I recently bought some florida liverock, and I caught 5 mantis shrimp from the rock by trapping and the suction method (it actually wasn't to hard as long as you sit and watch patiently). I think I got them all, as I haven't seen anymore, but I still hear an ocassional clicking noise coming from the tank. Do other liverock hitchhikers make clicking noises such as crabs or mollusks etc.. or do I probably have more mantis that I just haven't seen yet?
Thanks,
