My Russian tortoise has a white spot on its shell. Should I worry?

Check environmental parameters first. Make sure the relative humidity level is correct. For Russians, it can range between 40% and 60%. Provide adequate UVB lighting. If the bulb is more than 6 months old, replace it. Provide a balanced diet including vitamin and mineral supplementation to promote shell health. Survey the enclosure and remove any sharp rocks or furniture. These can cause small scratches which can lead to infection. You can gently clean the shell using a diluted Betadine or chlorhexidine (Hibiclens) solution once or twice daily. If there is no improvement in the shell condition after 5-7 days, consider an exam with your veterinarian or a vet experienced in treating reptiles.

Thanks for reaching out about Toby and including photos. If is difficult to see the lesions in the photos but can you scratch them with a fingernail? Mineral deposits by hard waters can leave residues. Erosions of the shell's keratin can expose the underlying bone, possibly due to trauma, infection or other. If lesions progress, a veterinary visit is recommended to assess. Good luck.

Looks can be deceiving, but the shell looks fine in the picture provided. "Heathy" is more than just a clean shell though. He should be eating and defecating normally, basking regularly and swimming. There should be no redness or pitting on the shell. Provide clean water at proper temp, a basking spot also at proper temp, UVB lighting and an appropriate diet. You can review the article at the link below to confirm correct husbandry. http://www.anapsid.org/reslider.html

You can use a soft bristled toothbrush to gently scrub the area. Maintain clean water and provide a health, balanced diet along with adequate UVB lighting and vitamin supplementation. all these will promote shell and overall health. Monitor for spread, bleeding, lethargy, loss of appetite, softness or pitting. These are symptoms that should be addressed by your veterinarian or a vet experienced in treating reptiles. If you can provide the species of turtle and an image or two in a new post, we may be able to provide more specific advice.

It could be some minor shell rot. Use a soft bristled toothbrush and some diluted betadine or chlorhexidine (Hibiclens) to scrub the affected area once or twice daily. Allow for a 1 hour dry dock (out of the water) after each cleaning. Maintain pristine water quality via filtration and regular partial water changes. If the spots do not resolve or if they spread, have Squirtle physically examined by your veterinarian or a vet experienced in treating reptiles. A UVB light source, calcium powder and multivitamin will promote shell health. You can also float a piece of cuttlebone in the tank for him to munch on as needed. It will provide additional calcium. Find the cuttlebone in the Bird section of the local Petco. The link below will provide additional information regarding the care of sliders. http://www.anapsid.org/reslider.html

This is a tough question to answer without maybe some photos to reference what you are talking about? The spots can be from a bacteria or fungal infection, calcium in her diet, wounds from rubbing etc. maybe try to repost with some pictures and I can try to give more specific advice?

Keep the water as clean as possible. You may need to empty and scrub the tank then perform partial water changes frequently. If you can handle it safely, gently scrub the spot with a dilute betadine solution. Allow him to dry thoroughly afterwards. Do this daily for two weeks. If the water changes and scrubbing don't work, dissolve 2 tablespoons of plain aquarium salt (NOT table salt). Per gallon of water in a large basin and dip him in it. Allow him to dry before returning to his main tank. Do this daily for two weeks. If the spot still doesn't clear up or if it spreads, he will need to be physically examined by your veterinarian or an experienced herp vet.
