Crested Gecko Care Guide: Temperature, Humidity, Diet & More
Complete care guide for crested geckos including temperature gradients, humidity levels, feeding schedule, handling tips, and common health issues.
Crested geckos are native to the humid forests of New Caledonia, where temperatures range from 75°F (24°C) at night to 85°F (29°C) during the day. To replicate this gradient in your enclosure, maintain a temperature range of 78-82°F (25-28°C), with a basking spot around 84°F (29°C). Use low-wattage heat sources like ceramic heat emitters or heat mats specifically designed for reptiles.
Humidity is crucial for crested geckos. Maintain a consistent humidity level of 60-80% by misting the enclosure daily and using a humid hide. Avoid over-misting, which can lead to respiratory issues. The ideal humidity gradient mimics their natural environment — higher near water features or plants, slightly lower in drier areas.
Crested geckos are primarily insectivores but can thrive on specialized commercial diets. Feed them a high-quality crested gecko food mix 2-3 times per week, supplementing with fresh fruits like berries, melons, and apples (cut into small pieces to prevent choking). Avoid citrus fruits and those high in sugar. Fresh water should always be available — change it daily to prevent bacterial growth.
Prey items for crested geckos should include pinhead crickets, small fruit flies, and tiny waxworms (used sparingly as treats). Never feed live prey, as this can cause stress and injury. Frozen-thawed insects are safer and more nutritious. Feed according to your gecko's size — juvenile geckos need more frequent, smaller meals than adults.
Crested geckos are generally docile but may nip if frightened or during breeding season. Handle them gently, supporting their body and tail (since they can't regrow tails). Start with short sessions of 10-15 minutes, gradually increasing time as your pet becomes more comfortable. Never pick up a gecko by its legs.
Common health issues in crested geckos include metabolic bone disease from inadequate calcium and vitamin D3 supplementation. Monitor for signs like softening bones, swollen joints, or lethargy. Regular veterinary check-ups are crucial to prevent these conditions. Also watch for respiratory infections — sudden changes in appetite, color change, or labored breathing require immediate attention.
For optimal health, provide a spacious enclosure with vertical space that allows your crested gecko to climb and exercise naturally. A minimum tank size of 12 inches tall by 18-24 inches wide is recommended. The taller the better — these arboreal geckos love to roam and hide in foliage.
Maintain pristine environment cleanliness. Clean food and water dishes daily, and replace substrate completely every 2-3 months. Avoid using loose substrates like sand or wood shavings that can cause respiratory problems; instead opt for reptile carpet, paper towels, or indoor/outdoor carpeting.
