The Platy i was worried about gave birth today I've counted about 7 babies. I found my second neon dead and now the mother and the glowlight tetra show signs of ick. I put them in a second tank and gave them ick medicine. My second platy is starting to act the way the first one did about two days before she gave birth. The ammonia levels are dropping and the nitrite levels are climbing. I did get some gravel from a tank that has recently cycled and added it to my filter. I hope that helps, but I'm really not that hopeful on the survival of the babies. Is there anything else I can do? 
Thanks for the encouragement, but it's not just two fish; I already lost several on a first tank from overloading. Now this time I tried to stick to the book I had, and still they're dying. The other adult platy that was in isolation died this morning. I hate to even think what that brings the total up to now. My tank now consists of a pleco, a ghost shrimp, and approx 7 fry platies. I tried to feed them ground flakes as was suggested; however, the flakes usually were ignored. Since I didn't want to build up any more problems then necessary with cycling, I tried placing a piece of algea tablet near where the fry were in a seashell. They loved it. It also makes it fun to watch them eat, and I can tell if it has been eaten instead of just getting mixed into the gravel. This also helps since I have two bottom feeders in the tank with them. What the fry don't eat the other two do. So far none of the fry are MIA, hopefully since the ammonia is back to zero and the nitrate levels are starting to vary maybe they will have a chance. I really wish that LFS gave information about fishless cycling, so that newbies like me knew about it before starting.
