Can you help me with my pregnant sunburst platy?

I too have a pregnant platy on my hands, and the first thing you should know is that they will eat their own babies, they do not realize they are living things and are opportunistic feeders. I would suggest buying a breeder trap, this separates the mothers from the rest of the tank and when the babies do pop out, they swim down through a crack in the plastic, into a small protected space. Platies, guppies, mollies and endlers are all live bearers, meaning their babies come out alive, able to swim, although weakly. Do not let the pet store workers let you buy an isolation net, as the mother will still be with the babies and will eat them in that confined space with no plants or other protection. This happened to me and I needed to go back to the pet store to buy a more appropriate breeding trap. Their stomachs will get huge, you will know if they are pregnant. You will need to keep the fry separated from the other fish until they are 2/3 the size of their parents. After that, you could buy another tank to put them in, as your tank is overcrowded as it is, or you could sell them to a local pet store for about 10 cents a fry.
