Penn-Plax Tropical Clam Aquarium Ornament

The Penn-Plax Tropical Clam Aquarium Ornament not only adds a touch of décor to your tank, but it also provides valuable aeration properties. The clam shell moves as bubbles are generated for ongoing entertainment. Just connect it to a standard 3/16 airline from an air pump (sold separately), and sit back and watch. The ornament is made of a durable plastic resin that’s safe for freshwater and saltwater aquariums. This entertaining ornament is plenty of fun to watch, and you’ll be creating a healthier environment for your fishy friends, too.
