Out of the 7 BPs we have, only one is aggressive, and she's just a baby. I got her 2 weeks ago at the reptile expo in VA. She actually bit my 11 year old son (just a warning strike, she didn't hold on or anything), and all he said was, "ouch." She didn't even leave a mark. Generally snakes calm down as they get older, so even if you get a nippy baby, that doesn't necessarily mean it will stay that way.
