Silver arowana has different body types and different food intake. If the body length of silver arowana is less than 15 cm, they can eat 2-4 small fish of 2-3 cm a day. If the silver arowana is 20 cm long, they can eat 3-5 small fish a day. If their body length can reach more than 30 cm, they can eat 5-6 small fish a day.

Although most arowana eat this amount, breeders don't have to follow the standard feeding amount. It depends on their feeding state and water temperature to determine the amount of feeding. In addition, although the nutritional content of small fish is relatively comprehensive, breeders can't only feed this kind of food for a long time, which easily leads to their single feeding habits.

Silver Arowana likes animal feed, and it is necessary to feed them more nutritious food when cultured artificially. Such as small fish, shrimp, loach, tadpoles, water fleas, water earthworms, lean meat, animal viscera and so on. These foods have sufficient nutrients, which can meet most of the nutrients needed in their growth and development. When they are adults, breeders can feed them with synthetic feed, which can ensure balanced nutrition.

Silver Arowana can be fed more frequently in its infancy, 2-3 times a day, and it can be fed 80% full each time. When they are adults, they can be fed 1-2 times a day, and each time they are fed to 70% full.
