You have a really uncommon fish there. I've seen it at a wholesale place here, but have never kept it. What I've been told is about what you'd find online - open spawners, precocious spawners, good broodcare, warmer water (26ish). That's pretty generic for a Cichlid from there, but the only person I know who has had them spawn found them to be pretty standard in their behaviour and needs. He really liked them though. If he had raised fry, I probably would have bought some based on his enthusiasm for the species.
For how to, I'd use a 3ft, one m tank with a single pair and no other Cichlids. The water would be soft. I think then, it would just be a matter of patience.
