so i saw two cleaner shrimp in my tank. weird because i only bought one...upon closer inspection, one was from his molting. pretty cool. the shell from him is attached under a ledge and still has color on it and tentacles. looks like a live one. then i found what i thought was my emerald crab, dead. seeing the shrimp has molted, i was wondering if emerald crabs do the same, and maybe my emerald is not dead, but just molted?
