Eleocharis pusilla: Mini Dwarf Hairgrass
Eleocharis pusilla, commonly known as Mini Dwarf Hairgrass, is one of the shortest and finest varieties of hairgrass tissue cultures available to the aquarium hobby. It is often incorrectly or interchangeably sold under the name Eleocharis parvula or Eleocharis acicularis ‘Mini’, but E. pusilla is the species widely cultivated and known for its exceptionally compact growth, reaching a height of only 1 to 2 inches (3-5 cm).
This plant is the go-to choice for aquascapers aiming to create a realistic, manicured “lawn” or “meadow” effect, particularly in Nano Aquariums or Iwagumi-style layouts where scale is critical. It spreads horizontally and forms dense, fine-textured mats that add depth and natural aesthetics to the tank.

FAQ
What is the difference between Eleocharis pusilla and Eleocharis parvula?
Eleocharis pusilla is a distinct species known for its compact growth and fine texture. While sometimes sold under the name Eleocharis parvula, E. pusilla is more commonly cultivated and recognized for its ideal size and appearance in small aquariums.

Is this plant suitable for a nano aquarium?
Yes, this plant is specifically recommended for nano aquariums due to its small size and ability to create a natural, manicured meadow effect without overcrowding.
Irene Murray –
I used this hairgrass in my 10-gallon nano tank and it grew beautifully within a few weeks. The plants stay very short and form a dense, natural-looking lawn. Perfect for Iwagumi style. Easy to maintain and doesn’t require much light.
Warren Lee –
The plant arrived healthy and spread well in my tank. I was worried about it being too tall, but it stayed under 2 inches. Great for creating a meadow effect in a small setup. Only needed occasional trimming.

This is exactly what I needed for my aquascape project. The fine texture and compact size make it ideal for a realistic grassy look. It’s been growing steadily and looks natural after just two months.
