I have a 4 year old V. ornatus at the moment. I acquired him as a CBB hatchling at 3 weeks of age. Having successfully raised trusting Niles and waters in the past, I knew the amount of patience required and the requirement of protocols when working with these animals.
I have no problem going in his enclosure, though I normally just open one of the doors and he'll come rest his head on my arm and look around. These guys are super rewarding to keep but are for the very serious enthusiast only.
