Thanks for your timely response!

I haven't experienced any hostility first hand with iguanas, but I do recognize their strength and danger. They are, however, still a very impressive collection of animals.

I am leaning towards a B&W Tegu as well. Though I would get one of Varnyard's Extreme Giants, or their All American hybrid. The Giants get to at least 5', and the AA's are pretty interesting, being 1/2 Giant, 1/4 Red, and 1/4 blue.

Do you or have you had a tegu before?
