>>333730herecorn snakes will do fine in a ten gallon as well. most corn snakes and king snakes will get 3-5 feet depending on the species. Theyre much prettier to look at than ball pythons IMHO,but if he wants a big snake for shock value like a ball python, they dont do as well. find a pet store that has a good selection, there are literally as many different kinds of snakes as there are kinds of fish in the sea.
Snakes are my favorite animals, i've owned quite a few.
protip: ask to handle whatever snake youre interested in before buying it. Ones who poop on you or try to bite, usually continue this behavior for a very long time, sometimes forever. Not necessarily all the time, but when you take them out of the cage definitely. So do yourself a favor and try to avoid the poopers. In my experience, male snakes tend to poop alot less than the females. although im talking kingsnakes, ive never had a python poop on me.
I suggested variables because those tend to be very calm, easy to maintain first snakes. If your boyfriend does not like getting pooped on, i cannot stress enough to pick out a snake that doesnt do it the first time you pick it up. I used to have an orange pueblan kingsnake (female) who shit on me every time i picked her up. She would also shit in such a way that it would run down her tail, and then flick it at me. She got it on my face a few times. Don't get an orange pueblan.
