Not an expert and there was no need for your little outburst. Not everyone does everything you know, but I found this with a quick google. I hope it helps.
This is why it is risky buying a "breeding" pair. Fish don't mate for life, and often just the move will break the pair bond. Central American Cichlids are much easier to breed when they are young and not fully grown. Serious breeders can appreciate your frustration. One of the most common ways is to put a hole in the egg crate separator that is big enough for the female to escape, but too small for the male to enter. Put your substrate of slate or rock right near this opening, on the female's side, they can breed succssfully through the egg crate, without trashing each other.
Also consider it takes some time for them to get settled, moving fish can really disrupt them, and often they don't breed again for 6 months or more. So, don't give up!
