This year will be the first time I ever get some corn snakes. I am not new to snakes I have had california kingsnakes before in the past and I plan to get some cali kings later on in june or august. How big of a tank do need for a new hatchling 2003? i was wanting a male and female from 2 different egg clucthes. are corn snakes cannabalistic like kingsnakes or can you keep them together? I heard some rat snakes are cannabalistic.
