I've bred several jewel species. They take large tanks, lots of cover and a high tolerance for ugly, brutal behaviour. I had one pair that signalled spawning when the female would appear with no tail/caudal fin. It would be gone, right down to the base. In a few weeks, it would grow back like new, something I have seen with other nasty fish. They heal well.
Then they'd spawn again and the brutality would go on again.
Most Cichlid fry are nondescript things, but jewel babies are actually cute. No one wants them, as
@Colin_T noted above. You can't give them away, even if you raise them to full colour. In nature, red is a warning colour, and it's only a few aquarists like us who ignore that. Their reputation is well established.
They're open spawning softwater fish that will adjust to moderately hard water. I would never keep them in a tank less than a metre on the front glass. Plus you need to have a second aquarium if the violence gets too extreme and one of them needs to be saved.
