lol. I've bred 7 kinds of peacocks in the last couple of years; also have three OB peacocks in the community tank..... Still can't tell males from females for jack. 
From what I've seen, the only ways to tell are these:
-Vent them.
-Watch them do the dance to see who's grabbing eggs.
My guess is that you have a female, my friend.
