This might be a tough one to answer. I've got a bunch of red belly fry in a little grow out tank- they're about a week old, eating bb brine. I over feed the hell out of them and have noticed a planaria outbreak. Can my fry eat the planaria? anybody have this before? fry's bellies are always full and don't seem super hungry when I feed them but they do eat the bb brine. I think they're also eating the planaria. My tetras and other small fish eat it. I do ro water changes every other day but I can't do much in the way of real cleaning currently because the guys blend in so well with the sand.
