Hey all. I would like to get a snake, one that must be arboreal. I am looking for something that is more of a display snake, something that stands out from the ball pythons and corn snakes? Maybe something blue? I was interested in amazon tree boas and pythons, but they are $200 at least, and I am looking for something a little cheaper, i am on a budget. I was thinking maybe an Asian vine snake, or something of the like? Like I said, I think blue snakes are gorgeous (blue insularis are amazing), so something preferably blue. What would you guys recommend? I hope I am not being too picky.
Thanks!
