Mourning Gecko Enclosure: What You Actually Need
| Minimum size (adult) | 12"x12"x18" |
| Orientation priority | Height over floor space |
| Heat source needed? | Usually not — room temp works |
Height over floor space
Mourning geckos are highly arboreal and spend nearly all their time off the ground climbing branches and foliage. A tall, vertically oriented enclosure (12"x12"x18" minimum, 16"x16"x24" or larger increasingly standard) suits them far better than a wide, low tank — floor space matters much less here than for a ground-dwelling species.
Ventilation matters as much as size
Good airflow — mesh sides or a well-ventilated screen top — keeps the humidity this species needs from tipping into stagnant, mould-prone dampness. A largely sealed glass enclosure works against the humidity balance rather than helping it.
No heat source required in most homes
Unlike many popular reptile pets, mourning geckos generally do best at normal room temperature and can suffer heat stress above roughly 82°F. Most keepers need no basking bulb or heat mat at all, which simplifies the enclosure considerably compared to a basking species.
Furnishing essentials
Cork bark rounds and flats, grapevine or manzanita branches, and dense foliage (live or artificial) fill out the vertical space this species actually uses. A shallow water dish and a mid-height feeding ledge for the MRP dish round out a functional setup.

A complete mourning gecko setup needs a tall 18"+ front-opening enclosure, cork bark and branches for climbing, coco fibre/moss substrate, a misting routine to hold 60–80% humidity, and complete MRP powder — no heat lamp is required in most homes.
Hatchlings can start in a small (roughly 5"x5"x8") enclosure to make food easier to find, juveniles move up around a few months old, and adults need a minimum 12"x12"x18" vertical enclosure.
Mourning geckos generally do best at normal room temperature, roughly 75–82°F, and can suffer heat stress above about 82°F. Most homes need no basking bulb or heat mat at all — just monitoring during hot weather.
Low-level UVB (roughly 5–6% output) is increasingly recommended as good practice, though it isn't strictly mandatory for mourning geckos the way it is for a strongly basking desert species — their diet's built-in D3 from MRP covers much of the gap.
Mourning geckos need roughly 60–80% humidity, achieved through misting once or twice daily, with good ventilation to prevent the dampness from turning stagnant.
Mourning geckos commonly live 5–8 years in captivity with correct husbandry, occasionally more — a notably long lifespan for a small gecko and a genuine long-term commitment.
