1. Water temperature: Arowana is tropical fish and likes higher water temperature. During artificial breeding, it is necessary to keep the water temperature between 28-30 ℃. If conditions permit, it is best to install a heating rod to keep the water temperature constant.

2. Water quality: Arowana prefers weakly acidic water, and it is best for breeders to adjust the PH value to 6.5-7.5. They like clean and refreshing water quality, and it is best for breeders to change water once every 3-5 days, and the amount of water changed each time should be controlled at one quarter of the total water quantity.

3. Feeding: Arowana likes animal feed, and breeders can feed them more live bait, such as small fish, shrimp, loach, tadpoles, water fleas and so on. You can also feed some red worms, protein worms, Tenebrio molitor, lean meat, animal viscera, etc. The nutritional content of these foods is relatively high, which can provide sufficient nutrition for the growth and development of Arowana.

4. Oxygen: Arowana is not a high oxygen-consuming fish, but they also need more oxygen than other fish. Breeders need to keep sufficient dissolved oxygen in water, so as to avoid hypoxia.

1. Sufficient space: Arowana is large in size, and breeders need to ensure sufficient living space in the process of breeding. In this way, arowana can grow and develop better.

2. Reasonable feeding: The feeding frequency of arowana is different at different stages and at different water temperatures. Breeders need to decide the feeding frequency according to their actual situation and eating state.
