Penn Plax Action Air Aquarium Ornaments bring animation and charm to your underwater world while aerating your tank. This Action Air Mini Treasure Chest is sized for those tight spots while giving your aquarium that sunken treasure look & feel. The action of the chest cover opening & closing reveals the interior treasure while bubbles escape through the open chest providing your tank with much needed air. Every Action Air ornament is created with great detail and weighted to help them stay put. Simply connect the ornament to a standard 3/16″ airline from your air pump (not included) and watch the treasure chest gently open & close as a steady stream of bubbles rise from the chest helping to aerate your tank. Use your pressure control valve (not included) to adjust the motion and the volume of air.
