I have two red ear slider turtles. One of them has a small amount of blood on the back of its neck. He seems to have stopped bleeding and the blood has dried. Also, the skin on the back of his neck has a white blotch like it has been scrapped and the green layer of skin has peeled off. I noticed the blood today, however a couple days ago I noticed that when he puts his head in his shell and sticks his head out that his skin on his neck rolls up. I have had them for over 5 years now and they have shared a tank the whole time so I do not think that this is due to them fighting. Does this injury seem likes it requires a veterinarian or is their something I can do to help the turtle.
Thank you
