My limited experience with them has been that they stress easily and are on par with some chameleon species as far as importance of having husbandry spot on and leaving them the heck alone. Not a beginner lizard. I've also encountered a couple that would ride around on my head and didn't seem to mind being pet, but in general, they can be pretty difficult. As previously mentioned, I think a big part of this is that you'll be very hard pressed to find one that is not wild caught.
