I'm going to be using platies. My husband took over my 30 gallon tank and will be filling it with platies and tetras. He won't make a special effort to protect the babies. When they get too numerous, I'll be feeding them to my 14 inch jag hybrid. My brother might take some too. He has salt fish that sometimes like feeders. My mother thinks he and I are awful, taking pets and feeding them to big fish. I told her that no one feeds pellets or flake food along the Amazon or the lakes. What did she think big fish ate in natural habitat? She was not amused...
