Ryuoh Boulder Nano Stone is a river-shaped of the traditional Ryuoh stone-one of aquascaping’s most recognizable and beloved materials. Naturally rounded and softened by water erosion, each piece features a deep grey base tone with flowing white veins and smooth mineral transitions. The surface is polished by nature, offering a tactile, organic presence that contrasts beautifully with plants and driftwood.

Sized between 3 and 10 cm, these boulders are ideal for tanks under 40 L, allowing you to build expressive, compact hardscapes with natural flow and rhythm. Their neutral composition ensures they won’t alter pH or water hardness, making them safe for all aquatic life, including shrimp.
