1. Abdominal enlargement: The most obvious symptom of Arowana after eating support is that its abdomen becomes larger. When they eat too full, their abdomen will become bulging and look the same as pregnancy. Although Arowana is a stomach fish, if they are fed too much food, they will also have the problem of eating support.

2. Reduced activity: Arowana will reduce their activity a lot after eating support, because they will become lazy after eating support, and will not continue foraging.

3. Refuse to eat: Arowana's appetite will become worse after eating. If eating is serious, they will refuse to eat.

1. Feeding frequency: The feeding frequency of Arowana needs to be determined according to their growth stage. Like Arowana in infancy, it is best to feed it 2-3 times a day. When they become adults, they can be fed once a day or once every two days instead.

2. Feeding amount: Although Arowana is a stomach fish, breeders should also pay attention to feeding amount. The Arowana in its infancy can be fed to 80% full every time. As an adult, it is enough to feed 70% at a time. This can ensure that they have sufficient activity and avoid indigestion.

3. Food choice: Arowana is a carnivorous fish, and breeders need to feed food according to their habits. The foods suitable for them are small fish, shrimp, loach, tadpoles, red worms, lean meat, animal viscera and so on.
