Yeah it's not worth argueing with them . I once had a battle with the Roseville, MN PetCo for months, because they had....now check this list here, in one large vivarium:
1 mature chinese water dragon (brown, thin, and wrinkly...sposed to be green and "plump"
4-5 leopard gecko's
4-5 Green day gecko's
2-3 bearded dragons
3-5 small lizards I didn't know the names of
20+ garter snakes
All in the same cage, on repti-bark. And EVERY lizard in there was partially shed with extremely dry pieces "stuck" to them. It doesn't take a genius to know that something is wrong here. The dragon was on his way out, he looked so pathetic and weak. I ended up taking him home and nursed him back to green and a nice weight, but one night he fell off his branch and must have broke something when he landed, or died on the branch and fell.
I'm fairly positive that this was due to his weakened state at PetCo, because he was sooooo ill there, that I'm sure it had lasting effects internally that I just couldn't see. When I bought him, they told me all he would ever eat was crickets! By 2 months here he was eating mealworms, earthworms, wax worms, crickets, grasshoppers, and mice. Had I kept him on only crickets, he would have died in days rather than months.
I told them that they needed to put the dry animals in dry cages, and the humid ones in humid cages. That snakes and lizards should NEVER be kept in the same cage, as lizards (particularly smaller ones like gecko's) are inherantly afraid of snakes. "Dinner!" After a few weeks of complaining, someone finally took the multitude of garters out, but still kept beardies and gecko's in the same viv, then a week later, there was over 20 green snakes in there! Again, lizards and snakes together!
Take the advice of the pro's here, like Don S, Kathy L, and just about 1/2 the people posting in here, rather than PetCo advice. One or two may have a person who knows about herps, but what I saw at my local store was a bunch of high school kids in the "work-program". I doubt they were snake experts.
Sounds like you've got it set up nicely now. I don't use lights, just the UTH on tanks and heat tape in the rack. Corns snakes don't need special lighting, but a nice normal day/night light cycle is good, and that can be acomplished with the sun
(not shining directly in the tank though, that'd heat it up in there fast!) Stick with the paper towels for a bit, then if you do switch, aspen is great, Carefresh is good also. CareFresh is usually in the small pet isle, it's recycled newspaper and comes in gray or bleached white. I used the gray for over a year and it is as easy as aspen, but probably 2 times the price. The one thing it has over aspen, is that it's paper, so should be digestable, but I still didn't feed on it.
