I personally had a turquoise jewel and a Hemichromis Bimaculatus pair that sadly never produced anything but eggs. Their main problem was the convict cichlids I had with em constantly bullying them. My female was a bit weird in the fact the she would only breed with males half her size. Always heard that the female would only breed with a male that was larger then herself. The Hemichromis Bimaculatus was the female btw.
