Leachianus Gecko Enclosure Requirements
Leachianus Geckos are large, arboreal geckos that require more space and more substantial climbing structure than Crested or Gargoyle Geckos. Getting the enclosure right from the start is particularly important given the cost of the animal and the length of the commitment.
Enclosure Size
A 24" × 24" × 24" enclosure is a reasonable minimum starting point for a single adult Leachianus Gecko, with larger enclosures preferred, particularly for larger individuals. Leachianus Geckos vary considerably in size by locality — a smaller island animal and a large mainland animal have meaningfully different space requirements.
Juveniles can be started in appropriately sized smaller enclosures and moved up as they grow, making monitoring and husbandry management easier in the early stages.
Height matters. Leachianus Geckos are semi-arboreal and will use vertical space, but they are heavier-bodied than Crested Geckos and spend more time in the mid-to-lower levels of the enclosure. Prioritize width and depth alongside height.
Enclosure Type
Front-opening enclosures are strongly preferred because access from the front can make routine interaction less disruptive and easier to manage. PVC or aluminum-framed enclosures are practical for their durability and moisture resistance. Glass terrariums work but can be heavier and less forgiving of humidity cycling.
A secure locking mechanism is essential. Leachianus Geckos are powerful and will push against doors and lids.

Climbing Structure
Leachianus Geckos need substantial, sturdy climbing structure. Cork bark tubes large enough for the animal to fully enter are among the most useful furnishings — they serve as an excellent hide and climbing structure. Thick branches, cork flats, and dense cover complete the setup. Avoid thin perches that cannot support the gecko’s weight.

Hides
Provide at least one secure hide large enough for the animal to fully conceal itself. A cork tube of appropriate diameter is the most natural and practical option. Leachianus Geckos are secretive and will spend much of the day hidden — a gecko that stays hidden during daylight hours is behaving normally.
Substrate
Coconut fiber, organic topsoil, or a bioactive mix are all appropriate. A bioactive substrate with springtails and isopods reduces maintenance and supports live plants. Aim for 2–3 inches where loose substrate is used, providing moisture retention and supporting plants and the bioactive system.

Plants
Live or artificial plants provide cover, reduce stress, and improve enclosure aesthetics. Live plants also contribute to humidity stability. Pothos, bromeliads, and ficus are commonly used in humid New Caledonian gecko enclosures. Ensure any live plants are non-toxic and free of pesticides.
Temperature and Humidity
Aim for 72–78°F ambient temperature. Avoid sustained temperatures in the low-to-mid 80s or higher. Target 60–80% humidity with a daily dry-down cycle — mist in the evening and allow partial drying before the next session.

UVB Lighting
Low-output UVB is increasingly recommended as best practice. Provide low-output UVB appropriate for a shaded/arboreal species, with the fixture and distance selected to produce an appropriate exposure at the animal’s accessible basking and perching areas. Provide a photoperiod of approximately 12 hours light and 12 hours dark.

Cleaning and Maintenance
Spot-clean waste as needed. Replace food and water dishes daily. In a bioactive setup, deep cleans are less frequent — the cleanup crew handles waste breakdown. In non-bioactive setups, replace substrate and perform deeper cleaning as needed based on waste accumulation, odor, moisture, and enclosure condition.
