1. Reason: The white film in the eyes of the red arowana may be that the water quality is too poor. If dirty things in the water enter the eyes of the red arowana, their eyes may also have white film.

2. Treatment: Breeders need to change water immediately to ensure clean water quality. However, the amount of water change should not be too large, and it should be controlled at one third of the total amount of water. At ordinary times, the filtration system should be opened frequently to slow down the deterioration of water quality.

1. Reason: Red Arowana has white membrane in its eyes, which may also be infected with bacteria. For example, it is not treated in time after injury around its eyes, or a large number of bacteria breed in the water, which will cause their eyes to be infected with bacteria.

2. Treatment: Breeders need to add some crude salt to the water in which they live, which can inhibit the growth of bacteria. The filter should also be turned on to slow down the deterioration of water quality.

1. Reason: Red Arowana may suffer from blindfolding because of white membrane in its eyes. The main cause of blindfolding is poor water quality or large environmental fluctuation. In the early stage of blindfolding, a white membrane will appear in their eyes.

2. Treatment: The breeder needs to raise the water temperature to 30 ℃ first, add some crude salt to the water properly, and finally turn on the oxygen pump to explode oxygen for the red arowana. If the effect is not obvious, the breeder needs to use Fish Eye Bao to give the red arowana a medicinal bath. Take a medicated bath once a day for 15-20 minutes each time.
