able to give offspring even in such Spartan conditions.
In principle, the type of tank is not so important, the main thing is to perform a number of activities to create optimal conditions for the reproduction of offspring: the appropriate temperature and the presence of green vegetation (Javanese moss, for example), in which future fry will find their shelter.
Most experts are unanimous on the question of how to provoke the reproduction of guppies: this is an increase in temperature in the aquarium by 3-4 degrees and the replacement of about 1/3 of the water in the spawning (or general) aquarium. Naturally, the water must be separated.
However, some professional aquarists insist that such provocation is needed only in a strictly defined case, when the guppy is difficult and premature.
When the male begins to chase the female, snuggle up to her from the side or bottom, mating begins. There is an important feature: if the fish are in the total volume, then you need to ensure that there are not too many males. They can drive a female to a state of complete exhaustion, there have even been cases of death of females in such conditions.
Therefore, the ideal option – a couple of individuals.
The male fertilizes the female with the help of a special sexual organ, which has the scientific name of gonopodia. At its core, this is a modified section of the fin in the form of several tubules, which only adult males have.
How a Danio aquarium fish breeds: conditions :: danio aquarium :: Aquarium fish
Even the beginner aquarist will have no difficulty in obtaining the offspring of the zebrafish aquarium fish. Despite the fact that this is not a viviparous fish, but spawning, time and cost will need a little: a small horizontal aquarium, several plants, pebbles and two weeks of patience.
The question “opened a pet store. Business is not going. What to do? “- 2 answers
Danio is a small, peace-loving schooling fish of the carp family. In nature, they live in flowing or stagnant reservoirs of Asia.
They can even live on paddy rice fields. They are not demanding living conditions and are suitable for content for beginners.
Aquarium zebrafish grow up to 5 cm long, have an oblong body. Color can be of different shades – from whitish to silver, golden, pinkish, depending on the color of narrow longitudinal stripes on a light background. Danio is omnivorous.
In aquariums, they usually live 2 years, sometimes 4-5 years.
The zebrafish are small, so a horizontal glass container with a capacity of only 3-5 liters will be suitable as a breeding ground. 3-4 plants are laid out on the bottom, which are pressed down by smooth pebbles.
Separated water is poured into the tank, the temperature is 24-25 ° C.
Zebrafish reach sexual maturity in 4-10 months. For the best spawning, experts recommend a week before that every day in the aquarium change up to 20% of water.
Fresh water should be separated and have a cool temperature of about 20 ° C.
Then, 3 days before the spawning of females and males, it is better to plant them in different aquariums. The female is distinguished from the male danios by a more rounded abdomen and clearer stripes on the back.
Fish during this period are actively fed high-calorie food, for example, bloodworms or koretira.
On the appointed day, the spawning area is transferred to a well-lit place and one female with a belly that is clearly thickened at the anus and two or three active danios are planted into it.
After the fish settles down, spawning occurs the next morning, at dawn, or in a day. It is interesting to observe how the males start chasing the female and chasing her all over the breeding ground, striking directly at the belly of the fish.
Thus, they stimulate her to release caviar, which is immediately fertilized.
Caviar gradually, approximately within an hour, precipitates and attaches to the bottom of the spawning grounds. After spawning is completed, danios are transferred to a common aquarium.
Pebbles from the bottom of the spawning area are removed to make the plants surface. At the same time, transparent balls-eggs are clearly visible.
After 3-5 days, fish appear from the eggs. They grow quite intensively.
Juveniles are fed with infusoria, “live dust”, and special food for fry.
The zebrafish lays up to 400 eggs, but no more than 100 fry survive to an adult state. Within a week, the female is again ready to spawn.
