The Complete Guide to Crested Gecko Care: Morphs, Health & What Every Owner Must Know
Crested geckos are, in my honest opinion, one of the most rewarding reptiles you can keep — and I say that as someone who has maintained everything from ball pythons to tarantulas on my homestead. They are handleable, hardy within their temperature sweet spot, eat a commercially prepared diet that takes the guesswork out of nutrition, and come in a dizzying array of colors and patterns called morphs. Whether you are brand new to reptiles or adding a crestie to an existing collection, a solid crested gecko care guide will save you expensive mistakes and help you give your animal a full, healthy 15-to-20-year life.

Species Overview: What Is a Crested Gecko / Eyelash Gecko? {#species-overview}
The crested gecko — Correlophus ciliatus, formerly classified as Rhacodactylus ciliatus — is a semi-arboreal gecko native to the southern parts of New Caledonia, a French island territory in the southwest Pacific. It was considered extinct for most of the 20th century. Scientists rediscovered it in 1994 after Cyclone Kuma, and within a decade it had become one of the most popular captive reptiles in the world. That backstory alone tells you something about the animal: it is resilient.
The common name “eyelash gecko” comes from the row of small, hair-like projections that run above each eye and along the body from head to tail. These are not actual eyelashes — they are skin extensions called paravertebral crests — but they give the animal a distinctly expressive, almost cartoon-like face. Eyelash gecko care and crested gecko care are exactly the same thing. The two names refer to the same species (Correlophus ciliatus), and you will see both used interchangeably in the hobby. For clarity throughout this guide, I will use “crested gecko” as the primary name and note “eyelash gecko” where relevant for search purposes.
Taxonomy at a Glance
- Family: Diplodactylidae
- Genus: Correlophus (split from Rhacodactylus in 2012)
- Species: C. ciliatus
- Common names: Crested gecko, eyelash gecko, New Caledonian crested gecko
- Native range: Grande Terre and Isle of Pines, New Caledonia
- Wild habitat: Humid rainforest understory; arboreal/nocturnal lifestyle
Key Physical Traits
Crested geckos have several distinctive features that make them easy to recognize and, frankly, fascinating to keep. Their prehensile tails (when intact) and sticky lamellae on their toe pads allow them to climb virtually any surface — glass, plastic, wood — without issue. Unlike many geckos, they have no movable eyelids; they lick their eyes to keep them clean, which is one of their most endearing behaviors.
One fact every new keeper needs to internalize early: crested geckos can drop their tails (autotomy) as a defense mechanism, and unlike many other lizards, they do not regrow them. A crested gecko without its tail is called a “frogbutt” in the hobby and lives a completely normal, healthy life — but if tail-intact specimens are important to you for display or breeding programs, you need to handle with care and manage stress proactively.
Crested Gecko as a Pet: Pros, Cons, and Who They’re Best For {#crested-gecko-as-pet}
I get asked about the crested gecko as a pet constantly, especially by people who are keeping reptiles for the first time. Here is my honest assessment after years on the homestead with a mixed collection.
Why Crested Geckos Make Excellent Pets
1. No strict UVB requirement (though it is beneficial). Many reptiles — bearded dragons, chameleons, tortoises — have rigid UVB lighting needs. Crested geckos synthesize D3 adequately from a calcium+D3-supplemented diet. You will not kill one by omitting UVB, provided supplementation is correct. This dramatically lowers setup cost and complexity for beginners.
2. Commercial diet eliminates guesswork. Prepared crested gecko diet (CGD) from brands like Pangea and Repashy covers nutritional needs as a staple. There is no need to balance calcium-to-phosphorus ratios from scratch, gut-load multiple insect species, or second-guess vitamin A sources. This is genuinely unusual in the reptile hobby — most species require more complex feeding regimens.
3. Handleable and calm. With patient, consistent handling sessions that respect the animal’s pace, most crested geckos become tolerant to regular handling. They rarely bite (and when they do, it barely registers on human skin). Their habit of jumping from hand to hand during sessions is more endearing than alarming once you expect it.
4. Extraordinary morph diversity. From moonglow (patternless cream) to extreme harlequin (deep red-orange with bold cream patterning), the visual variety in this species rivals ball pythons and leopard geckos. Collecting morphs becomes a hobby within a hobby for many keepers.
