Red Eye Sliders Turtle

Question
I have two turtles and they both have this weird slice along their limbs its sort of red and the skin looks cracked i usually don't leave them in water unless their feeding. Can you help

Answer
How about a bit more detail huh? I have instructions that are at the top of the page when you ask your question. You provided no background info at all. We also have the option of a picture, and you should have included one of those.

If you have anything further, you can email me through my website, at wichitafallsreptilerescue.webs.com
