Looking for an iguanid...

[lizardminion]

I'm searching for an iguanid(or rather, anything iguana in name only, like Corytophanes cristatus) that can be maintained in a home terrarium, and is suitable for captive care. I am interested in mainly smaller species; nothing that gets too big, as the green iguana does. (hence my first statement) I don't care for striking colors; anything will do, really. Also, it must be possible to breed in captivity as I am looking for captive bred stock, and may consider breeding them in the future as well. I would greatly appreciate if I can keep a pair(or more) in the same enclosure. I would prefer a species that is able to be handled and tamed, not one who will be defensive, too fast, and quick to escape. I would prefer a species who is herbivorous or omnivorous, however, I don't mind a carnivorous animal should it be all that's available.
Lastly, it must be available in the U.S. and must be at an affordable price.

Would you all say chuckwallas or desert iguanas match my description?

I had a desert iguana.. they're super fast and don't handle very well at all. I also had issues getting mine to eat. He was a very nervous species and would only eat if no one else was in the room making any noise, and the cage was covered. Otherwise, he'd starve himself. I'm not sure if that's true for all desert igs, but it definitely was for mine. They also really need a larger enclosure than you'd think they would... but it's still nothing compared to a green iguana! I think it's an accomplishment when someone is able to get one to eat out of their hand or are able to even touch the head without it freaking out. But I'm sure with work one may be able to calm down... but nothing like bearded dragon calm at ALL. More like calming down a green anole or something, haha

Could have been wild caught. I've read statements contrary to your post, as I've read that they quickly acclimate to captivity fairly easy, although they are an energetic species as they are fast and wiggly.
Aside from their speed, the only other con I've read about is their need to for blistering heat.

Also, I forgot to mention I plan on building an enclosure. The material I'm using though will vary depending on species. I'll use wood for dry species, but something else should it be a tropical species.
