if the mouth of the fish is rotten? If the mouth of the fish is rotten, you need to change the water properly first. Don't change too much water each time, usually not more than one third of the total amount. After that, the water temperature should be raised and salt should be added appropriately. The concentration of salt is about three to five thousandths. If the fish does not recover, it needs to be treated with medicine. Yellow powder is usually used. Pour it into the fish tank and change the water every other day to see if there is any sign of recovery.
1. Change water regularly: If you want to prevent fish mouth rot, you should first pay attention to changing water at ordinary times. Usually, there is no fixed cycle for water change. According to the maintenance of water quality, it can be changed once every three days or once a week. The amount of water changed each time is about one quarter or one fifth, and the temperature before and after water change should remain unchanged.
2. Stabilize the water temperature: The rotten mouth of the fish may be stimulated, for example, the temperature difference is relatively large. In view of this situation, the best way to prevent it is to stabilize the water temperature, control the temperature within a specific range, and use heating rods to maintain a constant temperature, so as to prevent the fish from rotting their mouths.
3. Clean the bottom of the tank: If you do not pay attention to cleaning the fish tank at ordinary times, the dirt in the tank will decompose and pollute the water body, which will also lead to the rotten mouth of the fish. In the daily feeding process, it is necessary to clean up every other time, which can be done when changing water.
