Well our jet black true perc female is finally spawning today. We'll try to raise them and see what color the babies end up. The male is normal color. I know ORA says they will come out with rotten color, but I"m gonna try anyways since this female is so extraordinarily black. Here is an old photo to show you the parent colors.
