How to Set Up a Bearded Dragon Tank: NZ Beginner's Guide

The quick answer: a bearded dragon needs a large enclosure with a proper temperature gradient (a hot basking end and a cooler end), correct UVB lighting, and the right humidity — get these wrong and the dragon gets sick, no matter how good the food is. Set the habitat up fully and check the temperatures with thermometers *before* the dragon comes home.

Enclosure size

Bigger is better. An adult bearded dragon needs a large enclosure — think around 120 cm (4 ft) long as a practical minimum for one adult, larger if you can. Babies can be kept in something smaller but grow fast, so many keepers buy adult-size from the start.

Heat and the temperature gradient

Beardies are desert reptiles that thermoregulate by moving between hot and cool areas:

• Basking spot: a hot surface around 38–41°C (about 100–105°F) for adults, a little warmer for babies, created with a basking lamp. Measure the basking *surface*, not just the air.
• Cool end: around 24–29°C (about 75–85°F), so the dragon can move away from the heat.
• Night: can drop cooler. Use thermostats and a couple of thermometers (one at each end) to verify — never guess.
• Provide a basking platform/branch under the lamp.

UVB lighting (essential)

Bearded dragons must have UVB light to produce vitamin D3 and use calcium; without it they develop metabolic bone disease. Use a quality UVB tube across much of the enclosure, replace it on schedule (UVB output fades before the light looks dead), and don't filter it through glass/plastic.

Substrate, decor and water

• Substrate: for beginners, solid options (reptile carpet, tile, or paper) avoid the impaction risk loose sand can pose, especially for young dragons.
• Decor: branches and a hide at both ends so the dragon feels secure and can climb/bask.
• Water: a shallow dish; beardies also get moisture from food.

Before the dragon arrives

Run the full setup for a few days and confirm both ends hold the right temperatures and the UVB is working. Then feed correctly — see what do bearded dragons eat in NZ.

Quick takeaways

• Large enclosure (~120 cm+ for an adult) with a hot basking end and a cool end.
• Verify temps with thermostats and thermometers — don't guess.
• UVB lighting is essential; replace tubes on schedule, no glass in between.
• Use solid substrate for beginners to avoid impaction; hides at both ends.
• Set up and test the habitat before bringing the dragon home.
