Echinodorus amazonicus is a very common aquarium plant. The plant is beautiful and easy to care. They bear long, ovoid leaves with a pointed tip that grow on short stems. Their leaves are dark or bright green in color. These plants propagate through side shoots off of their leaves. Plants need nutrient-rich substrate to tolerate most lighting conditions, but moderate to high light levels are ideal. Injections of CO2 are not necessary, but will help the plant grow faster if desired. Amazon sword plants will grow submersed or emersed.
