:furious: OK so I thought I had determined that I had a mantis shrimp that hitchhiked on my rock that I got from my friend who owns a LFS. After the addition of 2 Yellow Tangs and 1 Yellow Coris Wrasse, all of which disappeared, I was confident that something was in my tank and killing my fish. However my Lawnmower Blenny and 2 Zebra Gobies are still alive and well. Anyway, the other weekend, I finally had some spare time and decided to take all my live rock out and find the culprit. I needed to do a water change on my tank anyway, so I decided to just drain the water into a bin that I had then take out each piece of rock and inspect it using a flashlight to look into all the holes I could find. After a long process I never found the shrimp or anything else unusual. I was so frustrated after this long process and coming up short. So I decided that I would put my rock back into my tank but to not rest any of the rock along the sides of my tank. That way, if I hear the tapping/clicking (which sounds like it was tapping on the tank itself) I can see all around the tank to see what is causing this tapping/clicking noise. The past few days I have heard the tapping/clicking sound. I have gotten off of my couch and stood at the tank looking on the sides and the back of the tank, only to see nothing. Yesterday, I was just standing in front of my tank just looking at it, and I heard the tapping/clicking sound. As I was looking around the tank, I would hear the tapping/clicking sound, but never saw anything. I am at a complete loss here. I have no idea what to do. I do not want to go get more fish for them to just be killed. But maybe it was something else. Maybe all 3 of the fish that disappeared, all died from stress or something that had nothing to do with another fish/shrimp/or whatever. Then after they dies behind the rocks, my cleanup crew came in and "cleaned up the mess". Any input on this would be greatly appreciated. I have tried everything to try and catch the supposed mantis shrimp, nothing has worked.
