How do you care for a bearded dragon?

Short answer

A bearded dragon needs a 120 × 60 × 60 cm (4 × 2 × 2 ft) enclosure with a basking surface of 40–43 °C (104–110 °F), an ambient cool side of 24–27 °C (75–80 °F), a T5 high-output UVB tube giving UVI 4–6 at basking, daily greens with calcium-with-D3-dusted insects 3–5 times per week, fresh water, and a real 12-hour night with all lights off.

What you're signing up for

Bearded dragons (Pogona vitticeps) are diurnal, omnivorous lizards from the arid inland of Australia. In captivity they're one of the most recommended beginner reptiles because they tolerate handling and have calm, observable personalities — but they're emphatically NOT low-effort. A correctly-kept dragon needs strong UVB, a hot basking surface, an adult-sized enclosure, fresh greens daily and live insects multiple times a week. Get those right and they reach 8–12 years; get them wrong and the most common outcome is preventable metabolic bone disease within the first year.

This pillar guide is the index to the rest of the Reptimo bearded dragon library. Each section here links out to a deeper guide on the specific parameter. Start with the tank setup checklist if you're buying gear, or jump to metabolic bone disease signs if you're worried about an existing dragon.

Enclosure

Adult bearded dragons grow to roughly 50 cm head-to-tail in their first year and patrol horizontally. A 4 × 2 × 2 ft enclosure is the minimum that allows proper thermoregulation between a hot basking zone and a true cool retreat; 5 × 2 × 2 ft is the modern standard preferred across welfare- focused care guides like ReptiFiles.

PVC or PVC-and-wood enclosures hold heat better than glass and let you mount UVB internally without a glass barrier. Glass tanks work but lose heat fast and force higher-wattage bulbs. Most keepers buy the adult enclosure from day one — a hatchling adjusts to a large space within days if you provide enough décor (cork bark, silk plants, a low ledge) to break the floor plan into "rooms".

The deep dive — substrate choices, hides, water dish placement — lives in the dedicated tank setup checklist.

Heating and lighting

Two parallel systems on independent thermostats and a single mechanical timer:

  • Heat: a halogen flood (50–100 W) on a dimming or pulse-proportional thermostat, set so the basking surface reads 40–43 °C (104–110 °F) with an infrared temperature gun on the spot the dragon actually lies on.
  • UVB: a T5 HO linear tube (Arcadia Dragon 12 % or Zoo Med ReptiSun 10.0) covering two-thirds of the enclosure length, mounted inside, giving UVI 4–6 at basking measured with a Solarmeter 6.5.

Run a 12-hour-on / 12-hour-off photoperiod year-round. At night, all heat and light off — bearded dragons need a real night-time temperature drop to sleep and cycle hormones, and red "night-glo" bulbs disrupt that. The full mounting and replacement-schedule detail is in the dedicated UVB guide, plus the temperature deep dive.

Feeding

Bearded dragons are omnivores whose diet shifts with age. Hatchlings need protein for fast growth; adults need fibre and calcium-rich greens to avoid obesity. The split most contemporary care guides converge on, per PetMD:

  • Hatchlings (0–4 months): insects multiple times daily, dusted with calcium-with-D3 most feedings. Greens always available even though they're mostly ignored at this age.
  • Juveniles (4–12 months): insects once daily, greens always available, calcium-with-D3 most feedings, multivitamin weekly.
  • Adults (12 months+): greens daily, insects 3–5 times per week, calcium-with-D3 most insect feedings, multivitamin every 1–2 weeks.

Insect choice: dubia roaches and black soldier fly larvae (calciworms) are the gold standard for nutrition; crickets work but escape and stink; mealworms only as treats (high fat, hard chitin). Greens: collard greens, mustard greens, dandelion greens, escarole. Skip iceberg lettuce (nutritionally empty), spinach and kale long-term (oxalates), and avoid fruit beyond an occasional bite. Detail by life stage: bearded-dragon-feeding-by-age (coming in a future batch).

Hydration and bathing

A shallow ceramic water dish on the cool side, refreshed every 1–2 days, covers most bearded dragons. Many never visibly drink from it — they extract most water from fresh greens, the occasional misted leaf, and weekly 10-minute baths in shallow lukewarm water.

