1. Reason: If there are food residues or feces in the water, but they are not treated in time, the water quality will deteriorate. At this time, a large number of harmful bacteria will grow in the water. Harmful bacteria invade the eyes of dragons, causing white fog-like substances to appear in their eyes. If it is not handled in time, it is likely to appear white flocs and suffer from white eye disease.
2. Treatment: If the eyes of the arowana become cloudy, it may be infected with tuberculosis bacteria. At this time, the sick arowana should be fished out of the fish tank in time and put into new water. Appropriate amount of coarse salt can be added to the old water to sterilize and disinfect, so as to prevent the bacteria in the old water from infecting healthy fish. For severely ill fish, antibiotics need to be added to the water to prevent bacterial infestation and alleviate the disease.
1. Reason: When the chlorine content in the water is too much and the water temperature is too low, they will produce chlorine poisoning. At this time, their eyes will also appear white floccule, suffering from white eye disease.
2. Treatment method: Change the water in time and raise the water temperature. When changing water, attention should be paid not to change too much water at a time, but to change about one third of the water at a time. The water temperature should also be properly raised to keep it at about 25 C.
