Thx for the relpy dude-!I've not kept them, but have heard that they tend to prefer slightly moist substrate, so I would keep about half the sub moist by overfilling the water dish weekly to allow them a range to choose from. Also that they'll burrow if given deep enough substrate and will tend to stay in the burrow most of the time. Supposedly they will stand their ground if challenged - not particularly prone to biting or bolting, but will throw a threat pose willingly. Heard they're good eaters but slow growers. Hope that helps.
It seems the common name "cursor" mentioned in the link you attached matches with the same species I was looking for(likely). Anyways, thanks-!Haven't kept these myself but this might be a good starting point :
Cyrtopholis cursor?
