White Hairy Crab

It's really tough with crabs, Usually the rule of thumb is if they have big claws they aren't too good. I would say if you aren't sure you should banish him to the sump, at least until he can be properly identified.

I found a picture on a different site and he's almost identical to this. They called him a decorator crab.

I think they call them decorator crabs because that's about all they are good for...decorating your tank. I'd leave it in the tank if you like it.

Decorators crabs are fine..Kind of funny little crabs..No major issues in a reef tank....
