Mourning Gecko Lifespan Factors: What Affects Longevity

Quick answer: Stable temperatures within the safe range, a consistent MRP-based diet, proper hydration, and avoiding chronic obesity are the biggest factors influencing a mourning gecko's lifespan — with good care, a 15–20 year lifespan is realistic, while chronic heat stress or poor diet can shorten it meaningfully.

Genetics play some role too, but husbandry consistency over the gecko's life tends to matter more than any single factor in isolation.

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.
