Personally i would go with a red tail...
I got a couple rescues a few months back, they are great snakes, i love um to death im re-homing two of the three. I highly reccomend them, but as someone already stated, if you are looking for a python, I suggest Jungle Carpets, or well, Carpet Pythons in general... they are GREAT snakes. no doubt about it, they are one of the best snakes i have owned.
