The Underwater Treasures Royal Palace is an enchanting castle designed fishkeepers who want to add a bit of royal flair into the aquarium design. The castle itself sports deep blue shingles and gold tipped spires, catching the eye and providing an exceptional visual effect that both fish and fishkeeper will come to adore. The hollow castle provides space for smaller creatures to rest, relax and hide. 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" x 4" x 5.75"
