Unresolved I have crabs...help!!!

thanks for the info i think he probablly did die, the other one did and they were in fresh water for over an hour. I tapped him and he moved very slowly and that was after 20 mins so i would assume over an hour would do it. The one that might still be in the rock is actually a different kind of crab to the one in the picture...i think he may be a gorilla crab as he looked a little hairy and was slightly larger than the one in my photo.

Anyways thanks everyone for your help..glad i joined this site
