I have many types of hermits from Red and Blue legged, Halloween, scarlet, some orangy pale type and a dark, almost spotted one. NONE have ever gone after my corals other than picking at stuff on the stoney part (algae etc). I even have some sit in my pagoda cup keeping it clean. My Haloween is large (lives in a conch shell) and other than moving some things around, doesn't do anything bad.
