Facts

Full fact guide →

Leopard gecko facts, myths, and biology explained individually.

Leopard geckos are crepuscular, not nocturnal The tail stores fat reserves, not water Dropped tails grow back, but never look the same Leopard geckos cannot climb glass — they have claws, not sticky lamellae Leopard geckos can blink — most gecko species cannot You can see through a leopard gecko's head via the ear canals Sex is determined by incubation temperature, not genetics Eating shed skin is normal — not a sign of nutritional deficiency Metabolic Bone Disease is entirely preventable and is the most common serious condition in captive leos Leopard geckos live 15–20 years in captivity — some males exceed 25 years Cryptosporidiosis is incurable and fatal — quarantine all new geckos for 90 days minimum Loose particle substrates including calcium sand can cause fatal gut impaction A proper thermal gradient is not optional — belly heat matters more than air temperature Low-level UVB improves health even though leos were kept without it for decades Slow tail wave means hunting — fast tail rattle means threat or stress Glass surfing is a husbandry warning sign, not normal settled behaviour Reduced appetite in winter is normal brumation behaviour — not illness Leopard geckos are native to the rocky arid grasslands of Afghanistan, Pakistan, Iran, and northwest India Hatchlings show bold black-and-white banding that breaks up into spots as they mature A single female can lay up to 8–10 clutches of two eggs in one breeding season Females can develop dystocia (egg binding) even without ever being mated The pale bulges visible behind a leopard gecko's jaw are calcium storage sacs, not swelling or illness Adult males have a visible row of preanal pores that females lack or show only faintly Leopard geckos are poor swimmers and can drown in deep water Grabbing or restraining a leopard gecko by the tail is the single most common cause of accidental tail loss in handling Leopard geckos can darken their skin colour in response to cold, stress, or low light Leopard geckos continuously replace their teeth throughout life A leopard gecko bite feels like a pinch and rarely breaks skin Leopard geckos are completely non-venomous A dropped tail typically takes 30–60 days to regrow to a usable length A leopard gecko can drop and regrow its tail more than once in its lifetime A humid hide is essential for clean sheds, particularly around the toes and tail tip Retained shed on the toes can cut off circulation and cause a toe to die and fall off if left untreated Repeated glass surfing can wear away the scales on the nose, causing sores that are prone to infection The white portion of a leopard gecko's droppings is urate, and its consistency is a useful hydration indicator Feeder crickets should be gut-loaded for at least 24 hours before being fed to a gecko Mealworms have a thicker chitin exoskeleton that makes them harder to digest, especially for juveniles Superworms have strong mandibles that can bite a gecko if left loose in the enclosure overnight Waxworms are extremely high in fat and should only be fed as an occasional treat Dubia roaches are considered one of the most nutritionally balanced staple feeders for leopard geckos Leopard geckos get a meaningful portion of their hydration from the moisture content of their prey Adult male leopard geckos will fight if housed together and should never share an enclosure Visual sexing of leopard geckos becomes reliable at around 6 months of age, not before Leopard gecko eggs typically incubate for 35–89 days depending on temperature Leopard gecko hatchlings emerge at roughly 2.5–3 inches long and weigh only a few grams Leopard geckos generally reach full adult size by around 18–24 months of age Even though leopard geckos can't climb glass, a secure lid is still necessary because they can push against loosely fitted screen tops Wild leopard geckos dig and use burrows for shelter, and captive geckos benefit from substrate deep enough to dig in Leopard geckos flick their tongues to sample scent particles using a specialised organ in the roof of the mouth A stressed or startled leopard gecko may hiss as a defensive warning New leopard gecko keepers should generally wait until a gecko settles into its enclosure — commonly a week or more — before starting regular handling Juvenile leopard geckos are typically fed daily, while adults are commonly fed every other day Sexual maturity in leopard geckos is better judged by body weight than age alone New leopard geckos should be quarantined in a separate room from other reptiles for a minimum of 60–90 days A fecal exam from an exotics vet is the most reliable way to detect internal parasites in a leopard gecko A gravid female needs a dedicated lay box with moist substrate to lay her eggs safely For decades leopard geckos were successfully kept and bred without any UVB lighting at all Leopard geckos should get vitamin A from beta-carotene sources or a balanced multivitamin rather than high-dose preformed vitamin A Tail thickness is one of the most reliable at-a-glance indicators of a leopard gecko's body condition Slate or ceramic tile is a popular substrate choice because it carries zero impaction risk and holds heat well In addition to true eyelids, leopard geckos have a thin nictitating membrane that helps keep the eye moist and clean Leopard geckos can produce audible squeaks or