1. Water temperature: Arowana is tropical fish and likes higher water temperature. Artificial breeding of Arowana can keep the water temperature between 25-28 ℃.

2. Water quality: Arowana has high requirements on water quality. They like weak acidic soft water, and breeders need to keep the PH value between 6.5 and 7.5.

3. Change water: Arowana is sensitive to the change of water quality, and the frequency of changing water for them by breeders does not need to be too high. Under normal circumstances, it is ok to change the water once a week. The amount of water changed each time should not be too large, and it should be controlled at a quarter of the total amount of water.

4. Feeding: Arowana is a carnivorous fish, and it is necessary to feed them some highly nutritious and digestible foods in their infancy. For example, bumper shrimp, red worms, blood worms and so on. When they are adults, they can be fed some pellet feed, lean meat, animal viscera and so on.

1. Stable environment: Arowana is sensitive to the change of water temperature. During artificial breeding, it is necessary to keep the water temperature constant to avoid discomfort caused by too large temperature difference. In addition, when changing water, we should also pay attention to the temperature difference between new water and old water not exceeding 1 ℃. In addition, when changing water for Arowana, the PH value should be adjusted to be consistent with the old water, so as to avoid stress reaction caused by water quality fluctuation.

2. Reasonable feeding: Although Arowana is a stomach fish, the breeder feeds them too much food and is prone to indigestion. Breeders need to decide the feeding amount according to their eating status, so as to avoid enteritis and other problems.
