She looks pretty young to me...but her tail looks healthy! You know we can't see most of her in that photo?

Hard to tell on the sex but if she's that long, I would say maybe she's around 6 months. My male when I received him was 3-4 months old, and he was 19-21 inches. Yours looks a little bigger than that.
