This is my Juvenile Dragon, Evoo. His (I originally thought my baby was a girl but I now believe he is a boy) tail has always been dark at the end portion. It does get darker when he seems pissy. It sheds differently than the base of his tail, but does shed. It has the same texture. As he’s grown, it has grown proportionally so it still is about the same portion of his tail that is significantly darker. I believe it’s just normal coloration, but as a first time mom I am worried about everything and want to make sure I’m doing right by him. I’ve included a picture for reference. Thank you!
