They have bred for me under normal conditions , some times after a water change . Just be patiant , It isn't dificult to get them to breed , It will happen , and happen over again once they get going . I think the Cichlid Addict said they would breed in a toilet bowl and if the temp was good I'd be inclined agree with him . Be patiant , before you know it you'll be trying to figure out how to get rid of the fry . Good Luck , and remember they may not get very big , but sure can act it .
