Black on Naso tang face

[Recty]

I've recently acquired a blonde Naso tang.

From pictures and RL experience of seeing other's Nasos, they always have a nice black color going from their dorsal fin down to their mouths, basically covering what I would consider the "forehead" of the fish.

Mine however is just a light gray there, barely darker than the regular gray sides of the fish... does this change to darker colors as the fish matures?

Mine is only about 5 inches long atm, slight streamers just starting to develop on the tail.

when i got mine she was only 2" she had a gray face too,

now it is still only 4" after a year and it developed the plack color on the face, it will come in time. does yours show streamers yet? mine still may turn out a male.

Slight streamers just starting to develop on the tail. Nothing major and I could be mistaken, but it looks to me like streamers are just starting.
