The complete beginner's guide to leopard gecko care, covering enclosure setup, feeding schedules, temperature requirements, and the mistakes that trip up every new owner.
Leopard geckos are one of the best reptiles for first-time owners. They're calm, handleable, and don't need a room-sized enclosure. But "beginner-friendly" doesn't mean "no effort required." The difference between a gecko that thrives for 20 years and one that struggles comes down to a handful of decisions you make in the first week.
This leopard gecko care guide covers the essentials: housing, heating, feeding, health monitoring, and the common mistakes that send new keepers scrambling to forums at midnight. If you're thinking about getting your first leopard gecko, or you just brought one home and realized you have questions, you're in the right place.
Leopard Gecko Enclosure Setup
Tank Size
Juveniles (0-6 months): A 10-gallon tank works well. Baby geckos can feel overwhelmed in large spaces, struggle to locate food, and feel exposed. A smaller enclosure gives them security while they're growing.
Adults (6+ months): A 20-gallon long tank is the minimum. The key word is "long." Leopard geckos are terrestrial. They don't climb. They need horizontal floor space, not vertical height. A 20-gallon long measures 30" x 12" x 12", which provides enough room for a proper temperature gradient and three hides.
Upgrade option: A 40-gallon breeder (36" x 18" x 16") is excellent if you have the space. More room means more enrichment opportunities and a more natural temperature gradient.
Always choose a tank that's wider than it is tall. Your gecko lives on the ground.
Temperature: The Most Important Part of Leopard Gecko Care
Leopard geckos are ectothermic. They cannot generate their own body heat. Every biological function, from digestion to immune response, depends on the temperatures you provide. Getting this wrong is the single most common cause of health problems in captive leopard geckos.
Warm side surface temperature: 90-94°F. This is measured at ground level, where your gecko's belly contacts the surface. Use an under-tank heater (UTH) or heat mat placed under one end of the tank.
Cool side air temperature: 75-80°F. No heat source needed. Room temperature typically works.
Nighttime: 65-75°F. Leopard geckos benefit from a natural nighttime temperature drop. Keep the heat mat running if your room drops below 65°F.
The thermostat is non-negotiable. A heat mat without a thermostat can reach 120°F+. That's a burn injury, not a basking spot. A basic on/off thermostat costs $20-35 and prevents this entirely. Plug the heat mat into the thermostat, set it to 90°F, and you're done.
Thermometers: Use two digital thermometers with probes. One on the warm side at ground level, one on the cool side. Not the stick-on dial thermometers sold at pet stores. Those are inaccurate by 5-10 degrees, which is the difference between "comfortable" and "can't digest food."
Substrate for Leopard Geckos: Safe Options
Substrate choice is one of the most debated topics in leopard gecko care. Here's the practical guide:
For juveniles: Paper towels or reptile carpet. Period. Baby geckos are prone to impaction (intestinal blockage from swallowing substrate particles). Paper towels are ugly but safe, cheap, and make it easy to monitor droppings.
For adults: You have several safe options:
- Paper towels/newspaper: Functional and sanitary. Not pretty, but effective long-term.
- Slate or ceramic tile: Holds heat well from the UTH, easy to clean, looks clean. Cut to fit from hardware store pieces.
- 70/30 topsoil-to-play-sand mix: More natural, allows digging behavior. Safe for adults when properly mixed.
Avoid: Loose calcium sand (marketed for reptiles but causes impaction), wood chips, walnut shell, and any fine-particle substrate for juveniles.
Hides: Your Gecko Needs Three
Leopard geckos are crepuscular, meaning active at dawn and dusk. They spend most of their time hiding. This isn't shyness. It's biology. They need secure hiding spots to feel safe enough to eat, digest, and behave normally.
Three hides minimum:
- Warm hide: Positioned over the heat mat. Your gecko digests food here.
- Cool hide: On the opposite end. For thermoregulation.
- Moist hide: A tupperware container with an entrance cut in the lid, filled with damp sphagnum moss. This is essential for healthy shedding.
The moist hide is the one people skip. Don't. Leopard geckos shed their entire skin in one piece. Without adequate humidity during shedding, the skin sticks. Stuck shed constricts blood flow to toes and tail tips, causing tissue death. A $3 tupperware container with damp moss prevents this entirely.
Good hides are snug (the gecko should feel enclosed), have one entrance (multiple exits feel insecure), and are opaque (they want darkness).
Leopard Gecko Feeding Guide
What to Feed
Leopard geckos are insectivores. Their diet consists entirely of live insects:
- Crickets: The standard staple. Widely available, nutritious when gut-loaded.
- Dubia roaches: Higher in protein, lower in chitin than crickets. Many keepers consider these the best feeder insect.
