I'll add my vote for the Regal angel, particularly the Red Sea/Indian Ocean color form. I've had one for 2 1/2 years in my 180 gal reef aquarium. My favorite fish! I would add that they are difficult but not impossible to get to feed.
The Queen angel is gorgeous too. As is the Blueface, Emperor, Conspicuous, Bluelined, Koran, Flame, Lemonpeel, etc....
