My patience has run out. That is a Taiwan beauty, like it or not. If you still don't believe me, tough, you can wait years for him to become blue but it will never happen. I am sorry the seller mis-identified the snake and likely charged you what a blue beauty is worth (more than a Taiwan). Michelle(or Crissy?), I am aware of the ontogenetic shift blue beauties undergo.... but the tongue will always be red.

Sorry If I came off as being rude.
