My baby red-eared slider has white spots on its shell. What is it?

Updated On September 23rd, 2025

I have a baby red eared slider a friend bought from Chinatown then couldn’t keep. I believe it’s about 1-2 months old as it wasn’t even old enough to eat when I recieved it. I have him set up in a filtered tank with a dry rock area and some caves in the water that he likes to sit on. He’s developed a couple small white spots on his shell and I’m worried that it’s some kind of infection but I also don’t know if he’s maybe starting to shed his shell.

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
