In my 125 g tank, I have a Yellow Tang, Hippo Tang and Sail Fin Tang. My LFS has a beautiful Kole Tang he got in on Tuesday. Would this be ok to add? Other livestock are 3 Chromis, 1 Pygmy Angel, 1 Cleaner Wrasse, 2 Clownfish, 1 Anthias, 2 Diamond Spot Gobies, 1 Cleaner Shrimp and 1 Peppermint Shrimp. There is no aggression in tank.
