I agree, if you are going to let the parents raise them then don't look. It might spook them. Pike cichlids are generally considered some of the best parents in the cichlid world, so I would lean towards leaving them unless the pair is just causing too much havoc in the tank.
If I remember right, Cr. marmorata parental care lasted six months, which is the longest of any cichlid species I've read about/seen.
