Hygrophila polysperma, commonly known as dwarf hygrophila, dwarf hygro, Miramar weed or Indian waterweed, is an aquatic plant in the acanthus family.
Light intensity seems to be rather unimportant, though lower light values will result in proportionately slower and more diminutive growth. Fertilization, as well, seems to be of limited significance in the maintenance of this species.
CO2 supplementation is definitely not a necessity for this species, and it can be grown in non-CO2 aquaria without problems.
