Vallisneria spiralis: a backdrop for medium aquariums

Vallisneria spiralis forms long, narrow green ribbons that rise to the surface and bend along it, creating a constantly moving backdrop. It is smaller and more manageable than gigantea, which makes it suitable for medium tanks. It tolerates hard water better than most plants, though it has one clear enemy: it cannot cope with excess copper salts or some algae treatments.
