Koi can generally live for two days without oxygen. If hypoxia lasts too long, koi may die. The survival time of koi without oxygen is mainly determined by the size of space and the number of fish raised. If the space is small, it can only survive for two days. If there are more fish, they can only survive for a few hours without oxygen. However, if the feeding density is very low and the water can be changed frequently, you can try to feed without oxygen.
How long can koi live without oxygen and how to play oxygen science 1. How long can koi live without oxygen

If koi live in a large space, it will last about two days without oxygen. Nowadays, many people like to raise ornamental fish in the same fish tank, which looks beautiful. However, each kind of fish has different requirements on water quality and different dissolved oxygen in water, so even if it is beautiful, don't raise it together.

I believe many people see a situation when raising koi. If koi is raised with many fish, koi will survive for several hours when it goes down to the tank. This is because there are too many fish and the dissolved oxygen in the water is not enough for them to breathe, so it is difficult to survive.

2. How to oxygenate koi fish

If there are not many koi fish in the family, you don't need to oxygenate all the time, but if you raise a lot of fish, it is best to supply oxygen 24 hours a day. In daily life, many people should have seen koi sometimes float on their heads, which means that koi is deprived of oxygen, so it is necessary to turn on the oxygen pump immediately.

Usually, it is easier to lack oxygen at night than during the day, and in summer, because of the high temperature, the metabolism of koi fish will accelerate, so the demand for oxygen will increase, and it is easy to lack oxygen at this time. Therefore, in order to ensure the safety and health of koi, it is best to take oxygen all day.
