Crested Gecko Care Guide
The complete, research-backed guide to crested gecko husbandry. From enclosure setup to diet, handling, health, and breeding.
Introduction
Crested geckos (Correlophus ciliatus) are one of the most popular pet reptiles in the world, and for good reason. These stunning arboreal geckos are docile, hardy, and come in an incredible variety of colors and patterns. Native to the tropical forests of New Caledonia, a group of islands east of Australia, crested geckos were once thought to be extinct until they were dramatically rediscovered in 1994 during a tropical storm survey.
Since their rediscovery, crested geckos have become one of the most widely captive-bred reptile species. Their popularity stems from a unique combination of beginner-friendly care requirements, beautiful aesthetics, and engaging personalities. They are an excellent choice for first-time reptile owners and experienced keepers alike.
Why Crested Geckos Make Great Pets
- Low maintenance: No live insects required (can thrive on commercial diet alone)
- Room temperature: No special heating equipment needed in most homes
- Gentle temperament: Rarely bite, easy to handle once acclimated
- Beautiful variety: Hundreds of morph combinations available
- Long lifespan: 15-20+ years with proper care
- Quiet: Occasional soft chirps, no loud vocalizations

Enclosure Setup
Crested geckos are arboreal, meaning they spend the vast majority of their time off the ground in trees and vegetation. This makes vertical space the most important consideration when choosing an enclosure. A well-designed enclosure mimics their natural rainforest habitat with plenty of climbing surfaces, foliage, and humidity.
Enclosure Size Requirements
Baby/Juvenile (0-15g)
- 12x12x18 inches or equivalent
- Smaller space helps them find food
- Avoid large enclosures for babies
- Small Kritter Keepers work well
Adult (15g+)
- 18x18x24 inches minimum
- 24x18x36 inches ideal for one adult
- Front-opening preferred for easier access
- Screen or mesh top for ventilation
Enclosure Brand Comparisons
| Brand | Type | Pros | Cons |
|---|---|---|---|
| Exo Terra | Glass | Widely available, front opening, screen top | Heavy, screen top can dry out quickly |
| Zoo Med | Glass | Budget-friendly, decent ventilation | Doors can be tricky, limited sizes |
| Leap Habitat | PVC | Lightweight, holds humidity well, stackable | Higher price point, limited availability |
| Zen Habitats | PVC/Wood | Large sizes, great ventilation, easy assembly | Expensive, takes up more space |
| Sterilite Tubs | Plastic | Very affordable, easy to clean, stackable | Requires modification, not display-quality |
Substrate Options
- Paper towels: Best for babies and quarantine setups. Easy to clean and monitor droppings.
- Coconut fiber (eco earth): Affordable, holds humidity well. Replace every 2-3 months.
- ABG mix (bioactive): Natural blend of tree fern fiber, sphagnum peat, charcoal, and bark. Self-sustaining with a cleanup crew (springtails and isopods).
- Sphagnum moss layer: Great on top of substrate to boost humidity retention.
Avoid: Loose sand, gravel, wood shavings (cedar/pine especially), calcium sand, or any substrate that could cause impaction if accidentally ingested. Reptile carpet harbors bacteria and can snag toes.
Essential Decor & Furnishings
- Climbing branches: Cork bark tubes, driftwood, bamboo, and manzanita branches provide essential climbing surfaces
- Vines: Both live and artificial vines create pathways between branches and add visual complexity
- Plants: Pothos, bromeliads, and ficus are excellent live plant choices. Artificial plants work too but don't help with humidity.
- Hiding spots: Cork bark flats, coconut hides, and magnetic ledges at various heights give your gecko security
- Feeding ledge: A magnetic or suction cup ledge placed high in the enclosure for food cups
Bioactive Enclosure Setup
A bioactive setup creates a self-sustaining miniature ecosystem inside your enclosure. Live plants, beneficial microorganisms, and a "cleanup crew" of invertebrates work together to break down waste, maintain humidity, and reduce the need for deep cleaning. Bioactive setups are the gold standard for naturalistic crested gecko enclosures.
Substrate Layers (Bottom to Top)
Layer 1: Drainage Layer (1-2 inches)
LECA clay balls, hydroballs, or large river rock. Prevents waterlogging by allowing excess water to drain away from roots and substrate. Cover with a mesh screen barrier to keep substrate from falling through.
Layer 2: Mesh Barrier
Window screen mesh or weed barrier fabric cut to fit. Separates the drainage layer from the substrate above, preventing soil from sinking into the drainage layer over time.
