My personal opinion about hermits and corals are that the big'ger hermits (anything that's not "dwarf") do tend to develop a liking for corals at SOME stage or another in their stay in tanks. (personal experience - had the red-leg hermit - with blue/white spots on the legs).... My dwarf hermits do not chow anything coral related. Mostly only either detritus or algae (perhaps some food scraps if they can get to it).....
I do also know that some bigger hermit can kill fleshy LPS corals due to their legs ending in VERY sharp points - sometimes catching and dragging the LPS flesh, ending up tearing it.....
My first choice for starter corals would be any/all leather-type corals (sarcophyton/lobophyton, etc), Kenya Tree's (not dendronephtya), singularia, corrallimorphs (mushrooms), zoanthids, etc....
I would say give LPS a miss until you have far better understanding of their care.... Unless you have done a LOT of reading up on them and have kept some other corals already.
