Back to venemous snakes, have you thought about Bothrops alternatus or the Urutu? I have only had one and it was one of the easier hots I have had. The colors and pattern are absolutely awesome. It was a very cal snake that did not show signs of aggression. It rode a hook well and it ate well. It was one of the easiest hots I have ever kept. They are something different from the North American hots. I am not sure if Cro-Fab would work with them but I don't see why it would'nt.
