Arowana is best monoculture, because they belong to large fish, and their body length can grow to 60-120 cm in adulthood. Although the size of artificial breeding will be smaller, it will generally be between 60 and 80 cm. If they are mixed with other fish, there may be insufficient space. Secondly, Arowana's character is fierce and aggressive. If they are mixed with other fish, they are likely to bite or kill other fish. Finally, arowana has high requirements on the environment. If too many fish are mixed, it may affect their living environment.

1. Water temperature: Arowana has high requirements for water temperature, and breeders need to keep the water temperature between 28-30 ℃ before they can live normally. Arowana is sensitive to environmental changes. If the water temperature in which they grow fluctuates, they will also have more discomfort.

2. Water quality: Arowana also has high requirements for water quality, and they like weak acidic soft water. It is best for breeders to keep the PH value between 6.5 and 7.5. They like clean and refreshing water, and breeders need to change the water once every three days. If there is a filter, you can change the water once a week.

3. Feeding: Arowana prefers some live bait. Breeders can feed them more small fish, shrimp and other foods, as well as some red worms, bread worms, yellow mealworms, lean meat, animal viscera and so on.
