Ball Python or Cornsnake?

[shelliebear]

Cornsnake is probably cheaper, both morph and food wise. As adults a corn probably wouldn't eat anything bigger than a small rat, and as babies they eat pinky mice which are fairly cheap.
They don't require their temps or humidity be as high as BP's, and most will use Aspen shavings as a place to hide instead of an actual hide.
Cornsnakes could be put in a 10 gallon tank while younger, probably up to about 1.5 years (depending on growth), which would equal a pretty small tub. Not sure how many quarts--maybe 5 ish?
Something to think about is the age of snake you get. With corn snakes, (I own one! ) as babies, they are wriggly little shoelaces. They won't sit still just like a ball python will most of the time. They're barely big enough as babies to wrap around anything so they can't hang from your neck while you do homework, if that's what you're looking for.
Both are beautiful kinds of snakes. Corn snake morphs are a lot cheaper, though it's sad that they are for breeders and future breeders.
As for temperament, both types of snake can be nippy as babies. My corn snake has never struck at me, but then again, neither have my BP's. It depends which snake you get. See if you can monitor one you're interested in for a few days. Hold it in your hands, see if it's aggressive when you're getting it out of the tank.
I'd say probably go corn snake. Especially since with a BP you have to be prepared to either hook a humidifier up in the snake room to keep the humidity up (you live in Canada, I'm in Washington state just beneath ya'll and our humidity is awful), or spray the tank with a bottle until you have arthritis, LOL.
Read some of the care sheets on this site if you haven't already. After that, it's up to you. Find a breeder if you can, and I bet you my left arm they'd let you hold the snake and look at it before you buy it.
Ask for one that doesn't bite a lot.

Good luck! I want pics when you decide
