Last week I discovered a pair of crabs hiding in one of my acro colonies... have not had this one before and wondered if I could get assistance on a quick ID on the specific type of coral crab it is. I've seen the white and red ones, the white and black ones the the hairy ones... etc; but not this one. They are little guys; no larger than dime size if that... there is one in this pic... the best pic I've been able to get of one of them so far.
