wow thats a good one first guess cause the claws are black i would say bad but on the otherside of things they look kinda scooped and not pointy......

looks like a xanthid crab though

from melev's site

This is a Black Fingered Mud crab - Xanthid crab. He arrived on a coral when small, but has grown quickly. This guy is black in real life; this picture is misleading. His pinchers remind me of a Mithrax crab, but it has 'teeth' within the claws. Because he can't be trusted, he's been transferred into my refugium where I hope he'll be happy and trouble-free. Xanthids are Not Reef-safe.

fuge citizen: great. Tank citizen: bad boy. You can generally judge the crab by the claws even if you can't ID it: no claws or tiny claws, not much problem: claws a major part of body, not good.
