I have previously housed both turtles in the same tank. Yesterday I noticed a white spot on one of them and immediately removed it from the tank into another container. I gave it some betadine, left it dry for 15 min and then put some 1% clotrimazole anti fungus cream over the entire shell. I put it back into the container with about 2cm of water. Today I repeated it but dry docked the terrapin for 10 hours.

I checked the other terrapin and am unsure if it has shell rot too. Attached are pictures of them. Also, can I check if I’m doing the right thing for them?
Their tank initially had a filter and basking area and UVB+UVA light. I’ve included a picture of the tank set up as well. Thank you everyone!
