Rub iodine for egg turtles two to three times a day, return to the water after 15 minutes of rubbing, get more sunlight, and pay attention to water quality. Severely rotted egg turtles will lose their nails, and the rotten area of the affected area will expand and be slightly rancid. Dry egg turtles, wipe the affected area with iodophor to disinfect and then apply chlortetracycline ointment. Soak in water for half an hour every day to feed and bask in the sun.

At ordinary times, pay more attention to the water quality, change the water frequently, and let the egg turtle bask in the sun more. It can prevent the occurrence of rotten skin.
