WIO Nano Rocks - Black Ryuoh

Black Ryuoh Nano Stone is the miniature version of one of the most iconic aquascaping stones-prized for its powerful aesthetics and dramatic mineral veining. With deep graphite-black tones and bright white lines, each stone is a sculptural piece that enhances depth, tension, and definition in aquascapes under 40 L. Its rugged texture and raw edges evoke ancient mountain ridges or shadowy ravines, making it ideal for strong Iwagumi compositions, layered cliffscapes, or as bold accents alongside wood and plants. Sized between 3 and 10 cm, these nano stones offer precision and presence in any small-scale design. Each piece is 100% natural, pre-washed, and safe for all aquatic and terrestrial life. Whether you're working on a nano aquarium, terrarium, or paludarium, Black Ryuoh Nano Stone delivers sculptural strength in miniature form.
