i often get black Mithrax on LR, from your description ( very black, mottled body) it sounds like the same beast.

Google the emerald crab and look at the ends of the claws, i would wager they are similar to your mystery crabs.

IF they are the black mithrax (no idea on the specie name) i have found them to be quite reef safe and a good eater of algae, i wouldn't trust them with some LPS and some Softies though.

Defo one for the sump if you have it, brilliant CUC.
