Most Angels arent reef safe unless you get a Pygmy angel they are generally more reef safe. the larger angels arent so much but you can get lucky i have kept many large angles and have had great sucess with softies lps, sps.
Butterfly's arent reef safe either the only one i have had a ok experience with is the Copperband Butterfly. other than that all others WILL nip at corals.
Triggers that eat plankton ARE reef safe as in the blue mouth trigger and the niger trigger. all others will MOST LIKELY nip at corals.
REMEMBER its always a hit and miss with any fish. i know of clowns that eat corals. and wrasses that will destroy inverts and such. its a hit and miss but there are fish that will be easier than others.
