So about a week ago I bought a pregnant platy form the store and she dropped today while I was at class. I found some half-eaten fry in the rocks and so forth when I got home. Since then, I placed the fry (about 10 or so of them) in a nursery tank. I've lost a few to swim bladder, but the rest seem to be doing well. I grind up topical fish flakes into a fine powder. Is this okay? I am a college student, so i can't be spending a lot of money. I've kept tropical fish before, but never bred before. So, any sugestions to a newbie breeder?
