If it is a newly born arowana, the breeder can choose to use the eggs of abundant shrimp, water fleas, chopped red worms, etc., because these foods are easy to digest and have high nutritional content. It is also suitable for small arowana to open its mouth. If it is a developing arowana or an adult arowana, the breeder can feed them some small fish, shrimp, centipede, barley worm, yellow mealworm and so on. These foods are preferred by Arowana, and live bait can also arouse Arowana's interest in preying, so that they can open their mouths to eat faster.

The feeding frequency of Arowana needs to be determined according to their growth stages, and the feeding frequency is different at different stages.

Under normal circumstances, arowana in its infancy needs to be fed twice a day, and the amount of each feeding can be eaten within 5 minutes. Because the arowana in its infancy has a high demand for food and nutrition, but its appetite and digestion ability are not strong, the breeder needs to feed it several times in a small amount. This can not only avoid indigestion, but also speed up their digestion and absorption of food.

When they reach adulthood, the frequency of feeding can be changed to once a day, and the amount of each feeding can be eaten within 10 minutes. Because when they are adults, they have a higher demand for food and nutrition, and their appetite will become larger. Therefore, the frequency of feeding by breeders can be reduced.
