I've never read of anyone catching a mantis in a trap. Seems most people get them by removing the rock that it lives in. I have one in my 12g tank that hitched via TBS rock. He's eaten much of the clams and barnacles off the rock, and has re-arranged my peppermint shrimp (RIP). He's a wennerae, about 3.5" long, but doesn't bother with my royal gramma. I read that smashers don't bother with fish like spearers do. Anyhow, I do want to get him out of there, but am reluctant to take apart my rockscape to do it. If anyone's had success with a trap, would you let me know?
Thanks!
