My turtle, Lucy, has been with me for about nine years and so far she has had no health problems at all. However now she has developed some white fuzz on her skin, mainly on her neck. It is somewhat visible in the second photo. In the first photo, you can see the fuzz at the top of her rear paw. You can also see the fuzz floating around in the water in both photos. Her shell looks perfectly normal.
I tried some fish fungus treatment, API Liquid Fungus Cure, twice and it has had no effect. What do I do now?
