ProRep Coco Brick Coconut Fibre Substrate

ProRep Coco Brick is a compressed coconut fibre substrate suited to reptiles, amphibians, and invertebrates that require a humid vivarium environment. Available in two sizes to suit different enclosure setups, each brick expands on contact with water to produce a ready-to-use, natural-feeling bedding.

What It's Made From

Coco Brick is produced from the fibrous husk of the coconut — a natural by-product that is both sustainable and biodegradable. The husk is screened and ground to a consistent particle size before compression, resulting in a clean, dust-reduced substrate free from synthetic additives.

Why It Works for Humid Enclosures

The structure of coconut fibre holds moisture effectively, making it well suited to species that need elevated humidity levels in their terrarium. The substrate is slightly acidic by nature and carries high antibacterial properties, while a high lignin content means it resists breakdown even when kept damp — reducing the risk of unwanted microbial activity under moist conditions.

How to Use It

• Spread evenly across the enclosure floor to a depth of 2.5–5cm (1–2 inches)
• Can be used dry or moistened depending on the humidity requirements of your species
• Mist with water to maintain humidity as the substrate dries out — avoid waterlogging
• Spot clean daily, removing soiled areas and replacing with fresh substrate
• Can be used alone or blended with other substrates to suit specific setups
• Replace fully every two to three weeks, or sooner if heavily soiled

Suitable Species

ProRep Coco Brick is a practical choice for a wide range of humidity-loving species — including tropical reptiles, dart frogs, tree frogs, tarantulas, millipedes, and other invertebrates. Its natural composition makes it a safe option for bioactive-style setups as well as more straightforward terrarium builds.
