INFORMATION ON KRIBENSIS CICHLIDS?

I would really like to buy a pair of KC to breed. I just want to know.. when the female lays her eggs and the male fertilizes them, how long will it be before the eggs hatch?.. And after they hatch do you have to separate the adults from the fry, or separate the adults from each other?.. If anyone could just answer those questions for me that would be great, thank you.
