Tokay Gecko Enclosure Setup: Warm, Vertical, and Genuinely Humid
On This Page▾
Tokay gecko care runs warm and humid, closer to a rainforest setup than the arid conditions many other geckos prefer.
Enclosure Size
18 inches long by 18 inches wide by 36 inches tall as a minimum, larger is better. This is an arboreal species, so vertical space genuinely matters more than floor space. A front-opening enclosure makes maintenance easier given how defensive this species can be. House one gecko per enclosure, tokays are highly territorial.
Temperature
Basking area 90 to 105F, cooler zone 80 to 85F, and nighttime should stay warmer than many homes naturally run, 75 to 80F, not dropping below about 70F. Use a halogen basking bulb during the day, and pair it with a lightless ceramic heat emitter or deep heat projector on a thermostat for overnight warmth, this species genuinely needs supplemental night heat more than most.
Humidity: 60 to 80%, Not a Desert Setup
60 to 80% is the target range, considerably more humid than what suits a desert species. Achieve this with daily or twice-daily misting using a fine mist spray bottle, moisture-retentive substrate, sphagnum moss, and leaf litter. Good ventilation matters here too, high humidity without airflow invites mold.
A tokay gecko's basking area can run as hot as 105F, while its nighttime enclosure still needs to stay warmer than most homes naturally run, 75 to 80F, a combination that makes this one of the more demanding heating setups among commonly kept geckos.
Substrate
Coconut fiber or a bioactive-style mix, at least 2 to 3 inches deep, with moss and leaf litter layered on top. Avoid pine and cedar entirely, both release fumes that are toxic to reptiles.
Lighting
As a nocturnal species, tokays can technically survive without UVB if their diet supplies enough vitamin D3, but low-level UVB, a 5% or forest-strength T5 bulb, offers real benefit. Replace the bulb every 6 to 12 months. Keep nights genuinely dark.
The Non-Obvious Requirement: Climbing Structures at Every Level
Provide branches, cork bark, and foliage spanning the full height of the enclosure, not just near the top or bottom. This lets your tokay move along the vertical temperature gradient to thermoregulate properly.
If you're comparing this against a drier setup, our leopard gecko and African fat-tail tank setup guides show what a much less humidity-dependent enclosure looks like.

❓ Frequently Asked Questions
What size enclosure does a tokay gecko need?
18 by 18 by 36 inches as a minimum, and bigger is always better. Vertical space matters more than floor space for an arboreal species, and each gecko gets its own enclosure, since tokays are highly territorial.
What temperatures does a tokay gecko need?
A basking area of 90 to 105F, a cooler zone of 80 to 85F, and nighttime temperatures staying warmer than many homes naturally run, 75 to 80F, not dropping below about 70F.
How humid should a tokay gecko enclosure be?
60 to 80%, considerably more humid than what suits a desert species. This is achieved with daily or twice-daily misting, moisture-retentive substrate, sphagnum moss, and leaf litter, along with good ventilation so the humidity doesn't invite mold.
Does a tokay gecko need UVB?
Not strictly, since a nocturnal gecko can get its vitamin D3 from diet, but low-level UVB at 5% or forest strength brings real benefit. Swap the bulb every 6 to 12 months.
What substrate is safe for a tokay gecko?
Coconut fiber or a bioactive-style mix, 2 to 3 inches deep at least, topped with moss and leaf litter. No pine or cedar: the fumes are toxic to reptiles.
