I've had 2 hermit crabs for about a month now. This is my first time owning crabs. They have been doing fine so far. Today I decided to give them their weekly bath. I picked the one up and put him in the water and noticed he didn't come out of his shell like he usually does. He seems to be dead in his shell but I am not sure. When I pick up the shell his body does not fall out all the way but it comes out a litte and if I turn the shell up it falls back down in...like a dead body. He doesn't smell though. Is this normal at all or do you think he is dead?
