i'd agree on the corn snake being a good "starter" snake. they are very forgiving for minor husbandry errors...unlike a lot of various species. now a corn snake is a sub-species of rat snake. the regular corn is also whats known as a "red rat snake." Corns are one of the smallest species of rat snakes, but there are others close in size. for example you may be interested in a texas bairds ratsnake. they grow to the same length, 4-5 feet, and i love mine. its just up to you, i would reccomend a 29 gallon though - strictly because corns and rat snakes love to climb, and you can give them more climbing room in a 29. but a 55 would be a lot better even!
