The difference between normal water exchange is that the water exchange interval needs to be shortened at this time, basically once or twice a day, so as to improve the water quality most quickly.
In addition to changing the water, it is also necessary to properly heat the fish tank. Usually, the water temperature should be raised by about 2 degrees Celsius, which can stimulate the fish, accelerate its metabolism and improve its resistance. It should be noted that after the fish recover, the temperature needs to be lowered back in time, otherwise it will also affect the healthy growth of the fish.
After changing the water and heating up, the next step is to add salt. Usually, freshwater fish do not need to use salt, at this time, the role of salt changes the osmotic pressure of the water body, thereby reducing the invasion of pathogens into the fish body with the water. Use more coarse salt, must not contain iodine, otherwise it will affect the health of fish.
Usually blindfold condition is not serious, rely on the above three steps can be effective treatment, but if the situation is serious, you need to carry out medicinal bath. General drugs with methylene blue or malachite green, the drug in accordance with the instructions into the tank, every few days after the water to fill a little medicine, so repeatedly until the fish recovery so far.
