I bought a tank from a guy and took the LR out and put into an established 10 gallon on my desk just for the time being. Out of the corner of my eye I see something swim across the tank and into a rock formation. It was long and thin like a little wrasse but doubt its a fish and previous tank owner says he only had coral and a few crabs. I could swear I am now hearing a clicking sound emanating somewhere on my desk and its not my TMJ! Do mantis schrimp click?
