About 30 days ago, I was cleaning the tank. I placed Shelldon in a grey plastic tub that I usually place her in when I clean the tank. The week before, she had gotten out so I filled it with less water than usual. However, she still got out and scraped her head. The skin was peeled back but still attached. I put her back in the tank, and after a day, the skin was fused back, though it left a mark. It has been 30 days. THough the skin is still fused, with no signs of loosening, I can still see the border where the skin was originally peeled, and it is slightly lighter in color, leaving a visible "mark". I've talked to a vet, and he said that though he could not really know for sure without looking at it, it didn't seem like anything to worry about. I have talked with several pet store and vet consultants and they all say not to worry. I'm still worried though even though there is no redness, swelling or any change in behavior. Will this "mark" eventually go away?
