i think i want a hognose

[Bartman]

Im thinking i might want to buy a hognose, prefferably male since they get smaller. I didnt want a big snake since i already have to handle my bp and im not so big into snakes, but ive liked hogs for quite a while. Just a couple questions,

1) are they hard to care for?
2) what size enclosure would a full grown male hog need?
3) they will never need to eat rats right?
4) Is 18 inches the average for males?
5) Are their any really reliable caresheets for hogs?
6) how is their temperments?

thanks!
