I am a complete noob when it comes to Turtle keeping but heres my setup. Small Painted turtle in a 20 gallon High tank with a turtle dock and a UV 5 bulb. I have recently noticed that the turtles shell is looking like it is peeling around the edge. Almost like a full layer is coming off. I do weekly water changes and run a filstar XP1 filter on the tank. I keep the tank water around 70 degrees. I was wondering if this peeling is kind of like molting or is it something to worry about. I feed repto-min and occasionally some jumbo krill if i thaw too much for the fish. I just pulled one of the pieces off it feels like a layer of thick dead hard skin. seems quite brittle. If this is a problem please let me know what I am doing wrong. I strive to provide the best possible care to all my pets.
