Bearded Dragon Husbandry Guide

Practical, species-specific husbandry for Pogona vitticeps: enclosure, UVB, basking temps, age-based diet progression, and safe brumation steps.

Introduction

Bearded dragons (Pogona vitticeps) are one of the most commonly kept pet lizards because of their calm temperament and relatively straightforward care — but “straightforward” doesn’t mean careless. This guide provides breed-specific, practical instructions for UVB lighting, precise basking temperatures, age-appropriate diet progression, and step-by-step brumation management. Follow these steps to keep your dragon healthy, active, and long-lived.

Breed-specific considerations

• Bearded dragons are desert/woodland generalists: they require strong UVB, a pronounced thermal gradient, and a diet that shifts from insect-heavy when young to mostly plant-based as adults.
• They continue growing into their second year and reach sexual maturity around 12–18 months. Husbandry must change with age (see Diet by Age).
• Pogona are diurnal (active in daylight) and rely on UVB for vitamin D3 synthesis and calcium metabolism; inadequate UVB is the most common cause of metabolic bone disease (MBD).

Enclosure: sizes, layout, and substrate

• Hatchling/juvenile (0–6 months): 20–40 gallon long tank. Provide climbing branches and low hiding spots.
• Juvenile/subadult (6–12 months): 40–75 gallon long or a 3–4 ft long vivarium.
• Adult (12+ months): Minimum recommended enclosure is a 4 ft (120 cm) long tank (75–120 gallon). Bigger is better to allow thermoregulation and exercise.

• Safe: reptile carpet, ceramic/porcelain tile, paper towel (temporary), slate.
• Avoid loose particulate substrates (calcium sand, walnut shells, loose sand) for young dragons — impaction risk.

• Basking platform/rock and horizontal branches for climbing
• Multiple hides (warm and cool)
• Shallow water dish (large enough to soak but not deep)
• Digital probe thermometer(s) and infrared surface thermometer
• Hygrometer
• UV index meter (radiometer) if possible

Heating and lighting (UVB and basking)

Bearded dragons need a clear, measurable thermal gradient and strong, reliable UVB.

Basking temperatures (target):

• Hatchlings/juveniles (0–6 months): 100–110°F (38–43°C) at the basking surface
• Juveniles/subadults (6–12 months): 95–105°F (35–40°C)
• Adults (12+ months): 95–100°F (35–38°C)

UVB lighting (practical guidance):

• Use a full-spectrum T5 high-output (HO) fluorescent tube or a quality linear UVB tube designed for reptiles. These provide even UVB across the enclosure and are the preferred option for bearded dragons.
• Mercury vapor bulbs (MVB) that provide heat and UVB are an option for larger enclosures, but follow manufacturer distance recommendations carefully to avoid burns.
• Position: no glass or screen between the dragon and the UVB bulb. If lamps must be outside the tank, pick ones rated to penetrate screen mesh and measure the UV index.
• Replace fluorescent UVB bulbs every 6–12 months (manufacturer guidance varies). Even if the bulb looks bright, UV output declines with age.
• Aim for a daytime UV Index (UVI) of about 3–6 in the basking zone (measure with a UVI meter). If you don’t have a meter, follow manufacturer distance recommendations and use a quality T5 HO tube suspended close (but not touching) the basking area.

Diet: progression by age (step-by-step feeding schedule)

Diet must change over time as bearded dragons shift from insectivory to omnivory.

Hatchling (0–4 months):

• Daily frequency: Offer insects 2–3 times per day, multiple small feedings.
• Composition: ~70–80% insects (appropriately sized), 20–30% finely chopped safe greens and veggies.
• Insect size: no larger than the space between the dragon’s eyes (usually < 1/4 inch for very small hatchlings).
• Supplements: Dust feeders with calcium powder (without D3) at most feedings. Offer a multivitamin with D3 once per week.

• Daily frequency: Feed insects 1–2 times per day, still daily greens offered.
• Composition: Move to ~50–60% insects, 40–50% greens/vegetables as the months progress.
• Supplements: Calcium (no D3) 3–5 times per week; multivitamin once per week.