5. Long lifespan means a long relationship. 15–20 years with proper care. This is both a pro and a consideration — you are making a long-term commitment.
6. Quiet and space-efficient. No vocalizations (unlike some gecko species), no elaborate custom enclosures needed, no massive footprint. A single adult lives comfortably in an 18×18×24 enclosure.
Where Crested Geckos Require Attention
1. Nocturnal activity pattern. Your crestie will be most active in the evening and overnight. If you want an animal you can watch during the day, a bearded dragon or blue-tongue skink may be a better fit. Crested geckos spend most daylight hours sleeping in foliage.
2. Heat sensitivity. Temperatures above 82°F (28°C) cause heat stress. Above 85°F, they can die. If you live somewhere that gets genuinely hot summers without reliable air conditioning, this is a serious management challenge. On my homestead I use a dedicated reptile room with a window unit — this is not optional in warmer climates.
3. Permanent tail loss. One stressful drop and the tail is gone for life. For breeding programs tracking morph genetics, this matters.
4. Nocturnal feeding observation challenges. Because they eat at night, monitoring actual food consumption requires some creativity — leave food in the evening and check in the morning.
Who is this species best for? Anyone from a 10-year-old child (with parental supervision) to an experienced herpetologist. They are genuinely one of the best first reptiles available, and they remain interesting enough for expert keepers who get into morphs and breeding. If you want a deeper dive into the morph side of this species, I cover the Ultimate Crested Gecko Morph Guide in a full review — it is specifically aimed at keepers who want to move beyond basic care into genetics.
Crested Gecko Care Guide: Enclosure Setup {#enclosure-setup}
Getting the enclosure right is the foundation of everything else. Crested geckos are arboreal — they climb and prefer height over floor space. This is the most important spatial concept in crested gecko care.
Tank Size by Age and Weight {#tank-size}
| Life Stage | Weight Range | Minimum Enclosure |
|---|---|---|
| Hatchling / Juvenile | < 10g | 12” × 12” × 18” (Exo Terra small tall) |
| Sub-adult | 10–25g | 12” × 12” × 18” to 18” × 18” × 18” |
| Adult | 35g+ | 18” × 18” × 24” (minimum) |
| Adult pair / breeding | 35g+ (both) | 18” × 18” × 36” or larger |
The 18×18×24 (approximately 20 gallon tall equivalent) is the widely accepted adult minimum, and I would call it a true minimum rather than a comfortable recommendation. If budget and space allow, an 18×18×36 or a custom PVC enclosure gives adults more vertical territory and makes bioactive setups far more successful.
For detailed breakdown of tank dimensions, enclosure brands, and how humidity interacts with tank volume, see my dedicated crested gecko tank size and humidity guide.
Key principle: wider is not better for cresties. They go up. A 40-gallon breeder (horizontal orientation) is inferior to a 20-gallon tall for an arboreal species.
Substrate Options {#substrate}
Your substrate choice affects humidity management, aesthetics, and whether a bioactive setup is feasible.
Coconut fiber / coco coir: The most widely used substrate. Holds humidity well, available everywhere, inexpensive. Alone it tends to compact; mixing with orchid bark improves texture. Not ideal for bioactive long-term.
ABG mix (Atlanta Botanical Garden mix): The standard for bioactive planted vivariums. Typically composed of orchid bark, tree fern fiber, long-fiber sphagnum moss, and horticultural charcoal. Excellent drainage layer + bioactive substrate = near self-maintaining humidity cycle. More upfront cost and effort, but dramatically reduces maintenance labor long-term.
Eco Earth + orchid bark blend (DIY): A common keeper-made substrate: 60% Eco Earth, 30% orchid bark, 10% sphagnum moss. Functional and much cheaper than commercial bioactive mixes.
Paper towel (quarantine/temporary): For new arrivals, sick animals, or hatchlings during initial monitoring periods. Allows easy observation of waste and any parasites. Never use long-term.
What to avoid: Sand, gravel, calcium sand, repti-carpet, and any loose substrate that forms compactible chunks hatchlings might ingest accidentally.
