Koi can live for about two days without oxygen pump. Koi is a large ornamental fish, and its oxygen consumption is very high. If there is no oxygen pump, it often will not live for too long. If you are raised artificially, you must ensure sufficient oxygen. If you are raised in a fish pond, you can raise the water level, so that if there is more water, oxygen will naturally be enough. If you use a fish tank, you must ensure that there is enough space in the fish tank, and then put the air head of the air pump into it.

1, which is beneficial to breathing: The primary benefit of oxygenation is to help fish breathe, because fish live in water and need a certain amount of oxygen. If the dissolved oxygen is too low, it will lead to oxygen deficiency and even affect their lives, so oxygenation is still necessary.

2. Maintain water quality: There is sufficient oxygen in the water body, which is helpful to maintain water quality. On the one hand, it can promote the reproduction of nitrifying bacteria, so as to better transform ammonia nitrogen and avoid fish being poisoned. On the other hand, it can also inhibit the growth of anaerobic bacteria, which also has a certain purification effect on water.

3, promote growth: Oxygen can promote metabolism, so the growth rate of fish will be accelerated when dissolved oxygen is sufficient. Moreover, fish also need more oxygen in the digestion process, and with some daily consumption, there are many benefits of supplying oxygen to them.
