Out of my 2 female Pseudotropheus Socolofi that I bred about 3 (out of 50+) were half black. I noticed this very early in their development, about the same time they started showing color (1/4"), they are now 1"+. Is this some type of melanistic color morph?
Here are some very bad pics but you get the point.
