I currently am the owner of my baby girl, Queen Elizabeth... I am sure someone has heard of her I am her BIGGEST fan!

I have recently been interested in purchasing a second addition to my love collection... (which is as of right now only 1)... and I have been looking at ball python morphs... I do not want another normal ball (which is what Queen Elizabeth is) I want something "exotic"... but they all cost (starting) 150 (normally 300 ish) for anything that I would want... (I am not into 5k for a hypo lavender this and that) but recently I have been looking at corn snakes... I have a friend that has them... and she has five of them... all sizes and ages... and they are all nice enough.. some more than others...
my real question is this:

What is the tank set up like for a corn snake?
My ball python requires SO MUCH MAINTENANCE... like... temperature gradient and heating pad and humidity and all that jazz... are corn snakes just... a hide... water bowl... and bedding and then basic snake room temps? I would have a lamp above the tank... for ambient heat... would the corn snake need a heating pad? Multiple hides and security like a ball python? Their food prey would always be small right? Like even at full growth... still a medium or large rat, right?
please correct and inform me!
Peace