Layer 3: ABG Substrate Mix (3-4 inches)
A blend of tree fern fiber, sphagnum peat moss, orchid bark, horticultural charcoal, and long-fiber sphagnum moss. This mix retains moisture, supports plant roots, and provides habitat for your cleanup crew. The Bio Dude Terra Firma and Josh's Frogs ABG Mix are popular premade options.
Layer 4: Leaf Litter & Moss Top (1 inch)
Dried magnolia, live oak, or Indian almond leaves on top create hiding spots for your cleanup crew and add natural aesthetics. A thin layer of sphagnum moss helps retain surface moisture.
Cleanup Crew
The cleanup crew is the backbone of any bioactive setup. These tiny invertebrates consume gecko waste, decaying plant matter, and mold, keeping your enclosure clean naturally.
Tropical Springtails
- Tiny (1-2mm) white or silver invertebrates
- Eat mold, fungus, and decaying organic matter
- Reproduce quickly in humid conditions
- Harmless to geckos (some geckos eat them as snacks)
- Seed a culture of 50-100 to start
Dwarf White Isopods
- Small (3-5mm) land crustaceans (roly-polies)
- Consume gecko droppings and shed skin
- Break down leaf litter into nutrients
- Dwarf white or dwarf purple species preferred
- Start with 20-30 individuals
Recommended Live Plants
| Plant | Light Needs | Benefits | Notes |
|---|---|---|---|
| Pothos | Low-Medium | Hardy, great climbing vine, boosts humidity | Virtually indestructible, best starter plant |
| Bromeliads | Medium | Water-catching cups, hiding spots | Geckos love sleeping in the leaf wells |
| Ficus pumila | Low-Medium | Creeping vine, covers background | Creates a lush, living wall effect |
| Bird's Nest Fern | Low | Large fronds for climbing and resting | Loves humidity, does well in terrariums |
| Dracaena | Medium | Sturdy branches for climbing | Slow growing, long lasting |
| Philodendron | Low-Medium | Trailing vines, large leaves for resting | Multiple varieties work well |
Important: Always research plant safety before adding to your enclosure. Avoid plants treated with pesticides or fertilizers. Rinse all plants thoroughly and quarantine for 2 weeks before introducing. Avoid toxic plants like ivy, dieffenbachia, and oleander.
Temperature & Humidity
One of the best things about crested geckos is that they thrive at room temperature. Unlike many reptiles that require expensive heating equipment, cresties prefer moderate temperatures that match most homes.
Temperature Requirements
Critical Warning: Crested geckos are extremely heat-sensitive. Prolonged exposure to temperatures above 85°F can cause heat stress, organ damage, and death. If your home gets hot in summer, consider air conditioning, fans, or relocating the enclosure to a cooler room.
Humidity Requirements
- Target range: 60-80% relative humidity
- Misting schedule: Mist heavily in the evening and lightly in the morning
- Dry-out period: Allow humidity to drop to 50-60% between mistings to prevent bacterial/fungal growth
- Monitoring: Use a digital hygrometer (not analog dial types, which are inaccurate)
- Live plants: Help maintain humidity naturally between mistings
Lighting
Crested geckos do not require specialized lighting to survive, but providing appropriate lighting improves their overall health and encourages natural behavior patterns.
- Day/night cycle: 12 hours of light, 12 hours of dark. Consistency is key for their circadian rhythm.
- Low-level UVB (optional but beneficial): A 5% or 2% UVB bulb (like Arcadia ShadeDweller) can improve calcium metabolism and vitamin D3 synthesis. Position it with a 6-8 inch distance from basking spots.
- LED plant lights: If you have live plants, a low-output LED grow light serves dual purpose for plant growth and ambient lighting.
- Avoid: Bright, high-output lights that can stress nocturnal geckos. Never use colored heat lamps at night.
Diet & Feeding
Crested geckos are omnivores that eat a combination of fruit, nectar, and insects in the wild. In captivity, they can thrive on commercially prepared diets supplemented with occasional live insects. This makes them one of the easiest reptiles to feed.
Commercial Crested Gecko Diet (CGD)
CGD is a powdered complete diet mixed with water to form a paste. It should be the primary food source, offered 3-4 times per week in a small elevated cup.
Top CGD Brands
- Pangea: Wide variety of flavors, excellent nutrition. Most recommended.
- Repashy: The original CGD formula by Allen Repashy. Proven track record.
- Leapin Leachie: Premium option with high fruit content.