chirps, usually when startled or handled roughly Regularly weighing a leopard gecko on a gram scale is one of the easiest ways to catch health problems early Juvenile leopard geckos shed roughly every 1–2 weeks, while adults shed about once a month Leopard geckos should never be housed with other reptile species, even other gecko species Leopard geckos are not listed under CITES and are assessed by the IUCN as a species of least concern Belly heat from below is more important to a leopard gecko than overhead ambient warmth Leopard geckos belong to Eublepharidae, the "eyelid geckos" family Vertical, elliptical pupils let a leopard gecko's eyes open extremely wide in darkness Research suggests leopard geckos can distinguish colours even in near-total darkness Leopard gecko skin is covered in small bumps called tubercles, not smooth scales Leopard gecko teeth are pleurodont, attached along the inner side of the jawbone Adult leopard geckos typically reach 7-10 inches long and weigh 45-90 grams A consistent light/dark cycle on a timer helps regulate a leopard gecko's natural rhythm The "three hide rule" gives a leopard gecko a warm hide, a cool hide, and a humid hide A shallow water dish should be cleaned and refreshed at least every couple of days Floor space matters more than height for a leopard gecko's enclosure Paper towel is a common starter substrate recommended to new keepers Enclosure decor for a leopard gecko is mostly about ground-level features, not height A heating thermostat's probe should sit on the warm-side floor, not on the heat source itself Under-tank heat mats and overhead ceramic heat emitters are the two most common leopard gecko heat sources Daily spot-cleaning of waste keeps bacterial buildup down between full substrate changes Juveniles are sometimes started in a smaller, simpler enclosure before moving to full adult housing Bioactive leopard gecko setups use isopods and springtails to help break down waste Rotating hide positions and adding new textures counts as meaningful enrichment Heat sources used without a thermostat are a leading cause of severe burns in captive geckos Paper towel is the standard substrate for a quarantine or hospital setup Persistent retained shed despite a humid hide can signal an underlying issue Wheezing, mucus, or open-mouth breathing can indicate a respiratory infection Swelling or discharge around the mouth can indicate infectious stomatitis, known as mouth rot Retained shed around the eyes can trap debris and cause irritation Weight loss despite a normal appetite can point to internal parasites Noticeable weight loss over a couple of weeks is one of the most reliable early illness signs Any tissue protruding from the vent is a veterinary emergency Panting and restlessness can signal an enclosure is too hot Slow-to-spring-back skin after a gentle pinch can suggest dehydration An annual wellness exam helps catch subclinical health issues early Males often grip a female's neck or flank gently during courtship Leopard gecko mating typically lasts only a few minutes at a time Each leopard gecko clutch normally contains exactly two eggs A well-conditioned female can lay 15-20 or more eggs across one breeding season Female leopard geckos can store sperm from a single mating for later clutches Leopard gecko eggs have a soft, leathery shell rather than a hard, calcified one Eggs are commonly incubated in slightly moist vermiculite or perlite Candling with a bright light can reveal whether an egg is developing Stable incubation temperature matters as much as the exact value chosen Many breeders give adults a winter cooling period to help trigger breeding season Females can produce several clutches only weeks apart within the same season Siblings from the same clutch can occasionally hatch as different sexes Leopard geckos lick surfaces and their own eyes to gather scent information Partial burrowing in loose substrate is a normal thermoregulatory and security behaviour Some geckos learn to associate a keeper's presence with feeding time Body flattening or standing tall on extended legs can be a size display between geckos Extended hiding after a move to a new enclosure is a normal adjustment response The quick lunge-and-grab feeding strike is a fixed hunting reflex Leopard geckos typically sleep with their eyes closed, tucked in a hide Geckos may rub or drag their vent area on surfaces to leave scent marks The species name Eublepharis macularius comes from Greek and Latin words meaning 'true eyelid' and 'spotted'Female leopard geckos can store viable sperm for several months and lay multiple fertile clutches from a single mating Leopard geckos almost always lay exactly two eggs per clutch, occasionally one Leopard gecko eggs have a soft, leathery parchment-like shell rather than a hard, brittle one Adult male leopard geckos have a row of preanal pores, not femoral pores running down the thighs Leopard geckos lack an extendable throat dewlap used by some other lizards for display Keeping a consistent roughly 12-hour light and 12-hour dark cycle helps regulate a leopard gecko's natural crepuscular rhythm, even without UVB Leopard geckos are ambush predators that strike sideways at prey rather than chasing it down over distance Leopard geckos were among the first gecko species bred in captivity at scale, starting in the 1970s-80s pet trade Leopard geckos have poor tolerance for prolonged cold