I would have to second jrbl comment on the Prehensile-Tailed Skinks as a choice.. there not for everyone.. First off the getting harder and harder to find, and captive breeding efforts need to be made..So if you want a pet just for that reason.. I would stick to a Blue Tounged there pretty bullet proof and they have great pesonality.. for a nice display lizard then go with a tribs....and Finally Pink tounges are great, but i have hear reports that some can be picky eaters.. unless you have friends with snails..
But in the end the choice will be yours, Prehensile-Tailed Skinks are great i have six of them and I am always looking for more... I love when their little fishhook like claws dig into my skin, but hey they have great personality...except went gravid...
