Possible Mantis?
The WWM Crew, I have some problems with my 125 G reef tank (75 G sump). Recent deaths/disappearances include: 2 Purple Firefish, 1 Blood Shrimp, 1 Skunk Cleaner Shrimp, 10 Peppermint Shrimp, numerous hermit crabs (red & blue legged), and numerous snails. Also missing in action is my tiger pistol shrimp who is/was mated with a Blue Spotted Watchman Goby- although he has gone underground for long periods of time before. The goby seems to be in perfect health. I hear clicking noises at night- which could very well be my pistol, but I have a bad feeling that I have an unwelcome guest in my tank…
