Liven up your aquarium with the Penn Plax Sports Line of Bubbling Aquarium Decorations. The Penn Plax Action-Air Soccer Player Bubble / BobbleHead Aquarium Ornament offers a unique ornament that will draw lots of visual interest to your tank. This aquarium decoration serves two purposes by oxygenating the water and helps reduce boredom for fish (and it also looks pretty amazing!). The bubbling bobblehead is made of quality resin and is hand painted; measuring 2.4'' x 2.4'' x 5.5'' inches. The aerating fish tank ornament is freestanding so it can be placed anywhere in your fish tank. Coordinate this soccer player with the Soccerball or with any of our other sports style resins for a complete look. Easy Set Up 1) Place the ornament into your aquarium wherever you like. 2) Connect included airline tubing to adjustable air source (not included). 3) Adjust air pressure for best operation
