1. Wait for it to recover by itself 1. Reason: Arowana may not open its mouth because they are not adapted to the new environment, and their adaptability to the environment is poor, so they will refuse to eat in the new environment. It may also be seasonal refusal to eat, which is common in spring and autumn in the north.
2, Solution: Breeders need to keep their surroundings stable and wait for them to recover on their own. If they don't adapt to the new environment, they can be covered with black cloth first to increase their sense of security and speed up their adaptation. If it is due to seasonal refusal to eat, breeders can keep the water temperature and water quality stable first.
2. Change water1. Reason: Arowana may not open its mouth because the water quality is too poor, and they have higher requirements for water quality. If there are more impurities in the water in which they live, they will also not eat.
2. Solution: Breeders need to change water immediately to keep the water clean. However, the amount of water change should not be too large, and it should be controlled at a quarter of the total amount of water. If conditions permit, it is best to increase the power of the filter to slow down the deterioration of water quality as much as possible.
3. Feeding gentamicin1. Reason: Arowana may suffer from diseases if it doesn't open its mouth, such as indigestion and enteritis. The main cause of this disease is improper feeding or unclean feeding.
2. Solution: If it is enteritis, gentamicin can be fed. If it is indigestion, probiotics can be fed. After the disease of Arowana is cured, the breeder can try to feed food again.
