Bearded Dragon Setup Checklist for Beginners

A bearded dragon is one of the best first lizards you can keep: awake in the daytime, usually happy to be handled, and full of personality. It is also one of the easiest to set up badly, because a bearded dragon needs three things at the same time — real heat, real UVB, and space — and a small tank with a single bulb gives it none of them properly.

This checklist covers everything to have ready before your dragon comes home, in the order that matters most. Print it, tick it off, and do not bring the dragon home until the enclosure is running and the temperatures are stable.

At a glance

Adult size: usually 18–24 inches including the tail
Lifespan: 10–15 years with good care
Temperament: generally calm, alert and tolerant of handling
Activity: diurnal — awake, basking and eating during the day, asleep at night
Difficulty: beginner-friendly, if the heating and UVB are set up correctly from day one

1. The enclosure

This is the item people undersize most often. A baby bearded dragon looks tiny in a big tank, so beginners buy small — and then have to buy again within a year.

Minimum for an adult: 4×2×2 ft (around 120 gallons). That is the size to buy if you can only buy once
For a juvenile: the same adult enclosure works if it has plenty of hides and clutter so the baby does not feel exposed; otherwise start with a 40-gallon and upgrade by about 8–12 months
Type: a front-opening vivarium is easier to clean and handle from than a top-opening tank, and it holds heat better
Ventilation: good airflow matters, but do not put the enclosure in a draught or directly under an air-conditioning vent
Placement: a quiet room, out of direct sun through a window (glass magnifies heat and can cook a dragon), with space around it for the lamps and cables

See our Enclosure & Habitats range for the enclosure types that suit a bearded dragon.

2. Heating: the basking spot and the cool side

A bearded dragon is a desert animal that regulates its body temperature by moving between hot and cool. Your job is to give it both, every day.

Basking spot: 100–110°F (38–43°C) directly under the basking bulb, on a flat rock or branch the dragon can sit on
Warm side air: around 85–90°F
Cool side: 75–85°F (24–29°C), so the dragon always has somewhere to cool down
Night: temperatures can fall to around 65–75°F. If your house drops below that, a ceramic heat emitter (which gives heat without light) is the right fix — never a coloured “night” bulb, which disturbs sleep
Thermostat: every heat source must be on a thermostat. An unregulated bulb can overheat the enclosure or burn a dragon that sits too close
Thermometers: a digital probe thermometer at each end, plus a handheld infrared thermometer to check the basking surface itself. Do not trust a single stick-on dial

If your dragon spends all day pressed against the cool glass, the basking spot is too hot. If it never leaves the basking spot, the cool side is too cold. Watch the animal, not just the dial. See our Heating & Lighting range for basking bulbs, ceramic emitters and thermostats.

3. UVB lighting: non-negotiable

UVB is the single most important piece of a bearded dragon setup, and the one most often got wrong. Without enough UVB, a dragon cannot make vitamin D3, cannot absorb calcium, and develops metabolic bone disease — soft bones, a bent jaw, tremors, and eventually a dragon that cannot move properly. It is slow, painful, and preventable.

Tube, not coil: use a long T5 HO UVB tube (10–12% output) running across about two-thirds of the enclosure, not a small coil bulb in one corner
Placement: inside the enclosure or directly above a mesh top, 12–18 inches from the basking spot, following the manufacturer’s distance guidance. Mesh, glass and plastic all block UVB, so a tube sitting on top of a glass lid does nothing
No obstruction: nothing solid between the tube and the basking spot
Day cycle: 12–14 hours on in summer, 10–12 hours in winter, off at night. A simple timer plug does this reliably
Replacement: UVB tubes weaken long before they stop glowing. Replace a T5 tube every 6–12 months, following the maker’s guidance, even if it still lights up

A dragon with good UVB basks, eats, and grows steadily. A dragon without it goes quiet, stops eating, and gets weaker over weeks. If you are choosing between a cheaper setup and a proper UVB tube, the tube wins every time.

4. Substrate and decor

Safe substrates for beginners: reptile carpet, paper towel (especially for a juvenile), or a solid tile / slate floor. These are easy to clean and carry no impaction risk
Loose substrates: a bioactive soil mix or a suitable loose substrate can work for a healthy adult in the right setup, but it needs more care and is not the best first choice for a baby, which is more likely to swallow substrate while hunting
Avoid: sand on its own, especially calcium sand, and pine or cedar shavings — the first risks impaction, the second is harmful to reptiles
Basking platform: a flat rock or sturdy branch directly under the basking bulb, at the right distance for the target temperature
Hides: at least one hide on the cool side, and a second on the warm side if there is room. A dragon that cannot hide will stress
Climbing: a branch or two at different heights, firmly fixed so it cannot fall on the dragon
Water bowl: shallow, heavy, and changed daily. Most dragons drink little from a bowl and get most of their water from food and bathing, but fresh water must always be available
Food dish: a shallow dish for salads, so greens do not sit on the substrate

See our Substrate & Decor range for safe substrates, hides, branches and dishes.

5. Food: what a bearded dragon actually eats

A bearded dragon’s diet changes with age, and getting the balance wrong is the second most common beginner mistake after UVB.

