1. Reason: Arowana may not eat because it is in a new environment or frightened. Although Arowana is large, it is easy to be frightened. Moreover, they are sensitive to changes in the environment. If they change to a new environment, they will lie prone.

2. Solution: Breeders should ensure that the surrounding environment is quiet. If the fish tanks can be moved, it is best to transfer them to a quiet and dim environment, which can increase the sense of security of arowana and speed up their recovery.

1. Reason: Arowana does not eat in the tank. It may also be because the water temperature is too low. Arowana is a tropical fish and likes a higher water temperature. If the water temperature is too low, their appetite will decrease and their activity will decrease.

2. Solution: The breeder needs to slowly raise the water temperature to between 24-26 ℃, and use a heating rod to keep the water temperature constant. Wait for the arowana to adapt to the water temperature before trying to feed food.

1. Reason: Arowana does not eat in the tank because the water quality is too poor. Arowana has higher requirements for water quality. If the water quality of raising them is too poor, they will lie in the tank and do not eat.

2. Solution: Breeders need to change a small amount of water and turn on the filtration system to ensure clean and refreshing water quality. It is best to control the PH value between 6.5 and 7.5.

1. Reason: It is also possible that the arowana does not eat in the tank because of the large fluctuation of the environment, such as the large temperature difference between the new water and the old water, the large amount of water changed, and the different water quality between the new water and the old water.

2. Solution: If conditions permit, you can restore the environment to its original state. If it cannot be reduced, the water temperature can be kept between 24-26 ℃ and the PH value can be kept between 6.5-7.5. Then wait for the arowana to recover on its own.
