Bearded Dragon Care: Tank Setup, Heat and UVB, Diet and Lifespan

The bearded dragon is a calm lizard from the dry inland regions of Australia, and one of the most popular pet reptiles in the world [1]. It tolerates gentle handling better than many lizards, but it depends on you completely for heat, light and food [1]. Here is the quick guide to keeping one safely.

Bearded dragon quick facts

What tank does a bearded dragon need?

A roomy one, with a warm end and a cooler end. The Merck Veterinary Manual prefers wooden or fibreglass vivaria to glass tanks for lizards, because glass insulates poorly and temperatures can swing a lot [1].

• Space: a university veterinary hospital advises an enclosure several times the dragon's full length, tail included [2].
• Hides: one hide at the warm end, one at the cool end, plus a dedicated basking spot [2].
• Substrate: newspaper, reptile carpet or artificial turf, or organic options such as bark chips or recycled paper pellets, changed regularly [1].
• Avoid: gravel and small pebbles, which can be swallowed by accident [1].
• Humidity: bearded dragons come from a dry habitat and prefer moderate humidity rather than damp air (a US veterinary teaching hospital suggests roughly 40–60%) [2]. Very dry conditions, though, can contribute to poor shedding [4].

What heat and lighting does a bearded dragon need?

Reptiles don't warm themselves the way we do, so the tank needs a heat gradient: a heat source at one end and a cooler side to retreat to [1].

• Temperature: for lizards of this type, Merck gives a daytime zone of about 25–32°C, a basking spot about 5°C warmer, and nights about 5°C cooler [1]. Bearded-dragon-specific guidance puts the basking spot at the hotter end [2]. Use a thermometer, and ask a reptile vet about the right range for your dragon.
• Control: run heat sources through a thermostat, and guard them so the dragon can't touch them directly [1].
• UVB light: essential for day-active lizards to make vitamin D3 and regulate calcium [1]. Place a fluorescent UVB tube within about 30 cm of the dragon, with no glass or mesh in between [1][2].
• A window is not enough: window glass filters out UVB, so sunlight through a window can't replace a UVB bulb [2].
• Changing the bulb: UVB output fades over time, even while the bulb still glows. The general reptile rule is roughly every 9–12 months; bearded-dragon guidance suggests changing it sooner for young dragons [1][2].
• Day length: about 12 hours of light and 12 hours of dark [1].

What do bearded dragons eat?

Bearded dragons eat both insects and plants [1]. Fast-growing young dragons eat far more live insects than plants. Adults eat mostly dark leafy greens and chopped vegetables, with a smaller share of insects and only a little fruit [2].

• Calcium: dust insects with a calcium supplement just before feeding. This helps prevent bone disease [1].
• Balance: every reptile needs the right calcium-to-phosphorus balance, plus vitamin D3 from supplements or UVB light [1].
• The right schedule: how often to use supplements differs for young and adult dragons [2], so agree on it with a licensed vet who treats reptiles.

Is a bearded dragon a good pet for beginners and children?

Often yes, for beginners. Merck describes it as more tolerant of regular, gentle handling than many pet lizards [1][3]. Its care is still an adult's responsibility, and hygiene is a core part of it.

Salmonella: the US Centers for Disease Control and Prevention (CDC) says Salmonella is the most common germ carried by reptiles and amphibians. A reptile can carry it while looking completely healthy, and spread it to its tank and equipment [5].

• Wash your hands with soap and running water after touching or feeding your dragon, after touching its droppings, tank or equipment, after cleaning, and before eating or drinking [5].
• Use alcohol-based hand sanitiser (at least 60% alcohol) only when soap and water aren't available [5].
• Children under 5 should not handle reptiles, their tanks or their equipment. They are at higher risk of serious illness that can need a hospital stay [5].
• Keep the dragon and its equipment out of the kitchen and away from where food is prepared or eaten, and don't let it roam freely around the home [5].

How do I keep a bearded dragon safe in Saudi summer heat?

We found no source specific to Saudi Arabia or to summer heat in bearded dragons. So these are general precautions based on the heat and lighting guidance above [1][2]:

• Keep the tank indoors, away from an outside wall that gets very hot.
• Don't place it in direct sun behind window glass. Glass blocks UVB anyway [2], and the sun can overheat the tank dangerously.
• Rely on a thermostat and a thermometer, not guesswork [1].
• Have a plan for power cuts, because your dragon relies on its tank to manage its body temperature.

What health problems do bearded dragons get?

