Crested geckos are popular for good reason: they stay a manageable size, do not need intense heat or UVB-heavy desert-style lighting, and usually adapt well to regular gentle maintenance. The key is not chasing perfection every hour, but keeping their enclosure in a steady, safe range over time.
Most care problems come from basics drifting too far: air that stays too dry or constantly wet, temperatures that run too hot, an enclosure with too little cover, or a diet built around treats instead of a complete crested gecko diet. A simple routine is usually better than a complicated one you cannot keep consistent.
Crested geckos do best with humidity that rises after misting and then dries down before the next misting. As a general target, many keepers aim for a peak around 70-80% after misting, with the enclosure drying back down to roughly 50-60% during part of the day. Constantly soaked conditions can encourage mold, dirty surfaces, and skin or respiratory issues.
Mist in the evening when your gecko becomes active, and adjust the amount based on your room conditions, ventilation, and substrate. A digital hygrometer is much more useful than guessing from how the glass looks. If the enclosure never dries, improve airflow or mist less. If it dries too fast, add moisture-holding substrate, live plants, or a larger water bowl, while still keeping good ventilation.
A quality complete crested gecko diet, often called CGD, should be the foundation of the diet. These powdered diets are mixed with water into a smoothie-like consistency and are designed to provide balanced nutrition when used as directed. Replace uneaten food regularly so it does not spoil, especially in warm or humid rooms.
Juveniles can be offered CGD frequently, often every day or every other day depending on appetite and growth. Adults commonly do well with CGD several times per week. Feeder insects such as appropriately sized crickets, dubia roaches, or other safe feeders can be offered occasionally for enrichment and extra protein, but they should be gut-loaded and dusted appropriately. Fruit alone is not a balanced diet and should not replace CGD.
Crested geckos are comfortable at moderate room temperatures. A general daytime range around 72-78°F is suitable for many setups, with a modest nighttime drop being fine. They can tolerate slightly cooler periods better than excessive heat, but long-term cold still affects digestion and activity.
Avoid letting the enclosure climb into the mid-80s°F or higher. Heat stress can become serious quickly in this species. If your home gets hot, cooling the room is usually safer than adding more equipment. If supplemental heat is needed in a cool room, use a thermostat-controlled heat source and make sure the gecko can move away from the warm area.
Crested geckos are arboreal, so height matters. Provide climbing branches, cork, vines, ledges, and broad leaves or hides at different levels. A bare glass box may meet size requirements on paper but still leave the animal exposed and stressed. Aim for a setup where the gecko can move through cover without sitting in the open all the time.
Useful equipment includes a digital thermometer, digital hygrometer, feeding ledge or cups, spray bottle or misting system, safe substrate, and secure ventilation. UVB is debated among keepers, but low-level UVB can be beneficial when set up correctly with shade and distance. It should not be used as a substitute for proper diet, supplementation, or temperature control.
A healthy crested gecko should have clear eyes, a steady grip, normal body condition, regular droppings, and interest in food over time. It is normal for appetite to vary with age, season, shedding, breeding condition, and enclosure changes, but ongoing weight loss or lethargy is not something to ignore.
Watch for stuck shed around toes or tail, wheezing, repeated open-mouth breathing, swelling, jaw softness, severe weight loss, runny droppings that persist, or refusal to eat for an extended period. Husbandry should be checked first, but suspected illness should be handled by a reptile-experienced veterinarian.
Many keepers mist once in the evening, with a lighter morning mist if the enclosure dries too much. The goal is a humidity spike followed by a dry-down period, not permanently wet conditions.
Yes, a quality complete crested gecko diet can be the main diet when mixed and offered correctly. Occasional gut-loaded, dusted insects can add enrichment, but fruit or insects alone are not balanced replacements.
Not always. Many do well at normal room temperatures around the low to upper 70s°F. If extra heat is needed, it should be thermostat-controlled, gentle, and arranged so the gecko can choose cooler areas.
