Treatment methods for Arowana sunken head:

1. Avoid being frightened. In daily feeding, we should try to avoid large and sudden changes in temperature, as well as the possibility of not adapting to the environment such as changing water and tank, or being frightened and violently swimming and hitting the tank, causing the fish's swim bladder to be injured and the fish to sink its head.

2. Physical fixation. It is still difficult to cure the sunken head of arowana caused by congenital imbalance. It can be maintained for a period of time through physical fixation.

3. Induced movement. Properly lure fish with sunken heads to feed, and reasonably control the switching time of the wave pump to provide a more spacious living environment for the arowana and promote the movement of the arowana.

4. Promote digestion. In daily life, the food you feed must be processed cleanly and the sharp parts must be removed to prevent the arowana from being unable to digest it and thus reduce the risk of diseases such as head sinking.

5. Improve water quality. When the water quality in which the arowana is kept deteriorates, it will also cause the arowana to sink its head. The water in the tank can be changed in time, a small amount of salt can be added for sterilization, and the temperature can be raised to 30 degrees.
