Koi fish eats miscellaneous food and basically eats everything, so it is best to feed both animal food and plant food. When koi is just hatching, because it needs more nutrition to maintain metabolism in this period, it is best to feed more animal food, and high protein can well maintain the nutritional needs in this period.
When koi is an adult, the metabolism of koi is slow in this period, so feeding collocation can be biased towards plant food, and more plant food can be fed to maintain daily metabolism. In a word, feeding should not be single, because if koi is fed with one kind of food for a long time, koi is likely not to eat.
2. The correct feeding time of koi fishThe feeding time of koi fish is adjusted according to the water temperature. The suitable water temperature of koi fish is between 22 ℃ and 27 ℃. At this time, it is usually fed twice a day, once at 10 am and once at 3 pm. When the water temperature is lower than 18 ℃, it is usually fed once a day. The metabolism of koi fish in low temperature environment will become much slower, so if it is fed too much, it will cause them to support. When the water temperature is higher than 27 ℃, you can't feed too much. Koi generally eats very little at this time, so you can feed it once every two days.
