Leopard geckos need a 20-gallon minimum enclosure (40-gallon+ recommended), a three-zone temperature gradient (hot hide 88–92°F, warm side 80–85°F, cool side 70–75°F), ambient humidity of 30–40%, and a moist hide at 70–80% for shedding. Feed live insects dusted with calcium and D3 to prevent metabolic bone disease. Handle gently — never grab the tail. They live 15–20 years.
Leopard gecko species overview
Eublepharis macularius — the leopard gecko — is native to arid and semi-arid zones across Afghanistan, Pakistan, northwestern India, Iran, and Nepal. In the wild they live in rocky desert and dry grassland, coming out at dusk and dawn to hunt. That crepuscular rhythm carries into captivity: your leo will be most active in the evenings and early morning, which suits most keeper schedules well.
Adults reach 7–11 inches (18–28 cm), with females typically staying at the smaller end and large males occasionally exceeding 10 inches. Hatchlings start at 3–4 inches (7–10 cm) and put on size quickly in the first year. In captivity, with correct husbandry, leopard geckos live 15–20 years — males often outlive females, and well-cared-for individuals can reach 20+ years. ReptiFiles has tracked population-level data on captive longevity; it consistently supports the 15–20 year range for well-kept animals.
What sets leopard geckos apart from most geckos you’ll encounter: they belong to the family Eublepharidae, the “eyelid geckos.” They can blink and fully close their eyes — genuinely unusual in the gecko world. They also lack the adhesive toe pads that let most geckos climb vertical glass. Leopard geckos are strictly ground-dwelling animals; a longer tank footprint matters far more than height.
Temperament-wise, they’re docile by default, slow to bite, and genuinely tolerant of regular handling once settled in. Widely considered the most beginner-friendly reptile available, and that reputation is well earned. Most pet leopard geckos are captive-bred — CB animals acclimate better, carry fewer parasites, and are simply better candidates for a first gecko. Our where to buy a leopard gecko guide covers what to look for when choosing a breeder.
Over 100 morphs exist, including three genetically incompatible albino strains (Tremper, Bell, and Rainwater/Las Vegas) — morph selection doesn’t affect care requirements, and the full breakdown is in our leopard gecko morph guide. If you’re still weighing species options, our leopard gecko vs crested gecko and leopard gecko vs bearded dragon comparisons lay out the key practical differences.

Enclosure setup overview
Start with a 20-gallon tank minimum for one adult. A 40-gallon+ enclosure with a longer footprint — not extra height — is the real upgrade. Leopard geckos don’t climb; floor space is what matters. A 36″×18″ or 48″×18″ footprint gives a proper thermal gradient and room to behave naturally. Most keepers go straight to an adult-sized setup.
The three-hide rule
Every leopard gecko enclosure needs three distinct hides, each serving a specific role:
- Warm hide: positioned on the warm side, over or near the heat source; this is your gecko’s primary thermoregulation retreat — warm belly, covered and secure
- Cool hide: on the opposite end of the enclosure; a retreat for when the gecko wants to cool down or just wants to rest without heat
- Moist hide: a third enclosed hide filled with damp sphagnum moss or moist paper towels, held at 70–80% internal humidity for shedding support
Hides should fit the gecko snugly — body touching the walls on multiple sides. A hide that’s too large gives no sense of security and gets ignored. See our hides setup guide for sizing, placement, and what materials hold humidity reliably.
Decor and enrichment
A functional enclosure doesn’t have to be bare. Enrichment reduces stress and encourages natural behaviour — leopard geckos explore, investigate, and actively use a well-set-up space.
What works: Artificial plants or drought-tolerant succulents add visual cover without raising enclosure humidity. Low, flat climbing surfaces — cork bark rounds, flat stones, textured slate — let geckos move at different levels without the fall risk of tall branches. Textured backgrounds or cork tiles add grip and visual interest. A second or third hide beyond the three-hide minimum is always well-used.
What to avoid: Sharp-edged décor or rough-cut rocks that can abrade skin. Any loose, small items your gecko can ingest — decorative pebbles, synthetic plants with removable parts, or gravel fill. Anything that traps moisture in the main enclosure can introduce mold risk; keep the moist hide the only consistently damp surface.
Substrate
Safe beginner options: paper towels (best for hatchlings and sick animals), ceramic tile, and reptile carpet. Bioactive setups with organic topsoil and leaf litter are an excellent choice for more experienced keepers. Our leopard gecko substrate guide covers each option’s pros, cons, and safety rating.
