First of all, congrats on deciding to get a corn snake! But watch out, you'll probably catch the snake bug end up with five more by next year :grin01:
Second, I'd suggest doing a ton of research. There are some great care guides online and lots of good stuff in the FAQs on this site (definetly pay a visit to the Husbandry/Basic Care FAQ). I would also suggest buying Kathy Love's corn snake book.
Third, a baby corn is not gonna need a 30gal tank (I'm assuming you're getting a hatchling as that's what most people do. If not, 30gal is perfect for an adult). If you are getting a hatchling, a 10gal would work great. Just make sure you get one with a locking lid as snakes are master escape artists.
Fourth, as far as stuff to put in the cage, anything goes really. Once you have the basics in there (two hides, waterbowl, UTH, aspen bedding is great

) you can add as many decoration things as you want. I just got some of the climbling logs at Petco and Zeebo seems to enjoy those.
Last, I would suggest buying your snake from a breeder. The cost may be a little more expensive, but by doing this you'll ensure a good feeder
and you'll know the hets and sex of the snake-not to mention the much wider variety in colors. If you do get one from the pet store, however, be sure to ask the store employees when the snake was last fed, if it eats f/t or live, how often they feed, and if they know what sex it is. That's about all I can think of. Enjoy your new corn snake
