    Description

    Eleocharis acicularis, commonly known as dwarf hairgrass, is one of the most popular foreground carpeting plants in the aquarium hobby. Its fine, needle-like leaves grow in dense tufts that spread via runners to gradually form a natural, grass-like carpet across the aquarium floor.

    It is a practical choice for low-tech aquariums, growing under medium light without CO2 supplementation. Carpeting is slower without CO2 but still achievable with a nutrient-rich substrate and patience. Adding CO2 injection significantly accelerates both growth and lateral spread for those wanting a faster result.

    Supplied as an established potted plant, Eleocharis acicularis suits aquariums from 30 litres upward. It is best planted in small tufts spaced a few centimetres apart across the foreground, allowing the runners to connect and fill in the gaps over time into a seamless grassy carpet.

    How do you plant dwarf hairgrass in an aquarium?

    To plant dwarf hairgrass, divide it into small portions and plant them into the substrate with space between each clump. This helps it spread evenly.

    How long does dwarf hairgrass take to carpet?

    Dwarf hairgrass can take a few weeks to several months to form a full carpet, depending on lighting, CO2, and nutrient levels.

    Why is my dwarf hairgrass not spreading?

    Slow growth may be due to low light, lack of nutrients, or no CO2. Improving these conditions will help the plant spread and form a carpet faster.