Furnishing and Climbing Structures {#furnishing}
A crested gecko enclosure without adequate climbing structure is functionally useless — you are housing an arboreal animal in a vertical space and not giving it anything to climb. Aim for:
- Cork bark flats and tubes: The closest thing to natural habitat. Lightweight, holds humidity well, provides both climbing surface and hide spots. Cork rounds make excellent sleeping hides at mid-to-upper enclosure height (where cresties naturally rest during the day).
- Pothos (Epipremnum aureum): The workhorse plant of the crestie enclosure. Nontoxic, thrives in the humidity/light conditions of a typical crested gecko setup, grows aggressively enough to fill in gaps and provide real cover.
- Fake vines and foliage: Commercial reptile vines (Exo Terra, Zoo Med) work well for structure. Supplement with real plants where possible for humidity buffering and enrichment.
- Horizontal branches: At varying heights. Crested geckos spend significant time on horizontal perches — do not make everything vertical.
- Water dish: Shallow (no deeper than the gecko’s snout when standing flat). Placed at lower enclosure level. Misting replaces most drinking needs, but a standing dish is important backup.
- Food ledge or magnetic ledge: For CGD cups. Placed at mid-to-upper height to reflect natural arboreal foraging behavior.
Avoid overcrowding — the enclosure should be full of cover but not so cluttered that air cannot circulate. Poor airflow is a respiratory infection vector.
Temperature and Heating {#temperature}
This is where crested gecko care diverges sharply from most other popular reptiles, and it is the detail that catches the most new keepers off guard.
Crested geckos do not thermoregulate via basking the way bearded dragons or blue-tongue skinks do. They come from a temperate island climate, not a tropical basking environment. They want a stable, cool ambient temperature — not a hot spot at one end and a cool zone at the other.
Temperature Parameters
| Zone | Target |
|---|---|
| Ambient (day) | 72–78°F (22–26°C) |
| Ambient (night) | 65–72°F (18–22°C) — natural drop is fine |
| Upper danger limit | 82°F (28°C) |
| Critical danger | 85°F+ (29°C+) — heat stress / death risk |
| Lower tolerance | 65°F (18°C) for short periods |
In most temperature-controlled homes in North America and Europe, no supplemental heating is needed. The animal is comfortable at typical household ambient temperatures year-round.
When You Need Supplemental Heating
- Ambient room temperature regularly drops below 68°F (20°C) in winter
- You live in a very cold climate with drafty enclosure placement
- Night drops are extreme (below 62°F consistently)
Appropriate heating tools:
- Ceramic heat emitter (CHE): Produces heat without light — appropriate for maintaining night temperature without disrupting photoperiod. Placed on top of a mesh enclosure lid with a thermostat (non-negotiable — never run a CHE without a thermostat).
- Radiant heat panel (RHP): Mounted inside the lid of PVC enclosures. More even heat distribution, less drying effect than CHE. Preferred for bioactive setups.
- Under-tank heater (UTH): Generally not appropriate for arboreal species that spend minimal time on the substrate.
What you must never use:
- Hot rocks / heat rocks: Create localized contact burns. No.
- Incandescent basking bulbs: Create the hot-cool gradient this species does not want or need, and can spike temperatures dangerously.
Use a digital thermometer (probe or infrared gun) to verify temperatures — do not trust the ambient room thermostat to tell you what is happening inside a glass enclosure near a heating element.
Crested Gecko Humidity: Parameters and Daily Management {#humidity}
Humidity management is the other technical pillar of good crested gecko care, and it trips up more keepers than temperature does.
Target Parameters
- Daytime humidity: Allow to drop to 50–60% (the “dry” phase)
- Evening/night humidity: 70–80% after misting (the “wet” phase)
- Overall range: 60–80% is the commonly cited target; the important thing is the daily cycle, not a static reading
Crested geckos evolved in a habitat with distinct wet and dry periods throughout the day. Mimicking this cycle in captivity serves two purposes: it triggers normal drinking behavior (they drink water droplets from leaves and enclosure walls after misting) and it prevents the chronic high humidity that causes bacterial and fungal respiratory issues.
Daily Misting Protocol
Evening misting: Thoroughly mist the enclosure interior — walls, plants, substrate surface — until water droplets are visible and the humidity rises to 75–80%. This is also when you should offer fresh food, since the gecko will become active shortly after.