- Mealworms: Good staple, easy to store. Less nutritious than crickets or dubias but perfectly acceptable.
- Waxworms: High in fat. Use as occasional treats only. Geckos can become addicted and refuse other foods.
- Hornworms: Good hydration source, high in calcium. Excellent supplemental feeder.
Gut-loading matters. Your gecko is eating whatever the insect ate. Feed your crickets or roaches fresh vegetables and commercial gut-load formula 24 hours before offering them. Starved insects equal malnourished geckos.
Feeding Schedule
Babies and juveniles (under 12 months): Feed daily. Offer as many appropriately sized insects as they'll eat in 15 minutes.
Adults (12+ months): Every other day, or every 2-3 days. 5-7 insects per feeding session.
"Appropriately sized" means no wider than the space between your gecko's eyes.
Supplements: Preventing Metabolic Bone Disease
Metabolic bone disease (MBD) is the number one killer of captive leopard geckos, and it's 100% preventable with proper supplementation.
Every feeding: Dust insects with calcium powder containing vitamin D3.
Once per week: Dust with a reptile multivitamin instead of the calcium.
Keep a small dish of plain calcium powder (without D3) in the enclosure at all times. Some geckos will lick it as needed to self-supplement.
Leopard Gecko Health: What to Watch For
Signs of a Healthy Gecko
- Plump tail (roughly as wide as the neck)
- Clear, bright eyes
- Active during evening hours
- Eating consistently
- Clean, complete sheds
Warning Signs
- Thin or stick-like tail: Fat reserves depleted. Weight loss needs investigation.
- Stuck shed: Especially on toes and tail tip. Increase moist hide humidity.
- Lethargy during active hours: Could indicate temperature issues or illness.
- Runny or discolored stool: Possible parasite infection. Vet visit recommended.
- Swollen joints or jaw: Classic sign of metabolic bone disease. Requires veterinary treatment.
Find a Vet Before You Need One
Not all veterinarians treat reptiles. Search for an exotic or reptile veterinarian in your area now, before an emergency. Ask if they specifically see leopard geckos. Save the contact information.
10 Leopard Gecko Mistakes Beginners Make
- No thermostat on the heat mat. Burns happen. $25 prevents them.
- Calcium sand substrate for juveniles. Causes impaction.
- Skipping the moist hide. Leads to stuck shed and lost toes.
- Cohabitation. Leopard geckos are solitary. One per tank. Always.
- Using stick-on thermometers. They're inaccurate. Use digital probes.
- Red "nighttime" heat lamps. Geckos can see red light. It disrupts sleep. Use a ceramic heat emitter if needed.
- Handling too soon. Wait 1-2 weeks after bringing your gecko home before handling.
- Not gut-loading feeder insects. Empty insects equal empty nutrition.
- Skipping calcium supplementation. MBD is preventable. Supplement every feeding.
- Ignoring gradual weight loss. Weigh monthly with a kitchen scale. Track the numbers.
Handling Your Leopard Gecko
New leopard geckos need a settling-in period before handling. Wait at least 7-14 days after bringing your gecko home. During this time, provide food, water, and correct temperatures, but minimize interaction. Let the gecko learn that the enclosure is safe before introducing the giant warm hand.
First handling sessions: Start with 5 minutes. Place your hand flat in the enclosure and let the gecko walk onto it. Don't grab from above, as this mimics a predator. Scoop gently from below or the side.
Building trust: Handle 3-4 times per week for 10-15 minutes. Consistency matters more than duration. A gecko that's handled regularly becomes calm and comfortable. One that's handled unpredictably stays skittish.
When not to handle:
- During the first 48 hours after feeding (risk of regurgitation)
- When the gecko is in shed (they're stressed and may be more defensive)
- If the gecko is actively tail-rattling or vocalizing (signs of stress or fear)
Tail drops: Leopard geckos can drop their tails as a defense mechanism. It grows back, but the regenerated tail looks different and the gecko loses its fat reserves. Gentle, consistent handling makes tail drops extremely rare.
Is a Leopard Gecko Right for You?
Before committing, consider honestly:
Time: 5-10 minutes daily, 20-30 minutes weekly for deeper cleaning.
Money: $200-400 initial setup, $20-40/month ongoing.
Lifespan: 15-20 years. Longer than most dogs.
Bugs: You must keep live insects in your home. Crickets chirp. Roaches look alarming. This is non-negotiable.
Expectations: Your gecko will be invisible most of the day. It hides. That's normal. If you want a pet that greets you at the door, get a dog.
Vet access: You need a reptile-experienced vet. Not all veterinarians treat geckos. Find one before you need one.
If none of that scares you, a leopard gecko will reward you with two decades of quiet, fascinating companionship. They're not cuddly. They're better than that. They're interesting.
