1. Bleeding: Hemorrhagic disease is a common ornamental fish disease, which is caused by many reasons, which may be caused by water quality deterioration or bacterial infection. If you want to treat this disease, you should pay attention to changing water and heating up, and add yellow powder to the water, so as to have the effect of sterilization and anti-inflammation.

2. Gill rot: There are two kinds of gill rot, one is parasitic gill rot and the other is bacterial gill rot. Parasitic gill rot is rarely encountered in family fish farming, but bacterial gill rot is encountered. At this time, yellow powder needs to be used, and the dosage should be determined according to the condition. If it is used too much, it will cause drug damage.

3. Enteritis: Enteritis is usually caused by irregular feeding. Poor water quality may also cause fish to get sick. If you want to treat it, you need to take a yellow powder bath. During the treatment, it is best to stop feeding, so as not to get worse. After the fish recovers, it can continue to be fed, and at the same time, it should be quantified regularly.

There are two ways to use yellow powder. The first way is to take a separate medicated bath, take a proper amount of old water, add yellow powder, stir evenly, and then put the sick fish into it for dipping and washing treatment. The second is the whole tank of medicine. Generally, there are more sick fish, so this method will be used, and the water should be changed the next day. If there is no recovery, continue to add medicine.
