I'm getting ready to set up a tank for a corn snake and I have a question about dimensions. I've got a ~28 gallon fish tank that a relative is letting me have, but it was designed for viewing creatures more suited to a vertical environment. its base is 30x12inches, will this be deep enough for a full grown corn snake to live comfortably in? It is 17 inches tall, but I gather that corn snakes are not as big on climbing as ball pythons and green snakes.
