Hi, I have been doing alot of research and first was debating if i should get a pet snake, i love snakes by the way and after comparing a cornsnake and a ball python I found a ball python would probably be the best for me but there are a few things i am worried about. First do ball pythons really bite alot and if so how bad does it hurt like on a scale of 1 to 10, 1 being a pinch and 10 your arm being cut off, And is a 20 gallon long ok for the first year or so? Thanks for the info!
