The treatment for white point disease in lionhead goldfish is simple. First, isolate the sick fish and then use red potion or iodine to apply it all over the body. After that, put it in the water with a little salt and the water temperature is at about 30℃ and apply the medicine once a day. After 3-5 days, the condition will improve significantly. When caring for it in general, you should also pay attention to the prevention of white spot disease. You should change the water for the fish in time to ensure the water quality is clean. You only need to change a quarter or a third of the water at a time so as not to create a big change in the water quality and make the fish uncomfortable. In the fall and winter when the temperature changes, pay attention to the appropriate increase in water temperature, to eliminate the creation of a suitable environment for the growth of parasites.
