Does koi need oxygen in winter? Does it need to be fed?

Raising koi indoors usually requires oxygen in winter. If the breeding density is relatively high, it must be oxygenated. Because Koi has a large amount of activity and oxygen consumption. In addition, the indoor water temperature is high and the oxygen content in the fish tank is low, so it is better to use oxygen in winter. But you don't need oxygen for 24 hours, and you can turn off the oxygen pump at night. If you raise koi in an outdoor fish pond, you can do without oxygen in winter. Because the contact area between the fish pond and the air is very large, the water is generally not anoxic.

1. Does Koi need oxygen in winter?

1. Indoor: If it is raised indoors, the temperature can be controlled above 20 degrees, and it needs oxygen. Because of the high temperature, the activity of Koi will be greater, and the amount of oxygen needed will also increase. Many fish friends will keep koi indoors in winter, and control the temperature at about 25 degrees, so that they continue to grow. In this case, oxygen is needed.

2. Outdoor: The outdoor fish pond has a large area and generally does not need oxygen. Because the water does not need to be changed too frequently in winter, the circulating filtration system needs to be kept open, and the water can not be changed if it is not dirty. If the water surface is frozen, you need to cut a few holes to let oxygen into the fish pond, otherwise the koi will die of lack of oxygen.

2. Does Koi need to be fed in winter

? Koi needs to be fed in winter, but the amount of feeding depends on the water temperature. When the water temperature is about 15 degrees, it is most appropriate to feed in 3-5 minutes. When the water temperature is above 10 degrees, it is best to feed in 3 minutes. When the water temperature is below 10 degrees, it is best not to feed. Because the water temperature is too low, Koi will reduce or even stop activity, the body metabolism is slow, appetite is not high, so you can temporarily not eat.
