The Underwater Treasures Alien Skull is not your average aquarium ornament! This authentic alien skull is the perfect addition to the aquarium of a discerning UFO hunter, with the large eyes and hollow head ideal for small fish and invertebrates to swim around and relax. The intergalactic skull has a shiny metallic color that highlights just how exotic and extraterrestrial this rare artifact really is. 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. 3.75″ x 3.25″ x 3.75″
