Crested geckos are one of the best starter reptiles on the market — and for good reason. They’re hardy, handleable, don’t need UV lighting, and thrive at room temperature in most homes. If you’re just getting started, this guide covers everything you need to set up a healthy enclosure and keep your gecko thriving long-term.

What Makes Crested Geckos Good for Beginners?

Unlike many reptiles, crested geckos are remarkably forgiving. They tolerate a range of temperatures, eat a commercially prepared diet, and don’t require the complex lighting setups that bearded dragons or chameleons demand. They’re also active in the evening, which makes them interesting to watch without requiring you to be home all day.

They do have specific needs — no reptile is truly low-maintenance — but those needs are straightforward once you understand them.

Setting Up the Enclosure

Size and Type

A single adult crested gecko needs a minimum of a 20-gallon tall enclosure. Crested geckos are arboreal, meaning they live and move vertically, so height matters more than floor space. A 18” x 18” x 24” enclosure is the sweet spot for one adult.

For juveniles under 10 grams, start smaller — a 6-quart plastic tub or 10-gallon tank prevents them from having trouble locating food.

The Exo Terra 18x18x24 Glass Terrarium is a popular choice and purpose-built for arboreal species. It has front-opening doors, a screen top for ventilation, and a raised bottom for a drainage layer.

Substrate

Coco fiber, bioactive soil mixes, or paper towels all work. For beginners, a simple coco fiber substrate holds humidity well and is easy to replace. Avoid calcium sand or reptile carpet — both cause problems.

A 2–3 inch substrate layer is sufficient. Spot clean weekly and do a full replace every 2–3 months.

Hides and Climbing

Add at least two hides — one on the warm side, one on the cool side. Crested geckos also need vertical climbing space: cork bark tubes, bamboo, and sturdy artificial plants all work well. Live plants like pothos and bromeliads are excellent if you go bioactive.

Don’t overcrowd the enclosure, but don’t leave it bare either. A gecko with nowhere to hide is a stressed gecko.

Temperature and Humidity

Temperature

Crested geckos do best between 68–78°F (20–26°C). Anything above 80°F for extended periods causes heat stress and can be fatal. Most homes in this range require no additional heating — just avoid placing the enclosure near radiators or in direct sunlight.

If your home drops below 65°F at night, a low-wattage ceramic heat emitter on a thermostat will keep temperatures stable without disrupting their night cycle.

Humidity

Target 60–80% humidity with a dip to around 50% during the day. This mimics the natural wet/dry cycle of their native New Caledonia. Mist the enclosure once or twice daily — once in the evening when they become active, and once in the morning if needed.

A digital hygrometer is essential. The Govee Bluetooth Hygrometer is inexpensive and lets you monitor humidity from your phone, which is handy when you’re starting out and trying to dial in your routine.

Feeding

Crested Gecko Diet (CGD)

The easiest and most complete diet for crested geckos is a commercially prepared meal replacement powder mixed with water. Repashy and Pangea are the two most trusted brands in the hobby.

Mix to a ketchup-like consistency and offer every other day in a small dish. Remove uneaten food after 24–36 hours to prevent mold.

The Pangea Fruit Mix Complete is a solid starting point — it’s nutritionally complete and most geckos accept it readily.

Live Insects

Supplementing with live insects 1–2 times per week improves growth, breeding success, and enrichment. Small crickets and dubia roaches sized to the gecko’s head width are ideal. Dust insects with calcium powder at every feeding and a multivitamin every 2 weeks.

Juveniles benefit more from insects than adults. An adult gecko maintained entirely on CGD will do fine, but insects keep them engaged and support long-term health.

Water

Misting provides most of their hydration, but keep a small shallow water dish in the enclosure at all times. Change it every 1–2 days.

Handling

Give a new gecko 2 weeks to settle in before attempting to handle it. After that, start with short 5-minute sessions and build up gradually.

Crested geckos can drop their tails if stressed — unlike leopard geckos, the tail does not grow back. It’s not dangerous to the gecko, but it’s worth knowing. Most captive-bred geckos are quite handleable once they’re comfortable with you.

Never grab from above — this mimics a predator attack. Instead, let the gecko walk from hand to hand, moving your lower hand to the top in a continuous motion.

Health: What to Watch For

Healthy crested geckos are alert in the evenings, have full rounded bodies (especially at the base of the tail), and eat consistently. Warning signs include:

  • Sunken eyes or visible hip bones — dehydration or malnutrition
  • Floppy jaw or rubbery limbs — metabolic bone disease from calcium deficiency
  • Lethargy during active hours — temperature issue or illness
  • Wheezing or mucus around the mouth — respiratory infection

If you notice any of these, consult a reptile vet. MBD and dehydration caught early are treatable. Left unaddressed, they’re fatal.

What You’ll Spend to Get Started

A realistic starter budget looks like this:

  • Enclosure: $80–$150
  • Thermometer/hygrometer: $15–$25
  • Substrate and décor: $30–$50
  • CGD food (3-month supply): $20–$30
  • Gecko: $50–$150 depending on morph

Total: roughly $200–$400 to do it properly. Cutting corners on enclosure size or humidity monitoring tends to create vet bills later.

FAQ

Do crested geckos need UV lighting? No — they’re crepuscular and were long thought to need no UV. Recent research suggests low-level UVB may be beneficial, but it’s not required. A 2.0 or 5.0 UVB bulb on a 10-hour cycle won’t hurt and may improve long-term health.

Can I keep two crested geckos together? Two females can cohabitate in a large enough enclosure. Never house two males together. Male-female pairs will breed constantly, which stresses the female. Beginners are better off keeping one gecko per enclosure.

How long do crested geckos live? 15–20 years in captivity with proper care. This is a long-term commitment.

How do I know if my gecko is eating? Check the food dish after 24 hours — if the level has dropped, they’re eating. Crested geckos feed at night, so you may rarely catch them in the act.

What’s the best beginner morph? Flame or harlequin morphs are widely available, reasonably priced, and just as hardy as wild-type geckos. Don’t pay a premium for rare morphs until you’re comfortable with the basics.
