Ah. Sorry i misread your post. I thought it was 2 photos of 1 fish with differences in lighting and aspect accounting for the variations between the photos.
It could be female. The fins look a little more rounded, there does appear to be a line. Cant really see the body shape though due to the head being more head on in the photo. But it looks a little more orange which would say male.
Extract from spruce fish if it helps with body and fin shape.
