Leopard Gecko Care: The Complete Beginner's Guide

Leopard geckos (Eublepharis macularius) are, in my opinion, the best beginner pet lizard there is. They're small (8–10 inches), docile, easy to handle, available in dozens of color morphs, and they live 15–20 years with good care — sometimes 25+ for well-kept females. They don't climb glass, they were historically kept without strong UVB (though current best practice includes it), and they forgive beginner-level mistakes better than almost any other reptile. They're also one of the few reptiles where keeping them genuinely gets better the more you learn — there's real depth here that rewards an engaged keeper while still being friendly to a first-timer.

Here's everything you need to keep one well.

Adult size and lifespan

• ◆Adult length: 7–10 inches total
• ◆Adult weight: 50–100 grams (males run slightly smaller than females)
• ◆Lifespan: 15–20 years typical; 25+ years possible

That 15–20 year commitment is shorter than larger reptiles, which makes leopard geckos a good fit for keepers who aren't ready for a 25-plus-year species but still want a long-term companion.

Enclosure

An adult leopard gecko needs a minimum 40-gallon breeder (36 × 18 × 16 inches). Hatchlings can start in a 10–20 gallon and upgrade as they grow. Because leos don't climb walls, a screen-top glass tank or a front-opening reptile enclosure both work fine — and floor space matters more than height for this ground-dweller.

Inside the enclosure:

• ◆Three hides — a warm hide (over the heated zone), a cool hide (cool side), and a humid hide with damp moss for shedding. The humid hide is the one beginners skip and regret.
• ◆Substrate — paper towels (quarantine and hatchlings), tile or slate (easy to clean, impaction-safe), or a naturalistic bioactive setup with a topsoil/sand mix that's too compact to swallow.
• ◆Water bowl — small, heavy, with fresh dechlorinated water.
• ◆Climbing rocks (optional) — leos will clamber over low rocks now and then.

A word on substrate safety

Loose substrate is the classic leopard gecko hazard. Avoid pure sand and calcium ("calci") sand — adults can develop impactions (gut blockages) from accidentally ingesting it while feeding. Stick with paper towels, slate or stone tile, or a properly built bioactive substrate. The MSD/Merck Veterinary Manual is a solid neutral reference on impaction and reptile husbandry.

Temperature gradient

Leopard geckos thermoregulate primarily by belly contact with warm ground, not by basking, so the heat setup is different from a dragon's:

• ◆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 about ⅓ of the floor on the warm side, run through a thermostat. A heat lamp is optional. Always verify temperatures with a digital thermometer — a cold gecko stops eating, and appetite loss almost always traces back to temperature first.

UVB lighting

UVB was long considered optional for leopard geckos, but the current best practice is clear: low-level UVB benefits them. Use a T5 HO 5.0 (6%) tube on a 12-hour cycle, mounted over the cool side so the gecko can choose its exposure. UVB improves calcium uptake, supports vitamin D3 production, and encourages more natural behavior. If you run UVB, you can scale back calcium-with-D3 dusting frequency (more on that below).

Humidity

Leopard geckos are desert-adapted and want it drier than most pet lizards: 30–40% ambient humidity. Provide the humid hide with damp moss for shed cycles, but keep the general enclosure on the dry side — sustained humidity over 50% can cause scale rot.

Diet

Leopard geckos are strict insectivores — they never eat vegetables to fill nutritional gaps, which makes feeder quality and variety especially important.

• ◆Staples: discoid roaches, crickets, black soldier fly larvae
• ◆Supplemental: small superworms, silkworms, hornworms (occasional)
• ◆Treats only: waxworms (high fat — once a month maximum)
• ◆Avoid as a staple: mealworms (high fat, hard chitin — fine occasionally, not as a base)

Feeding schedule:

• ◆Hatchlings (under 4 in): 4–6 small crickets or roaches daily
• ◆Juveniles (4–7 in): 6–8 medium feeders every other day
• ◆Adults (7+ in): 8–10 medium-to-large feeders every 2–3 days — favor more variety over more frequency

Discoid roaches make an excellent staple: high protein, soft-bodied, no climbing, no biting, and they gut-load well. All Angles Creatures stocks discoid roaches in the right sizes, and my feeder-sizing guide covers the "no wider than the space between the eyes" rule that keeps every meal safe. If your leo gets stuck on one feeder and refuses others, silkworms are the best tool for breaking a fixation.

