Best Dragon Stone for Aquascaping (2026)
As an Amazon Associate I earn from qualifying purchases.
Dragon stone, also called Ohko stone, is a clay-based rock prized for its deeply pitted, cratered texture that adds instant drama to a hardscape. Its warm, earthy tones and jagged crevices make it a favorite for nature-style and mountain-themed layouts, and moss or tiny plants tuck neatly into its holes. Because it is relatively light and porous, it is easy to stack into ledges and peaks. Look for pieces with varied shapes and interesting faces, and give new stone a good rinse to clear out loose clay dust before scaping. This hardscape suits aquascapers who want bold, textured structure and a rugged, aged appearance in their tank. It works especially well in iwagumi and diorama scapes where the rock is the star. Dragon stone is generally considered inert enough for most setups, though very soft-water keepers may want to monitor parameters. If you love intricate detail and natural weathered character, dragon stone delivers striking results.
