The main reason for the white spot disease of Siraitia grosvenorii is that the water temperature is too low or the temperature difference is too large. For example, if the power is suddenly cut off and the heating rod stops working, the bacteria in the fish tank will have an opportunity to take advantage of it. In addition, the temperature difference between morning and evening in spring and autumn is large, or the temperature between new water and old water changes greatly when changing water, so it will suffer from white spot disease.

If the disease of Siraitia grosvenorii is not serious, the breeder only needs to transfer them to a separate fish tank, raise the water temperature to about 32 ℃, and finally give the sick fish a medicated bath with 2-5ppm methyl blue. Take a medicated bath once a day for 30 minutes, and it will get better in about 3-5 days.

If the disease of Luohan fish is serious, the breeder should first replace all the water in the fish tank, and then disinfect the fish tank with potassium permanganate solution. After disinfection, add the exposed tap water and oxygenate it for 1-2 hours to ensure sufficient oxygen in the water. Before Siraitia grosvenorii enters the new tank, smear it on the affected part with methyl blue first, and then take a medicated bath with white spot net. Repeat smearing and medicated bath every day, and you can recover in about one week.

During treatment, breeders need to keep the surrounding environment stable, especially the water temperature and quality, and do not change too much. And stop feeding. After they recover, try to feed them.
