1. Reason: Fish don't live in the right environment. In the process of feeding, the water quality is not clean, the water temperature is too high or too low, and the PH is not appropriate, which will bring harm to the health of fish. Living in such an environment for a long time, the immunity of fish will decline, leading to rotten tail disease. When the disease occurs, the tail of the fish will rot.
2. The treatment method is as follows: the water is changed immediately, the PH is adjusted between 5 and 7, and the optimum temperature is kept between 20 and 26 deg C. Let the fish live at the optimum temperature, which is conducive to its recovery. Oxytetracycline tablets are dissolved in water and medicated bath treatment is carried out on the rotten part of the fish tail. Medicated bath 10 to 20 minutes a day, about a week after the situation will improve.
1. Cause: The tail of the fish was injured due to fighting or improper transportation. After the injury, the wound was not disinfected and sterilized in time. Bacteria in the water adsorb on the wound, causing the wound to fail to heal, and the fish tail will begin to rot.
2. The treatment method is as follows: the rotten fish is isolated, and the fish body is soaked and washed by the potassium permanganate solution with low concentration. Then put the fish in clean water, warm the tank and add some coarse salt to prevent bacteria from breeding again. As long as the bacteria in the wound of the fish are killed, the wound of the tail will heal and the tail will not rot again. Repeat these operations every day until the wound at the tail of the fish is healed.
