Arowana Nile is generally large in size, so it is important to choose a suitable fish tank when breeding, otherwise it will affect their normal growth. The length of 1.2 meters, the width of 0.5 meters and the height of 0.7 meters are the minimum requirements for the space size of fish tanks. In addition, it is a universal truth to raise water before raising fish. Before raising fish, a complete nitrification system should be established in water to provide a favorable water environment for their growth. Generally speaking, it is not very difficult to raise them, so long as they are taken good care of, they can be taken good care of.

1. Water quality: Good water quality environment is one of the necessary conditions to ensure the healthy growth of Arowana niloticus. They like weakly acidic water quality. When feeding, it is recommended to control the pH value of water between 6.5 and 7.5 and the hardness of water between 3 and 12. Ensuring proper pH value and hardness of water body can help them grow better.

2. Water temperature: Because their origin is in tropical or subtropical areas, the requirements for temperature are still relatively high. It is best to control the water temperature between 28-30 ℃ during farming.

3. Water change: Regular and appropriate water change operation is a necessary condition to keep the water quality clean, so about one fifth of the water body needs to be changed every week. It should be noted that the new water used when changing water must be dried water, and the new water should be slowly injected into the old water, and it is best to ensure that the temperature difference does not exceed 2 ℃.

4. Feeding: The most suitable food for feeding them is small fish and shrimp. You can also feed some centipedes, frogs or barley worms as complementary food.