Juveniles (under 12 months): mostly live insects — around 70–80% insects, 20–30% greens. Feed insects 2–3 times a day, as many as the dragon will eat in about 10–15 minutes
Adults: the balance flips — around 70–80% greens and vegetables, 20–30% insects, with insects offered a few times a week
Safe insects: crickets, dubia roaches, black soldier fly larvae, and locusts. Size them to the dragon: no insect wider than the gap between the dragon’s eyes
Safe greens: collard greens, dandelion greens, mustard greens, squash, and bell pepper. Offer a fresh salad every day, even for a juvenile
Avoid: iceberg lettuce (almost no nutrition), spinach and citrus in quantity, fireflies (toxic), and wild-caught insects, which may carry pesticides
Supplements: dust insects with calcium powder (with D3 if your UVB is not yet proven) at most feedings for a juvenile, a few times a week for an adult, and use a multivitamin once or twice a week
Water: mist the salad lightly, and offer a shallow lukewarm bath a couple of times a week. Many dragons drink during a bath

Never feed a dragon insects you found in the garden, and never leave live crickets in the enclosure overnight — hungry crickets bite a sleeping dragon.

6. Daily and weekly routine

Every day

Fresh salad in the morning, insects at the right frequency for the dragon’s age
Fresh water
Check the basking temperature and that the UVB and heat lamps came on with the timer
Spot-clean any droppings

Every week

A full clean of the water and food dishes
A lukewarm bath (10–15 minutes, water up to the dragon’s shoulders, supervised)
Check the dragon’s weight and condition — a healthy dragon has a full tail base, clear eyes, and an alert posture

Every few months

Replace the UVB tube on schedule
Deep-clean the enclosure and check hides, branches and cables for wear

7. Handling and settling in

First week: leave a new dragon alone to settle in, apart from feeding and cleaning. Handling on day one is the fastest way to a stressed dragon that will not eat
Then: short sessions, 10–15 minutes, a few times a week, building up. Support the whole body, move slowly, and let the dragon sit on your hand or arm rather than gripping it
Signs of stress: a black beard, a flattened body, hiding all day, or refusing food. Give the dragon space and check the temperatures and UVB before handling it again
Shedding: dragons shed in patches, not in one piece like a snake. Do not pull skin off — a lukewarm bath helps it come away on its own. Stuck shed on toes or the tail tip needs a vet, not force
Brumation: some adults slow down, eat less and sleep more in the cooler months. That can be normal brumation, but a first-time keeper should have a vet check a dragon that goes off food before assuming it is brumation

Children can handle a bearded dragon with an adult present, with clean hands before and after — dragons can carry salmonella like all reptiles, so hand-washing is a habit, not an optional extra.

8. Health: when to see a reptile vet

Find a reptile vet before you need one. See one promptly if you notice:

A dragon that stops eating for more than a week (outside brumation, and after checking heat and UVB)
Lethargy, a sunken look, or a dragon that cannot hold itself up
A bent jaw, trembling legs, or difficulty walking — possible metabolic bone disease
Swollen eyes, discharge, or wheezing
Diarrhoea, blood in droppings, or visible parasites
A tail or toes turning dark and not shedding

Most of these trace back to the setup: too cold, too little UVB, or the wrong diet. Fix the setup and get vet advice in the same week — do not wait to see if it sorts itself out.

T5 HO UVB tube (10–12%) across two-thirds of the enclosure, on a timer
Digital thermometers at both ends, plus an infrared thermometer
Safe substrate, basking rock or branch, hides, shallow water and food dishes
Live insects sized to the dragon, fresh greens daily, calcium and multivitamin
A reptile vet’s number saved before the dragon arrives

FAQ

How big a tank does a bearded dragon need?
An adult needs a 4×2×2 ft enclosure (about 120 gallons). Anything smaller makes the temperature gradient impossible — the dragon cannot get both hot enough and cool enough in the same box.

Do bearded dragons need UVB if they get sunlight?
Glass blocks UVB, so sunlight through a window does not count. A proper UVB tube inside the enclosure is essential, even in a sunny room.

What do baby bearded dragons eat?
Mostly live insects — crickets, dubia roaches or black soldier fly larvae — 2–3 times a day, plus a fresh salad offered every day. The insect share falls as the dragon grows.

How often should I bathe my bearded dragon?
A shallow lukewarm bath a couple of times a week is enough for most dragons. It helps with shedding and hydration, and many dragons drink during a bath.

Why is my bearded dragon’s beard black?
A black beard is a stress or dominance signal — a new home, a perceived threat, another dragon in view, or being handled too soon. Check the setup and give the dragon space.

How long do bearded dragons live?
10–15 years with the right heating, UVB and diet. Like any reptile, it is a long commitment — be sure before you buy.

Is a bearded dragon a good first reptile?
Yes, and it is the most forgiving first lizard for a beginner who gets the UVB and heating right. If you would rather start with something that needs no UVB at all, our Leopard Gecko Care Guide is the place to start.

Set the enclosure up first, get the basking spot to 100–110°F and the UVB tube running, and only then bring the dragon home. A bearded dragon that starts life in a correct setup — warm enough, with real UVB, fresh greens every day and insects at the right size — is a dragon that eats well, grows steadily, and is happy to sit on your hand for years.
