I have a fish only tank (hope that is ok for the crabs!), so the arrow crab eating what feathers or aiptasias I have isn't a big deal. I've seen the clown sitting on the sand some nights, and bristle worms are like an inch away from him! I woke him up when that has happened and moved him with a net to get him to higher ground. Tonight hopefully, the crab will go into action!
