1. Water temperature: Arowana is a tropical fish, which likes a higher water temperature. It is necessary to keep the water temperature between 24-28 ℃ in the process of feeding at ordinary times. If conditions permit, you can use a heating rod to keep the water temperature constant.

2. Water quality: Arowana likes weak acidic soft water, and it is best to keep the PH value between 6.5 and 7.5 when rearing artificially. If the water quality is alkaline, you can expose it to the sun or add some big soda. If the feeding water quality is excellent, it can be boiled before use.

3. Feeding: Arowana prefers animal feed, and breeders should feed them more small fish, shrimp, loach, tadpoles, red worms, barley worms, Tenebrio molitor, lean meat, animal viscera and other foods.

4. Container: The body length of Arowana can reach 50-60 cm in adulthood, and the breeder should at least prepare a fish tank with a length of 120 cm, a width of 60 cm and a height of 70 cm for them.

1. Temperature difference: Arowana is sensitive to changes in the surrounding environment. If the temperature difference is too large, it may cause stress reaction. Breeders should keep the water temperature constant at ordinary times.

2. Change water: When changing water for Arowana, we should also pay attention to the fact that the amount of water for them should not be too large, and the amount of water for each change should be controlled at one quarter of the total amount of water.

3. Light: Arowana needs sufficient light to make its body color bright. When it is raised artificially, it is necessary to ensure that they have sufficient light. If there is no natural light, you can choose to install lamps instead.
