Leopard Gecko Care: The Complete Beginner’s Guide

Leopard geckos are one of the best first reptiles for a reason: they are hardy, calm, relatively small, and do not need the large, complex setup that many other reptiles do. They are also long-lived pets, so a little planning up front makes a big difference.

This guide covers everything a beginner needs — size, lifespan, tank setup, heating, feeding, handling, and the mistakes to avoid.

Leopard gecko basics

• Adult size: Usually 7 to 10 inches long, including the tail
• Lifespan: Commonly 15 to 20 years with good care
• Temperament: Generally calm and tolerant of gentle handling once settled in
• Activity: Most active at dawn and dusk
• Space needed: A 20-gallon long tank is the minimum for one adult, but a 40-gallon breeder gives more room for a proper temperature gradient and enrichment

That lifespan is the most important thing to understand before you buy. A leopard gecko is not a short-term pet — it is a commitment for well over a decade.

Tank setup: what you actually need

A good leopard gecko setup is simple, but the temperature gradient matters more than decoration.

Essentials:

• A secure tank with a lid — 20 gallons long minimum, 40 gallons ideal for an adult
• A warm hide, a cool hide, and a humid hide (a hide with damp paper towel or sphagnum moss to help with shedding)
• A heat mat or ceramic heat emitter controlled by a thermostat — never use an unregulated heat source
• A shallow water dish, refreshed daily
• A calcium dish and a feeding dish for insects
• A digital thermometer on both the warm and cool sides

Temperatures to aim for:

• Warm side / basking surface: around 88–94°F (31–34°C)
• Cool side: around 70–77°F (21–25°C)
• Nighttime: can drop a little, but should not fall below about 65°F (18°C)

Leopard geckos do not need special UVB lighting in the same way as bearded dragons, but many keepers now provide low-level UVB as part of a more natural setup. If you use UVB, follow the manufacturer’s distance and replacement guidance.

Substrate for beginners:
Paper towel is the safest, easiest choice for a first gecko, especially for juveniles. It is easy to clean and makes it easy to spot health problems. Avoid loose sand for young geckos, as accidental ingestion while feeding can cause impaction. If you move to a loose substrate later, research it carefully and feed in a separate dish.

Feeding: what do leopard geckos eat?

Leopard geckos are insectivores. In captivity they do well on a varied diet of feeder insects. You can find feeder insects in our shop.

Good staple insects include:

• Crickets
• Dubia roaches
• Mealworms
• Black soldier fly larvae

Feeding guide:

• Juveniles: small insects daily
• Adults: insects every 2 to 3 days
• Offer only as many insects as your gecko will eat in about 15 minutes, and remove uneaten insects

Supplements matter:
Dust feeder insects with calcium, and use a calcium supplement with vitamin D3 on a schedule appropriate to your lighting setup. A multivitamin once or twice a week is also commonly recommended. Do not guess at supplement doses — if you are unsure, ask an experienced keeper or a reptile veterinarian.

Always provide fresh water, and do not feed wild-caught insects, which can carry pesticides or parasites.

Handling and temperament

Give a new gecko a few days to settle in before handling. Start with short, calm sessions, support its body fully, and never grab it by the tail — leopard geckos can drop their tails when stressed, and while a tail can regrow, it will not look the same.

Signs your gecko is settling in well include eating regularly, exploring at dusk, shedding cleanly in one piece, and passing normal droppings.

Avoid handling right after feeding, or while your gecko is shedding, when it is likely to be more sensitive.

Common beginner mistakes

1. No thermostat on the heat source. This is the most dangerous mistake. Heat mats can overheat without one.
2. Too small a tank. A small tank makes a proper warm-to-cool gradient almost impossible.
3. Loose sand for a juvenile. Keep it simple and safe at first.
4. No humid hide. This is the main reason for stuck shed on toes and tails.
5. Feeding insects that are too large. A good rule is no wider than the space between your gecko’s eyes.
6. Handling too soon, or too roughly. Patience in the first week pays off for years.

Leopard gecko FAQ

Are leopard geckos good pets for beginners?

Yes, for most beginners they are one of the easiest reptiles to keep, provided you set up heating correctly and commit to their long lifespan.

Do leopard geckos need a heat lamp?

They need a controlled heat source and a temperature gradient. Many keepers use a heat mat or ceramic heat emitter with a thermostat, rather than a bright basking lamp, because leopard geckos are crepuscular.

How often should I clean the tank?

Spot-clean daily, change water daily, and do a full clean regularly. Paper towel substrate makes this much easier.

Can two leopard geckos live together?

It is safest to house leopard geckos individually, especially males. Cohabitation can lead to stress, competition for food, and injury, even if they appear calm at first.

Getting started

If you are ready to bring one home, start with the setup first — tank, heating, thermostat, hides, and food — and let temperatures stabilise before your gecko arrives.

Browse leopard geckos and starter supplies in the shop, and if you are unsure which setup is right for you, reach out to the team before you order.
