I have 12 tangs. The Achilles is the main boss but it is smaller than the Fowleri and Blonde Naso. He won't really bother those two. He chases the powder blue everyday. The purple is probably next in line as far as agression goes.
Woah what size is the tank? DimensionsI have a huge Achilles, purple, powder blue, powder brown, blue, sohal and naso. All the naso’s I’ve ever had have been completely docile. All my tangs get along fairly well but will flare fins and do some circles from time to time. Most of the time they swim in a pack together. No real pecking order that I’ve noticed with the powder blue, powder brown, purple and sohal being equally dominant.
