I think it is a molly baby, well it's got to be if that's all you have in it, and if there are more babys in the tank, they're probly gone now, if your fish has babies and there in the tank, all of the fish encloding the parents, will feast. Also to feed the fish I would recomend brine shrimp, or if that isn't an option, finely crushed flakes would be o.k. Also mispelling that much is NOT cool, and makes it very hard to read. Also right now I have platy fry, themother died, and they don't move much. So it's not that unlikely, as long asthey aren't floating I think that they are still alive. Did you cycle your tank first? Or if you didn't then you need to. It is slowly killing your fish, here is a paragraph that explains it alittle better,
