Leopard Gecko Care For Beginners: Complete Guide to A Happy, Healthy Gecko

LEOPARD GECKO BASICS:

• Lifespan: 15-20 years
• Adult size: 7-10 inches
• Enclosure: 20 gallon minimum for one gecko
• Temperature: 88-92F warm side, 70-75F cool side
• Diet: Live insects (crickets, mealworms, dubia roaches)
• Beginner friendly: YES — one of the best reptiles for beginners

If you are looking for your first reptile, the leopard gecko is one of the best choices you can make.

They are hardy, manageable in size, do not require UV lighting (unlike many reptiles), have docile temperaments, and live remarkably long lives — often 15-20 years with good care.

They are also one of the most beautiful reptiles in the hobby, with stunning spotted patterns and a wide variety of color morphs.

This complete guide covers everything you need to give your leopard gecko the best possible life.

About Leopard Geckos

Scientific name: Eublepharis macularius Origin: Dry grasslands and rocky desert of South Asia (Pakistan, India, Afghanistan) Adult size: 7-10 inches (18-25 cm) Weight: 45-65 grams (adults) Lifespan: 15-20 years in captivity with good care Activity: Crepuscular (most active at dawn and dusk)

Why they are great for beginners:

• Hardy and forgiving of minor care mistakes
• Do not require UV lighting (simpler setup)
• Docile and generally tolerate handling well
• Manageable size
• Fascinating to observe and interact with

Housing Your Leopard Gecko

Enclosure Size

Minimum for one adult leopard gecko:

• 20 gallon tank (24 x 12 x 12 inches)
• Bigger is always better — 40 gallon breeder tank is ideal

For two geckos (one male, one female only — never two males):

• 40 gallon minimum

Enclosure type:

• Glass terrarium with screen lid: most popular
• PVC or wooden enclosures: excellent for heat retention
• Avoid: screen enclosures (cannot hold heat)

---

Temperature Setup

Temperature is the most critical aspect of leopard gecko care.

Leopard geckos are ectotherms — they regulate body temperature using their environment.

Required temperature gradient:

• Warm side: 88-92 F (31-33 C) — for digestion and activity
• Cool side: 70-75 F (21-24 C) — for cooling down
• Nighttime: Can drop to 65-70 F (18-21 C)

How to create the gradient:

• Under-tank heater (UTH) or heat mat on ONE SIDE only
• MUST use a thermostat with the heat mat — without one, it can overheat and burn your gecko
• Ceramic heat emitter for additional heat if needed
• Check temperatures with digital thermometers or temperature gun (not stick-on thermometers — inaccurate)

WARNING: Never use heat rocks. They cause severe burns.

Lighting

Leopard geckos are crepuscular and do not require UV lighting to survive.

However:

• A low-level UVB light (2.0 or 5.0) is now recommended by many reptile vets
• Provides vitamin D3 through natural means
• May improve overall health and behavior
• If no UVB: must supplement vitamin D3 through dusting (see Diet section)

Day/night cycle:

• 12-14 hours light in summer, 10-12 in winter (mimics natural cycle)
• Use a timer for consistency
• Avoid bright lights at night (disrupts sleep)

---

Substrate (Flooring)

Safe substrates:

• Paper towels: easiest to clean, best for hatchlings and sick geckos
• Reptile carpet: easy to clean, reusable
• Tile (slate or ceramic): excellent, easy to clean, holds heat well
• Bioactive mix (topsoil and sand): natural, requires more setup

AVOID:

• Loose sand (impaction risk, especially for juveniles)
• Calcium sand (marketed as safe but causes impaction)
• Walnut shell (sharp edges, impaction risk)
• Cedar or pine substrate (toxic)

---

Hides

Leopard geckos need hides to feel secure. Without adequate hides, they become chronically stressed.

Required hides:

• Warm side hide (on or near heat mat)
• Cool side hide
• Moist hide (middle temperature) — essential for shedding

Moist hide setup:

• Plastic container with lid
• Cut entrance hole in side
• Fill with damp sphagnum moss or paper towels
• Keep consistently moist (not soaking)
• This is where geckos go to shed — critical for preventing stuck shed

---

Feeding Your Leopard Gecko

Leopard geckos are insectivores — they eat only live insects.

They do not eat vegetables, fruit, or commercial dry reptile food.

Best Feeder Insects

Crickets:

• Most nutritious staple feeder
• Must be gut-loaded (fed nutritious food) before feeding to gecko
• Dust with calcium + D3 and vitamin supplements

Dubia roaches:

• Excellent nutritional profile
• Less odor than crickets
• Easy to keep
• Cannot climb smooth surfaces (easy to contain)

Mealworms:

• Convenient, easy to keep in fridge
• High in fat — use as treat, not staple
• Fine for adult geckos, avoid for juveniles

Waxworms:

• Treat only — like candy for geckos
• Very high fat, addictive
• Feed max 1-2 per week

Hornworms:

• High moisture content — good for hydration
• Low fat, good nutrition
• Excellent occasional feeder

---

Feeding Schedule

Juveniles (under 6 months):

• Feed daily
• As many crickets as they will eat in 15 minutes (usually 5-10)

Sub-adults (6-12 months):

• Feed every other day

Adults (12 months+):

• Feed every 2-3 days
• 6-10 appropriately sized insects per feeding

Rule for insect size: Never feed insects larger than the space between your gecko’s eyes. Too-large insects can cause impaction or injury.

