Yours look more like this bv on the left on top of the wood, anal has a little muscle but still a female.

The bv you referred to as female, can we see better side picture. I say you have a prime example of a female with the fish next to it on the dw. You have to remember only males will develop the muscular anal fin, it's used to catch the eggs. Females have no use for the muscle. Would make no sense for them to evolve with it.

Flint town!
I don't know much about the sexing thing I thought the width or thickness of the fin is what you go by. But you could have a small thin fin and if the base is very muscular its a male? Both my dels have a very thin fin but the base on one is very muscular ill try getting pics too.