⚠️ Impaction warning: Avoid loose particle substrates. Sand, calcium sand, and walnut shell are impaction hazards — if ingested, they can cause a life-threatening intestinal blockage. This risk is highest in juveniles and sick animals. Starting with tile or paper towel is the safest approach; switch to bioactive only when you’re ready to maintain it properly.
A water dish belongs on the cool side; change it every 2–3 days. UVB lighting is not biologically required for survival, but low-level UVB is increasingly recommended by reptile vets — full guidance in our lighting and UVB guide. Cohabitation is generally not recommended; males fight, and a male + female pairing creates persistent breeding stress.

What you’ll need: equipment checklist
Before your gecko comes home, have these ready. Most problems in the first year trace back to something on this list being skipped or substituted:
- Enclosure: 20-gallon minimum; 40-gallon+ recommended (36″×18″ or 48″×18″ footprint — longer, not taller)
- Under-tank heater (UTH): sized to cover roughly one-third of the floor on the warm end
- Thermostat: connects to the UTH; maintains probe-verified surface temperature — not optional
- 3 hides: warm hide (on heat side), cool hide (opposite end), moist hide (sphagnum moss or damp paper towel inside)
- Substrate: paper towels or ceramic tile for beginners; bioactive mix for experienced keepers
- Water dish: shallow, heavy enough not to tip; placed on the cool side
- Digital probe thermometer or IR gun: for checking actual substrate temperatures, not ambient air
- Digital hygrometer: to monitor ambient humidity (target: 30–40%)
- Calcium + D3 powder: for dusting feeder insects before each feeding
- Calcium-only dish (no D3): small dish placed in the enclosure for self-supplementation between feedings
- Feeding tongs: for hand-feeding insects and keeping fingers out of strike range during feeding time
- Misting bottle: used only on the moist hide contents — never mist the enclosure directly
Temperature and heating
Leopard geckos are ectotherms — they can’t generate body heat internally, so the enclosure needs to provide a reliable gradient they can move through across the day and night. A single “temperature setting” doesn’t work. What you’re building is a range.
Temperature gradient
| Zone | Temperature (°F) | Temperature (°C) |
|---|---|---|
| Hot hide | 88–92°F | 31–33°C |
| Warm side | 80–85°F | 27–29°C |
| Cool side | 70–75°F | 21–24°C |
The hot hide is your gecko’s thermoregulation anchor — belly heat, supplied by an under-tank heater (UTH) placed beneath the warm end of the enclosure. This is the primary heating method for leopard geckos, and no overhead basking lamp is required.
A thermostat is mandatory. An unregulated UTH can reach temperatures well above what the packaging suggests — high enough to cause thermal burns through substrate. Every UTH must run through a thermostat. A rheostat (dimmer switch) is not a substitute; it controls wattage input, not actual surface temperature. Thermostats are inexpensive and there is no valid reason to skip one.
Verify temperatures with a digital probe thermometer or IR gun at substrate level. A dial thermometer stuck to the glass is not accurate.
→ Full guide: Leopard Gecko Temperature and Heating: Gradients, UTHs, and Thermostat Setup
Humidity: ambient vs. moist hide
This is where new keepers get confused most often. Leopard geckos come from arid environments — you do not want to raise overall enclosure humidity.
Ambient enclosure humidity: 30–40%. Measure with a digital hygrometer. If your climate runs higher, increase ventilation.
Moist hide humidity: 70–80% internally. The moist hide is a separate, dedicated shedding station — a small enclosed hide packed with damp sphagnum moss or moist paper towels. The humidity inside that specific hide is elevated to help the gecko shed cleanly. The rest of the enclosure stays dry.
| Ambient enclosure | Moist hide (interior) | |
|---|---|---|
| Target humidity | 30–40% | 70–80% |
| Purpose | Normal daily environment | Shedding support |
| How to achieve | Adequate ventilation; no misting | Damp sphagnum moss or moist paper towels inside a closed hide |
Misting the whole enclosure to “help with shedding” is the wrong approach — it creates respiratory problems and substrate mold. One localized humid retreat does the job without raising ambient moisture. For the full shedding process and what to monitor, see our leopard gecko shedding guide.
Feeding: diet overview
Leopard geckos are strict insectivores. No plant matter, no fruit. Their digestive system isn’t built for it, and feeding vegetation is a mistake regardless of what some sources suggest.
