Overview

An aquarium plant must never reach the wild: throwing away cuttings or emptying a tank into a stream can be enough to establish it.

Growing in the aquarium

It grows floating or rooted in the substrate, where it can become especially bulky. Medium light is already enough to grow it; more light, nutrients and CO₂ speed up its development. Plan a large tank for a single plant. The plantlets formed on the leaves let you renew the plants.
