You just have to be a responsible fish keeper and quarantine your feeders. That and be smarter than a single celled parasite. I like to treat my fish as natural as i can. And i can never once remember seeing a pellet floating around in a stream. But then again i have never been to the amazon, maybe there is pellets naturally floating around the amazon. Who knew.rallysman;2426579; said:I guess it is boring not having to worry about parasites. Man, I wish I had the excitement of trying to keep fish I didn't care about alive![]()
