About the white thing growing around the neck of a Brazilian turtle.

God, don't dig with your hands ~! If it's rotten skin, the turtle is in pain. . . It may be infected.

Two turtles in my family have suffered from this disease. Go to the bookstore to read books and gain practical experience. The medicine used by the little turtle is generally for external use, mainly several antibiotics. Disinfect with disinfectant before external use. I recommend potassium permanganate solution, but remember to dilute it again. Gently rubbing the solution with a cotton swab and applying roxithromycin eye ointment can help to use oxytetracycline, and oxytetracycline powder can be mixed into food, not too much. White skin will naturally fall off in a week or so.

Also, be sure to remember to let turtles do more exercise and get more sunshine. If you are seriously ill, you should go to a pet hospital. I hope your turtle can grow up well, too! !
