Wayne,
I saw the word Reef in there. I recently removed two female flames from my 90. They ate well, they would bicker very little. They would be in my tank now if not for the love of my corals. My experience was my Flame Angels nipping all of my SPS. I lost several frags. I can email you some pictures if you email me. Flame Angels look awesome in a aquarium. But they can be a menace to your SPS. The nipped at just about everything I had in tank as far as SPS. I do not want to burst your bubble. You may not have any problems, it may be just luck of the draw for me.
Wishing you the best of luck, which ever way you decide.
sincerely,
Ed
