Cornsnakes are one of the most popular snakes among beginner and veteran keepers alike.

Enclosure

Cornsnakes will do well in various enclosure types, including tanks, tubs, racks, and PVC. While they are a terrestrial snake, they do have the tendency to climb more than most other terrestrial species and will appreciate any enrichment that encourages this behavior.
They typically make use of every inch offered to them,
so having adequate space is also important.
The outline below lists various enclosure dimensions
for each stage of your Cornsnake’s life.


Tanks
Hatchlings: 10gal. (10in. x 20in. x 12in.)
Juveniles and sub-adults: 20gal. (30in. x 12in. x 12in.)
Adults: 40gal.+ (36in. x 18in. x 12in.)

 

Standalone Tubs
Hatchlings: 6qt. (14in. x 7in. x 4in.)
Juveniles and sub-adults: 32qt. (23in. x 16in. x 6in.)
Adults: 52qt.+ (35in. x 16in. X 6in.)

Racks
The following racks and dimensions are based off of Reptile Basics rack systems:

Hatchlings: I160 Hatchling tubs (12.75in. x 6.25in. x 1 15/16in.)
Juveniles and sub-adults: 23qt. VE-2 and VE-6 tubs (22.44in. x 14.76in. x 4.25in.)
Adults: 45qt. VE-Super70 tubs (33in. x 18in. x 5.28in.)

PVC
PVC enclosures are mostly recommended for sub-adults and adults due to their larger size. While you may have a smaller custom-built PVC enclosure made, most commercial sizes are more suitable for sub-adult and adult snakes. The recommended size dimensions for adult Cornsnakes is at least 34in. x 18in. x 9in.

Please remember that there are numerous ways to keep any species of snake. These dimensions are for use as a general guide only. It is up to you as the keeper to decide which size is best suited for your snake.


Substrate and Humidity
Cornsnakes require relatively low humidity, thriving between 45-50%, or 55% while in shed. For substrate, it is suggested to use aspen shavings or aspen chips, which can be located at just about any pet store that carries exotic animal supplies or various online stores such as Amazon. Alternatively, if you struggle to keep humidity levels above 40%, you can use moisture-retaining substrates such as cypress mulch to help better maintain humidity. Substrate should be at least an inch deep, although 2-3 inches is better for adults so they are able to burrow if they please.

Heating
You can use a variety of different heat sources for Cornsnakes depending on your setup. Cornsnakes require a warm spot of about 85°F and a cool spot no cooler than 75°F. You can achieve this by using a UTH (under tank heater) beneath your tank or tub, heat tape, CHE (ceramic heat emitter), DHP (deep heat projector), or RHP (radiant heat panel). While UVB and UVA light is not necessary for most species of snakes, it is encouraged as it has shown to be beneficial for them when provided.

Feeding
Hatchling and juvenile Cornsnakes should be fed once every 5-7 days. Hatchlings will typically begin on extra small pinky mice. The size of the feeder can be easily gauged by simply examining the widest part of your snake’s body and feeding no larger than ½ in. than this size. For hatchlings and juveniles, you can alternatively feed 10% of your snake’s body weight, although this number is not as accurate for adult Cornsnakes. Your snake should be able to ingest the feeder with relative ease. Adult Cornsnakes typically eat one large mouse once every 10-14 days to maintain a healthy body condition, but frequency will vary depending on the individual snake and its metabolic needs.

Enrichment
Cornsnakes are active and inquisitive snakes that do well with many forms of enrichment. Offering cork bark, rocks, and foliage are great for textural stimulation. Branches, PVC pipes, and ledges make for great climbing opportunities as long as they are placed relatively low to the ground to prevent your snake from hurting themselves. You can also offer dietary variety by including quail in their diet, if they will take to it. If you feed f/t, hiding the feeder to encourage hunting behavior is also recommended. They also benefit from time outdoors on a comfortably warm afternoon. That said, while there are various ways to offer enrichment to your snake, remember to be safe in doing so. Any outdoor items being added to the enclosure should be properly disinfected before use. All rocks and other similar items should be large enough that your snake can not ingest it. Do not feed reptiles to your snake. Other reptiles, rather they are wild caught or captive bred, can carry deadly diseases that are not worth transferring to your snake. If you take your snake outside, be sure your lawn is not treated with any toxic chemicals and monitor them closely so they are not captured by a nearby predator.

Other Essentials
Your Cornsnake will appreciate a water dish large enough for them to soak in when necessary. Some Cornsnakes prefer to soak in their water dish almost constantly while in shed, while others may avoid soaking altogether. You should also provide at least two hides for your Cornsnake to take refuge in, with one on the warm side and one on the cool side so they can properly thermoregulate. Remember to monitor your husbandry with an appropriate thermometer, thermostat and hygrometer.

In summary, Cornsnakes make wonderful companions and are especially ideal for new keepers due to their docile nature, simple care requirements and manageable size. As one of the most iconic snakes in the community, they will certainly be enjoyed by all for several years to come!
