Use this guide as a starting point alongside the detailed sources below. Health concerns, unexplained changes in behavior, or feeding problems belong with a reptile veterinarian.
Adult enclosure recommendation
Our recommended minimum: 1′ × 1′ × 18″ (30.5 × 30.5 × 45.8 cm), length × depth × height.
Preferred target: 18″ × 18″ × 2′ (45.8 × 45.8 × 61 cm), length × depth × height.
Usable internal space for 3 adult animals. Two or three adult Lepidodactylus lugubris; monitor resource access and plan separate hatchling accommodation.
Height is the usable internal envelope, including the space reserved for substrate and water. Check the remaining movement space and lamp clearance after installation.
Our preferred 18″ × 18″ × 2′ (45.72 × 45.72 × 60.96 cm) layout for the same two or three adults separates feeding and retreat sites. This is a functional editorial target, not a validated threshold.
ReptiFiles gives 1′ × 1′ × 18″ (30.48 × 30.48 × 45.72 cm) for two or three adults. Our preferred 18″ × 18″ × 2′ (45.72 × 45.72 × 60.96 cm) for the same group is an editorial choice to separate feeding and retreat sites. Volume alone does not justify increasing stocking.
- Floor space
- 1′ × 1′ (30.48 × 30.48 cm) usable footprint for a small group; no automatic volume-based stocking increases.
- Climbing space
- Fine branches, foliage and separate concealed resting and feeding locations.
- Substrate
- 2–3 in (5–8 cm) planting substrate over separately planned drainage where needed.
- Water
- Droplets and a very shallow accessible clean dish; protect tiny hatchlings from deep water.
- Security and ventilation
- Fine ventilated mesh and secured cable/door gaps sized for hatchlings, not adults.
Meeting these dimensions alone does not establish suitability. Check the usable layout, environmental conditions, equipment clearance and the individual animal’s requirements before occupation.

Reproduction and long-term care
Plan for offspring before acquiring mourning geckos. Females can reproduce without a male, so a supposedly single-sex group still needs population management. These small active climbers are best observed in a planted habitat. Maintain spare secure housing and reliable cultures of tiny feeders, and decide how future young will be responsibly housed.
Plan the whole group
Our recommended minimum for two or three adults is 1′ × 1′ × 18″ (30 × 30 × 46 cm), usable internal length × depth × height.
We prefer 18″ × 18″ × 2′ (46 × 46 × 61 cm) for the same small group as an editorial choice that makes separated feeding and resting sites easier to provide. It is not a validated welfare threshold or permission to add more geckos. Use fine branches, foliage and several covered routes. Hatchling housing is a separate temporary setup. Dimensions alone cannot prevent exclusion, escape or overheating; monitor individuals and have separation space ready. The stated height includes substrate and any drainage layer; retain safe lamp clearance at both branches and ceiling mesh.
Warmth, light and humid air
Provide an upper basking area at 80–85°F (27–29°C), a lower cool area at 70–75°F (21–24°C), and nights around 65–72°F (18–22°C). Read shaded air separately from warm surfaces. Offer daytime UVB (ultraviolet B) around UVI (ultraviolet index) 1–3 at the animal’s back with full shade and check the ceiling mesh, where geckos may approach a lamp more closely than on branches. Aim for ambient humidity around 60–70%, rising after misting and falling toward 50–60% as surfaces dry. Small habitats lose their cool refuge quickly.
Feeding adults and hatchlings
For an established adult group, a practical starting week has complete gecko food on two days and tiny gut-loaded, supplemented insects on three days. Adjust portions to observed intake and body condition. Hatchlings need reliably available fruit flies or pinhead crickets and closer feeding and hydration observation. Offer several feeding locations so a dominant animal cannot control the only cup. Coordinate calcium and vitamins with the complete diet and actual UVB exposure.

An observation project with extra logistics
Watch resource access and body condition rather than repeatedly catching animals for handling. A full head count does not prove each gecko has eaten. Record eggs, hatchlings and persistent displacement. Adults can eat hatchlings, so prepare separate accommodation before hatching. Do not peel firmly attached eggs off glass or furnishings. Never release surplus animals outdoors.
Decide what happens when eggs hatch
Map egg sites during ordinary maintenance and avoid disturbing attached eggs. Keep receiving housing, tiny feeders and an escape-resistant transfer method ready. Separate any animal that is injured or continually excluded. Seek experienced help with humane reproductive management if the colony is approaching your actual capacity; extra gallons are not a plan for unlimited offspring.
Where recommendations differ
Pangea reports five or six adults in 1′ × 1′ × 18″ (30.48 × 30.48 × 45.72 cm), whereas ReptiFiles starts with two or three. Neither is a controlled stocking-density study. We use the lower count to give small animals more opportunity to avoid each other. We do not adopt the ReptiFiles volume-only capacity calculation: usable routes, food access and aggression also matter. A larger group needs a new layout and management assessment rather than arithmetic alone.
Keep the tiny habitat serviceable
Use about 2–3 in (5–8 cm) of planting substrate when establishing plants, with drainage separately planned. Inspect cup holders, vents, door channels and removed cork for hidden geckos before carrying them away. Remove spoiled food, waste and standing dirty drainage water. Keep a backup feeder culture. A gecko losing condition, moving abnormally or repeatedly failing to shed needs an experienced reptile veterinarian. Keep clean shallow drinking water available as well as misting droplets.