Let it dry: During the day, the enclosure humidity naturally drops through evaporation and ventilation. The goal is for it to reach 50–60% before the next evening misting. If it never dries below 70%, you have an airflow problem.
Automated misting systems: Ultrasonic foggers or pressure misters on timers eliminate the manual misting step. If you have multiple enclosures or travel frequently, an automated system is worth every cent. Be careful with foggers — they can raise humidity to the point where airflow cannot compensate, particularly in glass enclosures with only top ventilation.
Monitoring
A digital hygrometer with a probe is essential — not optional. Analog hygrometers are notoriously inaccurate. Spend $15 on a digital unit (Govee, Inkbird, AcuRite) and place the probe at mid-enclosure height.
Enclosure choice affects humidity management significantly. All-glass enclosures with only top ventilation retain humidity well but can become stagnant. Exo Terra-style front-vented glass terrariums balance humidity retention with airflow. PVC enclosures are excellent for humidity regulation and insulation. Screen/mesh enclosures shed humidity too quickly in dry climates and are generally unsuitable.
Lighting: UVB, Photoperiod, and Planted Vivarium Options {#lighting}
Crested geckos are often described as not needing UVB, and while that is technically true in the sense that they will not die without it (provided D3 supplementation is adequate), the science increasingly supports UVB as genuinely beneficial.
The UVB Situation
Research on wild-caught crested gecko behavior shows that individuals do occasionally bask in dappled sunlight in the wild — they are not exclusively shade-dwellers. Studies and keeper reports both indicate that access to low-intensity UVB (5.0 UVI or a T5 HO 6% bulb at appropriate distance) improves appetite, activity, color expression, and long-term skeletal health.
My recommendation: provide low-intensity UVB. It adds a small amount of cost and complexity for a genuine benefit, especially for long-lived animals with 15-to-20-year time horizons. You are not just keeping a crested gecko through your teenage years — you may be keeping it through your twenties and into your thirties.
UVB Setup Parameters
- Bulb type: T5 HO 6% (Arcadia Forest 6%, Zoo Med ReptiSun 5.0) or equivalent
- Placement distance: Follow the manufacturer’s Ferguson zone chart for your specific bulb; typically 15–20 inches from the animal’s resting height for a 6% T5
- Photoperiod: 12 hours on / 12 hours off year-round (consistent photoperiod matters; erratic day length can trigger breeding behaviors in females at inappropriate times)
- Cover density: If using live plants that create heavy shade, position a UVB gradient so the gecko can choose its exposure
For Planted / Bioactive Vivariums
If you build a planted bioactive vivarium (which I strongly encourage for the humidity-buffering and enrichment benefits), standard plant grow lights in the 5,000–6,500K color temperature range work well. Pair with a low-intensity UVB strip at appropriate distance. The plants will thrive, the gecko will have naturalistic light, and your enclosure will become a living system rather than a sterile box.
Do not use high-output plant lights designed for densely planted aquariums — these can raise enclosure temperature significantly and create light levels far exceeding what a forest-understory reptile needs.
Feeding and Nutrition {#feeding}
The feeding side of crested gecko care is one of its biggest advantages over other reptile species. You do not need to master complex gut-loading protocols, balance multiple food items from scratch, or worry about vitamin A toxicity from live prey variety. A well-formulated CGD handles most of it.
Commercial Crested Gecko Diet (CGD) {#cgd}
The two dominant brands are Pangea and Repashy, both formulated specifically for Correlophus ciliatus and widely used in professional breeding operations.
Pangea offers multiple formulas targeting different life stages and breeding status (Fig & Insects, Breeding Formula, Watermelon). Their Breeding Formula is nutritionally dense and appropriate as a year-round staple for adults, not just breeding animals.
Repashy Crested Gecko MRP (Meal Replacement Powder) is the original commercial CGD, developed in the early 2000s. It remains a solid staple and is often slightly less expensive than Pangea formulas.
Both brands are mixed with water (typically 1 part powder to 2 parts water by weight) and served in small cups or ledges. Refrigerate mixed CGD and discard after 24 hours in the enclosure (sooner in warm conditions).
