The complete beginner's guide to crested gecko care — enclosure setup, feeding, temperature, humidity, and the mistakes every new owner makes.
Crested geckos are one of the easiest reptiles to keep. They eat powdered food mixed with water, they thrive at room temperature, and they were literally thought to be extinct until 1994. Every pet crested gecko alive today descends from animals rediscovered on a tiny island during a tropical storm.
But "easy" doesn't mean "no research needed." The difference between a crested gecko that lives 5 years and one that lives 20 comes down to a few key decisions. This guide covers all of them.
Crested geckos are arboreal. They live in trees. This means their enclosure needs to be tall, not long. The opposite of leopard geckos and most ground-dwelling reptiles.
Hatchlings (under 10g): Small setup, 8x8x12 inches. Babies get overwhelmed in large spaces and may stop eating. Small and cozy works best.
Juveniles (10-20g): 12x12x18 inch enclosure.
Adults (35g+): 18x18x24 inches minimum. Bigger is always better for established adults. A 24x18x36 is ideal if you have the space.
Front-opening glass terrariums with screen tops are the standard. The glass holds humidity while the screen provides ventilation.
Crested geckos need things to climb. Branches, cork bark tubes, vines (live or artificial), and plants create a three-dimensional playground. Your gecko should be able to reach every level of the enclosure without touching the ground.
Live plants (pothos, bromeliads, ferns) add humidity, look amazing, and give your gecko sleeping spots on leaves. They also provide drinking surfaces after misting.
Always include at least two hides. One higher up, one lower. A gecko with nowhere to hide is a stressed gecko.
Paper towels for beginners and babies. Easy to clean, easy to monitor health. Coconut fiber for adult setups. Bioactive substrate (topsoil mix with springtails and isopods) for the gold standard long-term setup.
Avoid: reptile carpet (bacteria trap), sand (impaction risk), anything with fertilizers.
Crested geckos thrive between 72-78°F (22-26°C). Most homes are naturally in this range. Night drops to 65-72°F are fine and actually beneficial.
The critical rule: Never let temperatures stay above 80°F. Above 85°F can be lethal. Heat stress is the number one killer of crested geckos. If your home gets warm in summer, air conditioning isn't optional.
Most crested gecko owners don't need any supplemental heating. If your house runs cold (below 68°F consistently), a low-wattage ceramic heat emitter on a thermostat works well.
This is the one area that requires actual daily effort.
Target: 60-80% after misting, dropping to 40-50% between mistings. This wet-dry cycle is critical. Constant high humidity causes mold and respiratory infections. Constant low humidity causes stuck sheds and dehydration.
The routine: Mist the enclosure thoroughly once or twice daily, usually in the evening when your gecko is waking up. Mist the walls, plants, and decorations. The enclosure should be visibly wet after misting and dry within 4-6 hours.
Always provide a shallow water dish as well. Some geckos drink from dishes, others prefer licking droplets off plants and glass.
Invest in a digital hygrometer ($10-15). Analog ones are inaccurate. Check daily until you've dialed in your routine.
This is where crested geckos really shine as beginner pets.
Pangea and Repashy make nutritionally complete powdered diets. Mix with water to a smoothie consistency, put it in a small dish on an elevated ledge. That's it. Your gecko can live a full, healthy life eating only this.
Schedule: Fresh food every evening for babies, every other evening for juveniles, 2-3 times per week for adults.
Pangea Fig & Insects is the most universally accepted flavor. If your gecko refuses food, try switching flavors before worrying.
Live crickets or Dubia roaches 1-2 times per week provide enrichment and extra protein. Dust with calcium + D3 powder. Size rule: no wider than the space between your gecko's eyes.
Not required, but recommended especially for growing juveniles.
Caused by calcium deficiency. Signs: wobbly walking, soft jaw, kinked spine. Almost entirely preventable with proper diet (Pangea and Repashy are calcium-fortified).
Retained skin on toes, tail, or eyes. Usually a humidity problem. Increase misting, provide a humid hide with damp sphagnum moss. For stubborn stuck shed on toes, soak in lukewarm water and gently remove with a damp cotton swab.
Crested geckos can drop their tail when stressed. Unlike leopard geckos, it does NOT grow back. The gecko lives a perfectly normal life without it. Handle gently, never grab the tail.
Signs: wheezing, bubbles around nose, labored breathing. Caused by constantly high humidity with poor ventilation. Requires vet treatment with antibiotics.
1. Keeping the enclosure too hot. Above 80°F sustained is dangerous. Monitor with a digital thermometer.
2. Not letting the enclosure dry out between mistings. The wet-dry cycle prevents mold and respiratory issues.
3. Too large an enclosure for babies. Small geckos in big tanks can't find food and stress out.
4. No thermometer or hygrometer. "It feels fine" is not monitoring. Spend $10 on digital instruments.
5. Handling too soon. Wait at least 2 weeks after bringing your gecko home before first handling. Let them settle in.
Crested geckos are ideal if you want a reptile that:
They're not ideal if you want a pet that's active during the day (they're nocturnal) or one that seeks out affection (they tolerate handling, they don't crave it).
