You didn't need a new thread about it, but that appears to be an emerald crab.

The claws look a little different might just be the angle of the pic but I don't see the round pad looking things on the ends of the claws. Not sure what it is.

Tip a long glass on its side and put some food in it. You'll know exactly what it is after awhile.
