Aquarium viviparous fish are widely known among aquarists, amateurs and professionals. These fish have gained wide popularity due to simple maintenance, unpretentiousness and easy reproduction.
These fish were named because unlike other fish that spawn, viviparous fish give birth to fully formed fry, who from the first moment of their life can hide from adults in the grass thickets and independently look for food.
Viviparous fishes are represented by a large number of species, they inhabit the waters of both South America and Asia. They live in slow-flowing or standing reservoirs with fresh and brackish water.
In aquariums among viviparous fishes, the most popular species are guppies, platies, mollies, swordtails, ameks, formose, limii and others.
In the care and feeding of viviparous fish there is no equal, they actively eat any food, grow well even from dry daphnia, withstand a wide variation of water parameters both in hardness, temperature, and in pH. The undoubted advantage is that salt can be added to aquarium water with various species of viviparous fish for the treatment of certain diseases.
Viviparous fish easily carry a small amount of salt in the water.
Most of the viviparous fish have very good sexual characteristics, if you plan to propagate these fish in your aquarium, then in the pet store you can easily pick up males and females. They grow very quickly, some species become sexually mature by the age of 8 months and females may become pregnant. Fry develop in the abdomen of females in different species from 30 to 60 days.
To stimulate reproduction, no special requirements are needed; it is enough to maintain clean water in aquariums and feed the fish well.
Sexual Differences of the Sword
In aquariums with viviparous fish there should be a lot of plants, especially if you plan to breed fish in a common aquarium. The fact is that adult parents sometimes eat their offspring. In nature, these fish live in ponds with a large number of green plants, and fry can swim away from their parents after birth.
In the general aquarium such a trick will not work and the offspring will have to survive in those shelters (plants) that they find, otherwise all the fry will be eaten. But if you plan to breed your viviparous fish, then it is better to purchase a spawning aquarium specially prepared for them.
Fry of viviparous fish
Due to the fact that viviparous fish breed easily and quickly reach puberty, even beginning aquarists can try their hand at breeding various species of these fish. Crossing of live beetles is a very exciting activity, fish with a very beautiful color and unique fin structures can be born.
If you intend to cross live-grouper, then it is necessary to settle males and females in different aquariums after the sexual characteristics appear in the fry to avoid random interbreeding.
