A stronger alternative to exposed foam
A realistic rock wall built for everyday terrarium life
The standard foam insert can mark, chip or expose its core over time. Aqua Maniac uses poly-resin to create a more substantial decorative wall with crisp rock, root and stone detail.
- Hard to scratch under normal terrarium use
- Water-resistant and heat-resistant material
- Textured relief adds natural-looking depth and grip
- Handcrafted and hand-painted in small batches
- Suitable for tropical, woodland and arid visual themes
Choose the depth and finish that suits your setup
All three designs use tough poly-resin, but they create different visual weight and use different amounts of internal space.
Amazon Design
A deep brown root-and-rock relief, approximately 4–6 cm thick, for a dramatic forest-floor appearance.
Thin Beige Rock
A slim, layered stone finish in warm beige, approximately 2 cm thick, for a lighter naturalistic display.
Thin Grey Rock
The same space-saving profile in grey, approximately 2 cm thick, for cooler-toned rock and planted layouts.


Exo Terra background size chart
Match the model name and all three vivarium measurements before ordering. The background panel covers the rear wall, so its listed panel size is width × height rather than the full enclosure footprint.

Straightforward installation
Flat at the back, detailed at the front
The rear of each panel sits flat against the terrarium glass. Dry-fit first, then use silicone suitable for terrarium use and seal the edges carefully. A properly fitted perimeter prevents crickets and other feeder insects from finding an open route behind the background.
Choose the slim 2 cm rock designs where internal space matters most, or the deeper Amazon Design when pronounced relief is the priority.

Exo Terra 3D background FAQs
Are these backgrounds made by Exo Terra?
No. They are designed and made by Aqua Maniac to fit the listed Exo Terra terrarium models. Aqua Maniac is independent and is not affiliated with Exo Terra.
How are Aqua Maniac backgrounds different from the original foam insert?
Aqua Maniac backgrounds are made from hard poly-resin rather than exposed polystyrene foam. They are hard to scratch, water-resistant and heat-resistant, with a detailed hand-finished surface.
Can crickets hide behind the background?
The panel has a flat back. When it is fitted against the rear glass and the perimeter is properly sealed with suitable silicone, there is no open cavity behind it for feeder insects to enter.
Which design saves the most space inside the terrarium?
Thin Beige Rock and Thin Grey Rock are approximately 2 cm deep, so they preserve more usable enclosure space. Amazon Design has deeper relief of approximately 4–6 cm for a more dramatic root-and-rock effect.
How do I install a 3D terrarium background?
Dry-fit the panel first, clean and dry the glass, then bond and seal the flat rear face with a silicone suitable for terrarium use. Allow it to cure fully according to the silicone manufacturer’s instructions before adding animals.
Can I use one with a bearded dragon, gecko, snake or frog?
The background is a decorative enclosure component used in many reptile and amphibian setups. Always plan heat, humidity, ventilation and furnishings around the needs of your particular species.
What if my enclosure is not one of the listed Exo Terra sizes?
Use Aqua Maniac’s made-to-measure service for a background produced for your enclosure dimensions rather than ordering the nearest standard size.
