All animals have the chance to be "bitey". Too many factors to really take in like like wild caught, personality, how it was raised etc. If being very general, I would say balls and bci are pretty mellow. Now as for an example, my ball bit anyone who picked her up as a baby except me. No one liked to handle her cause of the fact she would always try to bite but like I said, I picked her up and she has never made any attempt to bite me or anything and I've had her just over a year now. Bottom line every animal is going to be different. I've even heard of people with anacondas that were puppy dog tame and they are known for being rather ill tempered.
