I've got 2 california king snakes and 1 snow corn. Corns are probably the best all around snake to keep and don't require any special lights other than a heat lamp at one end of your tank to keep warm and a cooler end for it to escape the heat if needed. Make sure the tank or enclosure has a escape proof lid. They are experts at getting out of the smallest of openings. The substrate I use is aspen shavings. Stay away from cedar or pine as these have oils in the chips which will cause respiratory problems. Coconut bark is ok too as is news paper. For feeding, have a separate place to feed them. It can be a rubbermaid bin another tank or even a box, but watch them so they don't climb out. When you feed them out of it's home, they tend to not get as excited when it comes to feeding time and it also keeps them from ingesting any wood chips too. There is a reptile show coming up in Mississsauga on Courtney park road on June 13 th ( I think it's that date) and you can choose from a wide variety of sub species of corns. Okeetee's are thge most colourful as are naturals. Any corns that have red eyes such as snows, albino's lavendars are light sensitive and will hide out of site all day until it's dark as they are mostly nocturnal. Check out this site for more info

Get the largest tank you can fit it. A 30 gallon will do fine, but when they get full grown wihch can be up to 5 feet, that tank will get small. The reptile show also has plenty of used tanks and lids you can get for almost nothing. Good luck.
