The enclosure

2.1Size

Minimum 4 ft × 2 ft × 2 ft, whatever the age or size of the animal. Bigger is better and they will use every inch you give them.

This isn’t only about room to move. The 4×2×2 minimum is what makes the lighting work. You need the length for a genuine warm end and cool end, and the height to set correct UVB and basking distances. A dragon that basks all day is often one with nowhere else worth going.

2.2Substrate

Start solid. Move to loose once your husbandry is dialled in.

Loose substrate is better in the long run. It lets them dig, it’s closer to what they evolved on, and it’s easier to clean because waste clumps like cat litter instead of smearing. It also punishes mistakes. Get lighting, temperatures and humidity right first, then switch.

Safe solid substrates

• , Paper towel
• , Non-adhesive ceramic tile
• , Non-adhesive shelf liner, food-grade
• , Silicone mat, food-grade
• , Non-adhesive slate
• , a textured silicone mat

Safe loose substrates

• , 50/50 organic topsoil or coir and children’s play sand
• , 50/30/20 children’s play sand, organic topsoil or coir, and excavator-type burrowing clay
• , a ready-mixed arid bioactive substrate
• , a screened natural desert-habitat substrate

Digging and dig boxes

Digging is a natural behavior for bearded dragons and can be encouraged once your dragon is established, healthy, and has appropriate husbandry. If you are starting with a solid substrate (such as tile, paper, or shelf liner) and want to introduce digging, this can be done gradually by adding a dedicated dig area inside the enclosure or by offering a separate supervised dig box outside the enclosure.

2.3Decor and enrichment

Natural materials work best. Wood, rock, live plants.

Avoid furnishing the enclosure with doll house furniture, blankets and soft toys. It photographs well and gives the dragon nothing to do, and boredom is one of the reasons a dragon sits under the lamp all day.

2.4Safe plants

Aloe (all species) · Agave · Tillandsia air plants (all species) · Spineless cactus (Opuntia) · Echeveria · Haworthia · Rosemary · Lithops · Cryptanthus · Gasteria · Portulacaria · Ponytail palm · Sage · Wheatgrass · Jade

2.5The basking surface

Any roughly flat surface the whole animal fits on, which you can raise and lower to set the right distance to the UVB.

Almost any material works. The exceptions are some plastics, which off-gas VOCs, and coniferous and eucalyptus woods.

You don’t need slate

Slate and stone are fine but they aren’t the only option, despite how often they’re recommended. Flat cork bark, a wide log, a piece of hardwood, bricks, a large tile all work.

Lighter colors are safer. Black slate gets too hot to touch at the infrared level that is otherwise correct, so it will burn a dragon in a setup where everything else is right. Lighter natural slate, flagstone, cork bark, tile, wood, sandstone and pavers behave better. This is the same effect that makes temperature guns unreliable, covered in 3.4.

Radiative heat from stone

Some warmth radiating up from rock is pleasant once the lights are off, but it isn’t necessary. Bearded dragons are heliothermic. They take what they need from the lamp above, not the rock below.

The surface has to be wide and flat enough for the dragon to lie flat under the basking bulb and the UVB at the same time. Too narrow and it only ever gets one of them. Angled lights can make a narrower surface workable.
