Substrate: dry coco fiber / sand mix
Humidity: low; no water dish is necessary and occasional misting will suffice for moisture
Temperature: Hot (80s-90s Fahrenheit)
Decor: crevice-like hiding spots (stacked slate pieces are ideal)
Preferred hiding spot: in small crevices, sometimes digging out a shallow scrape underneath a rock (does not burrow)
Communal: generally not, though some people have reported success if plenty of hides and prey are available
Temperament: in my experience, Hadogenes
are shy, but defensive when disturbed
Venom: incredibly weak (LD50 reported at 1800 mg venom / kg body mass)
This genus is native to southern Africa, and as such like it dry and toasty. They are among the slowest-growing scorpions, and as such can easily go for long periods without food. Small crevices are ideal hiding places considering their flattened body shape.
I currently have one immature H. paucidens
who rarely ventures out of its hide. When I lift the hide it readily displays its pinchers, and if disturbed, frantically runs around the container. The last time I held this specimen it scurried very quickly and almost mistook the cuff of my jeans for a hiding spot. I don't know how skittish the adults are, but after that experience I do not recommend handling.Edit, March 2008: I have since acquired an adult pair, and the female displays the same temperament as my immature specimen while the male in incredibly calm by comparison. My guess is that either A) temperament varies from scorpion to scorpion, or B), the species is very skittish in nature and my male is simply an older specimen.
Edit, later in March: The male in question died, so apparently he was very old; the conclusion I draw is that this species if very skittish when disturbed and out of its hide.
