So I have this emerald crab for about six months and I had him in a tank with two clown fish and two other emerald crabs. I came home about three days ago and found him on the bottom of my tank with no legs and just two claws upside down. My husband wanted to youthanise him, but I couldn't do that.
Since he had no legs I had to take hime out of that tank. since it had a plenom bottom. I put him in another tank with a sandy bottom. He seems to be getting around ok without any legs, and I have seen him eating. but he cant really climb on rocks like the others. I have one fish in that tank a clown, and one emerald crab with him. should I be worried he might be eaten? And do they grow their legs back?
