koi fish usually needs to be fed once or twice a day.

The most suitable temperature for living in koi fish is 2-27 degrees Celsius, and the breeder can feed the fish 3-4 times a day, and ensure that the fish are eaten within 5 minutes each time. However, in hot summer or cold winter, breeders should pay attention to feeding, and try to ensure that it is about 1-2 times a day, and the amount of feeding should not be too much, so as to ensure that koi fish can finish eating within 1 minutes, and there is no feed residue in the fish tank.

If the water quality in koi fish is not good, or koi fish can't eat it, then it is necessary to stop feeding koi fish. Koi fish should not be fed too much every time, otherwise it is difficult for koi fish to digest food. At ordinary times, koi fish can be fed some small fish and shrimp, high-grade feed and other foods, which can make the color of koi fish more vivid.

Points for attention in feeding koi fish:

1. Don't put koi fish in the new tank too soon, and koi fish can be put in at least the third day. Putting koi fish in the new tank too early will only do harm rather than benefit.

2. Don't overfeed, just be eight points full, and don't overfeed for fear that koi fish won't be full, because the probability of fish starving in koi fish is too low. If the novice has not fully mastered the water quality and is not clear about the influence of excreta and food residues on the water quality, feeding once a day is enough.

3. Under the condition of good filtration, it is very important not to wash it too often, and the continuous operation of the filter is a great guarantee to ensure the health of koi fish. If all the filter materials are replaced or cleaned too cleanly, it will not achieve its due function.
