Chevrons get a bit large too, 11 inches
I myself like the koles, as jwt had mentioned, and I feel taht anyone who has never actually seen one, should not judge them by their pics. I do admit many fish are not done jsutice by their pics, but IMO a pic of a kole vs a real look is like comparing quazimoto to Claudia Schiffer. They are done much more harm by theeir pics than about any other speces I have seen.
Get the koles, and IMO, if you cna find one,(this is difficult) look at the blue eyed species. Koles are underated(as jwt had mentioned) and more beautiful than i had expected( I now have one). Hearty and smaller, not to mention one of the 2 most docile tangs we have available.
