SubstrateSource 'Cholla Wood' aquarium driftwood is all-natural, dried husk of the Cholla cactus. Its porous structure and soft texture make it both a unique aquarium decoration and a functional feature. Use it as a base to attach Anubias, Java Fern, and aquatic mosses, or as a site for small fish and shrimp to find food and shelter. SubstrateSource Cholla Wood can also be used as natural decor and climbing surface in your hermit crab habitat! This 2-pack includes two of our hand selected pieces. Each piece is approximately 6-inches long and 0.75-1.5 inches in diameter.