Rotation: Many experienced keepers rotate between two or three CGD formulas rather than committing to one brand exclusively. This prevents nutritional gaps if one formula has a weak point and keeps feeding interesting for the animal.
Live Insects {#insects}
Insects are not strictly required when quality CGD is fed, but they provide protein, enrichment, and natural feeding behavior stimulation. Feed live insects 1–2 times per week for adults, 2–3 times per week for juveniles and breeding females.
Best options:
- Dubia roaches: Excellent nutrition, low odor, cannot climb smooth surfaces or fly. The gold standard feeder insect for crested geckos.
- Black soldier fly larvae (BSFL / Nutrigrubs / Calciworms): High in calcium, no gut-loading required. Good for calcium supplementation.
- Crickets: Widely available, accepted readily, but require gut-loading and have a short shelf life. Chirping noise is a real consideration for bedroom enclosures.
- Mealworms: Occasional treat only — high in fat, low calcium:phosphorus ratio. Not a staple.
Size rule: Feeders should be no larger than the space between the gecko’s eyes. Oversized prey causes regurgitation and stress.
Gut-loading: Feed live insects a nutritious diet for 24–48 hours before offering them to your gecko. Commercial gut-load diets (Repashy Bug Burger, Timberline Cricket Diet) are convenient. Fresh vegetables (collard greens, butternut squash, carrots) work equally well.
Supplementation {#supplementation}
Even with quality CGD that includes calcium and D3, light supplementation on insect feeders adds an insurance layer.
- Calcium + D3 powder: Dust insects lightly at every insect feeding. Do not over-supplement — excessive D3 causes hypercalcemia, which damages kidneys.
- Plain calcium (no D3): Some keepers leave a small dish of plain calcium in the enclosure for the gecko to self-regulate. This is safe; they will not over-consume calcium without D3.
- Vitamin supplement (Repashy Supervite, Arcadia EarthPro-A): Once every 2 weeks on insects. Not needed if CGD is the primary staple.
Water: Always provide fresh water in a shallow dish, and mist the enclosure nightly. Crested geckos drink primarily from droplets on surfaces but will use a standing dish as backup. Change the dish water daily.
Handling and Temperament {#handling}
Most crested geckos, with consistent and patient handling from a young age, become tolerant companions. They will not seek out human interaction the way a dog does, but they accept it with minimal stress once acclimated.
Building Trust
- Start slow: With a new gecko, limit handling to 5–10 minutes every few days for the first 2–4 weeks. Let the animal adjust to its new environment before adding handling stress on top.
- Hand-walking technique: Rather than gripping the gecko, let it walk from hand to hand. Cup your hands together and allow it to move freely between them. This keeps the animal moving, which is natural, and eliminates the restraint that triggers defensive behavior.
- Read body language: A gecko that flattens its body, gapes its mouth, or makes chirping/squeaking sounds is stressed. Return it to the enclosure and try again another day. A gecko that moves slowly and flicks its tongue occasionally is calm and curious.
- Avoid handling during shed: A gecko in shed (look for dull, grayish skin and eyes) is irritable and delicate. Leave it alone until the shed completes.
Tail Drop Prevention
Tail autotomy (deliberate tail drop) is a stress response. The tail does not regenerate. Prevention strategies:
- Never restrain by the tail
- Avoid sudden movements or grabs from above (mimics aerial predator attack)
- Do not allow the gecko to see its own reflection repeatedly (can trigger territorial stress in some individuals)
- Keep handling sessions short when the animal is new or showing stress signals
- Supervise children carefully during handling
A gecko that has dropped its tail is called a “frogbutt” in the hobby. It lives a completely normal, healthy life — but if intact tails matter to you for display or future breeding value, handling discipline is important.
Shedding (Ecdysis): What’s Normal, What’s Not {#shedding}
Crested geckos shed their entire skin periodically — more frequently in juveniles (every 2–3 weeks) and less frequently in adults (every 4–8 weeks). Unlike some reptiles, crested geckos typically eat their shed skin immediately after, which makes it easy to miss that a shed occurred at all.
What Normal Shedding Looks Like
- Skin becomes dull and grayish 1–2 days before shed
- Eyes appear cloudy/bluish (called “in the blue”)
- Gecko may be less active and eat less during this period
- Shed typically completes within a few hours overnight
- Animal usually eats shed immediately after
Do not disturb a gecko in shed and do not try to help remove the skin unless there is a clear problem.
