Bulls for the most part have a good attitude if you handel them consistently from when there young. I own 5 bull snakes that have all calmed down. But there are always a few exceptions to the rule. They get a bad rap because all of there hissing and rattling they can do (which ussually calms down as they get older). But I just think this is personaality.
Thanks for all the nice replys. I will post pics if I can get them to breed this year.
