well this started just recently, i went to go pick my baby bp up and it hissed a little. it hasnt bit me or tried to since i got it. it has always been jumpy, not in a snappy way, only jumps if you surprise it. he also tries to climb up the tank sides. maybe he is just hungry? i feed him every week 1 hopper. the temperature in there stays from 80-90s. thanks.