• Frequency: Insects once daily or every other day; greens daily.
• Composition: ~30–40% insects, 60–70% plant matter.
• Supplements: Calcium 2–3x per week; multivitamin once per week.

• Frequency: Offer a variety of leafy greens and vegetables daily; insects 2–4 times per week as treats/protein.
• Composition: ~70–80% vegetables/greens, 20–30% insects.
• Supplements: Calcium 2–3x per week, multivitamin weekly. If you have consistent, correct UVB exposure, D3 supplementation should be used sparingly and under vet guidance.

Insect advice (gut-loading and safety):

• Use gut-loaded crickets, dubia roaches, black soldier fly larvae, or phoenix worms. Gut-load for 24–48 hours with nutrient-rich food.
• Avoid wild-caught insects (parasites, pesticides). Avoid fireflies and some beetles (toxic).

• Continuing a high-insect diet for adults → obesity and nutritional imbalance.
• Using loose sand or small substrate that leads to impaction.
• Not gut-loading feeder insects or failing to dust appropriately with calcium.

Brumation (seasonal dormancy): when and how to manage it safely

Many bearded dragons brumate (a reptilian winter dormancy) once sexually mature or after a stressful season. Brumation can be normal, but it must be managed carefully.

When to consider brumation: reduced appetite, less activity, more time hiding, and reduced basking. Before allowing brumation, confirm health.

Step-by-step brumation management

Common brumation mistakes

• Allowing a sick or underweight dragon to brumate without vet clearance.
• Rapid temperature drops causing stress or respiratory infections.
• Not monitoring weight and hydration during brumation.

Husbandry maintenance schedule (frequency recommendations)

• Daily: spot-clean feces, refresh water, observe behavior and appetite, check temps.
• Weekly: change substrate spots as needed, clean food/water dishes, weigh your dragon for growth/weight loss tracking.
• Monthly: deep-clean parts of the enclosure (remove decor, wash with reptile-safe disinfectant), replace substrate if necessary.
• Every 6–12 months: replace UVB bulbs and batteries in monitoring devices; have a fecal parasite check annually or if you notice abnormal stools.

Common mistakes owners make (summary)

• Inadequate UVB or using the wrong bulb type/distance
• Too small enclosures for adult dragons
• Over-reliance on insects for adult diet leading to obesity
• Unsafe substrates (impaction risk)
• Ignoring smell/behavior changes (delaying vet visits)
• Improper brumation without vet screening

Signs of problems — when to seek a reptile veterinarian

Seek immediate veterinary attention if you see:

• Severe or progressive weight loss (>10% body weight)
• Lethargy, refusal to right itself, or collapse
• Swollen limbs, jaw, or soft/twisted toes (possible metabolic bone disease)
• Difficulty breathing, wheezing, discharge from nose/mouth (respiratory infection)
• Bloody or very loose stool, green runny stool, or lack of feces for several days (impaction)
• Persistent eye problems or retained shed
• Visible wounds, ulceration, or discolored skin

Product recommendations (generic categories)

• Lighting: T5 high-output UVB linear tubes (desert reptile rating) and reliable fixtures
• Supplemental heat: ceramic heat emitter or basking halogen bulbs and a thermostat for ceramic emitters
• Monitoring: digital probe thermometer(s), infrared surface thermometer, hygrometer, UV index (UVI) meter
• Substrate: ceramic tile, reptile carpet, or large-format slate
• Feeding aids: digital kitchen scale for portioning, tongs for safe insect offerings
• Hygiene: reptile-safe disinfectant, soft-bristled brush for shedding issues

Key takeaways

• Bearded dragons require strong, consistent UVB (T5 HO preferred) and a clear thermal gradient with precise basking temps (95–110°F depending on age).
• Diet must change with age: hatchlings are insect-heavy; adults should be mostly varied leafy greens and vegetables.
• Safe substrate, proper enclosure size, and routine monitoring (weights, temps, hydration) prevent the most common problems.
• Brumation can be normal, but always vet-check first, drop temperatures gradually, and monitor weight and hydration weekly.
• Seek a reptile-experienced veterinarian promptly for signs of MBD, respiratory disease, impaction, or significant weight loss.
