What size tank does a crested gecko need?

Adult crested geckos need a minimum 18x18x24 inch tall enclosure. Bigger (24x18x36) is better. Always choose vertical (tall) enclosures — crested geckos are arboreal and need height, not floor space.

What temperature do crested geckos need?

Crested geckos thrive at room temperature: 72-78°F. Temperatures above 82°F cause heat stress and can be fatal. Most homes need no supplemental heating. Nighttime drops to 65-72°F are fine and beneficial.

Do crested geckos need live insects?

Crested geckos can survive on CGD (crested gecko diet like Pangea or Repashy) alone, but offering live insects 1-2 times per week provides enrichment, exercise, and additional protein. Small discoid roach nymphs, silkworms, and BSFL are the best options.

Crested Gecko Enclosure Setup: The Complete Guide

Crested Gecko Enclosure Setup: Complete Guide

Crested geckos (Correlophus ciliatus) are one of the easiest reptiles to keep — no special lighting, no high temperatures, no complicated heating systems. But easy does not mean effortless. The enclosure still needs to be set up correctly for your crested gecko to thrive, display natural behavior, and live its full 15-20 year lifespan.

Enclosure Size and Type

Age	Minimum Size	Notes
Hatchling/Juvenile	12x12x18 inches	Small enclosure prevents stress from open space
Sub-adult (6-12 months)	18x18x24 inches	Can move directly to adult size if heavily planted
Adult (12+ months)	18x18x24 minimum	24x18x36 or larger is ideal for adults

Crested geckos are arboreal — they need vertical space, not floor space. Always choose tall enclosures over wide ones. Front-opening glass terrariums (Exo Terra, Zoo Med) are the standard. PVC enclosures work well if they have adequate ventilation — crested geckos need airflow to prevent respiratory issues from stagnant humid air.

Temperature

Crested geckos thrive at room temperature — one of their biggest advantages as pets.

Ideal range: 72-78°F
Maximum: 82°F — temperatures above 82°F for extended periods cause heat stress and can be fatal
Nighttime drop: 65-72°F is fine and beneficial
Heating: Most homes need no supplemental heating. If your room drops below 65°F consistently, use a low-wattage ceramic heat emitter on a thermostat. Never use heat mats on the side of a crested gecko enclosure — they create dangerous hot spots on climbing surfaces.

Humidity

Crested geckos need a humidity cycle — not constant high humidity.

Mist heavily at night: Spike humidity to 80-90% in the evening
Let it dry during the day: Daytime humidity should drop to 50-60%
This wet/dry cycle prevents: Respiratory infections (from constant dampness) and stuck shed (from constant dryness)
Misting system: An automatic misting system (MistKing, Monsoon) is the most reliable method. Manual spray bottles work but require twice-daily commitment.

Substrate and Bioactive Setup

Crested geckos are ideal candidates for bioactive enclosures — they produce small amounts of waste, live at moderate temperatures, and their humidity requirements support tropical plant growth.

Simple option: Paper towels (easy cleanup for juveniles) or coconut fiber
Better option: ABG mix (tree fern fiber, charcoal, sphagnum moss, orchid bark, peat) — the standard bioactive substrate
Cleanup crew: Tropical isopods and springtails. Powder Blue isopods and Powder Orange isopods are excellent starter species — they thrive at crested gecko humidity and temperatures, consume waste and mold, and reproduce readily in bioactive setups.

Plants and Decor

Fill the enclosure vertically with climbing opportunities:

Live plants: Pothos, bromeliads, ficus, dracaena, philodendron — all thrive at crested gecko conditions and provide cover, climbing surfaces, and humidity retention
Cork bark tubes and flats: Essential climbing surfaces and hiding spots
Bamboo poles: Horizontal and diagonal perching
Leaf litter (bottom): Magnolia or oak leaves provide ground cover for cleanup crew and naturalistic appearance

Feeding

Crested geckos are omnivores — they eat both fruit-based diets and live insects.

Crested gecko diet (CGD): Pangea or Repashy mixed with water, offered in a small elevated dish. Replace every 24-48 hours. This is the dietary staple.
Live insects: Offer 1-2x per week for enrichment and protein. Best options:
- Small discoid roach nymphs — high protein, no climbing, no biting
- Small silkworms — soft, low-fat, easy to digest
- Small BSFL — calcium-rich, no dusting needed
Dust insects with calcium + D3 powder before offering
Avoid: Mealworms (tough chitin), large crickets (bite sleeping geckos), superworms (too large and high-fat)

Lighting

Crested geckos are crepuscular — most active at dusk and dawn. They do not require UVB for survival, but low-level UVB (5% T5 bulb) supports vitamin D3 synthesis and has been shown to improve bone density and natural behavior. If your enclosure has live plants, you will need a plant-growth light anyway — a 6500K LED with a low-output UVB bulb covers both needs.

Common Crested Gecko Setup Mistakes

Enclosure too hot: Above 82°F is dangerous. Crested geckos are cool-weather animals.
Constant high humidity: Causes respiratory infections. The wet/dry cycle (mist at night, dry during day) is critical.
Empty enclosure: Crested geckos need dense foliage and climbing surfaces to feel secure. An empty tank with one hide causes chronic stress.
Floor-level food dish: Crested geckos are arboreal — place food dishes elevated on magnetic ledges or suction cups.
No insect supplementation: CGD alone sustains crested geckos, but occasional live insects provide enrichment, exercise, and additional protein that improves body condition.
