do you mean the Rhino Ratsnake (Rhynchophis boulengeri)?
those are sooooo cooool!
I got to hold one recently and it's prehensile tail was amazing! It grabbed my arm like a living vine out of a monster movie!
Information is spotty....I have been gathering info in the hope of getting one at some point in the next couple years.
Unfortunately the folks I know of who keep them do so in breeding setups, so I've had a hard time finding information on keeping them as display animals. They would be awesome in a naturalistic setup I think!
