How can I tell if I have one?

I hear clicking from time to time, and I also have two fish that have not shown themselves for some time. I am really hoping that I have a pistol shrimp and that my missing Yellow Watchman Goby has just taken up with him and doesn't come out anymore. My Rainford Goby is also MIA, so I am begining to suspect that perhaps a mantis shrimp is in there killing stuff. I want to lure him out if possible and confirm my suspicions.

any updates to the fish?

You know what? I'm having the same exact problem! I hear clicking sounds periodically; and I mean--there's no mistakening it either. I thought maybe the dripping of the water into my sump is the reason but it doesn't seem right since the gravity feed into the T-inlet is completely submerged. My hogfish DIED...mysteriously! At first I thought it may have been my water quality but that's not possible; I have a yellow-eye kole tang in the same tank. And those things are less tolerant of high nitrates than the hogfish. It couldn't have just died.

At the same time, I've never seen the mantis shrimp either. How do I catch it if it is in fact a mantis shrimp?

setting out a bottle food trap may be the easiest way
