Choosing Your First Reptile: Species, Setup and the Equipment Checklist

Four Questions Before Any Species

• Space: can you fit the adult's enclosure? Snakes and bearded dragons need 4–6 feet (1.2–1.8 m) of length.
• Equipment: are you happy running heat lamps, UVB tubes and thermostats every day, and replacing tubes on schedule?
• Food: can you store frozen rodents in your freezer, or keep live insects in the house?
• Time: many reptiles live 15–25 years, and tortoises much longer.

The animal is often the cheapest part. The enclosure, heat, lighting, thermostat, gauges and décor usually cost more, and bulbs, substrate and food keep costing for the animal's whole life.

The Beginner Short List

• Leopard gecko: small, calm, ground-living, eats insects. Needs heat on a thermostat and, ideally, low-level UVB.
• Crested gecko: quiet climber that eats a complete powdered diet; often fine at normal room temperature, but dislikes heat.
• Corn snake: the classic starter snake. Eats reliably and handles well; needs an escape-proof enclosure.
• Ball python: very calm, but can fast for weeks and lives 20–30 years.
• Bearded dragon: friendly and active by day, but needs a large enclosure, strong UVB and daily greens.

Size for the Adult, Not the Hatchling

Almost every reptile sold as a baby looks as though it would fit anywhere. Buy the enclosure for the adult from day one. It saves buying twice and saves moving a settled animal later.

Material matters too: glass or PVC with front doors suits most species; a species that needs high humidity does badly in an all-mesh enclosure that dries out. See terrariums and enclosures.

The Equipment Checklist

• Enclosure sized for the adult of your species.
• Heat source on a thermostat or dimmer, every time. An unregulated heat lamp or mat can burn your reptile or start a fire. Never use a household lamp.
• UVB lighting for day-active species, and low-level UVB for many others. A T5 tube is the modern standard. Output fades before the bulb looks dim, so replace on the maker's schedule. See UVB lighting explained.
• Substrate that suits the species. Some loose beddings can be swallowed with food.
• Digital thermometer and hygrometer with probes, and an infrared thermometer for basking spots. Dial gauges are often wrong.
• At least two hides, so your reptile never has to choose between warmth and feeling safe.
• Food and water: the right food for the species, calcium powder for insect-eaters, and a water dish.

Build It and Test It First

Set the whole enclosure up and run it for a few days before your reptile arrives. Check the thermostat's setting against your thermometer readings at different times of day. This catches faulty equipment before an animal depends on it.

Buying Well

Buy captive-bred from a breeder or a reptile rescue. A good seller answers questions readily, keeps clean enclosures, can show the animal eating, and doesn't rush you. Avoid wild-caught animals (see why).

Health: Preventive Care

Find a vet who treats reptiles before you buy; many practices don't. Book a check-up after your reptile settles. Reptiles can carry salmonella without looking ill, so wash your hands after handling and supervise children.

Some species are restricted in some places, for example sliders in Great Britain and the EU, or snakes in Hawaii. Rules differ by country, so check before you buy.