---

Supplementation — Critical

Leopard geckos develop metabolic bone disease (MBD) without proper supplementation.

Required supplements:

Calcium with D3:

• Dust every feeding if no UVB light
• Dust every 2-3 feedings if using UVB light

Multivitamin:

• Dust once per week
• Provides vitamins A, E, and other nutrients

How to dust: Place insects in a bag with supplement powder, shake gently, feed immediately.

Gut loading:

• Feed insects nutritious food 24-48 hours before feeding to gecko
• Good gut load: leafy greens, carrots, sweet potato, commercial gut load
• Well-fed insects = more nutritious meal for your gecko

---

Water

• Fresh water in a shallow dish at all times
• Change daily
• Bowl must be shallow — leopard geckos can drown in deep water bowls
• Mist the moist hide regularly (not the whole enclosure)

---

Handling Your Leopard Gecko

Leopard geckos are generally the most handleable beginner reptile.

Building trust — first 2 weeks:

• Do not handle — allow gecko to settle in
• Let them see you regularly near the enclosure
• Offer food from tongs to start positive association

Beginning handling:

• Start with 5-10 minute sessions
• Support the full body — never grab by tail
• Let gecko walk from hand to hand
• Stay low (sit on floor) in case of falls

TAIL WARNING: Leopard geckos can drop their tails (autotomy) when frightened or grabbed.

• The tail grows back, but never looks the same
• Never grab or restrain the tail
• A dropped tail is not an emergency but requires clean environment

Signs your gecko does not want to be handled:

• Tail wagging (similar to a cat — warning signal)
• Trying to escape
• Biting
• Hissing

Respect these signals and put gecko back in enclosure.

Common Health Issues

Metabolic Bone Disease (MBD)

Most common preventable disease.

Caused by: Calcium and vitamin D3 deficiency

Symptoms:

• Rubbery, soft jawbone
• Tremors or twitching
• Difficulty walking
• Deformed limbs or spine

Prevention: Proper supplementation and/or UVB lighting Treatment: Vet-prescribed calcium supplementation and UVB light

Stuck Shed (Dysecdysis)

Incomplete shedding leaves retained skin — can cut off circulation.

Common areas: Toes, tail tip, around eyes

Prevention: Moist hide always available Treatment: Soak gecko in warm water for 15 minutes, gently remove stuck shed with damp cotton swab. See vet if shed around eyes.

Cryptosporidiosis (Crypto)

Parasitic infection — serious and incurable. Symptoms: Weight loss despite eating, regurgitation, wasting Highly contagious between reptiles — quarantine any new gecko before introducing

Impaction

Caused by ingesting substrate or too-large prey. Symptoms: Loss of appetite, bloating, no bowel movements Prevention: Safe substrate, appropriately sized prey Treatment: Warm soaks, gentle belly massage, vet if severe

Signs of a Healthy Leopard Gecko

• Alert and active during crepuscular hours
• Clear eyes, no discharge
• Clean nostrils
• Body weight appropriate (not too thin, not obese)
• Eats regularly
• Sheds completely without retained skin
• Regular normal droppings
• Fat tail (fat stored in tail indicates good health)

Frequently Asked Questions

Q: Do leopard geckos need UV light? A: They can survive without it, but a low-level UVB light is now recommended by most reptile vets for better health. If no UVB: supplement calcium with D3 every feeding.

Q: Can leopard geckos live together? A: One adult male can live with one or two adult females. NEVER house two males together — they will fight seriously. Two females can sometimes cohabit but monitor carefully. Juveniles should be housed individually.

Q: How do I know if my leopard gecko is male or female? A: Males have visible hemipenal bulges at the base of the tail and a clear row of femoral pores. Females have no bulges and faint or no femoral pores. Sexing is reliable after 3-4 months of age.

Q: My leopard gecko is not eating. What should I do? A: Common reasons: shedding, temperature too low, stress from new environment, illness, or breeding season (females). Check temperatures first. If not eating for 2+ weeks with no other explanation, see a reptile vet.

Q: My gecko dropped its tail. What do I do? A: Keep the enclosure very clean to prevent infection of the tail stump. Remove any tank mates. The tail will regrow, but will look different (fatter, different pattern). See a reptile vet if the stump does not heal cleanly within a week.

Q: How often do leopard geckos shed? A: Juveniles shed every 2-3 weeks. Adults shed every 4-8 weeks. Always ensure the moist hide is available. Geckos usually eat their shed skin (this is normal — they recycle nutrients).
