Thanks for the help

How large are they?

Going by the ventral pictures, I'd say they are all male, but I'm by no means an expert on sexing Hemiancistrus, nor do I feel certain about this.

They are around 15-16cm

Hi,

they all have quite massive pectoral fin rays (the first one).
That would suggest they are all male, I´m afraid..
