Crested Gecko Husbandry Guide

Practical, species-specific care for crested geckos: bioactive enclosures, why heat lamps aren’t necessary, balanced CGD-first diet with insect supplementation, and steps to prevent tail drop.

Introduction

Crested geckos (Correlophus ciliatus) are arboreal, nocturnal lizards native to New Caledonia. Their ease of care and varied colors make them popular as first-time reptile pets — but they do have specific needs (vertical space, humidity cycles, and a diet that centers on prepared Crested Gecko Diets). This guide gives practical, step-by-step husbandry tailored to crested geckos, including a bioactive enclosure walkthrough, clear temperature guidance that avoids unnecessary heat lamps, a CGD-first feeding program with insect supplementation, and evidence-based tips to reduce the risk of tail autotomy.

Breed-specific considerations

• Arboreal behavior: crested geckos climb and sleep above ground; enclosures must be taller than they are wide.
• Nocturnal activity: daylight conditions should mimic natural light cycles; hide opportunities during the day are essential.
• Sensitive to high heat and rapid humidity swings: they can easily become stressed or dehydrated in overheated, dry setups.
• Tail autotomy is common: the tail is easily dropped under stress or mishandling and does not fully regrow.

Enclosure basics (size, layout, and hardware)

• Minimum adult single gecko: vertical enclosure roughly 18" x 18" x 24" (45 x 45 x 60 cm). Bigger is always better — 24" tall or taller improves welfare.
• Juveniles: small vertically oriented enclosure (12" x 12" x 18") until about 6–8 months.
• Doors: front-opening glass terrariums or screen-front wooden vivaria with secure latches.
• Lighting: low-level ambient lighting for humans; crested geckos are nocturnal and do not require bright daytime UVB. A low-output UVB tube (2.0–5.0, 10–12 hour cycle) is optional and can be beneficial but avoid direct, strong basking lamps.
• Heating: in typical indoor temperatures (72–78°F / 22–26°C) no supplemental heat is necessary. Avoid heat lamps which create hot basking spots and dry the microclimate. Use thermostat-regulated heat mats or gentle ambient room heating only if your home drops below ~68°F (20°C) consistently.

Bioactive enclosure: step-by-step setup

Creating a living (bioactive) enclosure improves humidity stability, reduces cleaning, and offers natural foraging and hiding opportunities.

Maintenance schedule for bioactive setups

• Daily: quick check (temperature, humidity, water bowl level), spot-remove visible feces.
• Nightly: mist once or twice to reach daytime humidity targets (see below). Mist more sparingly if relying on an automated fogger.
• Weekly: check plant health, clean water bowl, and remove uneaten insects and decaying food.
• Monthly: inspect substrate depth and cleanup crew population; top up substrate if necessary; wipe down glass and clean decorations if biofilm develops.

Temperature and humidity (no heat lamp needed)

• Ideal daytime temperature: 72–78°F (22–26°C).
• Nighttime temperature: 65–72°F (18–22°C) — a gentle drop at night is normal and beneficial.
• Avoid sustained temperatures above 82°F (28°C); temps above 86°F (30°C) are dangerous.
• Humidity targets: 50–70% daytime average with short, higher spikes (75–90%) at night after a misting. Crested geckos appreciate a nightly mist to rehydrate and facilitate shedding.

• If room temperature stays within the recommended range, no supplemental heat is required.
• If your house gets colder (<68°F / 20°C), use a small, thermostat-controlled under-tank heater (placed on the side of the tank, not directly under the substrate) or a low-wattage ceramic heat emitter on a thermostat at low settings. Never use bare incandescent bulbs or heat rocks.

Diet: CGD vs insects (practical feeding plan)

Crested Gecko Diets (CGD) are formulated complete diets (powdered fruit/gel mixes) designed to meet the majority of nutrient needs. Insects are a valuable protein and enrichment supplement, not the core staple for most adults.

General feeding schedule

• Juveniles (0–6 months): CGD daily. Offer insects (gut-loaded, dusted) 2–3 times/week to support growth.
• Subadults (6–12 months): CGD every 24–48 hours. Insects 1–2 times/week.
• Adults (>12 months): CGD every 48–72 hours (many owners feed 3 times/week). Insects once weekly or every other week — increase to twice weekly for breeding females or animals needing weight gain.

