How To Get Fish In An Aquarium

If you want to not only admire the fish in the aquarium, but also regularly increase their number, we recommend that you familiarize yourself with the breeding conditions of these aquatic pets.

Breeding fish in a home aquarium is perhaps one of the most difficult moments of aquarism. Here, desire alone is not enough; special knowledge and certain experience are needed. This article will try to reveal the features of breeding aquarium fish at home.

General information about the breeding of aquarium fish

By the method of breeding aquarium fish are divided into calves and viviparous. In any case, for the production of offspring, a mature male and a female of the same species must be present in the aquarium (Figure 1). Their external differences can be both pronounced (Killy fish, cichlids), and non-permanent (carp, haratsinovye). Therefore, it is recommended to acquire at least 5 individuals of the same species at once, in order to get the offspring guaranteed.

Figure 1. Rules for breeding fish at home

Some species of fish, such as discus, do not want to pair with any individual of the opposite sex of their species. Often, the selection of a pair for them takes a long period of time. But once having formed a pair, the discus remain faithful to each other all their lives. In this case, it is better to purchase a pair that has already formed, or a group of young fish for general maturity and the formation of a possible pair.

What types of fish is beneficial to breed

Years of experience show that the following breeds of aquarium fish are the most beneficial for breeding as a business: cichlids, barbs, synodontis and goldfish (Figure 2).

Figure 2. Popular species of aquarium fish for breeding: 1. cichlids, 2. barbs, 3. synodontis, 4. goldfish

Among all these species, goldfish and cichlids have the highest ability to reproduce. Synodonts and netterous fish occupy threefold place, and barbs have the lowest ability to reproduce. Such species as guppies, gourami and betta are also easy to breed. And yet, despite its unpretentiousness, these types of fish also have special care features that need to be known.

Cultivation of short-lived species

The females of aquarium fish of the killing species lay eggs in the aquatic environment, and the males release their seed for their fertilization (Figure 3). The incubation period of eggs lasts about 36 hours, but since it was during this period that there was a significant threat from other inhabitants of the aquarium, some species of calf fish adapted to lay eggs in caves, on the underside of leaves of aquatic plants, etc. Separate aquarium fish protect their laying from extraneous interventions, there are those that carry eggs in their mouths.

Two methods are used to stimulate spawning of ringed fish.:

  1. Daily feed of protein-rich food, which promotes caviar and milt formation.
  2. Changes in the conditions of the aquatic environment (for example, replacing part of the water with fresh water, lowering or raising the temperature and water level).

At the beginning of the mating season indicate the color and behavior of fish. So, males become more vivid, and their behavior. aggressive. At the same time, different types of fish spawn in different ways: in pairs, breeding groups, schools. Depending on their behavior in a given period, the scenery for the spawning aquarium is selected.

Diving game in the ground

The method of immersion of caviar in the ground is enjoyed by the Killy species, which, during spawning, lay eggs in the bottom substrate. Even in case of drought, the eggs remain viable. Therefore, in the design of an aquarium for this type of fish, special attention should be paid to the ground (Figure 4).

Figure 4. Reproduction of fish by immersing caviar in the ground

Peat or coconut fibers should be its basis. After placing the eggs in the ground, it is removed from the water and can be stored in a warm and dark place for several months.

Nest of bubbles

The male of the labyrinth fish, having formed a pair, begins to build on the surface of the water a nest of particles of plants and all kinds of rubbish, fastening it all with foam from small bubbles. The female lays her eggs in the prepared nest and protects her until the appearance of offspring (Figure 5).

Figure 5. Reproduction of fish with a nest of bubbles

Therefore, for the design of an aquarium intended for breeding labyrinth fish, it is necessary to provide for planting tall and floating plants in order to provide the male with building material for the future nest. Such an aquarium should be equipped with a tight lid to form a warm layer of air on the water surface in order to protect the labyrinth organ of fish from hypothermia.

Spreading eggs

Some species of carp and heracin fishes spawn in small flocks. In this case, the females scatter the eggs on the elements of the design of the aquarium, not showing maternal instincts and eating their own eggs.

For them, the best decoration of a spawning aquarium is a ground made of small glass balls and a grid with small cells. Such a device helps to protect the eggs from eating their own parents.

Masonry formation

Discus and scalaries are known for their loyalty. They form permanent pairs for spawning and care for the offspring. These types of fish attach eggs in secluded corners away from prying eyes and remain nearby to protect them. Therefore, in the design of the aquarium should prevail floating or well-rooted plants with wide leaves.

