Leopard Gecko Care Guide: Setup, Diet & Health Tips [2026]

Why Leopard Geckos Make Great Pets

Leopard geckos (Eublepharis macularius) are one of the most popular pet reptiles in the world. They are small, docile, long-lived, and come in hundreds of stunning color morphs. Unlike many geckos, they have eyelids (allowing them to "wink") and cannot climb smooth surfaces, making them easy to handle and house.

Enclosure Setup

Tank Size

• Single adult: 20-gallon long tank minimum (30x12x12 inches)
• Ideal: 40-gallon breeder tank (36x18x12 inches) — the larger, the better
• Front-opening enclosures are preferred, as top-opening tanks can trigger a predator response

Substrate

• Recommended: Solid substrate for simplicity — ceramic tile, slate, reptile carpet, or paper towels
• Advanced keepers: 70/30 organic topsoil/play sand mix (safe for adults, mimics natural environment)
• Avoid: Pure calcium sand, walnut shell, and loose substrates for juveniles (impaction risk)

Hides

Leopard geckos need three hides minimum:

1. Warm hide — on the heated side
2. Cool hide — on the unheated side
3. Moist/humid hide — lined with damp sphagnum moss or paper towel, essential for shedding

Temperature

Leopard geckos are ectothermic and need a heat gradient. Belly heat is essential for proper digestion.

Use a thermostat-controlled under-tank heater or deep heat projector. Never rely on heat lamps alone — leopard geckos need floor warmth for digestion.

Lighting

UVB (Recommended)

Modern husbandry increasingly recommends low-level UVB lighting:

• Use a shade dweller or 2-7% UVB tube light
• Place on the warm side, partially shaded by decor so the gecko can choose exposure
• 10-12 hours on, 12-14 hours off
• Replace every 6 months

Ambient Light

• A natural day/night cycle is important even without UVB
• Room lighting or a low-wattage LED on a timer works well
• Do not use colored nighttime bulbs (red or blue) — these can disturb sleep

Diet

Leopard geckos are insectivores — they eat only live insects.

Staple Insects

• Dubia roaches — Best overall feeder: high protein, low fat, low chitin
• Mealworms — Easy to keep, good staple
• Crickets — Good nutrition but noisy and can bite your gecko if left in the tank
• Black soldier fly larvae (BSFL / calciworms) — Naturally high in calcium

Treat Insects

• Waxworms — High fat, very addictive — use sparingly (1-2 per week max)
• Hornworms — Good hydration, soft body, moderate fat
• Superworms — High fat, harder chitin — occasional treat only

Feeding Schedule

Supplementation

• Calcium without D3: Dust every feeding; also keep a small dish of calcium powder in the enclosure
• Calcium with D3: Dust once a week (twice if no UVB provided)
• Multivitamin: Dust once every 1-2 weeks

Shedding

Leopard geckos shed their entire skin in one piece and eat it (this is normal — it recycles nutrients).

• Babies: Shed every 1-2 weeks
• Juveniles: Every 2-3 weeks
• Adults: Every 4-6 weeks

Helping with Shed

• Maintain the moist hide with damp sphagnum moss at all times
• If shed is stuck (especially on toes or tail tip), soak in lukewarm water for 15-20 minutes and gently remove with a damp cotton swab
• Stuck toe shed can cut off circulation and cause toe loss — check toes after every shed

Handling

Leopard geckos are one of the most handleable reptiles:

• Wait one week after bringing your gecko home before handling
• Start with 5-minute sessions and work up to 15-20 minutes
• Scoop from below — never grab from above
• Let them walk across your hands rather than restraining them
• Never grab the tail — they can drop it as a defense mechanism
• Handle over a soft surface (bed, couch) in case they jump

Common Health Issues

Metabolic Bone Disease (MBD)

The most common health problem in leopard geckos. Caused by calcium and/or vitamin D3 deficiency.

Signs: wobbly walking, soft/flexible jaw, tremors, difficulty catching prey, curved spine.

Prevention: proper supplementation, UVB lighting, gut-loaded feeder insects.

Impaction

Intestinal blockage from swallowing substrate or oversized prey. Signs include loss of appetite, bloating, and inability to defecate.

Prevention: use solid substrate (tile, paper towel), feed appropriately-sized insects, maintain proper warm-side temperatures.

Stuck Shed

Especially dangerous on toes where constricting bands of shed can cut off blood flow.

Prevention: always maintain a humid hide, check toes after each shed.

Cryptosporidiosis (Crypto)

A parasitic infection that causes chronic weight loss, stick tail (emaciated tail base), and regurgitation. Unfortunately, there is no reliable cure. Quarantine new geckos for 90 days before introducing them near other reptiles.

Conclusion

Leopard geckos are exceptional pets — calm, hardy, long-lived, and strikingly beautiful. Focus on getting the essentials right: proper heat gradient with a thermostat, three hides (warm, cool, moist), a diet of gut-loaded and supplemented insects, and low-level UVB. With these fundamentals in place, your leopard gecko can be a companion for 15-20+ years.
