Mourning Gecko Care Sheet: The Full Reference

Quick answer: Mourning geckos need a tall 12"x12"x18" minimum enclosure, generally no dedicated heat source, 60–80% humidity from daily misting, and a complete MRP diet offered 3–4 nights a week — one of the lower-maintenance popular pet reptiles once set up correctly.
Enclosure minimum12"x12"x18"
Humidity60–80%
Heat sourceUsually not needed
Lifespan5–8 years

Housing

12"x12"x18" minimum, taller and more vertical space favoured over floor space, well ventilated, packed with cork bark and climbing branches.

Temperature

Normal room temperature (75–82°F) works for most homes — no basking bulb or heat mat usually needed. Watch for heat stress above ~82°F.

Humidity

60–80%, maintained through misting once or twice daily, with good ventilation to prevent stagnant dampness.

Diet

A complete MRP powder mixed with water, offered 3–4 nights a week, is nutritionally sufficient alone. Insects are optional enrichment.

UVB

Not strictly mandatory, but low-level (2–5%) increasingly recommended as good practice.

Common beginner mistakes

Undersized or too-wide enclosures, unnecessary heat lamps causing heat stress, running too dry, and reaching for standard-sized feeder insects instead of fruit flies or pinhead crickets, which are too large for this tiny species.

Mourning Gecko Enclosure: What You Actually Need

A single adult mourning gecko needs a minimum 12"x12"x18" front-opening, well-ventilated enclosure — taller matters more than wider since this species is highly arboreal — furnished with cork bark, branches, and dense foliage for climbing.

Mourning Gecko Setup Checklist: Everything Before Day One

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.

Mourning Gecko Tank Size Guide: By Age

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 Gecko Heating: Why You Probably Don't Need Any

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.

Mourning Gecko UVB: Is It Actually Necessary?

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 Gecko Humidity: Why It Needs to Be High

Mourning geckos need roughly 60–80% humidity, achieved through misting once or twice daily, with good ventilation to prevent the dampness from turning stagnant.
