Action Air® Treasure Chest & Diver Live-Action Aerating Aquarium ...
Treasure Chest measures approximately 2-1/2″x 2″x 2-1/2″ high when open. This Action Air® Treasure Chest Diver gives your aquarium that sunken treasure look feel. Diver floats and is approximately 3-1/2″ tall. 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. 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.