and can become seriously ill or die if enclosure temperatures drop and stay low for extended periods Brumation is not required for a pet leopard gecko's health and is mainly used deliberately by breeders to help cycle animals for reproduction Leopard geckos often show strong site fidelity, repeatedly returning to the same preferred hide rather than rotating between them Leopard gecko skin lacks the bony osteoderm plates found in the skin of some other lizard groups Very pale morphs such as blizzards and some albino lines can be more sensitive to bright light than wild-type coloured geckos Leopard geckos primarily get drinking water from a shallow dish rather than relying on misted droplets like some arboreal gecko species A leopard gecko's digestion slows dramatically or stalls if its body temperature is too low after eating Leopard geckos cannot reproduce asexually — unlike a small number of other gecko species, they always require a male for fertile eggs Female leopard geckos cycle and produce eggs on a seasonal basis even in captivity, driven partly by day length and temperature cues Paired hemipenal bulges at the base of the tail are one of the clearest visual sexing cues in mature male leopard geckos Leopard geckos can regenerate a lost tail but cannot regenerate a lost limb or toe Leopard geckos do not have cheek pouches for storing food, unlike some other animals — prey is swallowed shortly after capture Most leopard gecko setups rely on under-tank belly heat rather than an overhead basking bulb as the primary heat source Leopard geckos typically shed their skin in several large pieces rather than one continuous sheet Bone growth in leopard geckos slows significantly once they reach roughly two years of age, coinciding with reaching adult size Leopard gecko colour darkening is a temperature and stress response, not an active camouflage mechanism used to match surroundings Leopard geckos often key in on movement and vibration from prey rather than relying primarily on sight to detect food A regrown tail is generally shorter and stores fat less efficiently than the original, so body condition should be judged with this in mind on geckos that have dropped a tail A single adult leopard gecko is commonly recommended a minimum floor space in the range of a 20-gallon long equivalent, with larger being better Leopard geckos are frequently mislabelled as strictly nocturnal, when they are more accurately described as crepuscular Colour and pattern in leopard geckos are controlled by separate, sometimes independently inherited genetic traits Faint stress marks or blotchiness that appear during illness, shipping, or handling in a healthy gecko usually fade once the stressor is resolved Spot-cleaning waste daily and doing a full substrate and decor clean on a regular schedule reduces bacterial and parasite buildup Short, calm handling sessions are generally better tolerated than long ones, especially for newer or more skittish geckos Leopard geckos may drag their vent area across surfaces to deposit scent, particularly noticeable in enclosures housing more than one animal A breeding female can lay several clutches across a single season, spaced roughly two to four weeks apart Not every veterinarian treats reptiles, so finding an exotics or reptile-experienced vet before an emergency arises is strongly recommended A temporary drop in appetite is common in the day or two immediately before a visible shed begins If UVB lighting is used, the distance between the bulb and the gecko's basking area significantly affects the actual UV dose received Any heat source used for a leopard gecko should be controlled by a thermostat rather than run directly off a wall outlet Changes in stool consistency, colour, or frequency over time are one of the earliest visible signs keepers can use to flag a potential health issue Juvenile leopard geckos are generally best housed individually rather than grouped, since even same-age juveniles can compete over food and space Modern UVB guidance for leopard geckos is often expressed as a target UV Index range for the basking zone rather than a bulb wattage alone UVB bulbs lose effective output over time even if they still produce visible light, and are generally recommended for replacement roughly every 6-12 months Rapid tail thinning over a short period, rather than a gradually slender tail, is a stronger warning sign of acute illness or parasite load Impaction risk from loose substrates scales with how finely particulate the material is, with very fine sand-like particles generally considered higher risk than larger particle substrates Enrichment such as varied textures, safe climbing branches, and occasional layout changes can encourage more natural exploratory behaviour Many keepers weigh their leopard gecko roughly weekly to monthly on a gram scale to build a baseline weight trend over time Infertile 'slug' eggs from an unmated or unsuccessfully mated female are a normal outcome and not a sign of illness on their own Many keepers wait a short period after feeding, often at least 24-48 hours, before handling to reduce the risk of regurgitation A digital infrared thermometer or probe thermometer gives a far more reliable temperature reading than judging warmth by hand or relying solely on a stick-on analog dial The species was formally described by zoologist Edward Blyth in 1854 Wild leopard geckos are grouped into