Well, temperment isn't based on mutation. Do you mean is a bp a good first snake? Most will say yes, but it depends on the person. Try taking care of your bf's snake and see.
The thing is I was never a snake person but since my bf got one i find myself on here all the time and googling things to find out more about his bp so i feel more comfortable around him. I just get so nervous when Im holding the bp that hes gonna strike at me.
