The Underwater Treasures Fallen Log is perfect for aquarists looking to create an exceptionally realistic natural environment, right in the comfort of their own home. This log is not unlike what you would find sunk at the bottom of a lake or river, with well worn and textured bark to provide a more stimulating visual effect. The log itself is hollow to provide small fish like loaches, tetras and shrimp with a quiet place to rest and relax. The piece is weighted so it will not float or be dislodged by a current or flow. These incredibly realistic decorations feature unique textures and are hand crafted and painted using only the highest quality materials. Underwater Treasures ornaments are all non-toxic, and safe for use in both freshwater and saltwater aquariums. 4.75" x 2.5" x 1.75"