Retained Shed (Dysecdysis)
Retained shed is the most common shedding issue. It occurs when humidity is too low and the skin does not release cleanly. Warning signs:
- Retained shed on toes (will constrict circulation — check toes after every shed)
- Retained eye caps (shed around the eye that hasn’t released)
- Patches of old skin remaining after 24–48 hours post-shed
Treatment for retained shed:
- Increase humidity to 80%+ for 24 hours
- Offer a warm, damp hide — a small container with moistened paper towels inside
- For retained toe shed: gently soak the affected foot in warm water for 5–10 minutes, then roll the retained skin off with a moist cotton swab. Never pull forcefully.
- For retained eye caps: consult a reptile veterinarian. Forceful removal of eye caps risks corneal damage.
The best treatment is prevention: maintain consistent humidity cycles and a moist hide (a small container with a lid and damp sphagnum inside) year-round.
Common Health Issues and Prevention {#health}
Crested geckos are robust animals when kept correctly. The health issues that do arise are almost always husbandry-related — meaning they are preventable.
Metabolic Bone Disease (MBD)
What it is: Calcium/phosphorus imbalance, vitamin D3 deficiency, or both, causing progressive demineralization of the skeletal system. Classic signs include soft or rubbery jaw, bent limbs, inability to climb, and seizures in severe cases.
Cause in crested geckos: Feeding primarily insects without D3 dusting, or offering a diet lacking adequate calcium over extended periods. Very rare in animals kept on quality CGD as a staple.
Prevention: Use quality CGD as the primary diet, dust insects with calcium+D3 at every insect feeding, and consider low-intensity UVB to support endogenous D3 synthesis.
Prognosis: Caught early, MBD is reversible with dietary correction. Advanced cases involve permanent skeletal deformity and significantly shortened lifespan. Veterinary calcium injections are sometimes needed for severe cases.
Respiratory Infections
What it is: Bacterial or viral infection of the respiratory tract. Signs include open-mouth breathing, audible wheezing or clicking, mucus around nostrils, and lethargy.
Cause: Almost always chronic high humidity without adequate airflow. A consistently wet enclosure at 85%+ humidity with poor ventilation becomes a bacterial growth medium.
Prevention: Maintain the wet/dry humidity cycle. Ensure adequate enclosure ventilation. Do not let foggers run continuously.
Treatment: Requires veterinary care — oral or injectable antibiotics depending on pathogen. Do not attempt to treat respiratory infections with over-the-counter products.
Floppy Tail Syndrome (FTS)
What it is: A condition where the tail bends laterally or dorsally at the base, appearing floppy or deformed. More common in heavier animals.
Cause: Contested. The primary hypothesis is that geckos that habitually sleep vertically or upside-down on enclosure walls allow their body weight to torque the tail connection over time. A genetic predisposition is also suspected by many breeders.
Management:
- Add more horizontal perches and cork hides at multiple heights so the gecko has better resting options than the glass wall
- Avoid breeding FTS-affected individuals into programs where tail conformation matters
- Mild FTS does not appear to cause pain or significantly reduce quality of life
Parasites
Internal parasites (pinworms, coccidia, cryptosporidium) are common in wild-caught animals but uncommon in captive-bred specimens from reputable breeders. Signs include weight loss despite normal feeding, bloating, loose or bloody stools, and lethargy.
A fecal examination by a reptile-experienced veterinarian is the correct diagnostic step — do not self-medicate with parasite treatments, as dosing errors are dangerous.
Buy captive-bred: The single best prevention against parasites is purchasing only captive-bred crested geckos from established breeders. Wild-caught specimens carry parasite loads and stress burdens that can take months to address.
Egg Binding (Dystocia) in Females
Female crested geckos — even those kept without males — will produce infertile eggs. Gravid females (carrying eggs) will be visibly enlarged and may refuse food. Egg binding occurs when eggs cannot be laid, often due to inadequate laying substrate, calcium deficiency, or dehydration.
Provide a deep, moist substrate section or a dedicated egg-laying box (a container with moist eco earth at 3+ inches depth) year-round for any adult female.
