I have never attempted breeding. And I never plan on it. I know it requires TONS of work. You'd need a 20 gallon long tank , another tank female fry tank, and numerous male fry 'jars', filtration systems, very small live food, oh and 100+ homes. I would leave it to the experts. If you really want to breed I would give guppies a try. They are very easy livebearers and come in many colors.
