Nice species, I have three. They tend to be a little skittish, over the last couple years I've gotten one or two threat postures, neither with fangs extended. Will not hesitate to kick hair and are a lot faster than you would think looking at their usually bulbous abdomen. They tend to appreciate a little extra moisture, I usually will mildly water their tank with a gatorade bottle once every 2 weeks or so, but they tolerate arid conditions rather well. Enough substrate to burrow and they will, though it may take some months before they decide to. A water dish completes the deal. Mature males turn a beautiful blue-black coloration, I am trying to breed mine and am not having any luck.
I say go for it, they are cheap, pretty and unique looking with the abdominal shape and the swollen femurs (hopefully I got the leg segment right this time).
