Crested Gecko Enclosure Guide

Crested geckos are arboreal reptiles native to the tree canopies of New Caledonia. They climb, jump, and perch at height — this is not optional behavior, it is their entire lifestyle. A horizontal tank forces them to live on the ground, which causes chronic stress, suppresses natural behavior, and leads to health problems over time.

• Height must exceed width and depth — TALL orientation only
• Front-opening doors are strongly preferred for easy access and less stress
• Horizontal tanks marketed for other reptiles are not suitable for crested geckos
• The builder blocks horizontal enclosure selections automatically

An empty tall tank is wasted space. Crested geckos need a three-dimensional environment with climbing routes from bottom to top. Think of the enclosure as a vertical forest, not a floor plan.

• Cork bark flats and tubes mounted vertically at multiple heights
• Vines and branches creating climbing highways from bottom to top
• Live or artificial foliage providing cover at upper, middle, and lower levels
• Magnetic ledges and feeding platforms at mid to upper heights
• Ensure the gecko can reach every level without falling — no dead-end perches

• Juveniles (under 15g): 12"x12"x18" minimum — upgrade as they grow
• Sub-adults (15-25g): 18"x18"x24" minimum tall enclosure
• Adults (25g+): 18"x18"x24" minimum, 18"x18"x36" recommended
• When in doubt, go larger — crested geckos actively use all vertical space provided
• Upgrade enclosure size as the gecko grows — do not keep adults in juvenile tanks

Male crested geckos are territorial and will fight when housed together. Injuries from cohabitation fights can be severe and are often fatal. Even in large enclosures, males will compete for territory and resources.

• Two males in one enclosure will fight — this is not optional behavior
• One male + one female risks unwanted breeding and female stress
• Two females can sometimes cohabitate but stress and competition still occur
• One gecko per enclosure is always the safest and recommended approach

Glass front-opening terrariums are the gold standard for crested geckos. They retain humidity for the wet/dry cycle, provide excellent visibility, and are available in proper tall dimensions from Exo Terra, Zoo Med, and similar brands.

• Glass terrariums retain humidity between mistings — essential for the wet/dry cycle
• Front-opening doors reduce stress compared to top-opening tanks
• Full screen enclosures lose humidity too quickly and are hard to heat
• Partial screen tops on glass tanks provide ventilation while retaining humidity
