here's what i do and it has worked very well for me:
Get a hang on breeder net, about 5 bucks at your LFS or wal-mart, it's just a square tiny net that hangs on your tank that you scoop up the fry and put them in there, to keep them for being eaten. make sure it's not directly in front of the filter, so that their not getting blown around too much, but make sure it's not in a dead spot either, you want fresh water going over them so that the overfeeding that you do doesn't create an ammonia bloom, either. I take reg. flake food and put it in a ziplock bag and crunch it into a powder with my fingers, they do eat alot so make sure to put plenty in there. don't keep them over too hot of lights either, since they are in a breeder net, they can't swim away from the heat. i feed mine 4-5 times a day, my mollies were born on Superbowl Sunday and they are already back swimming with the "big dogs" and no one messes with them. when you feed them in the breeder net, just take a pinch and drop it in so that it covers the whole top area, they will quickly gooble it up and just make sure not to dump so much in there that it's polluting the area but enough for them to all eat well. like i said, 4 or 5 times a day. Good luck. just so you know what i have, 2 mollies, 1 male / 1 female 2 platys 1 male / 1 female. we DO NOT HAVE A SHORTAGE OF FRY IN THIS HOUSE. LOL
