Common questions

What size enclosure does a garter snake need?

At least 48 × 24 × 24 inches (122 × 61 × 61 cm) for one adult, about 120 gallons. Floor space matters more than height for this species. Bigger is always better if you have room.

What temperature should a garter snake enclosure be?

Aim for a warm side of 85-90°F and a cool side of 75-80°F, so it can move between the two to control its body temperature. Check with a digital probe thermometer, not a stick-on dial.

What humidity does a garter snake need?

40-60%. A digital hygrometer in the middle of the enclosure gives the most useful reading.

Does a garter snake need UVB?

Yes, Zone 2, which means moderate UVB, for animals that bask now and then. Match your bulb and its distance to that level using the maker's chart, and replace it on schedule.

Which common tanks fit an adult garter snake?

Of the common sizes, these meet the adult minimum: 4 × 2 × 2 (120 gallon) (48 × 24 × 24 in), 4 × 2 × 4 tall (48 × 24 × 48 in), 6 × 2 × 2 (72 × 24 × 24 in), 6 × 3 × 4 (72 × 36 × 48 in), 8 × 4 × 4 (96 × 48 × 48 in).

These are common hobbyist guidelines for a healthy adult, based mostly on published species care guides. Babies, sick animals and specific localities can need different setups, so check with a reptile vet for anything serious.
