Care

The cellophane sword grows submerged or emersed across much of the Americas, and small land forms also occur. Its submerged leaves are thin and translucent, 10–45 cm long, which gives it the name; emersed leaf blades are 5–12 cm on stalks up to 55 cm. Wikipedia keeps it in Echinodorus (it is the type of the genus) while most other swords have moved to Aquarius. It is easy to grow but soon outgrows an average aquarium, so use it in the background of a large tank with a deep, rich substrate and good light. It prefers soft, slightly acidic water and does poorly in hard water. Temperature and pH figures are our estimate, not from the sources.

Breeding

By division, by plantlets that form on the flower stem, or from seed.

Compatibility and tank mates

Sword leaves are fairly tough, but large cichlids, goldfish and other diggers may uproot young plants or chew soft new leaves; root them well. Good with tetras, angelfish, discus and other tropical community fish. Snails may graze old leaves.
