It is best to raise the male and female broodstock alone in the first half month of breeding, feed more fresh fish food, lay black and white pebbles at the bottom of the breeding box, plant broad-leaved aquatic plants, and set up an upside-down flowerpot.

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 monogamy, 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 swam for food for 2 days and fed with water.