Understanding Crested Gecko Morphs {#morphs}
Morph diversity is one of the biggest draws to this species, and understanding morphs requires a working knowledge of both visual classification and basic genetics. This section introduces the major categories — for full depth on morph genetics, identification, and how to select morphs for breeding programs, see my review of the Ultimate Crested Gecko Morph Guide.
Major Pattern Morphs
Flame: A dorsal stripe of contrasting color (often cream, yellow, or orange) running down a darker base color. One of the most common and earliest-recognized morphs.
Harlequin: Lateral patterning in addition to the dorsal stripe — patches of cream or yellow extending down the sides. Harlequin percentage describes how much of the side is covered. Higher coverage (extreme harlequin) commands premium pricing.
Pinstripe: Raised dorsal scales that form a continuous cream or white stripe along the back, often with pinstripe extensions along the tail. A structural morph — the stripe is tactile, not just visual.
Dalmatian: Random spots of dark pigment on any base morph. Spot count varies from a few (25-spot dalmatian) to hundreds (super dalmatian). Dalmatian patterning can appear on flames, harlequins, or pinstripes.
Phantom: A ghost-like, low-contrast version of the harlequin pattern. Base and pattern elements have minimal contrast, creating a muted, washed appearance.
Brindle: Irregular, broken dorsal patterning rather than the clean flame stripe. Organic and varied in expression.
Moonglow: Patternless, pale cream to white with no visible markings. One of the most visually striking morphs for its simplicity.
Tricolor: Three distinct color zones in the pattern, often combining deep base color, an intermediate tone, and bright cream patterning.
Color and Structural Traits
Beyond pattern, crested geckos are evaluated on base color (ranging from dark chocolate through red, orange, yellow, and cream), pattern color intensity, structural element quality (clean pinstripes, crest conformation, tail base), and fired-up vs. fired-down expression — because crested geckos can dramatically shift their color intensity based on temperature, mood, and activity level.
Morph genetics in crested geckos are largely not Mendelian in the simple dominant/recessive sense that defines ball python morphs. Most traits appear polygenic and are selected through multi-generation breeding programs rather than single-pairing outcomes. This makes morph work both more nuanced and, arguably, more interesting than species with more predictable genetic maps.
If you are ready to go deeper on morphs and breeding genetics, my full review of the Ultimate Crested Gecko Morph Guide covers what the guide contains, who it is aimed at, and whether the depth justifies the investment. I also address questions about its credibility directly in my is the Ultimate Crested Gecko Morph Guide a scam or legit? piece.
Breeding Crested Geckos: An Introduction {#breeding}
Breeding crested geckos is significantly more accessible than breeding many other reptile species, which contributes to the robust hobbyist breeding market. You do not need specialized incubation equipment, costly breeding loans, or large-scale setups to produce a first clutch.
Prerequisites Before Breeding
Female weight is the non-negotiable threshold. Females must reach at minimum 35g, and most experienced breeders recommend 40g+, before introduction to a male. Breeding underweight females causes calcium deficiency, egg binding, and death. Weigh your female monthly — do not estimate.
Age: Sexual maturity is typically reached at 12–18 months for females and slightly earlier for males, but weight is a more reliable indicator than age.
Health baseline: Both animals should be parasite-free, eating well, and at proper weight before any pairing.
Breeding Season and Pairing
In their native New Caledonia, crested geckos breed in response to seasonal temperature and photoperiod changes. In captivity, a cooling period of 68–72°F for 8–12 weeks (reduced from normal 72–78°F ambient) with a slightly shortened photoperiod (10 hours light) mimics winter and triggers hormonal readiness. This is optional — many geckos breed year-round without cycling — but cycling improves fertility rates and egg production quality.
Pairing: Introduce the male to the female’s enclosure briefly and observe carefully. Some females immediately accept the male; others show aggression. Remove the male if the female is repeatedly fleeing, biting, or showing extreme stress. Unsuccessful introductions should be attempted again in 1–2 weeks.
Egg Development and Laying
After successful mating, gravid females develop 2 eggs (crested geckos consistently produce 2-egg clutches) over approximately 30 days. You can often see or feel the eggs through the abdominal wall of a very gravid female held up to light.
