I'm watching my friend's snakes for a week or so and we noticed this before on his GTP but just figured it may just be his color changing. The GTP is a Sorong male and he's tealing up on his sides and his mouth. We noticed these symmetrical black spots between the eyes and the nostrils. The spots have gotten a little bigger since when we first noticed them but I wanted an opinion. Took some photos the other night for a visual on what it is. To me it doesn't seem like scale rot because that usually seems to start on the belly of the snake, and that these two spots are exactly symmetrically horizontal from each other. Your thoughts? Is this just the start of him turning teal? Or maybe something else of concern?