Don't raise tank humidity to "help" hydration: chronic humidity above 50 % significantly raises respiratory infection risk in this dry-dwelling species. If the dragon's eyes are sunken or its skin looks dehydrated, a bath plus a vet appointment is the answer, not a mister.

Common problems and when to see a vet

The Reptimo cross-species warning-signs checklist covers the universal red flags. Bearded-dragon-specific patterns:

  • Refusing food but otherwise active in autumn/winter — likely brumation, normal in adults; check weight weekly. Detailed in the not-eating guide.
  • Weakness in back legs, tremors, "rubber jaw" — metabolic bone disease. Same-week vet appointment, then audit UVB. See MBD signs.
  • Black beard sustained for days + lethargy — stress, illness or brumation. Black beard during basking only is normal.
  • Sunken eyes, weight loss — dehydration; bath, vet, audit greens intake.
  • Open-mouth breathing with mucus, audible wheezing — respiratory infection (humidity too high or temperature too low). Reptile vet within days.

YMYL note: this guide compiles husbandry from authoritative sources and is not a substitute for veterinary advice. For any of the patterns above, book a reptile-experienced vet — bringing a written husbandry log (temperatures, UVB age, feeding, weights) gets a faster diagnosis.

What to skip

Most starter kits include something on this list. Spend the money on UVB and the right enclosure instead:

  • Coloured "night-glo" bulbs (red, blue, "moonlight").
  • Compact twist-in UVB bulbs.
  • Loose calci-sand for hatchlings.
  • Heat rocks (chronic burn risk).
  • Glass lid between the dragon and the UVB tube.
  • Mealworms or pinky mice as a staple food.

Frequently asked questions

How long do bearded dragons live?
Captive bearded dragons typically live 8–12 years with correct husbandry, and well-kept individuals reach 15 years. Most premature deaths are preventable husbandry failures — wrong UVB, chronic dehydration or impaction — not species fragility.
Are bearded dragons good pets for beginners?
Bearded dragons are widely recommended as one of the best beginner lizards because they're docile, diurnal and tolerate handling. They are NOT a low-effort pet: proper UVB lighting, an adult-sized enclosure and daily fresh food are non-negotiable. Expect ~30 minutes of care per day plus a vet budget.
What size tank does an adult bearded dragon need?
120 × 60 × 60 cm (4 × 2 × 2 ft) is the absolute minimum for an adult; 150 × 60 × 60 cm (5 × 2 × 2 ft) is the modern standard preferred by most welfare-focused care sheets. Hatchlings can start smaller but most keepers buy the adult enclosure upfront.
What temperature does a bearded dragon need?
Basking surface 40–43 °C (104–110 °F) for adults, 43–46 °C (110–115 °F) for hatchlings. Ambient cool side 24–27 °C (75–80 °F). Night 18–22 °C (65–72 °F) with all heat and lights off. Use an infrared temperature gun on the basking surface, not a stick-on dial.
What do bearded dragons eat?
Adults: roughly 70 % fresh greens (collard greens, dandelion, mustard greens, escarole) and 30 % insects (dubia roaches, crickets, black soldier fly larvae) dusted with calcium-with-D3. Hatchlings invert this ratio — about 70–80 % insects, fed multiple times daily — because they're growing fast.
How often do bearded dragons need to eat?
Hatchlings (under 4 months): insects 2–3 times daily, greens always available. Juveniles (4–12 months): insects once daily, greens always available. Adults: greens daily, insects 3–5 times per week. Calcium dusted on insects most feedings; multivitamin once weekly.
Do bearded dragons need water?
Yes — a shallow ceramic water dish on the cool side, refreshed every 1–2 days. Most bearded dragons get most of their water from greens and the occasional bath rather than from drinking, but the dish supports hydration during shedding and ambient humidity below the unsafe range.
What humidity should a bearded dragon tank have?
30–40 % ambient is ideal. Sustained humidity above 50 % significantly increases respiratory infection risk in a dry-dwelling desert species. A weekly 10-minute bath in shallow lukewarm water helps shedding without raising tank humidity.
What are signs of a sick bearded dragon?
Sunken eyes, lethargy, refusing food for over a week with stable husbandry, weight loss, runny stools, swollen jaw, tremors or weakness in the back legs, open-mouth breathing with mucus, or a sustained black beard. Any of these in combination is a same-week reptile-vet appointment.
