Get a red-lined wrasse (Halichoeres biocellatus) instead. Stays a little smaller, much more peaceful, and invert-friendly. Still absolutely gorgeous though, and super active. Not all wrasses are aggressive by any means; many are perfect community fish. This species does require a sandbed to sleep in at night though.
if you’re insistent on a dwarf angel, you need to know that any type of dwarf angel can nip at corals. For every coral beauty owner who says theirs was a “model citizen” there is another whose coral beauty was great for months or years until it tried a bite of an LPS and then realized it tastes like candy to them. I’ve got a flame angel and it’s my favorite fish. Absolutely stunning, super active swimmer, and spunky little personality. So much so that I’ve decided that if it develops a taste for a certain type of coral, I just won’t get that type of coral anymore.
