If you give fish a medicine bath, you need to choose the concentration and time of the medicine bath according to the condition. Generally, 1.5ppm yellow powder can be spilled in the whole cylinder. If it is 20ppm, it can only be soaked for 15-30 minutes, and 50ppm can only be soaked for 10-20 minutes. It is usually necessary to stop feeding during treatment, and pay attention to changing water, heating appropriately, and adding a little salt. If the number of patients is too large, take medicine bath in batches. 1、 The time of medicine bath is usually not fixed for fish. It mainly depends on two points: one is whether the condition is serious, and the other is the concentration of medicine. Taking yellow powder as an example, 1.5ppm can be spilled in the whole cylinder, 20ppm needs to be soaked for 15-30 minutes, and 50ppm can only be soaked for 10-20 minutes. If it is a local injury, it can also be coated with 0.01-0.02% solution. 2、 Treatment 1. Stop feeding: fasting is required during the treatment of fish. Fasting here does not only refer to more than ten minutes of medicine bath, but do not feed from the onset to complete cure. Fish itself is more hungry, and can't die without feeding for a month. Moreover, during the illness, the fish lose appetite and can't eat much after feeding. The residual bait remains in the water, which will lead to further deterioration of the water quality and be unfavorable to its recovery.
2. Old three: for most diseases, the best treatment is the old three - change water, heat up and salt. Changing water can improve the water quality as soon as possible. Warming up is helpful to improve the resistance of fish, so that it can heal itself. Adding salt can reduce the possibility of bacteria invading fish with water.
3. Batch medicine bath: if you want to give fish medicine bath, don't soak them all at one time, but carry out it in batches. At most 2-3 pieces are treated together each time. After the medicine bath, take them out in time and put them back into the original cylinder. （GeiYuYaoYuYiCiDuoChangShiJian，ZenMeZhengQueDeGeiYuJinHangYaoYu）
