From what I know they need a regular diet of crustaceans of some sort. Snails or ghost shrimp. It wears their teeth down. If they don't have these in their diet, the teeth might outgrow the mouths making it impossible for them to eat, and you'd have to file them yourself somehow. Don't quote me on this, I'm regurgitating Soulfish advice from memory.
