Just a note about the Flame Angel, their typical habitat is deeper than most coral fish. I forget if it's 25 feet or 25 meters, but this plays a role in the the way we the aquarist keep it. This is one of the most beautiful fish and I've had 3 or 4 in my own tanks. However, I kept losing them and approached an adjunct professor at my old university's Marine Sciences department who specialized in tropical fish. He told me that certain species, such a the Flame Angel require larger/deeper tanks that simulate the deeper pressures that one finds in their natural habitat. Could they exist at shallower depths, sure, but not thrive. I've never found this information documented anywhere, but this guy is smart and I trust his advice! So I stopped buying Flame Angels until the day I buy my house and build my mega tank!