- Zoo Med: Budget-friendly option, widely available.
Feeding Tips
- Mix to ketchup/applesauce consistency
- Offer in elevated cups near the top of the enclosure
- Replace uneaten food every 24-48 hours
- Rotate flavors to prevent pickiness
Live Insect Supplementation
While not strictly required if using quality CGD, offering live insects 1-2 times per week provides enrichment and additional protein, especially for growing juveniles and breeding females.
- Best options: Dubia roaches, black soldier fly larvae (BSFL/Nutrigrubs), small crickets
- Occasional treats: Waxworms, silkworms (higher fat, use sparingly)
- Sizing rule: Insects should be no larger than the space between the gecko's eyes
- Dusting: Lightly dust insects with calcium powder (with D3 if no UVB, without D3 if UVB is provided)
- Gut-loading: Feed insects nutritious greens and vegetables 24 hours before offering to your gecko
Feeding Schedule by Age
| Age | CGD Frequency | Insects |
|---|---|---|
| Hatchling (0-3 mo) | Every other day | 2-3 small insects 1x/week |
| Juvenile (3-12 mo) | Every other day | 3-5 insects 1-2x/week |
| Subadult (12-18 mo) | 3-4x per week | 5-7 insects 1x/week |
| Adult (18+ mo) | 3x per week | 5-8 insects 1x/week (optional) |
Hydration
Crested geckos primarily drink water droplets from misted surfaces rather than from standing water dishes. Proper hydration is closely tied to your misting routine.
- Misting is key: Mist enclosure walls and foliage heavily each evening. The gecko will lick droplets from leaves and glass.
- Water dish: Always provide a shallow water dish as a backup. Some geckos do learn to drink from dishes.
- Water quality: Use dechlorinated or spring water. Avoid distilled water (lacks minerals).
- Dehydration signs: Wrinkled skin, sunken eyes, lethargy, dry-looking skin, and infrequent shedding.
Supplement Schedule
Proper supplementation prevents metabolic bone disease (MBD) and ensures your crested gecko gets all the vitamins and minerals it needs. Your supplement schedule depends on whether you provide UVB lighting, as UVB allows geckos to synthesize their own vitamin D3.
Supplement Schedule: Without UVB
| Supplement | Frequency | Application |
|---|---|---|
| Calcium with D3 | Every feeding (dust insects) | Light dusting on all feeder insects |
| Multivitamin | 1-2x per month | Dust insects or mix into CGD |
| Plain Calcium (no D3) | Leave in dish 24/7 | Small bottle cap in enclosure for self-serve |
Supplement Schedule: With UVB
| Supplement | Frequency | Application |
|---|---|---|
| Calcium without D3 | Every feeding (dust insects) | Light dusting on all feeder insects |
| Multivitamin with D3 | 1-2x per month | Dust insects or mix into CGD |
| Plain Calcium (no D3) | Leave in dish 24/7 | Small bottle cap in enclosure for self-serve |
Recommended Supplement Brands
Repashy Calcium Plus
All-in-one calcium + vitamin supplement. Very popular choice. Can be used as the sole supplement when dusting insects at every feeding. Simplifies the routine.
Arcadia EarthPro-A
Designed for use with UVB setups. Contains bee pollen and carotenoids. Pair with Arcadia CalciumPro Mg for a complete regimen. Premium quality, used by professional breeders.
Pangea Calcium
Available with and without D3. Finely milled for excellent adhesion to insects. Affordable and widely available. A solid everyday dusting option.
Note: If you feed a high-quality CGD like Pangea or Repashy as the primary diet, these already contain calcium and vitamins. Additional supplementation is mainly needed when feeding live insects. Over-supplementation with D3 can cause toxicity, so avoid double-dosing if your CGD and insect dust both contain D3.
Handling & Taming
Crested geckos are generally docile and become comfortable with regular, gentle handling. However, they can be skittish and jumpy, especially when young. Patience and consistency are key to building trust.
Getting Started
- Settling in period: Wait 1-2 weeks after bringing your gecko home before attempting to handle. Let them adjust to their new environment.
- Start slow: Begin with 5-minute sessions, gradually increasing to 10-15 minutes as your gecko becomes comfortable.
- Best time: Handle during evening hours when they are naturally more alert and active.
- Hand walking: Let the gecko walk from hand to hand. Move slowly and stay low to a soft surface in case of jumps.
- Never grab: Scoop gently from below. Never grab from above (predator response) or restrain forcefully.
