The Arowana can turn on the lights for 8-12 hours every day. When they are in the wild, they like to live in the upper waters, although they can receive plenty of sunlight during the day and live in a bright environment. But as the sun sets, their living environment will also fall into darkness. When raising Arowana artificially, we should try our best to restore the wild environment, so it is ok to turn on the lights for 8-12 hours every day. Turning on the light for too long or too short will have a certain impact on their growth. If turning on the light for too long, it will affect their rest and lead to their inability to grow better. If you turn on the lights for a short time, you can't guarantee their bright body color. In addition, the schedule of Arowana is similar to that of human beings, so breeders can choose to turn on the lights during the day and turn off the lights at night.

Arowana can get oxygen for 3-5 hours every day. Although they have a large demand for oxygen, they don't need oxygen all day. Breeders can choose to explode oxygen for 3-5 hours every day to ensure sufficient dissolved oxygen in water.

You can also choose to reduce the amount of oxygen, and take a small amount of oxygen continuously for 6-8 hours every day. But at night, the oxygen pump needs to be turned off. Because Arowana will rest at night, the oxygenated water flow may affect their rest.
