Well she's huge so I doubt she's a young male. Her body is very masculine, I agree.
How long are the ventrals? The two little fins infront of the anal fin. I can't see them, but even plakat males have long ventrals, so that's a good indication usually.
She's also got some faded stripes, young males and females have those.'of course if she's big I doubt she's young. Was she stressed out in the photo? sometimes males stripe up when stressed. If she always has them I'm pretty sure shes a girl.
The only time I ever got a female to flare was when I put a male infront of her. My girl has a short tiny beard, but it's still visible, nothing like a male's though.
