Even if you decide you dont want a hog and you decide to get a common columbian boa they dont get that big either. Males are usually from 5-7 feet. And they honestly dont grow that fast at all, I've had my columbian boa for over a year and hes not even 4 feet yet. They are very docile and he has never struck or hiss at me. People mistake boas thinking they all get large but they do not unless they are a female or a BCC. The only time i can tell my snake ks growing is when someone who hasnt seen him for a few months and they tell me he got so much bigger. Otherwise you cant tell.
