Just as an update: I did putthem all together and also added small caves where only the smaller ones fit inside. I think it's all fine at the moment.
Thank you for your comments.

Hi all,

as you can see in my last post I probably have four big Hypancistrus contradens males (around 12cm). Now I got three more, but smaller ones with 5cm with hopefully one or two females :d . At the moment I'm having the smaller ones separated from the others in a 60l tank. Now I'm thinking ...

Hello everyone,

I wanted to ask for help with sexing my Hypancistrus contradens. They are around 12cm each. By body shape I would think about all female, but by looking at their fins they look like all males. Maybe someone can help me :)

Greetings,
Tobi
