ID n Sexing these 2 similar hypans

[Tuestar]

Hi, in need of your knowledge, to ID n sexing the following 2 similar pleco.
Please pardon the dark pictures

[MatsP]

I think they are both female, based on the relatively narrow head where it joins the main body, and at least in the first fish, it's "wide at the hips". For determining ID, I'd say t a picture from the side of the fish (aka "Lateral view") would be a much better way to see what it really looks like, and seeing the whole fish with fins erect would be the best choice.

thanks guys will try a shot once they stable down, they seem to have white base and greyish stripes rather than black though

They look to be very similar to L399/400 to this untrained eye. Good luck.

The first couple of fish are, in my opinon, one of the Lower Xingu variants. I'm not good at their ID, so I can't make it closer than that.

The Zebra's: First one is almost certainly male. The second I'm a bit less sure - looks more male than female, but it's hard (at least for me) to say for sure.
