Ugly crab id

I think this liitle bugger has been attacking my corals. What is this beast??

I can't tell. The image is too blurry. Crabs with black claws are often in the group referred to as xanthids. They are predatory and are not good for reef systems.

I hope there are no more of him:)

Thanks