Laying substrate: The female needs a deep moist substrate area or a dedicated egg box (a container with 3–4 inches of moist eco earth with a small opening for entry). She will bury the eggs — without an appropriate laying site, egg binding is a genuine risk.
Incubation
Crested gecko eggs are incubated at room temperature in most cases — this is another reason the species is accessible to new breeders.
- Temperature range: 68–78°F (20–26°C)
- Optimal: 70–74°F for standard incubation
- Incubation period: 60–90 days, highly dependent on temperature (cooler = longer incubation)
- Substrate: Vermiculite or Hatchrite at appropriate moisture (vermiculite holds a slight imprint when squeezed but releases no free water)
- Container: Semi-sealed deli cups with 1–2 small ventilation holes — enough gas exchange, minimal moisture loss
Do not open eggs to check on development. Mark the top of each egg with a pencil dot (so you can orient them consistently if they need to be moved) and leave them undisturbed.
Hatchlings emerge at 3–4 inches total length and can be set up in smaller enclosures (12×12×18) with all the same parameters as adults scaled down. Offer CGD from the first week and first insects around 2–3 weeks post-hatch once the animal is settled.

Frequently Asked Questions {#faq}
Is a crested gecko a good pet?
Yes, crested geckos are excellent pets for all experience levels. They are hardy, handleable, do not require UVB as a strict obligation, eat a commercially available diet, and come in a wide variety of morphs. Their calm temperament and manageable size make them one of the best beginner reptiles available.
What is the difference between a crested gecko and an eyelash gecko?
Crested gecko and eyelash gecko are two common names for the same species: Correlophus ciliatus (formerly Rhacodactylus ciliatus). The eyelash name refers to the prominent crest of skin projections above the eyes and along the body. Eyelash gecko care is identical to crested gecko care — same animal, same requirements.
What do crested geckos eat?
Crested geckos are omnivores. In captivity, they thrive on commercial crested gecko diet (CGD) products like Pangea or Repashy, supplemented with live insects (dubia roaches, crickets) 1–2 times per week. Occasional fruit can be offered as enrichment. Always provide fresh water.
How long do crested geckos live?
With proper care, crested geckos typically live 15–20 years in captivity. Some individuals with excellent genetics and husbandry reach 20+ years. Morph selection and genetic health can influence longevity — this is one of the reasons selecting from reputable captive-bred lines matters.
Do crested geckos need a heat lamp?
Crested geckos prefer temperatures of 72–78°F and do not require a traditional heat lamp in most homes. Supplemental heating (ceramic heat emitter or radiant heat panel on a thermostat) is only needed if ambient room temperature regularly falls below 68°F or exceeds 82°F.
What is a crested gecko care guide?
A crested gecko care guide is a reference covering all aspects of keeping Correlophus ciliatus: enclosure setup, temperature and humidity parameters, diet, shedding, health indicators, and handling. For keepers interested in morphs and breeding, a morph-specific guide adds genetics and selective breeding guidance. This article is the hub resource — use the links in the Key Takeaways section to find deeper coverage on any specific topic.
How do I know which crested gecko morph I have?
Crested gecko morphs are identified by pattern (flame, harlequin, pinstripe, dalmatian), color base, and structural traits. Morph identification can be tricky with juveniles, as colors often intensify and change significantly with age — a “mystery” juvenile can turn into a stunning extreme harlequin by adulthood. A dedicated morph guide covers identification charts and genetic inheritance patterns in the detail this article cannot fit.
If morphs and breeding are where you want to go next, the Ultimate Crested Gecko Morph Guide is the most comprehensive resource I have found specifically for Correlophus ciliatus morph identification and selective breeding strategy. See my full review for a chapter-by-chapter breakdown and my honest assessment of who it is best suited for.
Key Takeaways and Internal Links {#takeaways}
A good crested gecko care guide comes back to a handful of non-negotiables: keep temperatures between 72–78°F and never above 82°F, maintain a daily wet/dry humidity cycle (not constant high humidity), feed quality CGD supplemented with dusted insects, provide adequate vertical space and climbing structure, and buy captive-bred from a reputable source.
Everything else — morphs, planted vivariums, breeding programs, advanced lighting setups — builds on that foundation. Get the fundamentals right first, then explore the depth.