Calcium and supplements

This is the single most important thing for long-term health, because metabolic bone disease (MBD) is the most preventable problem leopard geckos face:

• ◆Calcium with D3: dust feeders 5 days a week if you're not using UVB; 2–3 days a week if you are.
• ◆Multivitamin: once a week.
• ◆Calcium dish: keep a small open dish of plain calcium in the enclosure for self-regulation.

Handling

Leopard geckos handle well — small enough to hold easily, generally calm, rarely defensive. Hatchlings can be skittish at first. Wait 24 hours after feeding before handling, and keep sessions to 15–30 minutes.

One useful quirk: leos talk with their tails. Slow side-to-side movements signal hunting or feeding interest; a rapid rattle signals defensive arousal. Read the tail before you reach in.

The fat tail — your body-condition gauge

Leopard geckos store fat in their tails, which makes tail width the most useful health indicator you have:

• ◆Healthy: tail width roughly equal to neck width
• ◆Underweight: tail noticeably thinner than the neck — raise feeding frequency
• ◆Overweight: tail much wider than the neck — reduce feedings and switch to leaner feeders

Tail loss

Leos drop their tails when stressed or grabbed. The tail regrows, but shorter, blunter, and without the original banding. Never grab by the tail — let the gecko walk onto your hand.

Shedding

Leopard geckos shed regularly — every couple of weeks as fast-growing juveniles, less often as adults. A few days before a shed the skin turns dull, milky, or grayish, and appetite often dips (which is normal — don't mistake a pre-shed fast for illness). The humid hide is what makes a clean shed possible: the gecko sits in the damp moss to soften the old skin, then works it off in one piece, and often eats it. The spot to watch is the toes — retained shed there can tighten like a band and, over repeated cycles, cost a gecko a toe. If you see stuck shed on the toes, raise humidity, make sure the humid hide is genuinely damp, and gently assist with a warm cotton swab if needed. Never peel shed that isn't ready to come off.

Can leopard geckos live together?

Short answer: keep them solo. Leopard geckos are not social animals — they tolerate solitude perfectly well and "company" only adds risk. Two males will fight, sometimes to serious injury. A male and female housed together breeds the female relentlessly, which is hard on her body. Even two females can bully each other, with a dominant animal monopolizing the warm hide and food while the subordinate slowly declines — often without obvious fighting, just one gecko quietly losing weight. One gecko per enclosure is the simplest way to avoid all of it.

Color morphs

Selective breeding has produced hundreds of morphs: wild-type (yellow with black spots), albino lines (Tremper, Bell, Rainwater — pinkish, no black pigment), Mack snow (black-and-white instead of yellow), tangerine (vivid orange), eclipse (solid black eyes), and enigma (striking patterns — but avoid breeding enigma pairs due to neurological issues). Morph doesn't change care.

Health red flags

• ◆Tail noticeably thin: weight loss — check for parasites or feeding problems
• ◆Soft jaw, bowed legs: MBD from calcium or UVB deficiency
• ◆Stuck shed around the toes: humidity issue — provide the humid hide
• ◆Open-mouth breathing: possible respiratory infection
• ◆Refused food past 4 weeks: investigate temperature or stress first

Common new-keeper mistakes

• ◆Pure sand substrate — impaction risk; use a safer option.
• ◆Mealworms as a staple — too much fat; rotate leaner feeders.
• ◆No humid hide — leads to shedding problems eventually.
• ◆Holding by the tail — tail drop is visually permanent.
• ◆Skipping calcium dusting — MBD is the most preventable health problem there is.

Bottom line

Leopard geckos are an excellent first reptile — small, docile, hardy, and forgiving — that still reward keepers who care to learn. Nail the temperature gradient, add low-level UVB, keep humidity low with a humid hide for sheds, feed a varied insect diet built on discoid roaches, and stay on top of calcium. Do that and you'll have a healthy gecko for 15–20 years.
