Why is my turtle's shell white and peeling? Could it be shell rot?

Thanks for reaching out about Muddy and including photos. By the photos, the lesions do not appear serious. White lesions can appear from other traumas, of which algae can invade. Scrubbing the shell, and keeping water quality good, should work well. If lesions grow, seeking an appointment with a reptile veterinarian is recommended. Good luck.

The peeling scutes may be normal shedding. Do not attempt to remove them yourself. Maintain pristine water quality. You can use a soft bristled tooth brush and a diluted Betadine solution to gently scrub the shell or affected areas. Allow for a 1 hour dry dock (out of the water) after each cleaning. If the UVB bulb has been in use longer than 6 months, replace it. Make sure it is not blocked by fine mesh, glass or plexiglass. Provide a balanced diet including prey, fresh greens and vegetables and a commercial pelleted diet. Dust food and prey with both a multivitamin and a calcium supplement regularly.

Thanks for reaching out about Kelby and including photos. Can you gently scratch the white areas with your fingernail? Is so, probably mineral accumulations from the water and not a problem. If not, this could be keratin erosion from sub-standard water quality, infections, too cold of an environment. A veterinary visit would be recommended. Good luck.

Thanks for reaching out about Shelly and including a photo. The white on the shell could be hard water deposits that are not really harmful, but a new water source needs to be used. The white can also be exposed bone, which lies underneath the keratin of the shell. This could be due to dietary deficiencies, poor water quality that can erode shell and other problems. Without knowing the cause, there is no home remedy that can be recommended. Diet needs to include whole prey (fish), pellets and offer some vegetables (although many will not eat them). Good luck.

Thanks for reaching out about Squirt and including a photo. The two most common causes of this are mineral accumulations with hard water and exposed bone. Mineral accumulations you should be able to scratch off with a fingernail. Water source might need to be changed to filtered water or commercially available spring water. Exposed bone is usually due to poor water quality (high bacterial or algal loads) that erode the keratin layer. Water changes need to be made more often, but a veterinary visit is recommended as systemic antibiotics might be required. Good luck.

Thanks for reaching out about Jimmy and including a photo, although the photo does not depict white lesions. White lesions could be shed skin but that usually falls off. White lesions can also be infected tissue from bacterial or fungal infecitons. A veterinary visit can help with an assessment and diagnostic/treatment plan. Check and correct water quality as pristine conditions are required for healing and prevention of further problems. Review diet as vitamin A deficiencies can play a part in secondary infections. Good luck.

Turtles need more than a heat lamp for good health. Basic requirements include: clean water, a water heater, UVB light, basking platform, balanced diet and vitamins and minerals. Sunlight is good, however window panes and tank glass block most of the beneficial UVA/UVB rays that turtles need to synthesize Vitamin D3 and to properly utilize calcium. A good UVB bulb should be placed above the tank no more than 12-14 inches away from the basking area. It should not be blocked by glass, Plexiglass or fine mesh. The peeling and white spots may be due to poor water quality, poor diet, lack of UVB lighting or a combination of the three. Keep water clean via filtration and weekly partial water changes. Scoop out uneaten food daily. The filter should be rated for at least twice the volume of the tank since turtles can be very messy. You may be able to get Shelby to eat greens if you offer them about an hour or two after the heat lamp comes on in the morning. This will give her time to warm up. A cold reptile will not eat. Dice the greens and vegetables into manageable pieces. they should be dusted several times weekly with a calcium supplement and a multivitamin. Once she eats the greens, you can offer pellets and protein (feeder fish, nightcrawlers, crickets, raw beef heart, etc.). The spots can be gently scrubbed daily using a soft bristled brush and diluted Betadine or chlorhexidine (Hibiclens). Allow for a 1-2 hour dry dock (out of the water) after each cleaning.If it doesn't improve or if Shelby becomes lethargic or stops eating, then have her examined by a your veterinarian or a vet experienced in treating reptiles. Since most aquatic turtles are red eared sliders or yellow bellied sliders, I have included a link regarding care and keeping below. If you have a different species, post a new question with the species or request a consultation and we can discuss the case in greater detail. http://www.anapsid.org/reslider.html
