Enhance the beauty of your aquarium with this individually cast action aerating aquarium ornament. The poly/resin casting features fish safe colors and glazing that prevent fading and provide vivid colors that create a very realistic Large Clam Shell that opens to reveal a crab inside. The Action Large Clam Shell is safe for all aquariums - freshwater and saltwater.
Requires the use of a small air pump, airline tubing and an airline valve for precision control (all sold separately from Aquatic Edge).
