So will it be the dominant one
How are they with your LPS's
they are fine with my LPS as a matter of fact they dont bother any of the coral at all but are hell on snails . I have a Desjardin's Sailfin Tang & a Pacific Red Sea Sailfin Tang and the Desjardin's Sailfin was the king and they were 2 of the last Tangs introduced to the tank . Forgot to mention they do all get along but the red seas are bigger then the yellows and the Blue ring is bigger then the red seas so SIZE MATTERS may come into play . Good luck
