It is normal for the newly bought arowana to don't eat after returning home, because they have just arrived in a new environment and will feel unwell. And they will feel fear and tension in strange environment, so it is very normal for them not to eat. When arowana doesn't eat, the breeder should first keep the surrounding environment quiet, don't talk loudly, don't suddenly appear around the fish tank, and don't stand in front of the fish tank to observe them all the time. It is also necessary to ensure the stability of their living environment and avoid the situation that the temperature difference is too large and the water quality fluctuates greatly. After a few days of adaptation, their mental state is somewhat relieved, and breeders can try to feed some food. If they don't eat, the breeder will have to wait a few more days.

Arowana is carnivorous, and there are many kinds of food they can eat. Usually, small fish and shrimp can be used as staple food to feed. Then it is matched with some insects, such as cockroaches, frogs, mantises, scorpions, etc. However, insects are easy to carry bacteria, so breeders need to disinfect them carefully before feeding them. It can also be matched with some insects, such as red worms, bread worms, yellow mealworms, centipedes and so on. When Arowana is an adult, it can be matched with some special synthetic feed, which can ensure balanced nutrition.