Crickets, mealworms, dubia roaches, and hornworms all make solid staple feeders. Superworms are appropriate for adults. Waxworms are high in fat and fine as an occasional treat — not a staple. Rotating between two or three different staple insects gives a better nutritional profile than relying on just one.
Prey size: nothing wider than the space between your gecko’s eyes. Feeding prey that’s too large puts unnecessary stress on the digestive system and raises impaction risk. When in doubt, go smaller.
All feeders should be gut-loaded 24–48 hours before you offer them. A gut-loaded cricket passes its nutritional load on to your gecko; an empty cricket passes almost nothing of value. This step is separate from supplementation — both matter and neither replaces the other. Full gut-loading guidance in our gut-loading guide.
Feeding frequency
| Age group | Feeding frequency | Notes |
|---|---|---|
| Juvenile (under 6 months) | Daily or every other day | Growing rapidly; high energy demand |
| Adult (6+ months) | Every 2–3 days | Body condition guides frequency |
Feed to body condition as well as schedule. A lean adult can be fed on the shorter end of that range; a gecko carrying noticeable fat reserves in the tail can be stretched toward every 3 days. The tail thickness is one of the better health indicators for this species.

Calcium and supplementation — critical for health
Get supplementation right and you prevent the single most common preventable disease in captive leopard geckos. Get it wrong and you’ll be dealing with a sick gecko months or years down the road when the damage has already accumulated.
Dust feeder insects with a calcium + D3 powder before each feeding — 2–3 times per week for adults, every feeding for juveniles. Keep a small dish of plain calcium powder (no D3) in the enclosure at all times; geckos self-supplement from this as needed. A multivitamin supplement 1–2 times per month rounds out the nutritional profile.
D3 is what enables calcium absorption. Without it, dietary calcium passes through unused. Most captive geckos under standard lighting need D3 in their supplementation routine — which is part of why low-level UVB is increasingly being added to setups as a secondary D3 source.
⚠️ MBD prevention: Metabolic bone disease (MBD) is the most common preventable disease in captive leopard geckos. It develops when geckos don’t receive sufficient calcium and vitamin D3 — both essential for bone mineralization. MBD causes progressive bone softening, tremors, and eventual inability to walk. It is 100% preventable with correct supplementation: dust feeder insects with calcium + D3 powder and keep a calcium-only dish available in the enclosure at all times.
Do not rely on gut-loading alone to deliver calcium — it contributes, but it is not sufficient. The dusting step is separate and non-negotiable.
For the full supplementation schedule, D3 dosing considerations, and product guidance, see our calcium and supplements guide. For MBD symptoms, what early signs look like, and when to involve a vet, see metabolic bone disease in leopard geckos.
Shedding overview
Leopard geckos shed roughly every 4–6 weeks (juveniles) and every 6–8 weeks (adults), starting at the head and working back. Pre-shed signs: dull coloring, more time in the moist hide, cloudy eyes, reduced appetite. A gecko that stops eating for a day or two before a shed is not sick.
Geckos eat their own shed skin immediately after it comes off — this is normal, not a deficiency sign. The moist hide earns its place most during shed cycles; keep it consistently damp throughout. If your gecko still has retained skin 24–48 hours after shedding started, that’s stuck shed — it needs attention before it causes damage, particularly around the toes and eye caps.
→ If you’re dealing with retained shed, see our stuck shed guide for how to help safely.
Handling and taming
Leopard geckos handle well. They’re among the most tolerant reptiles in the hobby when it comes to human contact, and that reputation is deserved — but it requires the right introduction.
When you first bring your gecko home, hold off on handling for two weeks. The gecko is adjusting to a new enclosure, new smells, and new temperature patterns — frequent handling during this window delays trust-building. Wait until you’ve seen two or three successful feedings.
Sessions of 10–15 minutes work well once you start. Approach from the side, never from above — a hand descending overhead mimics a predator strike. Scoop from underneath, support the body fully, and let the gecko move through your hands rather than restraining it. Handler tension transfers; staying relaxed actually helps.
⚠️ Never handle by the tail: Leopard geckos can voluntarily drop their tail as a defense mechanism — this is called autotomy. Under sufficient stress, or if the tail is grabbed or restrained, the tail detaches. The gecko survives, but the regenerated tail looks and feels different (smooth and rounded, without the original banded pattern) and does not fully restore the fat reserves stored in the original tail. Never hold or restrain a leopard gecko by its tail. If your gecko drops its tail, see our tail drop guide for wound care and regrowth expectations.
