Hello and welcome. Each snake can be different but I've found that babies are more likely to strike out. They mellow as they get older. My little guy nailed me when I wasn't paying attention and I didn't even feel it. I had two pin pricks of blood. It rated a -2.
I like corns too but to me I like that balls are mellower. A 20 gal long is great. Just make sure that you get the husbandry right and you'll do fine. Good luck with whatever you do and ask any questions you have![]()
