I've always just given my fish a variety of fish food, flakes, pellets, krill, bloodworms, beefhearts, you know all common fish foods. However, I hear all the time about people giving their fish [like an Oscar which I also have]...different human type foods...I'd llike to venture into new type foods for fish like...Oscar, Frontosa, Green Severum, Pacu, Red Tail Cat. What is the most un-common food you've given a fish?
