WIO Nano Rocks - Ryuoh

Ryuoh Nano Stone is a scaled-down version of the legendary Ryuoh Stone, revered in aquascaping for its dramatic structure and expressive texture. Named after the mythical Dragon King (“Ryu-oh” in Japanese), this limestone features sharp ridges, deep cuts, and a layered grey palette that recalls ancient mountain cliffs sculpted by time. Its natural surface complexity and pale veins offer contrast and visual tension, making it ideal for bold compositions in nano tanks under 40 L. Whether used as a standalone layout in an Iwagumi design or as an accent in larger hardscapes, Ryuoh Nano Stone brings a sense of monumentality in miniature. Pre-washed, it’s safe for all livestock and aquatic plants. Its dramatic form adds height, character, and timeless geological elegance to both aquatic and terrestrial nature creations. Key Points Color: Layered grey stone with subtle beige and white mineral veins Nano Scale: Sized ≈ 3–10 cm, ideal for tanks under 40 L / 10 gal. Mountain Character
