None. There are no animals that can eat rocks! It is very bad for them. It could break there teeth or choke them if they swallowed a big one whole. If you put a big rock or medium size rock in a fish tank then they will bite on that with there mouth but nothinng will happen. Bottom feeders will suck the gunk off the rock that is building up on the rock if you have one .
So dont try giving a living animal a rock to eat because that is just plain Animal Abuse.
