This guy hitchhiked on a piece of rock.

Friend or foe?

Looks like an emerald crab to me. I have two dam near paid ten bucks for one

Disagree with above... looks more like an Xanthid crab, which are generally considered bad. The black tips to the claws are generally a bad sign. Any chance you could snag a clearer photo of the crab? (I wouldn't just jump to flushing it, some people actually want these, but I might try to isolate it if you can catch it)

Looks very similar to one which did a number on my Emeperor Angel which was removed and fed to my 18" Queen Trigger (Snack).

If has rounded pincher, it should be ok but if has sharp/pointed pincher, I would removed if and when possible via crab trap.