several recognised regional subspecies across their range Leopard geckos have no visible parietal ('third') eye on top of the head Hatchlings use a temporary egg tooth to cut their way out of the shell Wild leopard geckos will prey on scorpions and other small geckos, not just insects The visible ear opening (tympanum) sits just behind the jaw and leads to a functional middle ear Leopard geckos behaviourally regulate toward a fairly narrow preferred body temperature when given a full thermal gradient In the wild, leopard geckos brumate underground through the coldest winter months A well-conditioned leopard gecko can survive several weeks without food by drawing on tail and abdominal fat reserves Genetic tests are commercially available to confirm certain leopard gecko morph traits, such as Eclipse or specific albino lines Leopard gecko hearing is most sensitive to relatively low-frequency sounds rather than a broad high-frequency range The waxy secretion produced by a mature male's preanal pores is used for territorial scent-marking, not just visual sexing Rotating between two or more feeder insect species helps prevent nutritional deficiencies that can develop from an exclusively single-prey diet Some leopard geckos develop a strong preference for one feeder insect and may refuse others for a period A cold, sluggish leopard gecko should be warmed up gradually rather than handled normally Leopard gecko eyes are adapted for low-light vision through a retina dominated by rod-like photoreceptors Wild leopard gecko populations are assessed by the IUCN as Least Concern, though localised habitat pressures exist Leopard geckos can shift slightly darker or lighter as part of behavioural thermoregulation, not only as a stress response Leopard geckos have no venom or toxin-producing glands of any kind A healthy adult leopard gecko typically passes a formed stool roughly every one to three days depending on feeding frequency and temperature Leopard geckos are used as a research model species in regeneration and reproductive biology studies Leopard gecko enclosure design should prioritise usable floor-level features over vertical height, unlike arboreal gecko species Steep, unstable rock or decor arrangements pose a fall and crush-injury risk and should always be secured Quarantine protocols call for entirely separate tools, hides, and dishes for a new gecko, not just physical distance from other reptiles A UVB fixture should only cover part of a leopard gecko enclosure, leaving a shaded zone so the gecko can self-regulate exposure A bioactive or naturalistic leopard gecko substrate is typically built several inches deep to support natural digging behaviour Skin often looks slightly duller or greyish in the day or two before a shed begins Leopard gecko eggs are commonly incubated in a dedicated incubator rather than left at ambient room temperature At the cooler end of the viable incubation range, eggs can take upward of 80-90 days to hatch A female typically resumes normal appetite within a day or two of laying a clutch Males often vibrate or shake their tail rapidly during courtship approaches to a female A receptive female's body language during introduction differs noticeably from a female actively rejecting a male's advances Incubation humidity is managed separately from incubation temperature, and both need to be correct for healthy hatch rates Lipid layers in gecko skin help reduce water loss in an arid habitat Shedding frequency gradually decreases as a leopard gecko ages past its rapid juvenile growth phase Placing hides in enclosure corners, rather than the centre, generally makes a gecko feel more secure A bioactive leopard gecko setup can maintain a slightly more humid microclimate at substrate level than a bare-bottom tile enclosure Visible fat rolls along the sides and an overly bulbous tail base beyond normal fullness can indicate obesity rather than good body condition Changing enclosure substrate or major decor layout can cause temporary hiding or reduced appetite as a gecko reorients itself Leopard geckos are one of relatively few gecko species that have true, moveable eyelids Leopard gecko squeaks and chirps are produced by forcing air through the throat and mouth rather than by true vocal cords The eyelid gecko family Eublepharidae includes several genera beyond Eublepharis, such as the African fat-tailed geckos A leopard gecko enclosure benefits from a humidity gradient, not just one uniform ambient reading Many keepers retrofit UVB lighting into enclosures originally set up without it, rather than only planning it from the start Leopard gecko colour change is limited to darkening and lightening along their existing pattern, not shifting to different hues Tolerance for frequent handling varies considerably between individual geckos, independent of morph or sex A heavier ceramic water dish is less likely to be tipped or dragged around than a lightweight plastic one Minor skin injuries in leopard geckos typically heal without permanent scarring, aided by their regular shedding cycle An overhead basking bulb, when used, generally plays a secondary role to under-tank belly heat rather than the primary heat source Leopard geckos were among the first gecko species bred in captivity at scale, beginning in the pet trade of the 1970s and 1980s Leopard geckos rarely need to lick their eyes clean because their movable eyelids do the job