Care for Freshwater Baby Molly Fish - Gather the babies. The best-case scenario would be to have the pregnant female in a breeding box or net suspended in the water of the aquarium. In the case of a breeding box, the babies would drop into another compartment of the box and the mother would already be separated. In the case of a breeding net, you would have to scoop the mother out.
If chasing tiny mollies around the aquarium doesn't do it for you (it also stresses them out), or you just want to give the babies a little more protection, add more plants to the tank---real or fake. Plants with leaves that float to the top of the tank will give the little ones a place to hide as they feed. Breeding grass also works for this purpose.
Care for Freshwater Baby Molly Fish
Feed your fish. Baby mollies can eat your regular fish flakes, crushed finely. Live baby brine shrimp are also a popular baby food. Do not overfeed your fish. In about eight weeks your baby mollies should be large enough to go into the tank with the other fish.
The molly (Poecilia sphenops) is a popular fish for the beginning aquarist. They're attractive and hardy and, given enough space, can get along with others. Mollies belong to a class of fish called livebearers. They don't lay eggs; their young come out swimming. And they are prolific breeders as well.
Molly babies get no protection from their parents. The tiny fish are just as likely to be eaten by their own mother as they are by other fish in the aquarium, so to survive they're going to need a little help. - by eHow
