2. What should koi do if it doesn't eat1. Rest: Koi doesn't eat, which may be caused by environmental changes, and it hasn't adapted to the new environment, so it needs to rest for a period of time. Usually, koi fish that have just been bought will have such a situation. The rest time is usually three days, but some need longer, usually no more than one week, otherwise there will be fish problems.
2. Temperature rise: As a wide-temperature fish, although koi can adapt to lower water temperature, low temperature will still affect its vitality and appetite, and even make it not eat. In view of this situation, the best way is to raise the temperature properly. Usually, the feeding water temperature should exceed 18 ℃, so that the fish can grow healthily.
3. Cure diseases: When koi fish is sick, they often don't eat. What should be done at this time is to cure diseases first, and then feed them. Don't worry about koi starving to death, because fish are very hungry, and it doesn't matter if they don't eat for a month.
