Live plants are among the most beautiful and natural aquarium decorations available.
They also are natural filters, adding some oxygen and removing fish waste from the aquarium. Aquatic plants do not all have the same requirements for survival. Certain lighting, temperature, hardness and pH conditions will allow some plants to survive and thrive while others perish. If you are unwilling to match your aquarium conditions to those required by a demanding species, stick to the varieties that will do well under your conditions. Plant them carefully.
