(coral beauty, flame, bi-color and lemon peel)
The coral beauty and flame will be fine--you could do a pair of each, too. The bicolor is not only often non-reef-safe, but also non-living a lot of the time.
Flamebacks are B%^$*@ES! I wouldn't put them with anything except large angels and tangs. I've seen an inch-long specimen harass enormous 7-inch Caribbean butterflies--and had them running! There's one at work that's been in every tank in the fish system, too much of a butt-head to stay in any one for long! Avoid those and the similar "fireball angels". Frankly, while I had a cherub and loved him, he's in the same genus and very closely related, and I wouldn't trust those, either. But I only had mine with a large fourline wrasse, and they matched each other well.
Eiblii's can also be risky with corals, and especially clams and featherdusters. Of all the angels that I've seen nip coral, their favorites seem to be closed-brain-types, like Acan echinata, Platygyra, etc. Also zoanthids, which strangely I've seen more and more people whose rabbits have been eating zo's. Spotteds (orange-spot, black-spot), double-bar, and foxface seem to be the most common of the nibblers. Strange stuff.
