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 gives your aquascape an aged look that can't 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 easily be broken down with chisel and hammer.
Dragon Stone is inert and will not influence your water chemistry, making it the ideal layout material for any aquarium.
