Leopard Gecko Care: The Complete Setup and Husbandry Guide

The Perfect Starter Lizard

Leopard Geckos (Eublepharis macularius) have been captive-bred for decades, come in stunning morphs, have genuine personalities, and are one of the hardiest reptiles in the hobby. They're small, don't need special lighting (though it helps), and eat insects every few days. But "easy" is relative — they still need correct temperatures, proper supplementation, and an enclosure that meets their needs.

Enclosure

A single adult Leopard Gecko needs a minimum 40-gallon (36" x 18" x 18") front-opening terrarium. The Exo Terra 36x18x18 Glass Terrarium is a popular choice with front-opening doors that make access easy and reduce the "predator from above" stress response.

Floor space matters more than height. Leopard Geckos are terrestrial — they live on the ground, not in trees. A longer, shallower enclosure is better than a tall one. That said, they do appreciate low climbing opportunities like cork bark flats and stone ledges.

20-gallon tanks are the old recommendation and too small for an adult. They can work temporarily for juveniles, but plan to upgrade.

Heating

Leopard Geckos are crepuscular (active at dawn and dusk) and thermoregulate using belly heat absorbed from sun-warmed rocks in the wild. They need a warm side and a cool side.

• Warm side floor temperature: 88-92°F
• Cool side: 72-77°F
• Night: Can drop to 65-70°F

The best heating method is an overhead halogen or deep heat projector directed at one side, creating a natural heat gradient. This is more natural than under-tank heat mats and heats the air as well as surfaces.

If using a heat mat, it must be on a thermostat. Unregulated heat mats reach temperatures that cause severe thermal burns through the glass floor. The Inkbird ITC-308 is the standard recommendation.

Use an infrared temperature gun to measure surface temperatures accurately. The stick-on thermometers are unreliable.

Lighting and UVB

Leopard Geckos can survive without UVB if you supplement with vitamin D3. However, providing low-level UVB (2-5% shade dweller) allows them to self-regulate their own D3 synthesis, which is healthier and more natural. The Arcadia ShadeDweller ProT5 is designed specifically for crepuscular species like Leopard Geckos.

Even without UVB, provide a light cycle. A simple LED or room lighting on a 12-hour schedule gives them a proper day/night rhythm.

Do NOT use colored bulbs (red, blue, purple). Leopard Geckos can see these wavelengths, and they disrupt the natural photoperiod.

Substrate

This is one of the most debated topics in Leo keeping. Here's the straightforward answer:

For juveniles (under 6 months): Paper towels or textured tile. Young Leos are clumsy hunters and impaction risk is real when they miss their target and grab a mouthful of substrate.

For healthy adults with correct temperatures: A 70/30 mix of organic topsoil and play sand, or textured ceramic/slate tile. The soil-sand mix allows natural digging behavior and is safe for adults whose digestive systems function properly at correct temperatures. Cold Leopard Geckos can't digest incidentally ingested substrate — that's where impaction happens.

Avoid: Calcium sand (marketed as "digestible" — it's not), reptile carpet (catches toenails and harbors bacteria), walnut shell, and wood chips.

Diet

Leopard Geckos are strict insectivores. No fruits, no vegetables, no prepared diets.

Staple feeders:

• Dubia roaches — the best option: high protein, low fat, no odor, can't infest your house
• Crickets — work fine but stink and escape
• Black soldier fly larvae (Nutrigrubs) — excellent calcium-to-phosphorus ratio

Treat feeders (once or twice a week max):

• Mealworms — moderate fat, fine as an occasional staple
• Waxworms — high fat, addictive, use sparingly
• Hornworms — hydrating and nutritious, but expensive

Feeding schedule:

• Juveniles: Daily, as many as they'll eat in 10-15 minutes
• Adults: Every other day, 5-7 appropriately sized insects

Supplementation is critical:

• Dust with plain calcium at every feeding
• Dust with calcium + D3 once a week (twice if no UVB)
• Dust with a multivitamin once a week
• Keep a small dish of plain calcium powder in the enclosure — Leos will lick it when they need extra

Without proper supplementation, Leopard Geckos develop MBD regardless of how well you feed them. The insects alone don't contain enough calcium.

Hides

Leopard Geckos need three hides minimum:

1. Warm hide — on the heated side
2. Cool hide — on the unheated side
3. Humid/moist hide — lined with damp sphagnum moss or paper towel, placed on the warm side

The humid hide is essential for healthy shedding. Without it, Leos get stuck shed on their toes, which constricts circulation and can cause toe loss. Check the humid hide every few days and remoisten as needed.

Handling

Leopard Geckos tolerate handling well once tamed. Start with short sessions (5 minutes), scoop from below, and never grab from above or by the tail. Their tails detach as a defense mechanism — it grows back, but the regenerated tail looks different and it's stressful for the animal.

Most Leos become genuinely comfortable with their owners within a few weeks of consistent, gentle handling.

Lifespan

Leopard Geckos live 15-20+ years with proper care. The oldest recorded was over 28. This is not a short-term pet — plan accordingly.
