Complete Bearded Dragon Care Guide

Bearded dragons (Pogona vitticeps) are diurnal, medium-sized lizards native to Australia’s arid regions. They reach 18–24 inches as adults, are generally docile when housed correctly, and can live 10–15 years with proper care. Stress and shortened lifespan usually stem from inadequate enclosure size, weak UVB, or poor diet—all addressable with the standards in this guide.

The minimum for one adult is a 4×2×2 ft (48×24×24 in) enclosure—roughly 120 gallons. This length is required for a true temperature gradient, adequate UVB coverage, and space for basking, hides, and climbing. Older 40- or 75-gallon advice does not meet current standards; larger than 4×2×2 is acceptable and often preferred.

For step-by-step layout and hot/cool side setup, see our Bearded Dragon Tank Setup Guide. To generate a shopping list that enforces 4×2×2 and compatible equipment, use the builder below.

A hot basking zone (100–108°F surface temp, measured with a temp gun) and a cool side (mid-70s to low 80s °F) allow thermoregulation. Halogen floods or a ceramic heat emitter (CHE) are standard; every heat source must be on a thermostat to prevent burns and overheating.

UVB is non-negotiable: it drives vitamin D3 synthesis and calcium absorption. Without adequate UVB, bearded dragons develop metabolic bone disease (MBD). The standard is a T5 high-output 10.0 or 12% tube over roughly half the enclosure; coil bulbs are typically too weak or uneven. For placement, thermostats, and common lighting errors, see our Bearded Dragon Lighting & UVB Guide.

Beginners do well with solid options (paper towel, slate tile). A 50/50 topsoil and playsand mix suits naturalistic setups when husbandry is correct. Never use calcium sand, reptile carpet, or walnut shell—see our Bearded Dragon Substrate Guide for safe choices and what to avoid.

Provide at least two hides (warm and cool), a sturdy basking platform at the correct height for 100–108°F and UVB exposure, and climbing branches or cork. Plants (fake or safe live) add cover and reduce stress.

Bearded dragons are omnivores: staple insects (dubia, crickets, BSFL) and leafy greens (collard, mustard, dandelion, turnip, escarole, endive), sized no larger than the space between the eyes. Young dragons eat more insects; adults should get most calories from greens, with insects several times per week. Fruit is high in sugar—offer rarely if at all. For age-based schedules and supplementation, see our Bearded Dragon Feeding Guide.

Much of their water comes from food: fresh greens and well-hydrated insects. A shallow water bowl is still recommended; keep it shallow to prevent drowning. Dust insects with calcium (with D3 if UVB is weak or absent; without D3 with strong T5 UVB) at most feedings, and add a reptile multivitamin once or twice weekly. Over-supplementing is harmful—stick to a clear schedule.

Arm waving often signals submission or recognition; head bobbing is typically dominance or territorial. Glass surfing can indicate stress, an undersized enclosure, or reflection. Black beard and body flattening may signal stress or illness. Knowing normal behavior makes it easier to spot when something is wrong.

Frequent errors: enclosure too small (e.g. 40 gal), weak or no UVB, unregulated heat, measuring air temp instead of basking surface, calcium sand, reptile carpet, adults fed only insects, and skipped supplements. “Starter kits” often include undersized tanks and inadequate UVB—verify every item against the standards above.
