Don't know much about genetics, but I have a male Sciaenochromis fryeri (blue body, white blaze) breeding with a female Pseudotropheus aurora (blue body, yellow belly) that I'm crossing trying to get all three features (blue body, yellow belly, white blaze on head/dorsal) First batch are 2.5 months old and some starting to show blue body and other starting to show a black dorsal ridge (like the aurora female). Will wait to get some more color, then cull for features I want.
