Bartletts, how can I tell the difference?

[KH971]

A friend of mine picked up 6 Bartletts and I am not sure which are males or females? They would be going into a 210 reef tank, would the males turn back to females or become subdominant males. Or just fight it out and die? Does anyone have pics of females and males?

One is definetley a male, then 2 are females, 3 are kind of between changing, I wonder what will happen to them? I have them in quarantine right now.

Look at the snout of the fish if the purple extends from the mouth to the dorsal fin its a male, if it stops before reaching the mouth its a female. Also a big male will have a thin vertical yellow stripe in the middle of its body.
