Dwarf Hairgrass (Eleocharis parvula) is a very popular foreground or mid-ground plant for the freshwater aquarium. This hardy, fast-growing plant can quickly “carpet” most aquariums. It is shorter than most other hairgrass species.
This variety of Hairgrass requires moderate to high lighting. It does not have to be pruned often unless more horizontal growth is desired. If used for carpeting the aquarium, it should be trimmed weekly to promote horizontal growth. It will grow very quickly in nutrient-rich substrate. It will also benefit from CO2 supplementation, but this is not required.
Like most plants, Hairgrass will benefit from supplementation such as Seachem Flourish, Flourish Excel, nitrogen, and other plant supplements.
