well males get smaller then females .females get bigger cuz they lay the eggs. i would go wit a female bp. and bps dont get very big only 3-5 ft. ive seen a huge bp but they are very thick and not too long. and if im not mistaken snakes dont have emotions just some snakes dont like humans soo then you will have a very snappy mean snake. and snakes grow on how much you feed them they eat mice then rats on how big they are . soo i would feed a bp once a week