• Mix CGD per manufacturer directions (usually a paste consistency). Spoon a golf-ball sized amount onto a feeding cup or platform for an adult; juveniles get smaller portions scaled to body size.
• Insects: choose gut-loaded crickets or dubia roaches; feed only appropriately sized prey (no wider than the gecko’s head). Dust insects with calcium powder (without D3) at every insect feeding; add a multivitamin with D3 once every 1–2 weeks unless your CGD already lists adequate D3/calcium.

• CGD supplies balanced carbohydrates, vitamins, and minerals and reduces the risk of calcium deficiency and metabolic bone disease compared to insect-only diets.
• Solely feeding insects can cause calcium/phosphorus imbalances if dusting isn’t rigorous and timed correctly.

• Feeding wild-caught insects (parasites/toxins risk).
• Relying solely on insects or raw fruit — both can lead to nutritional deficiencies.
• Overfeeding CGD or leaving wet food in the enclosure (mold risk).

Handling and tail-drop prevention

Tail autotomy (tail drop) is a common defense reaction. It’s permanent (tails do not fully regrow) and can be traumatic for the gecko.

Handling best practices

• Never pick up by the tail. Approach from the side and allow the gecko to climb onto your hand.
• Support the body and feet — let them sit on your palm rather than grabbing.
• Keep sessions short (5–10 minutes) and infrequent for young or stressed geckos (2–3 times per week maximum).
• Avoid handling during shedding, immediately after feeding, or when gravid.
• Reduce stressors: loud noises, sudden movements, and lighting changes can provoke tail loss.

• Remove sharp, abrasive décor where tail could snag.
• Use soft, natural branches and plenty of foliage so they feel secure.
• Keep tank mates out: crested geckos are best housed singly or in carefully managed pairs; cohabitation increases the risk of nips and tail damage.

• If bleeding: apply light pressure with sterile gauze and seek veterinary care.
• If clean and only skin missing: keep the animal warm, quiet, and monitored for infection; consult an exotic vet for wound care and antibiotics if infection or persistent bleeding occurs.

Common mistakes owners make

• Using heat lamps that overheat and dry the enclosure.
• Feeding insects as the staple instead of CGD, increasing MBD risk.
• Over-misting or under-misting; both can cause respiratory or shedding problems.
• Housing juveniles in very large open-floor tanks (they climb and need vertical space and cover).
• Using loose calcium sand or small particulate substrate that could cause impaction in the rare event of accidental ingestion.

Signs of problems — when to see a veterinarian

Seek veterinary attention (exotic/reptile-experienced veterinarian) if you see any of the following:

• Refusal to eat for more than 5–7 days in an adult (sooner for juveniles).
• Rapid weight loss or visible bony spine/hips.
• Swollen or bent limbs, soft jaw, or other signs of metabolic bone disease.
• Chronic diarrhea, bloody stools, or bright-red cloacal discharge.
• Open wounds, continuing bleeding after tail loss, or signs of infection (pus, smell, swelling).
• Difficulty shedding (retained shed on toes/eyes) for more than a day despite appropriate humidity.
• Respiration changes: bubbling, wheezing, open-mouth breathing, lethargy.

Product recommendations (categories)

• Enclosure: tall glass terrarium or wooden vivarium with front access.
• Substrate: bioactive soil mix (coco coir/orchid bark/topsoil) or high-quality coconut fiber for non-bioactive setups.
• Drainage: LECA/expanded clay and mesh separator.
• Cleanup crew: springtails and isopods for bioactive systems.
• Furnishings: cork bark, natural vines, live/plastic plants, feeding platforms.
• Monitoring: digital hygrometer/thermometer (with probe), and a thermostat for any supplemental heat.
• Feeding: small ceramic feeding dishes, commercial Crested Gecko Diet (CGD), gut-loaded feeder insects, calcium and multivitamin powders.
• Cleaning: reptile-safe disinfectant, sterile gauze for emergency wound care.

Key takeaways

• Crested geckos are arboreal and thrive in vertical, humid enclosures with plenty of foliage and hides.
• In most homes, no heat lamp is needed — keep temperatures 72–78°F with nighttime drops to the mid-60s.
• Make a high-quality Crested Gecko Diet the staple; supplement with gut-loaded, dusted insects on a schedule based on age and breeding status.
• Bioactive setups stabilize humidity and reduce maintenance when established correctly; follow a step-by-step setup and allow a cycling period before introducing your gecko.
• Prevent tail drop by gentle handling, removing hazards in the enclosure, and minimizing stress. If tail autotomy occurs with bleeding or signs of infection, seek an exotic veterinarian promptly.
