I was reading this thread and it got me wondering about my tank. I have had many fish come up missing and have tons of empty snail shells lying around. Once in a while soon after the lights go out at night I will hear a clicking sound. Could I have a mantis shrimp? My tank has been up for years and I have never seen one or a molt from one. I have several peppermint shrimp and a pearly jawfish that have been untouched. What do yo think?
Thanks
Joe