Reading Body Language & Stress Signals
Calm / Comfortable Signs
- Slow, deliberate movements on your hands
- Relaxed body posture, not tense or rigid
- Licking the air or your hand (exploring)
- Eyes open and scanning calmly
- Voluntarily climbing onto your hand
- Soft chirping sounds (contentment)
Stressed / Fearful Signs
- Rapid breathing or panting
- Attempting to leap or bolt away
- Flattening body against a surface
- Tail waving or curling tightly
- Biting or opening mouth defensively
- Barking or loud squeaking sounds
- Dropping tail (extreme stress)
Taming Timeline Expectations
| Week | Goal | What to Expect |
|---|---|---|
| Week 1-2 | No handling, settling in | Gecko hides frequently, may refuse food initially |
| Week 3-4 | Place hand in enclosure | Let gecko investigate your hand without forcing contact |
| Week 5-6 | Short handling (5 min) | Gecko may jump but begins tolerating contact |
| Week 7-10 | Extended handling (10-15 min) | Gecko walks calmly, less jumping, may perch on you |
| Month 3+ | Fully tame | Confident handling, voluntarily climbs on, minimal stress |
Tail Drop Warning
Crested geckos can drop their tails if stressed or grabbed. Unlike leopard geckos, crested gecko tails do not regenerate. A tailless crested gecko (called a "frogbutt") is perfectly healthy but the tail will never grow back. Handle gently to prevent this.
Shedding
Crested geckos shed their skin regularly as they grow. Healthy geckos complete their shed quickly, often overnight, and eat the shed skin (this is completely normal and provides nutrients).
- Frequency: Juveniles shed every 1-2 weeks. Adults shed every 2-4 weeks.
- Signs of upcoming shed: Dull, grayish appearance, reduced appetite, seeking humid areas.
- Humidity is critical: Maintain 70-80% humidity during shedding. Extra misting may be needed.
- Stuck shed: Check toes, tail tip, and around eyes for retained shed. A moist paper towel soak can help loosen stuck pieces.
- When to worry: Frequent stuck sheds indicate humidity is too low or the gecko is dehydrated.
Health & Common Issues
With proper husbandry, crested geckos are generally healthy reptiles. However, knowing the signs of common health issues allows you to catch problems early.
Signs of a Healthy Gecko
- Clear, bright eyes with full crests
- Smooth skin, clean vent area
- Good appetite, eating regularly
- Active and alert during evening hours
- Plump, rounded tail (if present)
- Fires up/down (color changes with mood)
- Smooth, complete sheds
- Firm, well-formed droppings
Warning Signs - See a Vet
- Stuck shed, especially around toes/eyes
- Lethargy, hiding constantly during active hours
- Significant weight loss or sunken belly
- Mouth gaping, mucus discharge, wheezing
- Swollen or deformed limbs (MBD)
- Watery or bloody droppings
- Refusal to eat for more than 2 weeks
- Lumps, lesions, or discoloration on skin
Common Health Issues
Metabolic Bone Disease (MBD)
Caused by calcium/vitamin D3 deficiency. Symptoms include soft or deformed jaw, trembling, inability to climb, and swollen limbs. Prevention: Proper supplementation and optional UVB lighting. MBD is preventable but can be irreversible if advanced.
Respiratory Infections
Caused by consistently low temperatures, excessive humidity without ventilation, or bacterial/fungal growth. Symptoms include wheezing, open-mouth breathing, mucus around nose/mouth. Requires veterinary treatment with antibiotics.
Parasites
Internal parasites (pinworms, coccidia) and external parasites (mites) can affect crested geckos, especially wild-caught or pet store animals. Annual fecal exams are recommended. Quarantine all new geckos for 30-90 days.
Floppy Tail Syndrome
Common in crested geckos that sleep on glass walls. The tail hangs over the back, potentially affecting the pelvis over time. Provide plenty of horizontal resting surfaces and ledges to prevent this.
Egg Binding (Dystocia)
Occurs in female geckos when eggs cannot be passed normally. Signs include prolonged straining, lethargy, loss of appetite, and visible swelling. Caused by insufficient calcium, dehydration, or lack of an appropriate lay box. Egg binding is a veterinary emergency requiring immediate professional treatment. Always provide a moist lay box with 3-4 inches of substrate for breeding females.
