1. Reason: Arowana lying on the tank may be caused by the fluctuation of the surrounding environment. For example, when they change to a new environment, they will lie on the tank. In addition, they are very sensitive to environmental changes. If the amount of water changed is too large or the water temperature is too low, they will feel uncomfortable.

2. Treatment: If it is because of changing the new environment, the breeder needs to keep the surrounding environment quiet and stable, and wait for the arowana to adapt itself. If the water temperature or water quality changes too much, the breeder needs to keep the water temperature between 24-26 ℃ and the PH value between 6.5-7.5, and stop changing the water until the arowana recovers.

1. Reason: Arowana may also lie prone because of illness, and common blindfolding, water mold and enteritis will cause them to lie prone.
