Oxygen is used to raise fish in fish pots. The water contained in the fish basin itself is very limited, and the water is still very shallow, which means that it is easily affected by temperature. As the temperature rises, the dissolved oxygen in the water body will decrease, so if oxygen is not applied, the fish will easily lack oxygen. Oxygen pump is generally used to pump the air head into the fish basin, so that the fish can breathe freely, which is also helpful to its growth.

1. Koi: Koi is an active fish. Because of its vigorous vitality, it has a great demand for oxygen, so it needs to be oxygenated, otherwise it is easy to die of lack of oxygen. There are many varieties of this kind of fish, but they are mild by nature, easy to raise, and the requirements for water temperature are not high.

2. Arowana: As a common large ornamental fish, Arowana consumes a lot of oxygen, so it can't be raised without paying attention to oxygen. The body length of this kind of fish is about 40-50 cm, so it needs a bigger fish tank to raise it. Because of its fierce temperament, it is difficult to mix it.

3, Lohan: Lohan fish also prefers high dissolved oxygen environment. If dissolved oxygen is low, it is often difficult to feed. Usually, the water temperature should be kept at about 30 ℃, and the dissolved oxygen should be greater than 6 mg per liter. If the oxygen is insufficient, it needs to be oxygenated by oxygenation equipment.