Finding a Reptile Vet
Not all veterinarians are experienced with reptiles. Finding a qualified reptile vet before an emergency is critical. Here's how:
- ARAV Directory: The Association of Reptilian and Amphibian Veterinarians maintains a searchable vet directory at arav.org
- Ask breeders: Local reptile breeders and expos are excellent resources for vet recommendations
- Exotic animal hospitals: Search for "exotic animal vet" or "herp vet" in your area
- Telehealth options: Some reptile vets offer virtual consultations for non-emergency questions
- Emergency fund: Set aside $200-500 for unexpected vet visits. Reptile exams typically cost $50-150, treatments can be much more.
Quarantine Protocol for New Geckos
Every new gecko should be quarantined before being introduced near your existing collection. This protects your other animals from potential pathogens.
- Duration: Minimum 30 days, ideally 60-90 days
- Separate room: Keep quarantined geckos in a completely different room if possible
- Simple setup: Paper towel substrate, minimal decor, easy to sanitize
- Handle last: Always care for quarantined geckos last. Wash hands and change clothes between animals.
- Fecal testing: Submit a fresh fecal sample to your reptile vet within the first 2 weeks
- Monitor closely: Watch for signs of respiratory infections, parasites, stuck sheds, or abnormal behavior
Fecal Testing Schedule
| When | Reason | What They Check |
|---|---|---|
| New acquisition (within 2 weeks) | Baseline health check | Pinworms, coccidia, flagellates, Cryptosporidium |
| Annually (established pets) | Routine wellness | Internal parasites, bacterial overgrowth |
| If symptoms appear | Diagnostic | Watery/bloody stool, weight loss, lethargy |
| Before breeding season | Pre-breeding health | Ensure breeding animals are parasite-free |
Cleaning & Maintenance
Keeping your crested gecko's enclosure clean is essential for preventing illness and maintaining a healthy environment. Your cleaning routine will differ depending on whether you have a bioactive or non-bioactive setup.
Daily Tasks
- ✅ Remove uneaten CGD and replace food cup
- ✅ Spot clean any visible droppings
- ✅ Mist enclosure (evening heavy mist, morning light mist)
- ✅ Check water dish and refill with fresh water
- ✅ Quick visual health check on your gecko
- ✅ Check temperature and humidity readings
Weekly Tasks
- ✅ Wipe down glass walls to remove water spots and smudges
- ✅ Clean and sanitize food and water dishes
- ✅ Remove any shed skin pieces left behind
- ✅ Check plants for dead leaves or mold spots
- ✅ Inspect decor for mold or excessive buildup
- ✅ Replace paper towel substrate (non-bioactive setups)
Monthly Tasks
- ✅ Deep clean non-bioactive enclosures (full substrate change)
- ✅ Sanitize all decor with reptile-safe disinfectant or diluted vinegar
- ✅ Check and replace any worn cork bark or decor
- ✅ Calibrate thermometers and hygrometers
- ✅ Weigh your gecko and record in a log
- ✅ Inspect enclosure seals and doors for proper function
Bioactive vs. Non-Bioactive Maintenance
Bioactive Maintenance
- Cleanup crew handles most waste
- No full substrate changes needed
- Add leaf litter as it breaks down
- Supplement cleanup crew if population drops
- Prune and maintain live plants as needed
- Only deep clean if setup fails (rare)
Non-Bioactive Maintenance
- Full substrate replacement monthly
- Sanitize entire enclosure during changes
- More frequent spot cleaning required
- Replace artificial plants when faded/dirty
- Higher ongoing maintenance effort
- Lower initial setup cost
Mold Prevention Tips
- Ventilation: Ensure adequate airflow with screen tops or ventilation panels. Stagnant, humid air breeds mold.
- Dry-out cycles: Allow the enclosure to dry to 50-60% humidity between mistings. Constant 80%+ humidity invites mold.
- Remove uneaten food: Old CGD is a prime mold source. Replace every 24-48 hours without exception.
- Springtails: In bioactive setups, springtails are your best defense against mold. They consume mold spores before they spread.
- Charcoal layer: Horticultural charcoal in your substrate mix helps absorb excess moisture and prevent fungal growth.
- Spot treatment: Small mold spots can be removed with a paper towel. If mold persists, check your ventilation and misting schedule.
Common Beginner Mistakes
Even well-intentioned keepers make mistakes when starting out. Here are the most common errors we see with crested gecko care, and how to avoid them.
1. Keeping the enclosure too hot
Crested geckos are not tropical "heat lovers." Temperatures above 82°F stress them, and above 85°F can be fatal. They thrive at room temperature (72-78°F). No heat lamp is usually necessary.
