I have a 90 gallon sps reef with acros, montiporas, and other sps. I also have 1 2.5" purple tang and 2 1" ocellaris clowns. I'm looking to add either a small regal angel or a Genicanthus watanabei angel and a fairy wrasse. I have heard that both angels are reef safe, anyone had experiences with either in sps tanks? Does anyone know how big the watanabei angel gets? I know the regals get kind of big, but would a small one be ok for a year or two until i get a larger tank? If anyone has had success with regals, what have you been feeding? Any thought on the commercial foods that contain sponges?
