A buddy of mine keeps an Achilles, with a Powder Blue, a yellow a mustard tang and a gem. The fish get along and dont fight. Is it because they are different shapes? The Achilles and the Powder seem to be from the same species.
Just got Achilles goldrim hybrid today! From DD. about 3inches in a 55gl QT now. I have 3 Achilles, powder blue , and a black spot tang in the same tank! All get alone fine! PBT is the boss but he is the largest!
