ID This Huge Crab?

[gordonzo]

Two of these came with my live rock. One I have been feeding shrimp pellets. The other I did not know about until he showed up dead in the corner of my tank 1 month after setting it up (see photo)! Overall 2" across. Body 1" across. Is this a Porcelain Crab? He seems to be very shy and 'runs' from my Damsels.

Looks liek an emerald crab. If you look in our links area you will find a link to a hitchhikers FAQ. There should be some photos of common crabs that come on your rock that you can compair body shape and color to the crab you have.
