Groyne, my whites ate superworms when we first brought him home, but he hasn't since. I think the only reason he did was they weren't feeding them enough at the pet store. Be careful if you feed superworms though, they are high in chiten ( I think that is spelled right) and can be hard for a frog to pass. We had that problem, but luckly it turned out alright. I hadn't thought about trying any other kind of worm.
