Nano Rocks

If you’re looking for a beautiful stone that won’t affect your water chemistry, consider the Ohko Aquascaping Dragonstone. These inert nano rocks have a unique, scale-like texture with delicate details and crevices that result in an aged look with hints of yellow, red, and orange against a brown background. Because they have a clay-like composition, Ohko rocks are slightly more brittle than other aquascaping stones, so you can break them into smaller pieces with just a chisel and a hammer — perfect for tanks of all sizes.

Our Selection

Our aquascaping dragonstone originates from Japan near ponds and lakes, and its highly textured surface makes it a popular choice among hobbyists and professional aquascapers. At Modern Aquarium, we currently sell our nano rocks in two-pound bags that contain a variety of sizes, shades, and shapes.

Tank Decor Safety

All of our nano rocks are safe for fish, shrimp, and other aquarium inhabitants. While our aquarium decor is cleaned prior to storage, we suggest that you clean your rocks of dust and other debris under tap water again before placing them in the tank.