Reading your gecko: key body language signals
Leopard geckos communicate primarily through posture and movement. Learning to read the signals makes handling safer and helps you catch stress early:
- Slow, deliberate tail wagging: hunting mode — the gecko has spotted prey and is preparing to strike. Not a stress signal.
- Fast tail vibration (rattling): excitement or agitation. Context matters — males display this toward other males or potential mates. During handling, it can signal overarousal; set the gecko down and try again later.
- Eye closing during handling: ambiguous and context-dependent. Some geckos close their eyes when comfortable and relaxed in your hands. Others close their eyes because they’re overwhelmed and shutting out the stimulus. Watch for additional stress signals (tail vibration, escape attempts) before reading it as contentment.
- Glass surfing (pacing along enclosure walls): often a sign of hunger, stress, or a perceived enclosure issue — temperatures too high, inadequate hides, needing more space. Occasional surfing at feeding time is normal; persistent surfing is a signal to check conditions.
- Tongue flicking: normal sensory behaviour. Leopard geckos use their tongue to sample the environment — picking up chemical signals from surfaces, food, and other animals. Frequent tongue flicking while exploring is healthy and expected.
- Arched back or standing tall: defensive threat posture, most often seen when a gecko feels cornered or immediately after introduction to a new environment. Give the gecko space and time.
For the full acclimation timeline, body language signals, and technique details, see how to handle a leopard gecko. Behavioral context — what different postures and color changes mean — is covered in our leopard gecko behavior guide.
Sexing: telling male from female
Sexing is relevant if you’re planning any cohabitation (which is generally not recommended), managing a breeding project, or simply curious. Reliable visual sexing is possible from around 6–8 months; earlier than that the features are ambiguous enough to cause mistakes.
Males: Two identifiers, both at the base of the tail and underside of the body. First, the hemipenal bulges — two distinct bumps just behind the vent at the tail base, caused by the hemipenes (paired reproductive organs) stored internally. Second, femoral pores — a V-shaped row of pores along the inner thigh surface, visible as small dots arranged in a chevron pattern. In adult males these pores are pronounced and easy to see; they may be waxy or plugged. Femoral pores become reliably visible at 6–8 months.
Females: No hemipenal bulges; tail base is flat and tapered. Femoral pores are either absent or faint and undeveloped.
To check: hold the gecko gently and tilt it slightly to view the underside near the tail base. Good lighting helps — a phone flashlight pointed at the area makes the pores much easier to see. Never forcibly restrain a gecko on its back for an extended inspection.
Common health issues and vet escalation
Leopard geckos are hardy when conditions are right. Most health problems in captivity trace back to incorrect temperatures, inconsistent supplementation, or a dangerous substrate — correct those three and you eliminate most preventable problems.
Health issues overview
| Condition | Early warning signs | When to see a vet |
|---|---|---|
| Metabolic bone disease (MBD) | Soft or rubbery limbs, tremors, difficulty walking, swollen joints | At first signs — MBD progresses quickly; don’t wait |
| Impaction | Lethargy, no bowel movement for several days, visible abdominal swelling | After 3–5 days of no movement with suspected substrate ingestion |
| Cryptosporidiosis | Wasting despite eating, unexplained weight loss, regurgitation | Immediately — crypto is incurable and contagious to other reptiles; quarantine new animals |
| Respiratory infection | Open-mouth breathing, wheezing, mucus around nose or mouth | At first signs — RIs don’t resolve on their own |
| Stuck shed | Retained skin on toes, tail tip, or eye caps after 48 hours | If a 20-minute lukewarm soak doesn’t resolve it |
See a reptile specialist vet if your gecko shows any of the following:
- Soft, rubbery, or twisted limbs (MBD warning — act quickly)
- Not eating for more than 2 weeks without a clear cause such as an active shed
- Lethargy lasting more than 3 days
- Visible abdominal swelling with no bowel movement for several days (impaction flag)
- Open-mouth breathing or audible wheezing
- Discharge from eyes or nose
- A tail drop wound that is not closing or shows swelling and discoloration
- Sunken or closed eyes
Find a reptile-experienced vet before you need one. A general practice vet without regular reptile patients is not equipped to diagnose or treat most of these conditions. VCA Hospitals recommends annual wellness exams for reptiles even when they appear healthy — many conditions are detectable before symptoms develop. The Association of Reptile and Amphibian Veterinarians (ARAV) maintains a searchable directory of qualified reptile vets by location.

