I bred these a couple times a long time ago. Just feed them well and raise the temperature, around 80 should do it. The male does use plants in his bubblenest, so you might want to have those around. Also, make sure the female has someplace to get out of sight in case they breed while you're not around. Good luck. . . . and let me know if you get any fry. I'd like to breed these again, but I can never find females anymore.
