Leopard Gecko Care: The Complete Beginner's Guide
Leopard geckos (Eublepharis macularius) are arguably the best beginner pet lizard. They're small (8–10 inches), docile, easy to handle, available in dozens of color morphs, and live 15–20 years with proper care — sometimes 25+ years for well-kept females. They don't climb glass, don't require strong UVB historically (though current best practice includes it), and tolerate beginner-level husbandry mistakes better than most reptiles. They're also one of the few reptiles where keeping them well genuinely improves with research — there's a depth to leopard gecko husbandry that rewards engaged keepers.
Adult size and lifespan
- Adult length: 7–10 inches total
- Adult weight: 50–100 grams (males slightly smaller than females)
- Lifespan: 15–20 years typical; 25+ years possible
Enclosure
Adult leopard geckos need a minimum of 40-gallon breeder (36 in × 18 in × 16 in). Hatchlings can start in 10–20 gallon enclosures and upgrade as they grow. Front-opening reptile enclosures or glass tanks both work — leopard geckos don't climb walls, so screen-top glass tanks are fine.
Inside the enclosure:
- Three hides: warm side (90°F), cool side (75°F), and humid hide for shed
- Substrate: paper towels (quarantine), tile or slate (easy to clean), or naturalistic bioactive setup with topsoil + sand mix
- Water bowl: small, heavy, fresh dechlorinated water
- Climbing branches/rocks (optional): leopard geckos occasionally climb low rocks
Substrate considerations
Loose substrate (sand, calci-sand) carries impaction risk during feeding. Common safe options:
- Paper towels — best for hatchlings and quarantine
- Slate tile or stone — heat-conducting and impaction-safe
- Bioactive setup with cleanup crew and substrate too compact to swallow
Avoid pure sand and calcium sand — adult leopard geckos can develop impactions from accidental substrate ingestion.
Temperature gradient
- Warm side surface temperature: 88–92°F (31–33°C)
- Cool side ambient: 75–78°F
- Nighttime drop: 70–75°F
Use an under-tank heat mat covering ⅓ of the floor on the warm side, controlled by a thermostat. Heat lamps are optional — leopard geckos thermoregulate primarily by belly contact with warm substrate, not by basking.
UVB lighting
Historically considered optional for leopard geckos. Current best practice: low-level UVB benefits leopard geckos. Use a T5 HO 5.0 or 6% UVB tube on a 12-hour cycle, mounted appropriately above the cool side (so they can choose exposure). UVB improves calcium uptake, vitamin D3 production, and observed natural behavior. If using UVB, you can reduce calcium-with-D3 dusting frequency.
Humidity
Leopard geckos need 30–40% humidity ambient — drier than most pet lizards (they're desert-adapted). Provide a humid hide with damp moss for shed cycles. Sustained humidity over 50% causes scale rot.
Diet
Leopard geckos are insectivores. Recommended feeders:
- Staples: discoid roaches, crickets, BSFL
- Supplemental: small superworms, silkworms, hornworms (occasional)
- Treats only: waxworms (high fat — once monthly maximum)
- Avoid: mealworms (high fat, hard chitin — fine occasionally, not as staple)
Feeding schedule:
- Hatchlings (under 4 in): 4–6 small crickets/roaches daily
- Juveniles (4–7 in): 6–8 medium feeders every other day
- Adults (7+ in): 8–10 medium-large feeders every 2–3 days, more variety than frequency
Calcium and supplements
- Calcium with D3: dust feeders 5 days per week (if no UVB); 2–3 days per week (if UVB present)
- Multivitamin: 1× per week
- Calcium dish in enclosure: small open dish of pure calcium for self-regulation
Handling
Leopard geckos handle well — small enough to hold easily, generally calm, rarely defensive. Hatchlings can be skittish initially. Wait 24 hours after feeding before handling. Sessions 15–30 minutes are appropriate.
One quirk: leopard geckos have a body language tail twitch — slow side-to-side movements signal hunting/feeding interest, while rapid rattling signals defensive arousal. Read your gecko's tail before handling.
The fat tail — body condition indicator
Leopard geckos store fat in their tails. Tail width is the most useful body condition indicator:
- Healthy: tail width roughly equal to neck width
- Underweight: tail noticeably thinner than neck (raise feeding frequency)
- Overweight: tail substantially wider than neck (reduce feedings, use leaner feeders)
Tail loss
Leopard geckos drop their tails when stressed or grabbed. The tail regrows but is shorter, blunter, and lacks the original banding pattern. Avoid grabbing by the tail; let geckos walk onto your hand.
Color morphs
Leopard geckos have hundreds of color morphs from selective breeding:
- Wild-type: yellow with black spots
- Albino (Tremper, Bell, Rainwater): pinkish, no black pigment
- Mack snow: black-and-white instead of yellow
- Tangerine: vivid orange
- Eclipse: solid black eyes
- Enigma: striking patterns (avoid breeding pairs — neurological issues)
Morph doesn't affect care.
Health red flags
- Tail noticeably thin: weight loss; check for parasites or feeding issues
- Soft jaw, bowed legs: MBD from calcium or UVB deficiency
- Stuck shed around toes: humidity issue (provide humid hide)
- Open-mouth breathing: respiratory infection
- Refused food past 4 weeks: investigate temperature or stress
Common new-keeper mistakes
- Pure sand substrate: impaction risk. Use safer options.
- Mealworms as a staple: too much fat. Variety with leaner feeders.
- No humid hide: causes shed problems eventually.
- Holding by tail: tail drop is irreversible visually.
- Skipping calcium dusting: MBD is the most preventable leopard gecko health issue.
Bottom line
Leopard geckos are an excellent first reptile — small, docile, hardy, and forgiving. They reward keepers who research husbandry while still being suitable for first-time owners. The 15–20 year commitment is shorter than larger reptiles, making them appropriate for keepers not ready for a 25+ year species. For more on lizard husbandry, see our Creature Insights blog.
