Keep this plant trimmed to prevent unsightly, straggly stems. It does not tolerate chemicals or pollution well but otherwise is not fussy about water conditions.
[edit] Breeding/Propagation
Seed and cuttings.
[edit] Notes
Without adequate light, this plant will become spindly with weak stems, not attractive at all. Because of its low temperature requirements, it is ideal for use with fishes like White Cloud Mountain Minnows (Tanichthys albonubes) and other coolwater fishes. Though it would seem to be a natural with Goldfish, no such luck, as they find the soft leaves delectable. Keep the water movement gentle. It will develop nodal roots to extract nutrients from the water. It is also quite happy to grow as a floating plant on the surface of the water close to the light where it just might produce small white flowers.
