Bearded Dragon Care: A Complete Beginner Hub
Bearded dragons are a top beginner lizard, but only with a large enclosure, strong heat, real UVB and an age-appropriate insect-and-greens diet. This hub covers whether a beardie suits you, costs by region, tank setup, and the daily care routine.
Quick answer
A bearded dragon is one of the best beginner lizards, but only if you give it a big enclosure, strong heat, real UVB lighting and a varied insect-and-greens diet. Get the setup right before you bring one home: a spacious tank of at least 120 x 60 x 60 cm (4 x 2 x 2 ft) for an adult, a basking surface around 38-42°C, a UVB tube, and a daily feeding and cleaning routine. Done well, a "beardie" commonly lives 8-12 years, sometimes longer.

Is a bearded dragon right for you?
Bearded dragons are calm, day-active and tolerant of gentle handling, which is exactly why they are so popular with first-time reptile keepers. But they are a long-term commitment and not a cheap one. The enclosure, lighting, thermostat and ongoing UVB replacements add up, live insects are a recurring cost, and the animal needs daily attention for a decade or more. Reptiles also hide illness well, so a good keeper is a quietly observant one.
Line up an exotics vet before you ever need one. Not every clinic treats reptiles, and this varies sharply by region: large cities in the US, UK, Australia and much of Europe have dedicated reptile or exotics practices, while in Hong Kong, Taiwan, Japan, Korea and Singapore reptile-savvy vets exist but are fewer and often concentrated in the biggest cities. Find yours, save the number, and you will not be scrambling in an emergency.
A good setup has a warm basking end, a cool retreat, UVB and a shallow water dish.
What it costs to start and keep
Budget honestly before you commit. Costs vary by region and whether you buy new or second-hand, but the shape is the same everywhere: a large one-off setup cost, then modest ongoing running costs. The table gives rough all-in starting ranges for a complete adult setup (enclosure, lighting, thermostat, decor) plus the dragon.
| Region | Starter setup + dragon | Monthly running |
|---|---|---|
| US | US$400-800 | US$30-60 |
| UK | GBP350-700 | GBP25-50 |
| Australia | A$600-1200 (permit may apply) | A$40-70 |
| Canada | C$500-1000 | C$40-70 |
| Eurozone | EUR400-750 | EUR30-55 |
| Hong Kong | HK$3,000-6,000 | HK$250-500 |
| Taiwan | NT$12,000-25,000 | NT$1,000-2,000 |
| Japan | JPY50,000-100,000 | JPY4,000-8,000 |
| Korea | KRW500,000-1,000,000 | KRW40,000-80,000 |
Running costs are mainly electricity for heating and lighting, live insects, greens, supplements and periodic UVB tube replacement. One note on regulations: in Australia, bearded dragons are native wildlife and keeping one usually requires a state reptile licence, and interstate movement is restricted. Elsewhere they are generally unrestricted pet-trade animals, but always check your local rules first.
Setting up the enclosure
Provide a large, well-ventilated enclosure with a clear thermal gradient: a warm basking end and a cooler end so your dragon can choose its temperature. For an adult, aim for at least 120 x 60 x 60 cm (4 x 2 x 2 ft) of floor space, and bigger is better. Use a good basking lamp on a thermostat to create the hot spot, and add a separate UVB tube running much of the length of the tank, replaced on schedule because its output fades before the light visibly dies. Include a hide, a basking branch, and a shallow water dish.
Substrate is one of the topics beginners argue about most, and there are a few legitimate camps:
- Solid / non-particulate (tile, sealed lino, reptile carpet, paper towel): the safest choice for babies and any dragon prone to grabbing substrate, because there is nothing loose to swallow. Easy to clean; less naturalistic.
- Loose desert substrate (washed play sand, or soil-sand mixes): allows natural digging and looks like the wild habitat, but carries an impaction risk if a dragon ingests a lot, especially juveniles. Experienced keepers use it with healthy adults and correct temperatures.
- Bioactive (a soil/sand/clay base with clean-up invertebrates and sometimes plants): increasingly popular, mimics the natural environment and processes waste biologically, but it is the most work to build and get stable, and not the easiest starting point.
A common, sensible path is to start babies on solid substrate and only move to loose or bioactive setups once the dragon is a healthy, well-grown adult.
Heat, light and UVB
Bearded dragons come from hot, sunny habitats, so heat and light are non-negotiable. You need a warm basking spot (about 38-42°C for adults, a little hotter for juveniles), a meaningful drop toward a cool end around 24-28°C, and a night-time temperature that is cooler but not cold (roughly 18-24°C). Always run heat sources through a thermostat and verify temperatures with a probe or infrared thermometer at basking-surface level, not by guessing from the bulb's wattage.
UVB is essential: without it, dragons cannot make vitamin D3, cannot absorb dietary calcium, and develop metabolic bone disease. Use a good-quality linear T5 UVB tube (the widely used strengths for a well-designed enclosure are 10-12% / "desert" grade), positioned correctly for the distance to the basking spot and adjusted if it sits behind mesh, which cuts UVB. Diarise replacement every six to twelve months per the manufacturer, because a tube keeps producing visible light long after its useful UVB has faded.
Juveniles eat more insects; adults eat more greens, with calcium dusting.
Feeding and daily care
Feed a varied diet that shifts with age. Juveniles eat more protein (appropriately sized insects) and grow fast; adults eat proportionally more leafy greens and vegetables with fewer insects. The reliable prey-size rule: never feed anything wider than the space between the dragon's eyes, which prevents choking and gut impaction. Dust insects with calcium and use a reptile multivitamin as advised, gut-load feeder insects before offering them, and provide fresh water, removing uneaten food. Spot-clean daily and do a full clean regularly.
There is a genuine debate about feeding style. Most keepers use scheduled meals, which makes it easy to track appetite (an early illness signal) and keep adults lean. A minority free-feed greens by leaving a salad in all day for grazing, which suits adults on a greens-heavy diet but makes it harder to notice a drop in appetite. For insects, scheduled feeding is the norm, because loose feeders can bite a resting dragon and free-feeding protein leads quickly to obesity.
Getting ready before your dragon arrives
The most common beginner mistake is buying the dragon first and the setup second. Do it the other way round, build and test everything, and let the enclosure "burn in" for about a week so you can fix any heat or UVB gaps before a live animal depends on them.
