I have 3 Yellows, 1 Sailfin, 1 Powder Blue, 1 Scopas and I will be adding an Orange Shoulder and a Purple Tang. I do recommend that you add them in 3's that way they aren't fighting so much. Currently they are all in a 92 gallon tank rubbing fins but soon they will be in the 380 so hopefully the Tang police won't pay me a visit.
