Description
Water lettuce forms floating rosettes of velvety leaves resembling a small lettuce, with a feathery hanging root system that can reach twenty centimetres. That root mesh is its greatest virtue in the aquarium: it filters nitrate with enormous efficiency and offers shelter to fry. Be aware that in many countries it is an invasive species and its sale is restricted.

Taxonomy verified.
The aquarium care values (light, substrate, CO2 and water ranges) have no citable source: GBIF supports the taxonomy and distribution, not the cultivation. A source for plants is still to be agreed.
