You are right there is virtually no information out there on this particular species. It is a real experiment in keeping this species.
I have had "Pugsley" going since August and he is fat and thriving.
Only this last few weeks has he started to spend more time relaxing than he has clawing against the glass. Its great to see him taming down more. I am not positive, but I get the impression that most of these Arabian Toad head Agamas are wild caught imports and that is why they take so long to mellow down.
I am dying to get Pugsley a mate, but no one wants to sell single females.
How do you have yours set up?
Here is a recent photo of my toadhead agama "Pugsley":
