Fungal Infections Fungal infections are fairly common among red-eared sliders, especially younger ones. If you notice what looks like a light layer of cotton on your slider’s shell or eyes or in its mouth, this is most likely some form of fungal infection. Although their appearance can be alarming, most infections in their early stages are fully treatable at home. If a fungal infection remains untreated, however, it can spread across the entire body and cause serious harm to your turtle. To treat a mild fungal infection, immerse your red-eared slider in a warm saltwater bath for about half an hour each day, using a soft sponge to gently scrub the infected regions. You can also treat patches of fungus with topical applications of a mild antiseptic, such as povidone-iodine. As long as the problem isn’t severe, you should notice signs of recovery within a day or two, and a full recovery in about 10–14 days. If your turtle has a persistent fungal infection that home treatment isn’t curing, take it to the vet for treatment. Several medications are available that can address a fungal infection if it hasn’t spread too far. http://quamut.com/quamut/redeared_sliders/page/redeared_slider_healthcare.html
