Now I am nervous. I have a 29 gal and I hear clicking alot at night. I wasnt sure if it was a crab I had that lives in the rock or what. I know there is a decent size crab but he never comes all the way out of the rock so I never get to see him. I havent had anything come up missing or dead. It would have killed something by now I would think. I have had the tank up and running for about 9 months now. Do I have anything to worry about?
