With any fish addition its usually a roll of the dice. Other than a little squabbling now and then I really have not had a problem with any wrasses. I had all these living peacefully along with 3 tangs, 5 angels, 10 anthias and a few other misc. I say had because I lost my red velvet to jumping a while back and one of my exquisite disappear (had a pair). Even the one fish everyone tells people to not get, the six line, is a model citizen and bothers no one. Most of these are at the 1-1.5yr mark in tank and the sixline was actually the first in tank. Its just luck of the draw. Sometime soon some flames are coming to this tank too :D
