Hello!
I have an adult quad. He's an apparently healthy little bugger and, while he has not been sexed by a herpetologist or vet he does have all of the characteristics of a male.
He's a demon. He likes to snort and hiss and bite. He is, however, a good looking lizard.
I live in norteastern CT. If you are in the area maybe I could loan him to you if you're interested. I could get you some photos but it might take awhile since I don't own a digital camera and would have to borrow one.

Let me know,
Jay Hyland
