My adult rough green snake, Roxy, has black/blue splotch on her body. I'm really hoping its not septicemia. If it is, I don't think the treatment will be cheap. It might cost more than what I spent to get her. Its definitely not a burn mark because I use a UVB light and doesn't get too hot. There's no swelling and that's the only spot affected. She's not red at all and I have no idea what it is. If at all possible, any helpful information is much appreciated.
