I noticed several days ago that one of my emerald crabs is missing both front claws and maybe a leg. Maybe he got into it with another emerald crab or one of my fish. Every night I've been rubber-banding nori to a piece of rock and placing it on the sand near where he hangs out. He really goes to town on it, but I don't know if it's enough to keep him going until the claws grow back. I thought about trying to catch him to put him in a little 5-gallon tank I have running now in case he's being bullied, but I don't know whether I'd be doing him any favors.Anyone ever deal with something like this?
