Aequidens (your Acara) and Hemochrimis (Jewel) can't breed. In fact, they really shouldn't even share the same tank space. Blue Acara are a S Amer cichlid which inhabits still water areas. Jewels are African river cichlids, and prefer moving water. Their mannerisms are different, as are their dietary requirements. They may cohabitate fine for years, or you may suddenly have problems. Acaras aren't particularly aggressive, but Jewels can be nasty. IMO, rehome one or the other to a tank with similar species.
