The sexual maturity age of parent fish is 6 months. The male fish has bright body color and long dorsal fin and hip tip; The female fish is light in color and round in abdomen. The aquaculture water temperature is 26~27℃, and the water quality is neutral. Several aquatic plants are floating in a 50cm× 30cm× 30cm fish tank. The male fish spits foam next to the aquatic plants to build a nest, and then pushes the female fish into the spawning nest to lay eggs. After spawning, the female fish should be fished out immediately. When the larvae can swim freely, take out the male fish. The female fish lays 300~400 eggs each time, with an interval of 10 day.
Feeding and management
China betta males are fighting, but they can still be kept in groups. But if you want to cultivate expressive individuals, you'd better choose excellent young males to raise them alone. Pay attention to adequate water, carefully filter the water and change the water regularly to keep the water clean. It is best to have dark bottom sand, a proper amount of plant mousse and floating aquatic plants, and the light should not be too strong. In order to cultivate the fighting ability of betta fish, we should train in front of the mirror for 2~3 times a day, each time for 5~ 10 minutes, so that betta fish can show off and fight with themselves in the mirror, and improve the expressive force of body color and fins. Don't feed for 2~3 days at the beginning of monoculture, and then feed blood worms, hamburgers and other feeds several times a day. The quantity shall be subject to eating within 5 minutes, and the excess feed and fish manure shall be removed in time.
