, after the fish got erect scale disease, need to give it to stop eating first, then use the salt water bath with lower concentration, soak time in 10-15 minutes, still can apply erythromycin ointment to the fish. This disease is mainly based on prevention, we must pay attention to changing water at ordinary times, keep the water quality clean, but also let it bask in the sun, but not too long, in order to avoid greater changes in temperature.
of leprosy? 1. The temperature difference is too large: If the temperature difference is too large when changing water, it is easy to cause fish to be stimulated, thus suffering from leprosy. This situation is generally not very common, and it is not a big problem, as long as the temperature is properly raised and kept constant, it will soon recover. When changing water daily, we should also pay attention to the temperature of new water and old water, and the difference should not exceed 1 ℃.
2. Fluctuation of water quality: Changing water too frequently will cause fluctuation of water quality, which will lead to fish suffering from leprosy. Therefore, it is necessary to control the frequency and amount of water change in peacetime, generally once a week, each water change should not exceed one third of the total amount of water, and do not change water violently.
3. Bacterial infection: In addition to frequent water changes, long-term non-change of water can also lead to fish scaly disease. This is mainly due to the deterioration of water quality and the proliferation of bacteria, which infect fish and make them sick. Therefore, in addition to changing water, we should also use drugs to sterilize and disinfect fish.
