Hairgrass Giant (Eleocharis Montevidensis)

Hairgrass Giant, also known as Eleocharis Montevidensis, is a very popular aquarium plant. This grass-like plant produces thin, straw-like leaves that may reach up to 8 inches in length. However, the height of the leaves will vary depending on light conditions, with brighter and more intense light producing shorter plants.

Care & Maintenance for Hairgrass Giant

Hairgrass giant is easy to care for, but good light, fertilization, and substrate are recommended. The fine grass-like leaves of Hairgrass Giant may collect undesirable waste from the aquarium water. Providing good water flow, a debris-free aquarium environment, and scavenging fish such as corydoras catfish will help keep the plant clean.        

  • Minimum Lighting Required: Moderate
  • Temperature Range: 64-82°F
  • Tank Placement: Midground and Background

Hairgrass Giant can be planted in the midground and background areas of the aquarium. The plant looks best when planted densely in large groups. Under good conditions, it will begin to spread from runners, creating grass-like fields in the aquarium.

Hairgrass Giant is also available potted and we offer other varieties of grass-like plants, including Hairgrass Dwarf.

    I ordered 2 bunches and got a whole lot of hair grass! I was a able to separate out the little bunches and cover 1/4 of my 40 gallon breeder thinly. Very healthy and I'm super happy with this purchase.
