Most cichlid eggs look similar whether JD, or any Central American cichlid.
Above is a Nosferatu bartoni with eggs on a log, although creme colored, they will slightly match the color of what they are placed on. The white ones are infertile, there are always a few like that.
After they hatch the parents will hide the wrigglers somewhere in the tank, sometimes they dig pits, sometimes under rocks.
In the wriggler stage they don't eat, but use up nutrients in their yolk sac.
They tend to amass together, sometimes in a pile.
When they start swimming in a school, you need to have food ready, and the more times you can feed per day the better. I hatch brine shrimp, and try to feed 4-6 times per day. I also let as much algae grow in the tank for them to graze on, in between meals.
You can also pipette (or use a turkey baster) to send clouds of frapped food in tank water into the school. I process thawed peas, flake, even eggs yolk with tank water and shoot it into the school of fry.
as fry grow less and less processing is needed
