ProRep Coco Brick

ProRep Coco Brick is a compressed coconut fibre substrate designed for reptiles, amphibians, and invertebrates that require a humid vivarium environment. Made from the fibrous husk of the coconut, it is 100% natural, sustainably sourced, and suitable for a wide range of tropical and moisture-dependent species. Available in multiple sizes to suit enclosures of different scale.

What It's Made From

The fibre is sourced from the outer husk of the coconut, which is screened and ground to an appropriate particle size before compression into brick form. The result is a slightly acidic substrate with high antibacterial properties and a naturally high lignin content, which helps resist rotting even when kept moist — making it well suited to humid setups that require regular spraying.

Humidity Retention

Coco Brick absorbs and holds moisture effectively, allowing keepers to maintain consistent humidity levels across the enclosure. As the substrate dries out it can be misted to restore the required moisture level, and it can be used wet or dry depending on the needs of the species being kept. Avoid over-saturating to the point of waterlogging.

How to Use It

• Expand the brick in water, then spread evenly across the enclosure floor
• Use alone or blend with other substrates to suit your setup
• Spot clean daily by removing soiled areas and replacing with fresh material
• Replace the full substrate every two to three weeks, or sooner if heavily soiled
• Mist as needed to maintain target humidity without waterlogging

Species Suitability

ProRep Coco Brick is appropriate for tropical reptiles, tree frogs, dart frogs, burrowing invertebrates, and other species that benefit from a moist, naturalistic substrate. Its natural composition makes it a safe choice across a broad range of taxa kept by UK reptile and invertebrate enthusiasts.

Available in a range of sizes, ProRep Coco Brick scales from smaller vivariums and quarantine tubs through to larger tropical enclosures — choose the size that suits your setup from the options on this page.
