Correct me if i am wrong but don't Naso Tangs get their coloring when the mature? All the immature naso's i have seen are mostly a dull grey and only start to get the classic "make-up" on the forehead and lips etc when they mature.... and don't forget the streamers from their tail too....
Let me know if i am off base..... but wouldn't it be hard to give up a naso once it started to come into it's color and trade it for a immature individual....
