Corn snake care guide
Pantherophis guttatus
An active, curious colubrid that both climbs and burrows. Height is genuinely used, so don't treat a corn snake as a pure floor-dweller.
Semi-arboreal — floor space plus climbing
Corn snake enclosure size
Semi-arboreal — floor space plus climbing. An adult corn snake should live in at least 48" L × 24" W × 24" H; we build toward 60" L × 24" W × 30" H (5 × 2 × 2.5 ft, roughly 10 sq ft of floor and about a 187-gallon glass equivalent).
Corns are escape artists — every lid and door must latch.
- Hatchling / baby
- 30" L × 12" W × 16" H recommended · min 20" L × 10" W × 12" H
- Juvenile
- 36" L × 18" W × 18" H recommended · min 30" L × 12" W × 16" H
- Adult
- 60" L × 24" W × 30" H recommended · min 48" L × 24" W × 24" H
Temperature and heating
Halogen basking bulb over one end, thermostat-controlled.
- Basking / warm surface
- 88–90°F surface
- Warm side (ambient)
- 82–86°F ambient
- Cool side (ambient)
- 70–75°F ambient
- Night
- 65–72°F is fine
Lighting and UVB
UVB: T5 UVB 5–6% over the warm end (UVI 2–3 at basking height). Run lights on a 12–14 hours in summer, 10 in winter photoperiod, on a timer, and replace UVB bulbs on the manufacturer's schedule even while they still emit visible light.
Humidity
Target 40–60%. One large water bowl; raise briefly during shed with a humid hide.
Substrate and depth
Aspen shavings or a soil/sand/coco mix. Depth: 2–4 in.
Enclosure tips and furnishing
- Warm and cool hides
- Sturdy branches and vertical cork
- Water bowl
- Leaf litter and clutter to break sightlines
Build list
- Front-opening 4ft enclosure — Easier access and better sightlines than a top-opening tank.
- Halogen basking bulb + dimming thermostat — Creates a real surface-temperature gradient.
- Digital thermostat — Every heat source must run through a thermostat — unregulated heat burns animals.
- Two digital probe thermometers + hygrometer — Read the warm side, cool side and humidity directly — stick-on dials are inaccurate.
- Aspen or bioactive soil mix — Corn snakes burrow; loose substrate at depth matters.
- Climbing branches — They use vertical space nightly.
