Most of the bad reputation is from the imports, and that is not entirely untrue. Green tree pythons had the same reputation 10 - 15 years ago. Especially the Biaks. But as more and more are captive bred, the perception of them has softened considerably. If you get one, I would highly recommend a C.B. baby. This little one is completely tame so far. She still has to grow up, so we'll see how she turns out.