Brumation: the winter slowdown
Brumation is the reptile equivalent of hibernation — a period of reduced activity and metabolism triggered by seasonal changes. Wild leopard geckos experience it every winter as daylight hours shorten and temperatures drop. Many captive geckos still respond to those seasonal cues even with a fully controlled enclosure, because ambient light and household temperature fluctuations are enough to trigger the instinct.
Typical signs: reduced appetite or complete refusal to eat, spending more time in hides, lower activity in the evenings (when they’re normally most active), slower movement overall. Onset is typically fall to early winter; it usually resolves naturally by late winter or early spring.
What to do: Usually nothing. A healthy gecko entering brumation does not need force-feeding, temperature adjustments, or medical intervention. Continue offering food once a week — the gecko may decline it, and that is normal. Keep the enclosure conditions stable. Make sure fresh water is always available.
When to worry: Brumation involves low activity and reduced appetite, but not dramatic weight loss. If your gecko loses more than 10% of its body weight during this period, or if the lethargy continues for more than three months without any recovery, see a reptile vet. Prolonged lethargy outside the fall/winter period is not brumation — it’s a health flag.
Frequently asked questions
Are leopard geckos good pets for beginners?
Yes. Lower humidity requirements than most tropical reptiles, manageable adult size, a smaller enclosure footprint, and a temperament that genuinely tolerates regular handling make them one of the most accessible reptiles available. The non-negotiables — thermostat, supplementation, moist hide — aren’t complicated once you understand what they’re for. If you’re still weighing species options, the leopard gecko vs crested gecko and leopard gecko vs bearded dragon comparisons cover the key practical differences.
Do leopard geckos need UVB light?
Not strictly — leopard geckos have been kept without UVB for decades. Some reptile vets now recommend low-level UVB as a D3 synthesis support, though it’s not required for survival. If you choose to add it, a low-output T5 or T8 at a moderate distance is appropriate. See the lighting and UVB guide for full equipment guidance.
Why did my leopard gecko’s tail fall off?
Tail autotomy — the gecko dropped it as a stress response. It happens when the tail is grabbed or the gecko perceives extreme threat. The gecko survives and regrows a tail over weeks to months, but the regenerated version looks different (smooth, rounded, no original banded pattern) and doesn’t restore the original fat reserves. Not a medical emergency, but it needs monitoring. See the tail drop guide for immediate care and what to expect during regrowth.
How do I prevent metabolic bone disease (MBD)?
Consistent calcium and D3 supplementation. Dust feeders with calcium + D3 powder 2–3 times per week for adults, every feeding for juveniles. Keep a plain calcium dish in the enclosure permanently. MBD is 100% preventable with this routine — no special equipment needed, just consistency. Full supplementation schedule in the calcium and supplements guide.
Can I handle my leopard gecko every day?
Daily is possible for a well-acclimated adult, but 3–5 sessions per week gives the gecko time to decompress. Read your individual gecko’s signals — some approach the enclosure front when you open it, others tolerate handling without much enthusiasm. Both are normal. Never handle within 24 hours of feeding; skip sessions during active shed. Full technique and taming guidance in the handling guide.
How long can a leopard gecko go without eating?
A healthy adult can go 1–2 weeks without eating — especially during a shed cycle or the seasonal slowdown common in fall and winter. Past 2 weeks with no food and no obvious cause, check temperatures, look for retained shed, and check for enclosure stressors. Past 4 weeks with continued weight loss, see a reptile vet. Full diagnostic framework in the not eating guide.
Is ExoPetGuides a veterinary resource?
No. ExoPetGuides is an educational resource for keepers — it provides husbandry guidance, not medical advice. For any health concern about your gecko, the right resource is a qualified reptile veterinarian, not this website or any other care guide.
Getting started
Leopard geckos are forgiving in a lot of ways, but not in all of them. Correct temperatures, consistent supplementation, and a proper moist hide are the baseline — not upgrades you add later when you have more experience. The most common first-year mistakes: using a loose substrate before you understand the impaction risk, running a UTH without a thermostat, and treating calcium and D3 supplementation as optional. All three are straightforward to avoid with a bit of preparation before your gecko comes home.
The setup you build in the first few months is the foundation for an animal that may live 15–20 years with you. That’s worth getting right from the start.
The two most useful next reads for a new keeper are the enclosure setup guide and the diet guide. The full section has deep-dive coverage on every topic covered here.
