Lately I have been hearing a loud clicking noise in my tank. I have seen a large white crab(3-4 inches across) with one huge claw and one small claw. Question is if he is making the noise or if I have a mantis. I rarely ever see this crab. How does one catch either this large crab or find out if I have a mantis. This tank has been set up for over three years. I have only added fish in the last year or so. No new rock or anything.
