Exo Terra Rock Background 18 x 18" Suits EGT03

• Moulded rock texture – a genuine three-dimensional rock face, not a printed pattern.
• Deep ridges – conceal wiring, tubing and heat cord runs behind the scape.
• Black polystyrene construction – scuffs and scratches from claws or décor are far less visible than on a lighter background.
• Insulating layer – sits against the rear glass and takes the edge off heat and humidity loss through that panel.
• Cuts to size – trim with scissors or a craft knife for a custom fit.

Sized for the Exo Terra Small Wide Terrarium (45 × 45 × 45 cm), whose rear glass is 45 cm wide by 45 cm high – a factory fit with no trimming needed. Setting it up in a different terrarium? Check the size table below first.

All five Exo Terra Rock Backgrounds are cut to match a specific Exo Terra Natural Terrarium. Measure your terrarium's rear glass panel – width × height – and match it against the model below.

Backgrounds can be trimmed down with scissors or a craft knife for a smaller footprint, but they can't be stretched to cover a larger one – when in doubt, size up rather than down.

One 45 × 45 cm rock-effect background panel. Silicone sealant to mount it, and the terrarium itself, are sold separately.

• Suitable for terrestrial and arboreal reptiles and amphibians, and both tropical and desert terrarium styles.
• Not suitable for permanent submersion – this is a terrarium backdrop, not a rated aquatic or paludarium liner, and it hasn't been tested below the waterline.

Wipe down with a damp cloth. Avoid solvents or abrasive cleaners, which can degrade the polystyrene coating. The textured ridges can trap loose substrate and debris – rinse or vacuum them out occasionally as part of your normal enclosure clean.

The panel is non-toxic and safe for contact with reptiles and amphibians. Keep heat sources such as ceramic heat emitters and heat mats at the manufacturer's recommended clearance from the panel – polystyrene is heat-sensitive and can warp or scorch if a fixture is mounted too close.

• Zoo Med Creatures Digital Thermometer – an easy way to spot-check basking and cool zones once the new background is installed.
• EcoTech Analog Hygrometer Thermometer – check that the added insulation from the background hasn't pushed temperature or humidity outside your target range.
• Zoo Med Repti Bark Chips – a natural-toned substrate that sits well against the rock-effect backdrop.

Covered by Nick's Aquarium Oceanarium Terrarium's standard returns policy for change-of-mind and damaged-on-arrival items, in addition to your rights under Australian Consumer Law – contact us before returning a panel that's already been trimmed or fitted. Ships as a standard parcel; no oversize or dangerous goods handling applies.

Does this fit the Small Low terrarium as well?

No – the Small Low (45 × 45 × 30 cm) has a shorter rear glass than the Small Wide this panel is cut for. You'd need to trim roughly 15 cm off the height, which is easy to do but worth measuring first.

Is the square shape symmetrical, so it doesn't matter which way up I fit it?

The rock texture has a directional grain, so we'd suggest checking the ridge pattern before committing to a mounting orientation – once silicone cures, repositioning means starting again.

What do I use to stick it to the glass?

A 100% aquarium-safe silicone sealant, applied in a bead pattern to the back of the panel before pressing it into place. Silicone isn't included with the background.

Will it change the humidity in my terrarium?

Not on its own. It adds a small amount of insulation to the rear glass but doesn't replace your normal misting, ventilation or humidity gradient setup.
