How to Care for a Bearded Dragon: Beginner Guide
A complete beginner's guide to bearded dragon care: tank size, basking temperatures, UVB, diet by age, safe substrate, hydration, handling, and signs of illness.
Bearded dragons are one of the best reptiles a first-time keeper can choose. They are docile, curious, active during the day, and they bond with their owners in a way few lizards do. They are not, however, low-maintenance. A healthy bearded dragon depends on the right enclosure, strong UVB, carefully managed temperatures, and a diet that changes as the dragon grows. Get those basics right and you can look forward to 10 to 15 years with a confident, thriving companion. This guide walks you through every essential so you can set up correctly from day one.

The enclosure: bigger is better
Floor space is the single most important feature of a bearded dragon's home. A 40-gallon breeder is the bare minimum for an adult, but a 75 to 120 gallon enclosure is far better because it lets you create a genuine temperature gradient. Bearded dragons are ectotherms, which means they regulate body heat by moving between a warm basking zone and a cooler retreat. In a cramped tank the whole space heats to one temperature and the dragon loses that vital control.
A few rules keep things safe. Never house two bearded dragons together, even two females, because they are territorial and one will bully or injure the other. Choose a solid, easy-to-clean substrate. Avoid loose sand, walnut shell, or fine soil for beginners, since a dragon can swallow particles during feeding and develop impaction, a dangerous gut blockage. Reptile carpet, tile, or sealed surfaces are simple and safe.
Heating and basking
Your dragon needs a hot basking spot and a cool retreat at the same time. Use a household basking bulb pointed at a flat rock or platform and a digital infrared thermometer to read the actual surface temperature. Plug the heat source into a thermostat so it never overshoots. Here is what to aim for:
- Basking surface: 95 to 110F, with babies and juveniles toward the warmer end.
- Cool side: 75 to 85F so the dragon can shed excess heat.
- Night: no extra heat needed if the room stays above about 65F. Avoid colored night bulbs.
Do not rely on the dial on a cheap stick-on gauge. An infrared thermometer reads the basking surface directly, which is the number that actually matters for digestion and comfort.
UVB lighting
UVB is the part new keepers most often get wrong, and it is the part that matters most for long-term health. Bearded dragons use UVB to make vitamin D3, which they need to absorb dietary calcium. Without enough UVB they slowly develop metabolic bone disease, or MBD, which weakens and deforms the skeleton. Use a linear T5 HO 10.0 UVB bulb that spans most of the enclosure length, mount it at the distance the manufacturer specifies, and replace it every 6 to 12 months. The bulb keeps glowing long after its useful UVB output has faded, so mark your calendar.

Diet by age
What your dragon eats depends heavily on age, because young dragons grow fast and need protein while adults need fiber and lower fat. Use this quick reference to keep the basics straight:
| Age | Basking temp | UVB | Diet split |
|---|---|---|---|
| Baby (0 to 5 months) | 100 to 110F | T5 HO 10.0 | ~80% insects / 20% greens, fed often |
| Juvenile (5 to 18 months) | 95 to 105F | T5 HO 10.0 | ~60 to 70% insects, rising greens |
| Adult (18+ months) | 95 to 105F | T5 HO 10.0 | ~80% greens / 20% insects |
Offer staple feeder insects like dubia roaches, crickets, black soldier fly larvae, and the occasional hornworm as a treat. Gut load your feeders with vegetables before serving, and dust them with calcium so your dragon gets the minerals it needs. Provide leafy greens daily, such as collard, mustard, and dandelion greens, and skip spinach and iceberg, which offer little. A light, varied salad becomes the centerpiece of an adult's diet.
Hydration and handling
Bearded dragons get much of their water from food, but a shallow dish, the occasional warm bath, and misting greens all help. Keep humidity moderate and let the enclosure dry between mistings, since constant dampness invites respiratory infection. For handling, go slow. Support the whole body, scoop from the side rather than swooping from above like a predator, and keep early sessions short. With patience, most dragons become calm and genuinely enjoy time out of the tank.
Signs of illness and when to see a vet
Reptiles hide illness well, so learn the warning signs. Prolonged loss of appetite, weight loss, sunken eyes, lethargy, swollen or bent limbs, tremors, runny stool, or open-mouth labored breathing all warrant attention. Stuck shed that tightens around a toe or tail tip can cut off circulation. None of this is something to wait out. Establish a relationship with a reptile or exotic vet early, and reach out promptly when something seems off. Strong UVB, correct temperatures, a proper diet, and a roomy enclosure prevent the vast majority of problems, which is exactly why the basics in this guide are worth getting right from the start.
Frequently Asked Questions
What size tank does a bearded dragon need?
An adult bearded dragon needs a 40-gallon breeder as an absolute minimum, but 75 to 120 gallons gives far better results. More floor space lets you build a true warm side and cool side, which is essential for a reptile that controls its body temperature by moving between zones. Babies can live in a large enclosure right away if you add clutter and sight lines. Never house two dragons together, since they are territorial and will fight.
How hot should a bearded dragon's basking spot be?
Aim for a basking surface of 95 to 110F, with juveniles toward the warmer end near 100 to 110F and adults a touch cooler. The cool side should sit around 75 to 85F so your dragon can move away from the heat. At night, most homes are fine without extra heat as long as the room stays above roughly 65F. Always confirm temperatures with a digital infrared thermometer rather than guessing.
Do bearded dragons really need UVB?
Yes, UVB is not optional. Bearded dragons use UVB to produce vitamin D3, which lets them absorb the calcium in their food. Without it they slowly develop metabolic bone disease, which causes soft bones, tremors, and deformity. Use a linear T5 HO 10.0 UVB bulb spanning most of the enclosure, mount it at the distance the maker specifies, and replace it every 6 to 12 months because output fades long before the light burns out.
What do bearded dragons eat?
Diet shifts with age. Babies and juveniles eat roughly 80 percent insects and 20 percent greens to fuel fast growth, while adults flip to about 80 percent greens and 20 percent insects. Good feeder insects include dubia roaches, crickets, black soldier fly larvae, and hornworms. Offer leafy greens like collard, mustard, and dandelion daily. Dust insects with calcium and gut load feeders before serving so your dragon gets the most nutrition.
What substrate is safe for a bearded dragon?
For beginners, solid substrates are safest. Reptile carpet, tile, or sealed surfaces are easy to clean and carry no impaction risk. Loose particle substrates like sand, walnut shell, or fine soil can be swallowed during feeding and pack the gut, a dangerous blockage called impaction. If you ever choose a naturalistic loose substrate, research it carefully and feed in a separate dish. When in doubt, keep it simple and solid.
How do I know if my bearded dragon is sick?
Watch for warning signs like refusing food for an extended period, sudden weight loss, sunken eyes, lethargy, black bearding paired with stress, swollen or bent limbs, tremors, runny stool, or labored breathing with open-mouth gasping that is not basking behavior. Stuck shed that constricts toes is also a concern. Bearded dragons hide illness well, so any lasting change deserves attention. For anything worrying, contact a reptile or exotic vet promptly.
How long do bearded dragons live?
With good husbandry, a bearded dragon typically lives 10 to 15 years, and some exceed that. Lifespan is largely in your hands. Correct UVB, proper basking and ambient temperatures, an age-appropriate diet with calcium, a roomy enclosure, and routine vet care all add years. Cutting corners on lighting or heat is the most common reason dragons fall short of their potential, so treat those basics as non-negotiable from day one.
