Make the enclosure fit the snake, not try to make the snake fit the enclosure. Meaning simply, some snakes and reptiles require a lot of room. Balls like burrows and hides, my corn snake likes to bask out in the open.

Does my corn snake go in a rack? No, he gets a large enclosure, and he cruises around it, perches, burrows, basks on his rock, he finds all kinds of ways to use it. He prefers a larger enclosure,( he went off feed in a small short tub and rubbed his nose bad), just as the BP gets the short tub. It's what mine prefer.
