For those of you that don't want the Mantis in your main tanks, I thought I would post my experience in removing them. I was able to remove one mantis by using a hypersalinity dip, but I dipped all my rocks and only one came off.
Best way to capture mantis EASY, find out what rock they are in and in what hole they spend most of their time. Buy a 50 cent bottle of seltzer water and remove the rock, hold over a bucket of mixed saltwater and squirt the seltzer in their hole with a turkey baster and the mantis will FLY out. I captured two of them in about 2 mins using this method. Removed two mantis that the hypersalinity dip did not find. Just make sure the seltzer water doesn't touch any life you want to keep. Mantis survive it no problem as they quickly drop into the bucket of saltwater. The rock will thank you being spared the hyper salinity dip(which I think was responsible for some of my tube coral croaking).
