Bearded dragon care guide for beginners: learn the right tank size, UVB lighting, basking temperature, diet, and handling tips for a healthy pet.
Bearded dragons are among the friendliest and most popular pet lizards. They are calm, curious, and usually tolerate gentle handling, which makes them a favorite for first-time reptile keepers. They are also long-lived, often reaching 10 to 15 years, and they need a carefully built setup with the right heat and lighting. This guide covers everything you need to know to get started.
Are Bearded Dragons Good Pets for Beginners?
Yes, with some preparation. Bearded dragons are active during the day, easy to feed, and often enjoy interacting with people. At the same time, they need a large enclosure, strong heat and UVB lighting, a steady supply of live insects, and fresh vegetables every day. Think of the setup as a significant, long-term investment.
Bearded Dragon Tank Size
A baby can start in a smaller enclosure, but it will grow quickly, so it's often more economical to buy the adult size from the start. A single adult needs at least a 120-gallon enclosure, roughly 4 feet long, 2 feet wide, and 2 feet tall (about 120 x 60 x 60 cm). Larger is better. Choose an enclosure with a secure lid, good ventilation, and front-opening doors if possible. Keep one dragon per enclosure, since they are solitary and housing them together can lead to stress and injuries.
Temperature and Basking Spot
Bearded dragons come from hot, dry regions and need a temperature gradient so they can warm up or cool down:
- Basking spot surface temperature: about 100 to 110°F (38 to 43°C) for adults, and slightly warmer, around 105 to 110°F (40 to 43°C), for babies and juveniles
- Cool side: about 75 to 85°F (24 to 29°C)
- Night: about 65 to 75°F (18 to 24°C), usually with no extra heat unless the room drops lower
Use a basking lamp on one side of the enclosure, and measure the surface temperature with an infrared thermometer, along with digital thermometers on the warm and cool sides. A thermostat or dimmer helps prevent overheating.
UVB Lighting Is Essential
Bearded dragons need UVB light to make vitamin D3 and absorb calcium. Without it, they can develop metabolic bone disease, a painful and potentially fatal condition. Use a reptile UVB tube made for desert species, mounted at the distance recommended by the manufacturer, and keep it on for about 10 to 12 hours a day. UVB output fades over time, so replace the bulb every 6 to 12 months, or as the product directs, even if it still shines. Glass and plastic block UVB, so sunlight through a window does not count.
Best Substrate for Bearded Dragons
Safe, easy-to-clean choices include ceramic tile, reptile carpet, and paper towels, especially for babies. Loose substrates such as sand and crushed walnut shell can cause impaction if swallowed, so many keepers avoid them for young dragons. Spot clean daily and disinfect the enclosure regularly with a reptile-safe cleaner.
Hides, Climbing Spots, and Decor
Provide a hide on the cool side so your dragon can retreat and rest. Add sturdy branches, rocks, and platforms for climbing and basking, and make sure everything is stable and has no sharp edges. Dragons enjoy a place to climb that puts them closer to the heat source.
What Do Bearded Dragons Eat?
Bearded dragons are omnivores, and their diet changes with age:
- Babies and juveniles: mostly insects, roughly 70 to 80 percent, with fresh greens making up the rest
- Adults: mostly plants, roughly 70 to 80 percent, with insects making up the rest
Good staple insects include dubia roaches, crickets, and black soldier fly larvae. Hornworms and silkworms make good occasional treats. Choose insects no larger than the space between your dragon's eyes, and never feed wild-caught insects, which may carry parasites or pesticides. Feed the insects a nutritious diet before offering them, which is known as gut-loading.
Best Greens and Vegetables
- Collard greens, mustard greens, turnip greens, and dandelion greens
- Butternut squash and other soft squash
- Bell pepper, green beans, and bok choy in moderation
- Small amounts of fruit, such as berries or papaya, as occasional treats
Spinach, kale, and beet greens should be limited, since they can interfere with calcium absorption when fed often. Finely chop everything to make it easy to eat, and remove leftovers each day.
Foods Bearded Dragons Should Not Eat
- Fireflies: They are highly toxic to bearded dragons.
- Avocado and rhubarb: Both are considered toxic.
- Iceberg lettuce: It has little nutrition and can cause loose stool.
- Wild-caught insects: They can carry parasites or pesticides.
- Processed human foods, dairy, and anything sugary or salty
Calcium and Vitamin Supplements
Dust insects and greens with calcium powder and a reptile multivitamin on a schedule your vet recommends. Some keepers use calcium with vitamin D3 only a few times a week when good UVB lighting is in place, and plain calcium on other days. Follow the product label and ask a reptile veterinarian for a plan that fits your dragon's age and setup.
How Often to Feed a Bearded Dragon
| Age | Insects | Greens |
|---|---|---|
| Babies and juveniles | Several times a day | Offer daily |
| Adults | A few times a week | Daily |
Feed insects only as much as your dragon can eat in about 10 to 15 minutes. Offer a shallow dish of fresh water, and mist greens lightly. Many dragons drink little from a bowl, so occasional baths in shallow, lukewarm water can help with hydration.

Understanding Bearded Dragon Body Language
- Head bobbing: Often a sign of dominance or courtship.
- Arm waving: Usually a friendly or submissive signal.
- Black or darkened beard: Can signal stress, fear, or anger.
- Puffed-out beard: A defensive display.
- Mouth open while basking: Often just a way to release heat, but if it happens constantly, check your temperatures.
How to Handle a Bearded Dragon
Let your new dragon settle in for about a week before handling. Approach from the side, not from above, and scoop it up with both hands, supporting the whole body. Keep early sessions short and calm. Wash your hands before and after handling, since reptiles can carry Salmonella.
Shedding and Brumation
Dragons shed their skin in patches, and young dragons shed frequently as they grow. Don't pull stuck skin, but ask a vet for help if shed remains around the toes or tail tip. Adults may also go through brumation, a period of reduced activity and appetite that resembles hibernation, often in cooler months. If your dragon is sluggish or stops eating, check temperatures and lighting first, and see a vet to rule out illness.
Common Health Problems
See a reptile veterinarian if you notice any of these signs:
- Tremors, weak limbs, or a soft jaw, which can point to metabolic bone disease
- Bloating, no droppings, or trouble moving the back legs, which can suggest impaction
- Swollen or sore mouth, or discharge, which can signal mouth rot
- Weight loss, lethargy, or loss of appetite that continues
- Runny or foul-smelling droppings
Frequently Asked Questions
How big do bearded dragons get?
Adults commonly reach about 16 to 24 inches (40 to 60 cm) long, including the tail.
Do bearded dragons bite?
Bites are uncommon, especially with regular gentle handling. A stressed or hungry dragon may nip, so handle it calmly and wash your hands after handling food.
Can bearded dragons live together?
It's safest to house them separately. They are solitary and may fight, which can cause injuries.
Do bearded dragons need a heat lamp at night?
Usually not, as long as the room stays above about 65°F (18°C). If it gets colder, use a safe, non-light heat source, such as a ceramic heat emitter on a thermostat.
How long do bearded dragons live?
With good care, most live about 10 to 15 years.
Final Thoughts
Good bearded dragon care starts with the right enclosure, strong UVB lighting, a proper basking spot, and a diet of insects and fresh greens. Set everything up before you bring your dragon home, handle it gently, and find a reptile-savvy vet. A well-cared-for dragon makes a rewarding companion for more than a decade.
