Raising your fish from the home aquarium is possible and more accessible than you imagine. You may have never found yourself with tiny babies in your aquarium overnight without even looking for it. This is because sometimes you buy female fish that are already fertilized and give birth when they live in the right conditions.

And there are many types of aquarium fish that reproduce with great ease. So the only thing you need to know is which pets are easier to raise, what happens during the spawning period, and the favorable conditions for sound reproduction.

Choice of Fish

Some pets are better than others when reproducing in an aquarium. This is mainly due to the differences between an ‘ovoviviparous’ fish and an ‘oviparous’ fish:

  • Ovoviviparous: these are those fish whose eggs remain inside the female fish until the embryo has fully developed.
  • Oviparous: this type of fish expels the eggs after fertilization, and they are deposited in the environment in which the family lives.

In any case, ideally for breeding fish in an aquarium, buy a group of 6 or 8 young fish to pair naturally in the aquarium, which will increase the chances of successful reproduction. 

In addition, raising the fish from a young age will have an extra benefit, and that is that you will know the evolution of each of them and what food and what conditions favor them the most.

However, if you are a beginner in fish farming, you should know that there are three very easy breeds to breed :

  • The Guppy: it is ovoviviparous, very resistant to any condition, peaceful, and prolific. The ideal fish to start your hatchery.
  • The Goldfish is one of the most popular fish in home aquariums. It is also resistant, adapts very well to captivity, and lives with other fish.
  • The Cherry Barbel: also ovoviviparous, is so prolific that it can reproduce almost every three weeks. However, a problem that this fish presents is that barbel fry needs a balanced and correct diet to survive.

The Spawning Period of the Fish

The spawning period is when females lay their eggs and incur significant expenditure of vital energy. However, you must consider this aspect since once the female has finished this process, you must provide the fish with a well-oxygenated, calm environment and an almost constant feeding.

Some fish will eat their young during the first laying but don’t worry, then they learn to take care of them, and you will be part of a beautiful stage. 

After the spawning period, it is appropriate that you consult your veterinarian since, depending on the fish you have, they will act in one way or another.

Scalar fish, for example, must be separated after hatching. On the other hand, as for fish such as labyrinths, you should know that the females must also be removed after hatching but the males not, since they must first teach the fry to swim.

Raising fish in the aquarium: everything you need to know

Conditions for the Good Development of the Offspring

Depending on the type of fish you raise, you will have to guarantee them a series of conditions necessary for their fry to develop correctly. 

Whatever your type of pet, you will have to take care of aspects such as the type of aquarium, the water temperature, and the feeding of the fish.

The Aquarium

If you decide to raise the fish in your aquarium, you will need to place aquatic plants with thin leaves in which the fry can take refuge from the adult fish. It is recommended that you put several in one corner of the aquarium, near the bottom, and others floating closer to the surface. In addition to serving as a refuge for the fry, the plants will also provide tranquility to the female, who will surely settle there to lay her eggs or when she is about to hatch.

The Water Temperature

The state of the water is something that you must take care of every day since otherwise, your pets will not be raised properly. Therefore, both the temperature and the cleanliness and acidity must be adequate.

Take care of hygiene: fingerlings or young fish are more exposed to infections or diseases than adults.

Take the water temperature every day: if your aquarium does not have a thermostat, you must ensure that the water is not at a higher or lower temperature than is recommended for each type of fish.

Watch the PH: fish need a specific PH to live correctly, so you will have to consider this aspect when raising them.

Feeding the Young

A fingerling eats very differently from an adult fish, and that is that they do not need as much food, nor can they consume such large pieces of food due to their small size.

During the first days, they are fed infusoria cultures. A week later, it is advisable to provide them foods rich in nutrients, such as freshly hatched saltwater shrimp, known as brine shrimp. 

The next step in developing the hatchlings is that they consume dry flake food and live food such as daphnia, which is mosquito larvae, newly hatched or adult shrimp, and small Tubifex worms. However, it all depends on the type of fish, as herbivorous fish will need to be fed algae, peas, or lettuce.
