Penn-Plax Silicone Sea Anemone (Blue) – A soft, flexible aquarium ornament that looks like a blue sea anemone. Made of silicone that undulates with the water’s movement, it creates lifelike motion in your tank. This ornament glows under actinic/blue lighting for a vibrant reef effect and offers a gentle place for shy fish or aquarium creatures to hover around, enhancing the visual appeal of freshwater or saltwater setups.
