It's terrible that they keep these animals and don't even know how to take care of them... Oh well it's just how SOME of pet stores are.Beautiful corn snake by the way. Well I would advise having a warm and a cool side. The cool side being 76-80 and the warm side being 84-87. DO NOT USE A HEAT MAT WITHOUT THE THERMOMETER. If you don't want to use a heat mat( like me) have a day bulb on one side of the tank and a night bulb on the other (Ex. For a 20 gallon use a 50 watt night and a 75 watt day). Corn snakes or at least all the ones I have seen love to burrow so make sure you have something they can burrow in like aspen or reptibark(what I use)NO SAND. Plenty of hides since he just a baby and scared of everything. Try to have a humidity box for when he sheds.This is a picture of what I have my 30 inch corn snake in. Hope this helps.
