The Perfect Enclosure

Creating the right environment is the single most important thing you can do for your crested gecko's long-term health and happiness. Thankfully, cresties are forgiving companions — but they still have clear preferences worth honoring.

Enclosure Size

Adult crested geckos thrive in tall, vertically oriented enclosures. A single adult requires a minimum of 40 gallons (typically an 18" × 18" × 36" front-opening terrarium). Bigger is always better — more vertical height means more climbing enrichment.

Juveniles (under 6 months): 12" × 12" × 18"
Sub-adults (6–12 months): 18" × 18" × 24"
Adults: 18" × 18" × 36" or larger

Temperature & Humidity

Crested geckos are cool-to-moderate temperature animals. They do not require a heat lamp in most home environments.

Daytime temperature: 72–78°F (22–26°C)
Night-time temperature: Can drop to 65°F (18°C) safely
Humidity: 60–80%, with a daily dry-out period to prevent respiratory issues

Mist one side of the enclosure each evening and allow it to partially dry before the next misting.

Avoiding Overheating

Temperatures above 85°F (29°C) are dangerous and can be fatal. Keep enclosures away from direct sunlight and heat vents.

Substrate

A naturalistic bioactive substrate works well and holds humidity beautifully:

Coconut fiber mixed with organic topsoil
Ready-made bioactive mixes (e.g., Josh's Frogs BioBedding)
Paper towels for quarantine or juveniles

Lighting

Crested geckos are crepuscular (active at dawn and dusk). A low-output UVB bulb (5.0) on a 12-hour cycle supports bone health, though it is not strictly required if dietary calcium is adequate. A simple day/night cycle helps regulate their natural rhythms.

Furnishings

Add plenty of climbing opportunities and hiding spots:

Cork bark rounds and flats for hides and climbing
Sturdy live or artificial plants (Pothos, Ficus, Bromeliads)
Horizontal branches at mid and upper levels
A water dish at the bottom for supplemental hydration