2. Not allowing humidity to cycle
Keeping humidity at a constant 80%+ causes respiratory infections and mold. Humidity should spike to 80% after misting, then dry down to 50-60% before the next mist. The cycle is critical.
3. Using calcium sand or loose sand substrate
Calcium sand (marketed as "digestible") and loose sand are impaction risks. Crested geckos don't need sand at all. Stick with paper towels, coconut fiber, or a bioactive ABG mix.
4. Cohabitation (housing geckos together)
Crested geckos are solitary animals. Housing two together causes chronic stress, competition for food, fighting, injuries, and unexpected breeding. Never house two males together. Even male/female pairs should only be together temporarily for breeding.
5. Enclosure too large for babies
Baby crested geckos (under 10g) struggle to find food in large enclosures. They should be housed in small containers (6-12 qt tubs or 12x12x18 tanks) until they reach 10-15 grams.
6. No calcium supplementation
Even with quality CGD, geckos eating insects need calcium dusting. Without supplementation, metabolic bone disease (MBD) develops, causing deformed bones, tremors, and inability to climb. MBD is preventable but often irreversible.
7. Using analog thermometers/hygrometers
Dial-type analog gauges sold at pet stores are notoriously inaccurate, sometimes off by 10-20%. Invest in a quality digital thermometer/hygrometer combo (Govee, AcuRite, or similar) for accurate readings.
8. Handling too soon or too much
New geckos need 1-2 weeks to settle in before handling. Handling a stressed gecko causes tail drops, food refusal, and chronic anxiety. Start with short 5-minute sessions and build up gradually.
9. Feeding only one brand/flavor of CGD
Geckos fed only one flavor can become picky and refuse anything else. Rotate between 2-3 brands and multiple flavors from the start. Mix flavors occasionally to prevent fixation on a single taste.
10. Not providing vertical climbing space
Crested geckos are arboreal. A horizontally-oriented tank (like a standard fish aquarium) is completely wrong for them. They need tall, vertically-oriented enclosures with lots of branches, vines, and foliage to climb.
11. Breeding too young or without a plan
Breeding females before 18 months and 38g risks their health. Each female can produce 8-16+ babies per season. Without homes lined up and the resources to raise hatchlings, breeding quickly becomes overwhelming.
12. Skipping quarantine for new geckos
Introducing a new gecko directly to your collection risks spreading parasites, bacteria, or viruses. Always quarantine new arrivals for 30-90 days in a separate room with its own supplies and equipment.
Age-Specific Care Guide
Crested gecko care needs change as they grow. What works for a hatchling is different from what an adult needs. Understanding these developmental stages helps you provide optimal care at every age.
Hatchlings (0-10g, 0-4 months)
Housing
- Small containers (6-12 qt tubs or small Kritter Keepers)
- Paper towel substrate for easy monitoring
- Minimal decor, a few fake leaves and a small hide
- Magnetic ledge for elevated food cup
Feeding & Care
- CGD every other day in a small cup
- 2-3 pinhead crickets or small BSFL 1x/week
- Mist 2x daily, hatchlings dehydrate easily
- Weigh weekly to ensure growth
- No handling for first 2-3 weeks minimum
Juveniles (10-25g, 4-12 months)
Housing
- 12x12x18 enclosure minimum
- Can transition to coconut fiber or bioactive substrate
- Add more branches, vines, and foliage
- Multiple hiding spots at different heights
Feeding & Care
- CGD every other day
- 3-5 appropriately sized insects 1-2x/week
- Begin gentle handling sessions (5-10 min)
- Weigh bi-weekly, expect steady growth
- Expect frequent shedding (every 1-2 weeks)
Subadults (25-35g, 12-18 months)
Housing
- 18x18x24 enclosure (can move to adult size)
- Full decor setup with climbing opportunities
- Bioactive setup ideal at this stage
- Provide both high and low temperature zones
Feeding & Care
- CGD 3-4x per week
- 5-7 insects 1x/week
- Growth rate slows; weigh monthly
- Can begin sexing (males show hemipenal bulges)
- Handling sessions up to 15 minutes
Adults (35g+, 18+ months)
Housing
- 18x18x24 minimum, 24x18x36 ideal
- Full bioactive setup recommended
- Provide lay box for females (even unbred females can lay infertile eggs)
- Stable, enriched environment
Feeding & Care
- CGD 3x per week
- Insects 1x/week (optional for non-breeders)
- Monitor weight monthly; adults should maintain 35-55g
- Annual vet checkup and fecal exam
- Watch for obesity in non-breeding adults
Weight Tracking Milestones
| Age | Expected Weight | Growth Rate | Notes |
|---|---|---|---|
| Hatching | 1.5-2g | - | May not eat for first 3-5 days (absorbing yolk) |
| 1 month | 2-4g | ~1g/month | Slow initial growth is normal |
| 3 months | 4-8g | ~1-2g/month | Growth accelerating |
| 6 months | 8-15g | ~2-3g/month | Peak growth period |
| 9 months | 15-25g | ~2-3g/month | Sexing becomes possible |
| 12 months | 20-35g | ~1-2g/month | Growth slowing, approaching subadult |
| 18 months | 30-45g | Minimal | Approaching adult size |
| 24+ months | 35-55g | Stable | Full adult weight, growth complete |
Tip: Growth rates vary significantly between individuals. Some geckos are naturally slow growers. Consistent feeding and proper temperatures are more important than hitting exact weight targets. If your gecko is eating, active, and maintaining weight, they are likely healthy regardless of size.
