Also temperments can really differ from individual to individual. Best bet, get a captive bred animal that's fairly young and you should end up with a really nice tempered snake. Having said that, my little Petra (my female T.s.concinnus) always bites me every time I go into her tank, and I've had her since she was a hatchling. Go figure! Think she's just an over zealous feeder and not really mean.
