Give your fish the steady stream of fresh bubbles they need with the Penn-Plax Aqua-Mist Air Stone Bar in green. This compact 4-inch aerator drops right into your tank and gets to work, lifting a curtain of bubbles that helps keep the water moving and well oxygenated. It is a small piece of gear that makes a real difference for the little swimmers who depend on you. Think of it as an easy upgrade to the home you have already built for them.

• Produces lots of bubbles, so your tank gets a livelier, more active look that draws the eye.
• Delivers a better oxygen supply for your fish, helping them breathe easier in their everyday environment.
• Finished in green, so it reads as a natural accent rather than an obvious piece of equipment.
• Compact 4-inch length suits smaller tanks or pairs neatly inside a larger aquascape.
• Can be buried under the gravel, giving your aquarium a cleaner, tidier look up top.
• Tucking it below the substrate hides the hardware while the bubbles still rise through your scene.
• Sized as a single unit, so you know exactly what arrives and can plan your layout around it.
• Simple to position wherever you want that gentle rise of bubbles to begin.
• An easygoing way to add both movement and aeration to a fresh setup or an established display.
• Comes from Penn-Plax, a name that also makes tanks, ornaments, air pumps, tubing, filters, and more for the fish hobby.

Whether you are aerating a new tank or refreshing a setup that has been running a while, this green air stone bar keeps the bubbles coming and the look clean. Pair it with your air pump and tubing, settle it into the gravel, and let your fish enjoy the lift. It is the kind of quiet, dependable detail that helps a thriving tank feel complete, and your fish will be living in water that simply works better for them.
