I have kept Desert iguanas, Dipsosaurus dorsalis, in the past and I really liked keeping them. Mine were wild caught and Im not aware of anyone working with them as far as captive breeding goes. Occasionally they show up in the Classifieds section of this website.
There captive husbandry is similar to that of the Chuckwalla. They need a large desert terrarium, as they grow rather large (up to 16 inches ). A hot spot of about 105-110 degrees F and an ambient temperature of about 85 degrees F. Lots of rocks and cover as they are rather skiddish around people. They do tame down and some can be quite handleable. One of mine would eat when I was holding it! They eat leafy greens such as Collard in captivity. In the wild they are almost completely dependant upon the leaves of the creosote bush as food. They love dandelion and mustard greens, and especially the flowers.
They will also eat and relish crickets and roaches.
Hope this helps! Any questions just ask or e-mail.
