I would look at Live Aquaria and Bluezooaquatics and see if the fish are listed as “Reef Safe”. I have acropora, montipora, birds nests and pocillapora. I have a yellow tang, a powder brown tang, a kole tang, a blue chromis, an aptasia eating file fish, and a couple of reef safe wrasses. Also have had fire fish and Bengai cardinals. Nothing has bothered the coral. I would ask in the fish forum about when you narrow things down to specifics. I would think most gobies are good. Most tangs are good. Most chromis and damsels are good (of course, damsels can be horribly aggressive). Dart fish and cardinals are good. So you have quite a few options.
