Sunfish mainly feed on rotifers, cladocerans, copepods and other zooplankton: when the body length is 5-6cm, they can also feed on water, terrestrial insects, crayfish, organic debris, etc. ;

Hybrid sunfish in the adult stage mainly feed on aquatic plants, large zooplankton, benthic organisms, and small fish and shrimps. Under artificial breeding conditions, they like to eat bran, various cakes, duckweed, bulk and granular compound feeds, attached algae, various animal offal, small fish and shrimp.

Under artificial breeding conditions, animal feed such as chilled fish or artificial compound feed can be fed to replace natural feed. Sunfish is a middle-pelagic fish and will not be affected by feed that sinks to the bottom during acclimation. Feeding, so when feeding compound feed, it must be done in small amounts and many times. Because of its small diameter, the compound feed should be in powder or particulate form.

Spray the entire pond during acclimatization, and then replenish zooplankton. As domestication progresses, the amount of compound feed is gradually increased and the amount of zooplankton is gradually reduced, and finally they are completely acclimated to eat compound feed.

Extended information:

Yang fish often inhabit the middle and lower layers of water, live in clusters on larger water surfaces, especially where aquatic plants are thick, and overwinter in deep water in winter. It is not good at jumping, but when it finds bait on the water surface, it will quickly swim up to the water surface, eat the bait, and immediately turn around. At this time, the tail is exposed to the water surface, and there is a sound of slapping the water surface.

Mature male fish look for places with small gravel or sand on the bottom. They use their tail fins to swing and their bodies to twist powerfully to dig out the sand and gravel to form a circular nest as a place to lay eggs. The size depends on the size of the nest. The individual fish varies. Then, the male fish will stay in the nest or around the nest. When a female fish swims by, he will chase her fiercely and drive the female into the nest.

After the mature female fish enters the nest, she swims sideways along the inner wall of the nest. The male and female fish gradually approach each other in the nest to lay eggs and ejaculate. The eggs are laid multiple times and stick to sand and gravel. The female fish leaves the nest after laying eggs, while the male fish stays in the nest until the fry hatch and can swim horizontally.
