Why does my red-eared slider have white patches on its shell?

Updated On September 23rd, 2025

Pet's info: Reptile | Turtle | Female

My red eared slider is 1 year and few months old. She got white patches around January 2019. She still has them. I made sure she ate all protein and vitamins regularly. I kept the tank clean upto the standards. I also treated her shell with drops of betadine for almost 1 and a half month. Yet it’s still there. The turtle seems to be unaffected by this. Is it normal? Or should I do something about this? Give me a home remedy as there are no vets near the place i live.

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.
