Ohko Stone, also commonly known as Dragon Stone, is an extremely popular hardscape choice in the aquarium hobby that is characterized by its notorious golden yellow dragon-like scale textures. The overall shape of the rock features numerous nooks and small craters that are great for anchoring aquatic plants and moss species while also providing a safe haven for sensitive or skittish fish and shrimp. Composed of a clay-like substance, Ohko Stone is extremely lightweight and fragile when compared to other rock options. It can be easily broken down into smaller pieces to suit a wide range of aquarium tanks and is inert so the water chemistry will not change when adding this stone into a planted tank.  

Alternatively, they can be used to tie aquatic moss species or attach plants such as Anubias and Bucephalandra, adding a sense of maturity to a newly planted aquascape layout. Accent stones are without limit and can be used to aquascape large aquarium tanks and nano aquarium tanks.
