Huang Hao spawned at night or early morning after a thunderstorm. The broodstock first spits out a large amount of white foam outside its cave as a nest, and the female fish lays eggs in the foam. The number of eggs ranges from tens of grains to two to three hundred grains. The eggs are large and round, and are yellow. If there are water plants, seedlings, and no strong wind at the spawning site, this foam nest can be maintained until the seedlings hatch. In case of strong winds or currents, eggs will sink into the water near the hole. During the spawning season, people can carefully search for the fertilized eggs of the nests along the fields and ditches in the paddy fields and collect them with a gauze net. The collected fertilized eggs were placed in pots and barrels to be incubated in the room. The water was changed 1 or 2 times a day, and the seedlings were filmed after 6 to 7 days. After 5 to 7 days of temporary feeding, the area of ​​water should be expanded according to the number of seedlings, and the cooked egg-yolk paste and zooplankton (water jellyfish) should be fed. When it grows to a size of more than 3 cm, it is transferred to the seedling pond.

Biology is mainly used for feeding leeches, fly maggots, and terrestrial maggots. Dianchi must be shaded during the hot season.
