🏗️ Enclosure & Habitat Structure
Leopard Geckos (Eublepharis macularius) are terrestrial geckos. While they don't have sticky toe pads, they are active explorers that require ample floor space.
Minimum Enclosure Dimensions:
- Juveniles: 20 Gallon Long (30" x 12" x 12").
- Adults (Modern Standard): 40 Gallon Breeder (36" x 18" x 18") is the minimum recommended for an adult to thrive.
A "Three-Hide Minimum" is mandatory for psychological safety: a warm hide, a cool hide, and a humid hide (moistened with sphagnum moss or paper towels) to assist in shedding.
⚠️ SOLITARY ANIMAL WARNING
NEVER house Leopard Geckos together. They are strictly solitary. Cohabitation leads to "bullying" (one gecko laying on another is NOT cuddling, it is dominance), severe injuries, tail loss, or death.
☀️ UVB & Crepuscular Lighting Needs
Leopard Geckos are crepuscular (active at dawn/dusk). While they can absorb Vitamin D3 via supplements, providing low-level UVB promotes natural behaviors and bone health.
Ferguson Zone Classification:
- ★ Zone 1 (Leopard Geckos): Shade dwellers. Target UVI range: 0.5 to 1.5 in the basking area.
- Zone 2-4: Too intense. Can cause ocular stress and skin burns in this species.
UVB Requirements:
- Type: T5 HO Linear Tube (ShadeDweller style).
- Strength: 5% to 7% (Arcadia ShadeDweller is the industry favorite).
- Coverage: Only cover 1/3 of the enclosure length to provide a "UV Gradient."
📐 The "Mesh Factor" (UV Safety)
Because Leopard Geckos need very low UV levels, the screen mesh density must be accounted for:
- Over-Mesh: Standard screens block 30-40% of UV. A 7% bulb on top is usually safe at a 10-12" distance.
- Under-Mesh: Mounting inside requires a 5% bulb or a much higher distance to avoid "snowblindness" in the gecko.
🌡️ Temperature & Humidity Gradients
Leopard geckos rely on "belly heat" for digestion, but ambient air temperature is equally important for their immune system.
| Requirement | Specification |
|---|---|
| Warm Side Basking (Surface) | 90°F - 93°F |
| Ambient Warm Side (Air) | 83°F - 86°F |
| Cool Side Ambient | 72°F - 77°F |
| General Humidity | 30% - 40% (Arid) |
| CRITICAL LOWER LIMIT | NEVER BELOW 60°F (Night) |
| CRITICAL UPPER LIMIT | NEVER ABOVE 95°F (Ambient) |
Pro Tip: Use a **Deep Heat Projector (DHP)** or a Halogen Flood. These provide IR-A and IR-B heat which penetrates deep into the muscle tissue, mimicking the sun much more effectively than heat mats.
🦗 Nutrition & 100% Insectivore Diet
Leopard Geckos are strict insectivores. They cannot digest plant matter of any kind.
Staple Insect Options:
- Dubia Roaches: High protein, low fat, easy to store.
- Crickets: Stimulate hunting behavior; must be gut-loaded.
- Mealworms: Reliable staple; ensure gecko is hydrated to digest the chitin.
- Silkworms: High in calcium and serrapeptase.
Supplementation Frequency:
| Gecko Age | Calcium (with D3) | Multivitamin |
|---|---|---|
| Juvenile | Every Feeding | 1x per week |
| Adult | 2x per week | 1x every 2 weeks |
⚠️ WARNING: FATTY TREATS
Waxworms and Superworms are "Lizard Junk Food." Feeding these too often causes fatty liver disease and obesity. They should be treats only (1-2 times a month).
🌿 Substrate Safety & Digging Needs
Choosing a substrate is critical for joint health and preventing impaction.
Recommended Safest Options:
- Slate or Stone Tile: Naturalistic, impossible to ingest, and files down claws.
- Safe Mix (70/30): A mix of Organic Topsoil and Play Sand. Only for healthy adults with perfect husbandry.
- Paper Towels: Mandatory for quarantine and monitoring health.
🚨 FATAL SUBSTRATE HAZARDS
- Calcium/Vita-Sand: The most dangerous choice. It neutralizes stomach acid and clumps into a rock in the gut.
- Reptile Carpet: Breeding ground for bacteria. Snags and rips out claws and teeth.
- Loose Wood Chips: Causes internal punctures if accidentally swallowed during hunting.
📝 Daily & Monthly Maintenance
✅
Daily: Remove feces/urates (Geckos usually pick one corner to use as a bathroom).
✅
Daily: Clean and refill the water bowl with fresh, dechlorinated water.
✅
Daily: Re-mist the humid hide (should always be damp, not soaking).
✅
Weekly: Sanitize feeding tongs and bowls.
✅
Monthly: Deep clean enclosure with a reptile-safe disinfectant (e.g., F10).

❓ Frequently Asked Questions (FAQ)
What is a "Wet Hide"?A hide filled with damp moss or paper towels. It creates a micro-climate of high humidity that allows the gecko to peel its skin cleanly.
Why is my gecko eating its own shed?This is natural. They do it to recycle nutrients (calcium) and to remove evidence of their presence from predators.
Do they need a heat mat?While common in the past, overhead heat (DHP) is now preferred as it provides more natural infrared radiation.
Can I feed them fruit?No. Leopard geckos cannot process sugar or plant fiber. It will cause severe digestive distress.
Why is its tail getting skinny?This is a major red flag for parasites (like Pinworms or Crypto) or malnutrition. See an exotic vet immediately.
What is "Enigma Syndrome"?A genetic neurological disorder in specific color morphs that causes spinning and seizures. Avoid "Enigma" or "White & Yellow" morphs if they show "wobble."
Can they drop their tails?Yes. If grabbed or terrified, they will sever their tail. It will regrow, but as a shorter, smoother "turnip" tail.
Why is my gecko "screaming"?Juveniles make a high-pitched barking sound when scared. They usually grow out of this once they realize you aren't a predator.
How long do they sleep?They are active during twilight. Expect them to stay in their hides during the peak of the day.
What is "Stick Tail" disease?A common name for Cryptosporidiosis, a highly contagious and often fatal parasitic infection.
Do they need water?Yes. They drink from a bowl. Dehydration leads to "stuck shed" on the toes, which can cut off circulation and cause toe loss.
Why are its eyes sunken?This is a sign of severe dehydration or internal illness.
Can I use a red light?No. Red light disrupts their sleep cycle and can damage their vision over time. Use heat sources that produce no light.
What is "brumation"?A winter slowdown where they eat less and sleep more. It is triggered by cooler temperatures and shorter daylight hours.
How can I tell the gender?Males have visible pre-anal pores (a V-shape) and hemipenal bulges at the base of the tail. Females do not.
