Live-bearing aquarium fish
Most viviparous fishes belong to the family Poeciliidae Cyprinodontiformes squad. They produce their offspring not in the form of eggs, but in the form of already formed fry, which have phenomenal adaptive properties. They immediately after birth descend to the bottom, hiding from predators and their parents in the bottom vegetation, and provide themselves with the first food there. With the growth of their ability to hide in the vegetation is only growing, and they often can be found near the surface. At the age of 6 months, they are already able to continue the birth.
In nature, all 140 species of viviparous fish can be found in the standing or slow-flowing water of freshwater bodies in South and Central America and Southeast Asia, as it is there that the environment can offer them warmth and abundance of vegetation. They move in flocks, where both males and females are present. If there are few males, then they can be aggressive enough to show rivalry among themselves.
To make the fish feel comfortable, it should be placed in an aquarium of the appropriate volume:
Mature individual Hupei in the General aquarium requires 2 liters of water;
the volume of the aquarium for Mollinesias-from 30 liters;
on 15 fish Ameki will require aquarium in 60 liters;
one Sword takes 4-6 liters of water in a community tank, a separate minimum volume is 30 liters;
for Pecilia, the aquarium should be at least 20 liters.
For their breeding special knowledge and skills are not required. Rare and expensive species are Preppily, Girardinus, Formosa, Lemhi, Heterandria.
How to keep viviparous fish
Fry have females emerge in for 20 days until 1.5 month, determine pregnancy can be on square abdomen. One female can bear fruit from one male to 8 times, which complicates breeding. The number of juveniles may vary depending on the size and age of the parents, their diet and other conditions. Difficulties with food for fry usually do not arise — they are suitable for Daphnia, Cyclops, Artemia or dry food, live dust, egg yolk. Adults eat leaves of lettuce, shredded seaweed, oatmeal, and even frozen food in the winter. The snail is active, easy to get along with other species in a community tank. The main thing for them:
observe the permissible density of settlement;
leave for free swimming in the aquarium place without algae;
diversify small-leaved living plants – from bottom to floating on the surface.
Replacement of water is carried out standard, these fish are easily adapted to the change in water temperature. Viviparous fish — the most suitable option not only for obtaining the first skills of breeding fish, but also for breeding. Even if you are engaged in the usual breeding of fish at home, you will be so surprised by the variety of fin shapes, sizes and colors of fry that you will want to try to do breeding in practice.
