again, one of the prizes of my tank. I plan on ordering several (and i mean several) more when i get the money. He was shy for a few months, but now he is out everywhere, scuttling around and waving those fans out for food. one of the funniest tankmates ever. he eats mysis shrimp like hte rest of my livestock. is actually a shrimp but due to looks its classified as a crab and... umm... they like rockwork alot, places to hide. great buy, especially being the only COMPLETELY reefsafe crab besides a hermit.
