Bearded Dragon Vivarium Setup: A practical Guide

Bearded Dragons are one of the most rewarding reptiles you can keep. They are active, personable and respond well to their owners. But they do need the right setup to thrive. Get the vivarium right and everything else follows.

We will cover all the essentials that you need to know about keeping your reptile including size, material, heating, lighting and layout.

 

What Size Vivarium Does a Bearded Dragon Need?

Adult bearded dragons need space. A 4ft vivarium (120x60x60cm) is the widely accepted minimum for an adult. A 4ft setup is practical and a popular starting point, it suits a number of other species too if your collection grows. Or guide on what can live in a 4ft vivarium covers the options in detail.

Juveniles can start in a 3ft enclosure. A smaller space makes it easier for them to locate food and feel secure, and overly large enclosures can cause stress in very young animals. However, they do grow rapidly in the first 12 months and will outgrow a 3ft setup quickly. Buying the adult size from the start and using a divider to reduce the usable space temporarily is a good approach that saves money on a second enclosure later.

Do not house bearded dragons together. Males will fight and even females kept together can develop dominant and submissive dynamics that lead to stress and uneven feeding.

 

Vivarium Material: PVC or Wood?

Bearded dragons have significant heat requirements. Their basking spot needs to reach 35-40 degrees Celsius, and the enclosure needs to hold that heat efficiently throughout the day. The material your vivarium is made from directly affects how well it does that.

Wood absorbs moisture which can become a problem if you are misting the enclosure, cleaning up liquid waste or running a bioactive setup. Over time it can warp, swell and hold harbour bacteria that is hard to shift.

PVC holds its shape and doesn’t absorb water and can retain heat well. Our PVC vivarium’s are made from 10mm foam PVC with 4mm toughened glass. They are UV resistant, self-extinguishing and easy to clean. If you want a proper comparison between the two materials, you can read our article on PVC vivarium’s vs wooden vivarium’s.

 

Heating

Bearded dragons are sun-baskers. They need a clear thermal gradient across the vivarium, with a hot basking spot at one end and a cooler at the other.

·         Basking spot- 35-40 degrees Celsius

·         Warm side ambient 25-28 degrees Celsius

·         Cool side ambient 25-28 degrees Celsius

·         Nighttime should be no lower than 18 degrees Celsius

Use a halogen basking bulb positioned above a flat rock or raised platform at one end of the vivarium. Run it through a thermostat set to your target temperature. Don’t guess the temperatures. A decent thermometer with a probe at basking point and cool end is essential.

Under-tank heat mats are not suitable as the primary heat source for bearded dragons. They do not generate the surface temperatures needed and are less effective for a species that basks from above.

 

UVB Lighting

This is non-negotiable. Bearded dragons need strong UVB to synthesise vitamin D3 and absorb calcium properly. Without it they develop metabolic bone disease, which is painful, progressive and preventable.

A T5 HO UVB tube covering at least two thirds of the vivarium length is the standard recommendation. A 12% D3+ is widely used and well suited to bearded dragons. Replace the tube every 12 months even if it still appears to produce light, as UVB output degrades before visible light does.

Run the UVB on a 12-to-14-hour cycle in summer and 10 to 12 hours in winter to mimic natural light patterns.

 

Substrate

Adults kept in well-managed setups do well on a sad and soil mix, which allows for natural digging behaviour. Bioactive setups are increasingly popular for bearded dragons and work well in PVC enclosures where moisture can be managed properly.

Avoid play sand alone. It compacts and can cause impaction. A 60/40 or 70/30 mix of organic topsoil to reptile sand is a better base.

 

Layout

Bearded dragons are active and curious. Give them room to move and things to interact with. A raised basking platform at the warm end, a hide or a cave at the cool end. Between the two ends add some flat rocks, cork bark and low branches that the dragon can climb onto and explore.

 Keep pathways clear between the basking spot and the cool end so the dragon can move freely across the thermal gradient without obstacles. Overcrowding the vivarium reduces its effectiveness as a thermal environment.

Clean the vivarium thoroughly every four to six weeks, removing all substrate and decorations and disinfecting the interior. Spot clean daily waste as a clean vivarium is a fundamental part of keeping a healthy animal.
