I need to get a backdrop at some point for it, but that's pretty much my set up [minus the bark, which was replaced with another exo-terra cave].

As to whether they're captive bred I doubt it, don't think they're particularly widely bred, but I don't know for certain. They are highly skittish and have a bit of a tendency to freak out, nothing major but want to lessen that as best I can. They are a species I'd love to get a successful breeding for, it is a pleasure to keep them.
Agamas sp. in general are a skittish species. There are a few exceptions, like some painted agamas, but for the most part very flighty. The codylids that I have owned have always been very scared of movement and run at almost everything. I'm training one of my male smaug mossambicus by handling him more. It still freaks him out though and I've got bitten many times.