Breeding of viviparous aquarium fish at home

Viviparous species of fish differ from the calf in that the fertilization process takes place inside the body of the female. Fry of viviparous fishes are born completely formed.

Note: Interesting is the fact that females are able to keep the seed of the male throughout their life and successfully use it to reproduce offspring. However, viviparous fish completely lack the parental instinct, and young individuals can easily become a victim of both predators and their own parents.

Therefore, to save the fry, it is recommended to use a special trap. It is a transparent chamber with a double bottom and small holes made in it. A pregnant female is placed in a trap. During spawning, newborn fry, through cracks at the bottom, enter the middle chamber, where nothing threatens them. After spawning, the female is released, and the contents of the camera with the fry are poured into a separate container.

Feeding fry

The first stage of breeding passed: the fry were born. Now it is necessary to provide them with a sufficient amount of the desired feed (Figure 6).

Note: It is important to know that at first they can only consume liquid food from microscopic aquatic inhabitants (ciliate infusoria). Water droplets containing these organisms are fed to the surface of the water with a conventional syringe.

Such feeding takes a lot of time and money, since it is necessary to carry it up to 4 times a day. Therefore, when keeping unpretentious species, it is practiced to feed the fry with ground flakes. They are also mixed with water and transported to the surface of the aqueous medium using a syringe. As young animals mature, they include small-sized daphnia and Artemia nauplii.

Figure 6. Features of feeding fry in an aquarium

Since fry of aquarium fish do not have high activity, it is necessary to organize their feeding so that the feed is distributed evenly over the entire surface of the water and is easily accessible. So, soft filtration in the process of mixing water contributes to the delivery of feed to all corners of the home water reservoir.

Problems in breeding aquarium fish

As in any business, when breeding aquarium fish at home is not without difficulties and problems. Consider the most common of them and try to identify ways to overcome them.


Overpopulation is the excessive amount of fry in a certain volume of the aquarium. With proper care, the young growth is continuously growing, and the living space of each of them is getting smaller. This lack of space causes growth retardation in fry, leads to stress and water pollution and, as a result, can cause various diseases. Therefore, as the fry grow, a larger reservoir should be prepared for them in order to increase the living space at the right moment.

Population degeneration

Some species of fish become very mature at an early age and, if they are kept together, they may enter into closely related bonds that lead to a degeneration of the population.

Therefore, young individuals of viviparous fish, as well as fish of the Killi species, should be settled in separate containers (for keeping males and females). To distinguish them quite easily in appearance: the color of the males is brighter.

The problem of population degeneration is also characteristic of the joint keeping of closely related fish. For example, it is not recommended to keep Swordsmen, Petsylias and Plyatipelylii in the same aquarium, because as a result of their interbreeding, hybrid progeny appear that are incapable of reproduction.

Fry mortality

Sometimes not too shredded food or poor water quality causes mortality of the fry. If, upon careful examination of the fry stomachs through a magnifying glass, you do not notice the inside of the food particles, this means that the young animals are starving because they cannot absorb too large pieces of food. With insufficient or poor care for the aquarium, the fry may die due to water pollution from waste products and food residues.

No offspring

There is a situation when adult healthy fish either do not produce caviar, or no offspring leaves it. Lack of offspring is often associated with males. They may be old or damaged by gonopody. In this case, the problem is solved by replacing the male.

Breeding aquarium fish as a business

Breeding aquarium fish is not only an exciting activity, it can be quite a profitable business. After all, you can do it at home, which significantly reduces the cost of starting your own business. In addition, an entrepreneur is not obliged to have a special education at all; there will be enough desire, some baggage of knowledge and material capabilities (Figure 7).

Figure 7. Aquarium fish breeding business

And yet, the choice of aquarium fish should be approached thoroughly, because there is a temptation to start breeding fast-breeding fish. Their cost is low, and the opportunity to start a sale fairly quickly is very attractive for an entrepreneur. However, it should be noted that such fish species, as a rule, do not represent special value, and therefore their offer on the market is high. At the same time, their prices are low, and therefore the sale will not give a good profit. There is also a risk when breeding species about which there is very little information in the public domain.

You should know that imported fish from hot countries breed very slowly, or are not able to reproduce at all in conditions alien to them. In addition, before purchasing exotic species, the requirements for their conditions should be well studied. After all, improper or inadequate care can cause illness and even death of the fish, and accordingly, this will result in your business at a loss.
