1. Reason: The convex eye of arowana may be caused by the old water quality, mainly because the nitrite content in water is relatively high, so their eyes will be infected, resulting in convex eye disease.
2. Solution: Breeders need to change water immediately to ensure that the water quality they live in is clean and fresh. It is also necessary to open the filter to slow down the deterioration of water quality and reduce the nitrite content in water.
2. Change the fed food1. Reason: Arowana's bulging eyes may also be due to the high protein content of the fed food, the large size of Arowana, and the decrease of their activity in the fish tank, so fat accumulation and bulging eyes will occur.
2. Solution: Breeders need to replace them with foods with low protein content and install a wave-making pump to increase their activity.
3. Apply anti-inflammatory drugs1. Reason: Arowana's convex eyes may also be caused by post-traumatic infection. When the eyes of Arowana are injured, it is easy to be infected with bacteria, resulting in eyeball infection.
2. Solution: Breeders need to change water immediately to avoid bacteria breeding. Arowana should also be fished out and smeared around their eyes to prevent wound infection. It is best to drop some anti-inflammatory eye drops into the eyes to speed up their recovery.
