Live Aquarium Plant Seeds/Bulbs Live Plants are essential for a well-balanced aquarium. Aponogeton bulbs are one of the easiest aquarium plants to grow. They thrive in almost all water conditions. Just drop the bulbs into the aquarium and watch them grow (6" to 8" in just 15 days.) As the roots develop, the plants anchor themselves or can be planted in the gravel for faster growth. The lush green leaves provide a rich, natural background in any aquarium. Approx. 5 bulbs per package.
