The breeding water is weakly acidic, and the water temperature is 25~26℃. The male to female ratio is 1 : 1. Both males and females will have rounded houses after half a month, usually laying eggs in the early morning. The marriage of this fish strictly adheres to the “monogamy” system, and no third male fish is allowed to intervene, otherwise the two males will be injured when they fight, so be careful when pairing. The fish has the habit of protecting eggs and generally does not eat its eggs by itself. The fertilized eggs hatched in 2 days, and then foraged for food after 2 days of flat swimming, and fed the “shuishui”. It is worth noting that the mortality rate of juveniles is high at 2 weeks, and nutrition must be strengthened. Juveniles are dark in color. After 8 weeks, the caudal fins turn red, and each fin is bordered with white. When grown, it becomes a black body and a red tail.
