It is best for map fish to feed 2-3 times a day. Their appetite is relatively large, and their digestive ability is relatively strong, so the amount of feeding needs to be larger. In their infancy, breeders can choose to feed them three times a day, and the feeding time can be the same as our breakfast, lunch and dinner, but pay attention to the feeding time at night, which cannot exceed 4 o'clock, otherwise it may cause indigestion. When they are adults, they can be fed twice a day. Feeding time can choose morning and evening, or morning and noon.

Map fish are large, so they eat a lot. When rearing artificially, it is necessary to decide the food to be fed according to their weight. Generally speaking, the food fed is most suitable for one tenth of their body weight. It can also be judged by the time of eating. Generally, the food fed can be eaten within 10 minutes.

Breeders can choose to feed map fish some animal feeds, because these feeds contain large protein and fat, which can meet most of the nutrients needed for their daily development. The animal feed suitable for them to eat is small fish, shrimp, loach, red worm, earthworm, cow heart, lean meat and so on.

In addition to animal feed, breeders should regularly match them with some plant feed to ensure their balanced nutrition. Plant feeds suitable for them include vegetables, fruits, moss, algae and so on. When map fish mature, they can also choose synthetic feed as their staple food. Synthetic feed is rich in nutrients and is not easy to pollute water quality.
