Mantis shrimp can be with coral colonies usually but especially smashers will move small rocks and possibly frags around. If you have kept frags you know they can die easy if they get knocked over and you don't notice for a bit so if you keep them with any coral you want it to be well established so they can't move it. I wouldn't do lps or sps though i don't think they would bother it. Soft corals on large rocks should be fine.

Small ones can't but for big ones acrylic tanks are recomended. Some people will put a acrylic sheet under their substrate though a mantis shrimp shouldn't be able to break an appropriatly sized tank. Mines in a 10g sump. For their size they do have pletny of power. Mine has hollowed out a solid rock for his burrow.
so he's afraid of u huh?
Mine likes to roam around the tank often, maybe ur feeding him too often, have u tried hermit crabs for him to venture out and capture?
