What Is the Best Crested Gecko Care Routine?
The best crested gecko care routine includes maintaining a stable temperature between 72°F and 78°F, humidity levels of 50–70% (with spikes to 80% at night), and feeding a balanced powdered diet like Repashy or Pangea every other day. For beginners, crested geckos are one of the easiest exotic pets to keep because they require no supplemental UVB lighting (though low-level UVB can be beneficial) and thrive in a simple 20-gallon vertical terrarium setup.
Quick Answer: Crested geckos need a 20-gallon tall terrarium, temperatures of 72–78°F, humidity of 50–70% (80% at night), and a powdered fruit diet fed every 48 hours. They are low-maintenance, beginner-friendly pets that do not require special UVB lighting if provided with a proper day/night cycle.
Crested Gecko Setup: The Essential Habitat
A proper crested gecko setup is the foundation of successful care. These arboreal lizards need vertical space to climb, with plenty of hiding spots and live or artificial plants. Here’s exactly what you need for a thriving enclosure.
Terrarium Size and Type
For a single adult crested gecko, use a 20-gallon tall terrarium (18 inches high minimum). Juveniles can start in a 10-gallon tank, but adults need more vertical room. Glass or PVC enclosures work best because they hold humidity. Screen lids are essential for ventilation, but avoid all-screen cages as they dry out too quickly.
- Minimum size for adults: 18 x 18 x 24 inches (20 gallons)
- Juvenile size: 12 x 12 x 18 inches (10 gallons)
- Best material: Glass terrarium with front-opening doors for easy access
Substrate and Decor
Use a moisture-retaining substrate like coconut fiber, sphagnum moss, or a bioactive mix. Avoid wood shavings or sand, which can cause impaction. Provide at least 3–4 inches of substrate to help maintain humidity. Add cork bark, bamboo tubes, and artificial or live pothos plants for climbing and hiding. Crested geckos are shy and need dense foliage to feel secure.
Temperature and Heating
Crested geckos are temperature-sensitive. The ideal ambient temperature range is 72–78°F. Nighttime drops to 65–70°F are safe. Do not let temperatures exceed 82°F, as heat stress can be fatal. Use a low-wattage ceramic heat emitter or a heat pad on the side of the tank if your room is cold. Never use heat rocks, which cause burns.
Humidity Management for Crested Geckos
Humidity is the most critical factor in crested gecko care. These geckos need high humidity for proper shedding and hydration. The goal is to maintain 50–70% humidity during the day, with a spike to 80% at night.
How to Achieve Correct Humidity
Mist the enclosure thoroughly with dechlorinated water every evening. The misting should be heavy enough to coat leaves and substrate but not create standing water. In most climates, one heavy misting per day is sufficient. In dry climates, you may need a second misting in the morning.
- Use a digital hygrometer to monitor humidity levels. Analog gauges are unreliable.
- Mist until you see water droplets on leaves and glass surfaces.
- Let humidity drop naturally during the day. If it stays above 70% constantly, increase ventilation.
- If humidity drops below 50%, mist again or use a reptile fogger on a timer.
Signs of Humidity Problems
Too little humidity causes stuck shed, especially on toes and tail tips. Too much humidity leads to bacterial infections and mold. Check your gecko’s skin after shedding: if any patches remain, increase misting frequency. If you see mold, reduce misting and improve airflow.
Lighting Guide for Crested Geckos
One of the biggest myths in crested gecko care is that they require UVB lighting. In reality, crested geckos are nocturnal and do not need UVB to synthesize vitamin D3. However, providing a low-level UVB bulb (2–5% UVB) can support overall health and natural behavior.
Do Crested Geckos Need UVB?
No, UVB is not required for crested geckos. They get all necessary vitamin D3 from their powdered diet. However, many keepers use a low-output UVB bulb (like Arcadia ShadeDweller or Zoo Med ReptiSun 2.0) to promote natural activity patterns. If you use UVB, provide plenty of shaded areas so your gecko can self-regulate.
Day/Night Cycle
Provide 12–14 hours of light per day. Use a simple LED or fluorescent bulb for plants and visibility. Avoid bright white lights at night. Crested geckos are most active at dusk and dawn, so use a dim red or blue night bulb if you want to observe them. Complete darkness at night is perfectly fine and actually preferred.
Lighting Tips for Live Plants
If you have live plants in your crested gecko setup, use a full-spectrum LED grow light. Pothos, bromeliads, and snake plants thrive under low to moderate light. Keep the light on a timer to maintain a consistent day/night cycle.
Crested Gecko Diet: What and How to Feed
Crested geckos are frugivores in the wild, eating fruit, nectar, and insects. In captivity, a complete powdered diet is the easiest and most nutritious option. Brands like Repashy Crested Gecko Diet and Pangea Fruit Mix contain all necessary vitamins, minerals, and protein.
Feeding Schedule
- Juveniles (under 1 year): Feed fresh food daily, remove after 24 hours.
- Adults (over 1 year): Feed every other day, remove after 24–48 hours.
- Amount: Mix 1 part powder to 2 parts water until it reaches a ketchup-like consistency. Offer a small dish (about the size of a bottle cap).
Insect Supplementation
While not required, offering live insects once or twice a month provides enrichment and extra protein. Crickets and dubia roaches are excellent choices. Dust insects with calcium powder (without D3) before feeding. Never feed wild-caught insects or mealworms, which are too hard to digest.
Water and Hydration
Always provide a shallow water dish with fresh, dechlorinated water. Crested geckos will also drink water droplets from leaves after misting. Change the water daily and clean the dish weekly to prevent bacteria growth.
Beginner Gecko Care: Common Mistakes to Avoid
New keepers often make these errors in crested gecko care. Avoid them for a healthy, stress-free pet.
- Overhandling: Crested geckos are display pets, not handling animals. Handle only 2–3 times per week for short periods (5–10 minutes).
- Incorrect temperature: Temperatures above 82°F can kill a crested gecko within hours. Always use a thermostat.
- Skipping humidity checks: Without a digital hygrometer, you cannot accurately gauge humidity. Buy one immediately.
- Using loose substrate for juveniles: Young geckos may ingest loose substrate. Use paper towels for the first 6 months.

Frequently Asked Questions About Crested Gecko Care
1. How often should I mist my crested gecko's tank?
Mist once daily in the evening to achieve 80% humidity at night. In dry climates, you may need a second misting in the morning. Always check with a digital hygrometer to ensure humidity drops to 50–70% during the day.
2. Can I keep two crested geckos together?
No, crested geckos are solitary and territorial. Keeping two in the same enclosure leads to stress, fighting, and injury. Only house one gecko per tank. Breeding pairs can be housed together temporarily but require careful supervision.
3. What is the lifespan of a crested gecko?
With proper care, crested geckos live 15–20 years in captivity. Some individuals have reached 25 years. Consistent temperature, humidity, and diet are the keys to a long, healthy life.
4. Do crested geckos need a heat lamp?
Only if your room temperature drops below 72°F. Use a low-wattage ceramic heat emitter or side-mounted heat pad with a thermostat. Never use bright heat lamps, as they disrupt the gecko's day/night cycle and can overheat the enclosure.
5. What size tank does a baby crested gecko need?
Baby crested geckos can start in a 10-gallon tank (12 x 12 x 18 inches) to make it easier to find food and monitor health. Move to a 20-gallon tall tank when the gecko reaches 15–20 grams, usually around 6–8 months of age.
