I can't say which to get because we only have a coral beauty. I have to say this is my favorite fish that we have, he is always on the move and likes to play games with you, sort of like hide and seek. He will move into a cave and then look out of a small hole until you look at him and then he'll come out for awhile and then the game starts over. Very cool fish.
On a side note, it took him 8 days before he finally ate. He would go up to food like he was going to eat and then tail off at the last second. We tried every type of food we could think of, and we tried with and without garlic. Once he finally ate something, he is a eating machine now, eats everything we feed. Also, we have read and been told that the coral beauty is more reef safe than the flame angel. Good luck.
