[Regal]

I am being told in order for a Regal Angelfish to survive it should be in a reef aquarium. Has any one ever had any experience with one? What colours are best to be kept with one? I am not interested in doing an all out sps tank. Would the fish be ok in a mixed reef with leathers, ricordeas, acans, donuts, frogspawns and bubble coral? Clams?

Thank you.
