[Audrey]

I got a piece of new live rock yesterday and these come along.. one guy said the are Emerald crabs, but when I went back today another guy said that they might not be Emerald crabs.. I need help in identify them..

It is a mithrax crab. emeralds are also mithrax craps. The pincers have little round pads on the ends
