1. Poor water quality: The main cause of Arowana blindfolding is poor water quality, and they have high requirements for water quality. If the living water quality is too poor, it is easy to cause bacterial infection. Moreover, their eyes are fragile, and bacteria can easily invade.

2. Bacterial infection: Arowana suffering from blindfolding may also be caused by eye injury. If they are not treated in time after injury around their eyes, they are easily infected with tuberculosis and Vibrio. These germs can cause Arowana to be blindfolded.

3, nitrogen into the body: If the water in which arowana is raised contains more nitrogen, it will also lead to blindfold. Arowana blindfolding is not obvious in the early stage, but in the later stage, their whole eyeballs will turn white. When artificially raising arowana, it is best to observe frequently, and treat them immediately once they are found sick.

The cure speed of Arowana blindfold is not very fast. If breeders want them to get better as soon as possible, they should use various treatment methods together.

First of all, breeders need to raise the water temperature to 32 ℃, because most of arowana blindfold diseases are caused by bacterial infection, and high temperature can kill most of the bacteria and inhibit the growth of bacteria. The second is to change the water immediately, but don't change it all, just change one third at a time. Finally, turn on the oxygen pump to ensure sufficient oxygen in the water.

Most blindfolded diseases are caused by the invasion of tuberculosis and Vibrio, and breeders can use fish eye treasure, potassium permanganate solution, gentamicin and other treatments. To speed up their recovery, gentamicin sulfate can be injected directly. However, it is best to use it less at the initial stage, about half of the dosage marked in the instruction manual.
