1. Reason: The blindfolding disease of map fish may be caused by untimely treatment after trauma, which leads to too many bacteria breeding around eyes. They are fierce in character and often fight. Once there is a fight, there will be injuries.

2. Solution: If the blindfold of map fish is not serious, the breeder only needs to change water, heat up and add salt to them. The first is to change water. Breeders need to change one third of the old water and turn on the filter to slow down the deterioration of water quality. This can prevent bacteria from growing again in water. The second is to raise the water temperature. Breeders need to use heating rods to raise the water temperature above 30 ℃. This can also kill most bacteria and speed up their recovery. Finally, add some crude salt to the water where they live, which can inhibit the growth of bacteria and avoid re-infection.

1. Reason: The blindfold disease of map fish may also be caused by malnutrition or eye mask injury. The breeder usually feeds too little animal feed or poor water quality, which will lead to their eye mask injury.

2. Solution: Breeders need to give them medicated baths with antibiotics first, and can also use medicated baths such as yellow powder, potassium permanganate and crude salt. If the blindfolded situation is serious, it is necessary to use special drugs for blindfolded diseases.
