Dragon Stone (Ohko)
Dragon Stone, also known as Ohko Stone, is a popular aquascaping rock named after it's scale-like texture. The natural details and crevices give your aquascape an aged look that cannot be duplicated with artificial decorations. The clay-like composition of this type of stone makes it brittle compared to other rocks, allowing larger rocks to be broken down with a chisel and hammer easily.
Dragon Stone is inert and will not influence your water chemistry, making it the ideal layout material for any aquarium.
