It looks like it has faint worming pattern under the eye, but I don't really see much on the cheek or across the bridge of the nose. My gut would tell me it's a female. It could also be a sub-dominant male but even then they usually have spotted cheeks/faces. I will say that when I bred notatus, it took the F1 males a long time to get their facial spots. Not sure why. So there's the potential it's also a male who's too young to have markings.
I'd almost be tempted to get them if you wanted to breed a fairy uncommon, undescribed species of severum. Hell, I'd even take them just because the male is going to be a very nice fish once it's settled and conditioned in a home aquarium.
