Enclosure/ Vivarium Size Relation

If you look at the enclosure and think that it looks too small for the size of your snake, then it most probably is. At a very minimum, the smallest tank for a corn snake is 20 gallons. For example a 40 gallon tank would give your adult corn snake a much happier life, which more space for it to roam around freely. The happiness of a corn snake should be at the forefront of every owners mind.

A 36” x 18” x 17” enclosure would be an ideal size for your adult corn snake. This would give the snake twice as much room as the recommended minimum and has the space to incorporate come branches for your snake to climb up and along. 

The size of cage has no limit really. However the problems come when trying to keep the enclosure clean, and at a suitable temperature for your corn snake. Monitoring temperature can then become a struggle as the enclosure needs to sty at a constant. You also don’t want an enclosure that will take all day to properly clean out. No one realistically has that much time on their hands, or the patients .So more than likely it will be rushed, and not up to the standard that it should be.
