Just google argentine tegus and see if that is what you are going to want. Tegus eat a wide variety of food and a varied diet should be provided. They will eat ground turkey, mice, rats, some brands of dog food, some will eat veggies and fruit ,just to name a few. The enclosure could be as complex or simple as you wish. The minimum size will really depend on the type you get. For example Reds are the largest you can get(about 4-4.5 feet) with Black and Whites being second(about 3.5-4 feet) and Blues coming in as the smallest. All of these should go thru a hibernation which can start between september-november and end somewhere between march-may. Tegus are fun to work with but not for everyone. Do the research and good luck with it. I am sure you find them to be great lizards. And just a side note: Uromastyx do go through a burmation period.
