Question about lyretail anthias

[itsamyheff]

I have keep a male and female for about 2 years now. I recently added what I thought was a female, but it has the high fin on its back like my male has. Is it a male if it has the high fin? If so, will it turn female if the original male is more dominant. I know the female can change if there is no male, just did not know if it would be reverse. They are not fighting or anything, just asking.

I'm 99% sure its a one way process.

Yea, everything I have read stats female to male, until today. I read on wetwebmedia that if it is not completely changed to male it can suppress back to female. If that is true, what is the turning point? Both my male and female were the orange color. The male has the high fin and shows a purplish color when he his doing his dance above the female. Since adding the new guy, the original male's body has added some purplish color to the body and flashes alot more. The new guy only has the high fin and same color as the female. Since adding the new guy, the original male stays distant from the other two. Like I said, no fighting going on, I just want to make sure I have no issues coming.
