WIO Druid Boulder Stone Kit is a high-impact choice for creating stunning aquascapes and terrariums. Textured and dark, these boulders are perfect for creating an aged, primordial atmosphere — ideal for stream biotopes and Ryoboku layouts alike.

The highly detailed texture of Druid Boulder makes it an ideal support for mosses and epiphytic plants, creating a natural-looking environment for your aquatic inhabitants. Druid Boulders are made of volcanic igneous rock, with irregular forms and holes that add to their natural appearance. Their dark, worn features add a hint of the primordial to any display.

As an inert stone, Druid Boulder does not affect water hardness, making it a safe and easy choice for your aquarium or terrarium. Its high porosity also gives it excellent water retention, making it an ideal choice for humid terrariums and paludariums.
