Koi is not a nocturnal fish, so it won't move to eat at night. Feeding at this time will lead to an increase in residual bait, thus polluting the water environment. In addition, the feeding of fish must be regular, which is helpful to its growth and health. If the feeding cannot be fixed regularly and quantitatively, the fish will easily get sick. Usually, feeding should be done during the day, two or three times a day, don't feed too much every time, and clean up the residual bait in time.

1. Pay attention to time: When feeding koi fish, we should pay attention to time first. Usually, it is fed during the day. Because it needs to be fed two or three times a day, it is necessary to do a good job at intervals, usually once in the morning, noon and afternoon. If it is an adult fish and its size is relatively large, it can also be fed once a day, so it is best to feed it at noon.

2, pay attention to food intake: Koi has a large appetite and is gluttonous. Because it has no stomach, it will hardly be full, and it will always eat as long as it is fed, but it is not good for its growth and health, so we should pay attention to controlling food intake. Usually, after each feeding, it is enough to ensure that the fish are eaten within 3-5 minutes.

3. Pay attention to cleaning: If there are too many residual baits in the water, it will pollute the water environment and cause certain harm to fish, so it needs to be cleaned in time. Usually, when changing water, you can pull out the residual bait under the water, and you can also raise some cold water tool fish, but you must coexist harmoniously with koi to avoid fighting.
