Naso Elegans/Lituratus/Unicornis Male or Female

[Genera]

Naso Unicornis - Naso Lituratus - Naso Elegans
The males of these species have streamers on their tails and the females don't correct? Is this a definite way to sex the fish and are there any other visible differences between males and females?

so i figured this would be a clear cut answer, but i started looking around, and it appears it is not. most of the things i am reading say streamers "usually" indicate a male, but i haven't been able to track down and hard information on sexual dimorphism in genus Naso.

now i'm interested... following along.

Is it possible to take a fish somewhere to have DNA testing done to determine it's sex? Also add Naso Vlamingii to this list.

I have always been told streamers mean males but DD sold a 3.5-4" without streamers and claimed it was a male so this just further confused me

I someone ask me a very similar question recently, and couldn't answer it. "How do you tell the sex before they are big enough to display streamers". I.E. "how do I avoid buying two females"
