Hi i have a red eared slider.I was given this by my sons ex.The turtle is stunted,it was keep in a small tank.No heat lamp,it cant swim.The water was kept clean as far as i know.I have had it about two months.The shell is pitted,it has had one moult since i had it.The shell still has places where it is pitted,and some nice smooth shell which looks nice,no soft parts.I am treating the shell with betadine antiseptic ointment.Any other ideas.It has improved and is happy and full of life
