Congrats on the drop. It is time to do your best on preserving the fry and feeding them often enough to get lots of survivors. Both the creamsicle and the black females will receive the attention of your alpha male. They really don't care much about color at all. That means that the genetics of the fry will not be very predictable as long as both are kept in the same tank. Fry will take a full 4 weeks to develop starting at the time that the female uses a sperm packet to fertilize eggs inside her. In my own female's case, that was indeed 6 weeks with no males in the tank at the time. I cannot begin to predict how long it would take for a sexually active female to begin developing fry. They might well be along quicker than that for a new mating.