Socialization & Enrichment
While crested geckos are not social animals in the traditional sense, they benefit greatly from environmental stimulation and enrichment. A well-enriched gecko is more active, healthier, and displays more natural behaviors.
Environmental Enrichment Ideas
Physical Enrichment
- Rearrange branches and vines monthly to create new climbing paths
- Add new cork bark pieces or bamboo tubes periodically
- Vary the height and placement of feeding ledges
- Include textured surfaces (rough bark, smooth bamboo, leafy vines)
- Create "tunnels" with curved cork bark
Feeding Enrichment
- Place CGD in different locations each feeding night
- Offer live insects for hunting stimulation
- Smear a thin layer of CGD on leaves or bark for foraging
- Rotate between 3-4 CGD flavors and brands
- Offer occasional safe fruit treats (mashed banana, mango)
Rearranging Decor
Changing the layout of your enclosure every 4-6 weeks mimics the natural variability of a forest environment. This encourages exploration and prevents boredom. When rearranging, keep at least one or two familiar items in place so your gecko still has a sense of security. Avoid rearranging during shedding or if your gecko is visibly stressed.
Safe Out-of-Enclosure Exploration
Supervised exploration outside the enclosure provides mental stimulation and exercise. Follow these safety rules:
- Gecko-proof the room: Close doors and windows, block gaps behind furniture, remove other pets
- Stay close: Never leave your gecko unattended. They can jump surprisingly far and hide in tiny spaces
- Avoid cold drafts: Ensure the room is within 70-80°F during exploration time
- Houseplants: Many common houseplants are toxic to reptiles. Move them out of reach or out of the room
- Time limit: Keep sessions to 15-30 minutes to avoid temperature stress
- Natural climbing: Supervised time on a large potted plant or a "gecko tree" (safe branches on a stand) is excellent enrichment
Morphs & Colors
Crested geckos come in an incredible variety of colors and patterns. Unlike leopard geckos where morphs are genetically defined, crested gecko "morphs" are classified by visual traits (color, pattern, and structure). Selective breeding has produced stunning combinations.
Common Morph Types
Flame
Cream or light dorsal stripe with darker sides. One of the most common and affordable morphs.
Harlequin
Heavy patterning on the sides with contrasting cream or white lateral markings. More pattern than a flame.
Extreme Harlequin
Maximum lateral patterning covering 60%+ of the body. Highly contrasting with bold pattern coverage. Premium pricing.
Dalmatian
Covered in spots (dalmatian spots). Super Dalmatians have 100+ spots. Very popular morph.
Pinstripe
Raised, cream-colored scales running along the dorsal crests. Can be partial or full pinstripe.
Lilly White
A co-dominant mutation producing bright white sides and pattern. One of the most sought-after morphs.
Tricolor
Three distinct colors visible. Often red/orange base with cream and dark brown pattern. Highly valued.
Phantom
Dark base color with subtle, shadowy patterning that appears and disappears. Ghost-like contrast between fired up and fired down states.
Cappuccino
A newer co-dominant mutation producing warm brown tones with unique patterning. Super Cappuccino (homozygous) is extremely rare and valuable.
Axanthic
Reduced yellow/orange pigmentation resulting in a silvery, gray, or lavender appearance. True axanthics are rare in crested geckos.
Whiteout
Extensive white or cream coloring covering most of the body. Often paired with pinstripe or harlequin traits for striking combinations.
