Bearded dragon care guide

Pogona vitticeps

A large, highly active desert lizard with one of the highest UVB requirements in the hobby. 40-gallon tanks are a starting point, not an adult home.

Terrestrial — floor space first

Bearded dragon enclosure size

Terrestrial — floor space first. An adult bearded dragon should live in at least 48" L × 24" W × 24" H; we build toward 96" L × 24" W × 24" H (8 × 2 × 2 ft, roughly 16 sq ft of floor and about a 239-gallon glass equivalent).

4x2x2 is the floor; 6–8ft long is where they thrive. Never house two together.

Hatchling / baby
48" L × 24" W × 24" H recommended · min 36" L × 18" W × 18" H
Juvenile
72" L × 24" W × 24" H recommended · min 48" L × 24" W × 24" H
Adult
96" L × 24" W × 24" H recommended · min 48" L × 24" W × 24" H

Temperature and heating

Cluster of halogen flood bulbs over a raised basking platform, on a dimming thermostat.

Basking / warm surface
100–107°F surface for adults (105–110°F for babies)
Warm side (ambient)
85–95°F ambient
Cool side (ambient)
75–85°F ambient
Night
65–75°F

Lighting and UVB

UVB: Linear T5 UVB 10–12% spanning ~2/3 of the enclosure (UVI 4–6 at basking). Run lights on a 12–14 hours photoperiod, on a timer, and replace UVB bulbs on the manufacturer's schedule even while they still emit visible light.

Humidity

Target 30–40%. Dry enclosure, water bowl only; high humidity causes respiratory infection.

Substrate and depth

Topsoil / play sand mix (bioactive friendly). Depth: 4 in.

Enclosure tips and furnishing

  • Raised basking rock or platform under the lamp
  • Hide on the cool end
  • Branches for climbing
  • Water bowl and open sight-lines

Build list

  • 4x2x2 minimum enclosure (6ft preferred) — Beardies patrol constantly and need a huge gradient.
  • Linear T5 10–12% UVB fixture — Highest-UVB pet species; compact coil bulbs are not adequate.
  • Halogen flood bulbs + dimming thermostat — Wide, hot basking surface rather than a hotspot.
  • Digital thermostat — Every heat source must run through a thermostat — unregulated heat burns animals.
  • Two digital probe thermometers + hygrometer — Read the warm side, cool side and humidity directly — stick-on dials are inaccurate.
  • Bulk topsoil/sand mix — Diggable and dust-free at 4in depth.