Many reptile health problems are linked to heat, light and diet, so good daily care is the best prevention [4].

• Metabolic bone disease: the most common bone disease in pet reptiles. It comes from a diet unbalanced in calcium, phosphorus and vitamin D3, together with too little UVB or the wrong temperatures. Fast-growing lizards such as bearded dragons are at particular risk [4].
• Respiratory infection: signs include open-mouth breathing, a runny nose and difficulty breathing [4].
• Adenovirus: Merck names bearded dragons specifically. It spreads through droppings and contaminated surfaces or equipment, and can cause low energy, weakness, weight loss and diarrhoea in young dragons [4].
• Internal parasites: such as coccidia and worms. Their eggs can survive in the tank for weeks, so cleaning and removing droppings are part of prevention [4].
• Mouth rot: a bacterial infection that often starts as tiny purplish-red spots inside the mouth [4].
• Shedding problems: old skin stuck around the toes, tail or eyes. Causes include low humidity and no rough surfaces to rub against [4].

See a licensed vet experienced with reptiles if you notice loss of appetite, low energy or weakness, an unusual walk, swelling or a changed shape of the jaw, legs or spine, breathing difficulty, diarrhoea, or any sudden change in behaviour [4]. These need a vet, not home treatment.

What should I check before buying or adopting a bearded dragon?

• Good body condition: hip bones and tail bones should not stick out [3].
• Healthy skin: no scratches or bite marks [3].
• A clean vent: not stained with urine or caked with droppings [3].
• Clear eyes and nostrils: no swelling, crusting or discharge [3].
• Ask for any health record the seller has, and book a check with a licensed vet who treats reptiles.
• Set up the tank first: heat and lighting should be ready and adjusted from day one [1].
• Check the rules with the official authorities before you buy (see the next section).

Costs to plan for: a suitable tank, a heat source with a thermostat, a UVB bulb replaced regularly, live insects and fresh greens, a calcium supplement, check-ups with a reptile vet, and an emergency fund [1][2].

Do I need a permit for a bearded dragon in Saudi Arabia?

We couldn't confirm this, so check before you buy. Saudi Arabia's National Center for Wildlife (NCW) publishes its regulations and lists of predator species that are banned from ownership, trade or import [7]. We found no source that says whether its rules cover bearded dragons. Please confirm directly with the NCW before buying or importing one.

It helps to know that bearded dragons are not listed under CITES, the convention on international trade in endangered species, unlike the dhub [6].

For import, the pet-import rules of the Ministry of Environment, Water and Agriculture (MEWA) on the Anaam platform cover only dogs and cats, and don't mention reptiles [8]. So confirm the current requirements directly with MEWA, the NCW and your airline before making any plans. This is guidance only, and rules can change.

Is the dhub (Uromastyx) a pet?

No. The dhub is protected wildlife, not a pet.

The dhub (spiny-tailed lizard, genus Uromastyx) is a wild lizard native to our region. All its species are listed in CITES Appendix II, which regulates international trade in them [6]. Saudi Arabia's National Center for Wildlife has set out a protection strategy for the dhub, with penalties for breaking its rules, and names uncontrolled illegal hunting as the main reason for its decline [9].

Don't take a dhub from the wild, and don't buy one to keep at home. For the current rules, refer to the National Center for Wildlife [7][9].

Bearded dragon fun facts

• The name comes from the "beard": a pouch of skin under the chin that it can puff out and darken, sometimes to black, especially during territorial displays, stress or courtship [1].
• It belongs to the agamid family, day-active basking lizards that need strong UVB [1].
• The Merck Veterinary Manual describes it as probably the most popular pet reptile in the US [1].

Bearded dragon FAQ

How long do bearded dragons live?

About 5 to 10 years in captivity, according to the Merck Veterinary Manual [1]. The right heat, lighting and diet help it live a longer, healthier life.

Can sunlight through a window replace a UVB bulb?

No. Window glass filters out UVB, so a bearded dragon needs a UVB bulb in its tank [2].

Do bearded dragons carry Salmonella?

Like all reptiles, they can carry it while looking healthy. Wash your hands with soap and water after touching the dragon or its tank, and keep children under 5 from handling it [5].

Can I use gravel in a bearded dragon tank?

It's best to avoid gravel and small pebbles, which can be swallowed. Newspaper or reptile carpet are simpler choices [1].

What's the difference between a dhub and a bearded dragon?

The bearded dragon is a common pet lizard from Australia [1]. The dhub is a protected wild lizard native to our region, and not a pet [6][9].
