When supplied as a potted plant and/or bunch, it is very important that it is not planted in direct company of invertebrates. The plant should be watered for at least a week - with regular water changes - before introducing it into your aquarium. The plant nurseries commonly use raw material from Asia for these variants. When planted into an existing ecosystem, it is possible that invertebrates could be harmed. There should be no issues with a new set-up - but regular water changes are advised as well.

Description

The Giant Vallisneria is an easy plant that grows fast, suitable for large aquariums. Mostly labeled Vallisneria gigantea and V. sp. "Gigantea" in the trade, the plant actually belongs to the Australian species Vallisneria australis.

In most aquariums the leaves grow so long that they float on the surface (50-150 cm, width 2 cm and above). In these cases the plant needs pruning to stop it taking too much light from plants growing beneath.

The leaves are tough and strong, so they are normally not eaten by herbivorous fish.

The Giant Vallisneria is easy to propagate using runners, which are prolific if the bottom is nutritious. It grows also at cooler temperatures in unheated tanks.

Vallisneria australis can be planted in sand, but then requires good fertilisation.
