WIO Nano Rocks - Ryuoh

WIO Ryuoh Nano Stone brings the language of mountains — jagged faces, deep cuts, and pale mineral veins — to nano scale, perfectly sized for Iwagumi compositions and detailed highland scapes in tanks under 40L.

Ryuoh Nano Stone carries the same iconic jagged character as the full-size Ryuoh Stone — fractured planes, stepped ridges, and glowing pale quartz veins against deep grey calcareous limestone. Place a single piece and the nano scape sharpens instantly; compose a full arrangement and you get a convincing miniature cliff landscape with silhouettes that photograph beautifully. Under light the veins glow; between pieces shadows pool for scale and depth.

Sized between 3 and 10 cm, ideal for nano tanks under 40L. As a calcareous limestone, Ryuoh may gently raise pH and hardness over time; routine water changes keep parameters steady. Pre-washed and ready to use.