Three distinct albino leopard gecko lines exist — Tremper, Rainwater, and Bell — and they are not genetically interchangeable The Enigma morph is linked to a neurological condition called Enigma syndrome Leopard gecko morphs are inherited as recessive, dominant, or incompletely dominant/co-dominant traits depending on the specific gene Leopard geckos have five toes on each foot, each tipped with a small curved claw Many leopard geckos eat noticeably less in the 24-48 hours before a visible shed Rotating between two or more feeder insect species reduces the risk of a single nutrient deficiency Even female-only leopard gecko groups can develop feeding-time competition and subtle bullying Leopard geckos can produce an audible squeak or bark when startled or roughly handled Some captive leopard geckos have documented lifespans well past 25 years, with a handful of reported cases approaching 30 When UVB is provided for leopard geckos, a low-output T5 5% or similar linear tube is the commonly recommended option Incubating containers need ventilation holes even though the eggs require constant humidity Developing eggs are often visible as pale oval shapes through a gravid female's abdomen A female commonly rests and eats less for a day or two immediately after laying a clutch Surface substrate temperature above a heat mat can run several degrees hotter than the air temperature nearby Tail autotomy in leopard geckos occurs along specific fracture points within the tail vertebrae, not at a random break point Leopard geckos are one of the few common pet gecko species without a fixed transparent brille covering the eye Leopard gecko hatchlings absorb their remaining yolk sac in the first few days and don't need feeding immediately Keepers using UVB lighting sometimes switch to calcium powder without added vitamin D3 for regular dusting Loose crickets left in the enclosure overnight can nibble on a sleeping or unwell gecko Body condition in leopard geckos is best judged by combining tail thickness, hip/pelvis visibility, and overall weight rather than any single measure Checking the tail tip and toes right after a shed is completed catches most cases of retained skin before they become a problem Switching a leopard gecko to a new substrate is usually done gradually rather than all at once Prolonged contact with damp, dirty substrate can cause a bacterial skin condition sometimes called scale rot Red or blue 'night bulbs' are not necessary for leopard geckos and are increasingly discouraged A pet leopard gecko not intended for breeding does not need to be brumated Keepers in areas prone to power outages sometimes keep a battery-powered backup heat option or an emergency plan for cold snaps Wild-type leopard geckos vary noticeably in base color and spot pattern even without any named morph genetics involved Juvenile leopard geckos are typically offered food sized no larger than the width of their head, offered until they stop actively hunting Male leopard geckos have small pre-anal pores that secrete a waxy substance used partly for scent marking A veterinary X-ray is the most reliable way to confirm the extent of bone changes from Metabolic Bone Disease Quarantined leopard geckos should have entirely separate feeding tongs, water dishes, and cleaning tools from the rest of a collection A gecko's colors often look dull, pale, or slightly bluish-grey in the day or two before shedding Leopard gecko embryos develop using nutrients from a yolk sac inside the leathery egg rather than any parental feeding Housing leopard geckos with other reptile or amphibian species increases the risk of introducing pathogens the leopard gecko has no natural resistance to Transport stress after purchase can suppress appetite for several days even in an otherwise healthy leopard gecko Tail movement in leopard geckos communicates different things depending on speed and posture A well-established bioactive substrate can help buffer minor humidity swings compared with bare solid flooring Even a mainly crepuscular leopard gecko may bask briefly near a warm hide during the day Plain dechlorinated or filtered tap water is generally sufficient for a leopard gecko's water dish Scheduling an initial veterinary check within the first few weeks of ownership helps establish a baseline for a new leopard gecko Approaching a leopard gecko from the side rather than directly overhead tends to startle it less Cedar and untreated pine shavings are avoided as leopard gecko substrate due to aromatic oils that can irritate the respiratory system and skin Providing more than one warm-side hide can reduce competition-driven stress in enclosures housing more than one gecko Some studies and clinical observations suggest leopard geckos provided with appropriate low-level UVB show improved bone density markers over time Many leopard geckos can be trained to reliably take food from feeding tongs rather than only from a dish A modest nighttime temperature drop of a few degrees is generally acceptable and mimics natural daily fluctuation Loose particulate substrates used in an established bioactive setup carry a different impaction risk profile than plain loose sand alone Keeping a simple ongoing weight log, not just a one-off weigh-in, makes small downward trends far easier to catch Leopard geckos are sometimes confused with the related, less commonly kept fat-tailed gecko, Hemitheconyx caudicinctus
