Nah only warns them. Now my big (bullseye) one i can't say for sure. He constantly moves in the shadows around the tank and is constantly snapping. I do have a few snail shells piled up too. Lol.
I don't think you'd hear a Matis shrimp or a pistol shrimp TBO. I have a pistol and don't hear anything. Have you ever watched a video on the mantis shrimp? There very interesting.

Found my mantis in the rockwork about mid tank level. Had a series of caves and paths it hunted.
If he knows which rock it is its good cuz you can remove it and either freshwater dip it or as I did many moons ago obliterate it with a hammer and caught the mantis and re-homed it to a friend.
Remove rock and dip it into freshwater in a bucket. Should exit on its own. As I said I just smashed my rock with a hammer and when it broke into rubble it had no where to hide.
Yeah I know which rock it is just how to get him out?
