ok so i got some new shots hope this is better

orino

azul

you cant really tell from the pictures but for the orino looking at her from the side you can see like a small nub sticking down like how convict females are when they start breeding and i was wondering if this was the case with my bass or are they gona always be like that

are these pictures clear enough to sex the orino?
