Japanese Ohko Dragon Rock

Japanese Ohko dragon rocks are very similar to holy lace rocks, with a unique pitted surface and unusual texture. Originating in Japan, these are classic examples of sedimentary rock formed through the compression of organic materials and clay. Ohko rocks range in color from deep, reddish brown to yellowish hues, creating a beautiful contrast against deep green live plants. This type of rock is completely safe for your aquarium and won’t affect the pH of your water. At Modern Aquarium, we offer Ohko rocks in several styles to help you personalize your aquarium hardscape with the perfect visual accessories and safe places for fish to play and hide.
