1. Parasitic infection: Goldfish suffering from gill rot disease is mainly caused by myxosporidia or Chinese flea parasites. The main reason is that the water quality is too poor or the live bait is not disinfected and sterilized. Generally, the initial symptoms are white gills, dull expression, reduced food intake, and lack of swimming. In the middle and later stages, the gills will be red or bloodshot.
2. Bacterial or fungal infection: Bacterial infection is mainly caused by unclean water quality or low frequency of water change, resulting in water mold in the water, which leads to goldfish infection. The initial symptoms of bacterial infection are also white gills, but in the middle and late stages, the two gills will appear similar to cotton wool. The mortality rate of bacterial infection is relatively high, and once it is found, it needs immediate treatment.
the white gills of goldfish? 1. If it is due to parasitic infection, you can isolate the white gills first, then wipe the gills with salt water and then take a medicated bath for about 15 minutes. In the middle and later stages, the goldfish can be bathed with 0.06 G of trichlorfon per 1 kg of water, once a day, 15 minutes each time, and can recover after a week.
2. If it is due to bacterial or fungal infection, it also needs separate treatment, and the oxygen supply during treatment should be adequate. The goldfish can then be medicated with a 2 ppm malachite green solution for 30 minutes once a day. You can also use a 15-watt ultraviolet lamp to irradiate the fish tank, which can effectively kill the water mold in the fish tank.
