New Crab found needs identification please.

[johnsz02]

Hi I have recently seen this little guy poking around underneath one of my mushroom corals. He seems to pick and eat at algae on the rocks but he will also eat bits of shrimp I hand feed him from his hole in the rock.
Any help with identification would be appreciated and also if he is reef safe or not?

Oh and also this is just a fresh molting of the crab, dont know if that makes a difference.

Thanks

Looks like a gorilla crab (xanthid species). Bad crab. http://www.tampabaysaltwater.com/thepackage/watchout.html
