It's possible, my BP Boris is about 18 months now with a very dark brown in his color pattern and he's aggressive as hell! I have no idea what's wrong. He's just extremely cranky most of the time. He's bitten me twice and hisses like crazy about every other time I try to take him out. I'm not sure what to do about it. I thought maybe he's blind and thus very frightened of everything, but maybe it's just the way he is...idk
I thought about putting another snake in with him but that could end in one of them being hurt so I don't know what to do other than to be very patient and kind with Boris.
