Skittish pretty much sums it up. I don't have any now, but have had several in the past. If I remember correctly, they also have a strange way of raising their abdomen when you're bothering them. I never perceived it as a threat pose, but it does kinda throw you off a bit.
My girl is skittish and really only willing to bite my face off when I'm taking her egg sac :-/ But my boys were VERY different! I slept with one eye open they were into such drastic threat possess they fell over on their backs. They bit the tongs and held on. I was pleased my finger wasn't involved.
These are one of my all time favorite species. The couple that I have now all seem to have very similar temperaments. VERY SKITTISH. Like run laps around the enclosure until they find they're hide when you turn the light on skittish. But they don't seem to be very aggressive. I have had a few warning slaps, but no fangs.
I own two females and neither of them is skittish. They will both of them "take your finger off" aggressive. My large one just sealed her burrow because she is ready to moult.For the last two weeks she has been even more aggressive than ever.My smaller one never uses her hide and will attack water droplets.But I love them both.Lol.