Color Variations
| Color | Description | Rarity |
|---|---|---|
| Red | Deep red to cherry tones when fired up. Highly desirable, especially in tricolor combos. | Uncommon |
| Orange | Vibrant orange base, often seen in flame and harlequin morphs. One of the most popular colors. | Common |
| Yellow | Bright lemon to golden yellow. Can range from pastel to saturated. Striking when paired with dark pattern. | Moderate |
| Chocolate | Rich, dark brown base. Creates beautiful contrast with cream patterning in harlequin combos. | Common |
| Olive | Muted green-brown tones. Natural-looking, often found in wild-type or flame morphs. | Common |
| Buckskin | Tan to light brown, similar to leather. Subtle and warm. Common base color for many morph combos. | Common |
| Cream/White | Light cream to near-white. Often seen in pattern areas rather than base color. Key in Lilly Whites. | Common (as pattern) |
| Black | Very dark, near-black fired up coloring. True black is rare. Most "black" geckos are very dark brown or charcoal. | Rare |
Fired Up vs. Fired Down
Crested geckos change color based on mood, time of day, and environmental conditions. "Fired up" is their darker, more vibrant coloring (usually at night when active). "Fired down" is their lighter, paler resting color. Both are completely normal. When purchasing a gecko, ask to see photos of both states to know the full color range.
Breeding Basics
Crested geckos are prolific breeders in captivity. Before considering breeding, ensure you have the resources, knowledge, and homes for potential offspring.
Prerequisites for Breeding
- Breeding age: Females should be at least 18 months old and 38+ grams. Males can breed earlier but should also be mature.
- Sexing: Males develop visible hemipenal bulges at the base of the tail and preanal pores by 15-20 grams.
- Egg laying: Females lay 2 eggs every 4-6 weeks during breeding season (spring through fall). Provide a lay box with moist substrate.
- Incubation: 60-90 days at 72-78°F. Higher temperatures produce faster hatches but are riskier.
- Cool down period: A 2-3 month rest period (65-70°F) in winter allows females to recover and produces better results.
Genetics Basics
Co-Dominant Traits
- Lilly White: One copy produces the Lilly White phenotype. Two copies (super form) may cause lethal effects in some pairings.
- Cappuccino: One copy produces the Cappuccino look. Super Cappuccino (homozygous) is extreme and rare.
- Co-dominant traits are visible with just one allele from either parent
- Never breed two Lilly Whites together (risk of lethal super form)
Line-Bred / Polygenic Traits
- Most crested gecko morphs are polygenic (controlled by multiple genes)
- Color intensity, pattern coverage, and structure are selectively bred over generations
- No simple dominant/recessive inheritance for most visual traits
- Breeding two high-quality parents increases odds of quality offspring but is not guaranteed
Egg Incubation Setup
- Container: Small deli cup or plastic container with a few pin-sized ventilation holes in the lid
- Medium: Damp perlite, vermiculite, or HatchRite. The medium should be moist but not dripping (squeeze test: a few drops when squeezed firmly).
- Placement: Bury eggs halfway in the medium. Do not rotate eggs once placed.
- Temperature: 72-78°F for healthy development. Room temperature incubation works well in most homes.
- Duration: 60-90 days depending on temperature. Cooler temps = longer incubation but generally healthier hatchlings.
- Monitoring: Check moisture levels weekly. Mist lightly if medium appears dry. Watch for mold (remove immediately if spotted on eggs).
- Candling: After 2-3 weeks, you can candle eggs with a flashlight to check for veins (fertile) vs. yellow/opaque (infertile).
Hatchling Care
Newly hatched crested geckos are tiny (1.5-2g) and delicate. They typically won't eat for the first 3-5 days while absorbing remaining yolk. After that, offer small amounts of CGD in a bottle cap and tiny insects once weekly. House in small, simple enclosures with paper towel substrate and a few pieces of fake foliage for cover. Mist twice daily as hatchlings are prone to dehydration.
When NOT to Breed
Breeding comes with significant responsibility. Do not breed if:
- Your female is under 18 months old or under 38 grams
- Either parent has unknown genetics or health issues
- You do not have homes lined up for 8-16+ potential hatchlings per season
- You cannot afford the supplies (incubation containers, hatchling tubs, extra CGD, potential vet bills)
- You are breeding solely for profit (the market is saturated with normal morphs)
- Your female has not had a proper cool-down recovery period between seasons
- Either gecko shows signs of MBD, parasites, or other health conditions
Responsible breeding: Only breed healthy, unrelated geckos with known genetics. Have a plan for all hatchlings before breeding. Each female can produce 8-16+ babies per season.
