I just got a Pterinochilus murinus and it was psychotic for about three days, and now it's calm as can be. Not even my G. rosea is that calm. I don't risk holding it, though. My dad thinks it's trying to lull me into a false sense of security. Ha ha. I'm a little confused with this guy though, cuz he just sits in the top corner of the cage all day. I thought they were supposed to be terrestrial. Any comments?
