Nothing, really. Peas for one. It's 'supposed' to be for bloat. Only feed VERY small amounts. Hardly anything at all. it's only for bloat so you can't use it now, sorry. Nothing. My dad had an Oscar before. :)
Over hundreds of bettas die in their small, dirty cups each day. Only you can help them live. Research and then save them, today!
I feed my bettas a VERY occasional treat of cooked plain shrimp. They absolutely love it. As long as it's plain, it should be fine to feed them pieces about the size of a betta pellet. I see no problem feeding them shrimp as long as you are careful how much you feed them.
