I've never had an aggressive female in this species. I find the males to be less aggressive than other Melanochromis spp. I breed both chipokae and auratus and the chipoke fry are definately far deeper in the body - and more solid than auratus. Chipokae body depth is close to half as deep again as the auratus - at least up until 4cm size. They also grow much faster than auratus from babies up until 6cm.
