Vallisneria sp. Gigantea from Asia is an easy plant that grows fast, suitable for large aquariums. In most aquariums the leaves grow so long to float on the surface (50-150 cm, 2 cm wide). So the plant needs pruning to avoid taking too much light from the plants growing below. The leaves are hard and strong, so they are not normally eaten by herbivorous fish.
The American Vallisneria spreads easily through runners, which are prolific if the bottom is nutritious
