Mini Dwarf Hairgrass (Parvulus)
Mini Dwarf Hairgrass (Parvulus)
Mini Dwarf Hairgrass, botanically Eleocharis parvulus, is a shorter and finer-bladed form of dwarf hairgrass producing delicately thin, hair-like leaves that create a particularly refined, miniature grass carpet ideally scaled for nano tanks and detailed foreground work. The finer blade compared to acicularis creates a more delicate, airy carpet texture with a lighter, more translucent quality that suits small-scale compositions.
Care tip: Mini Dwarf Hairgrass (Parvulus) grows best in moderate to high lighting with CO₂ recommended. Maintain temperatures of 68–82°F and pH 6.0–7.5. Regular fertilization supports healthy growth.
Growing to just 2 to 4 inches, parvulus stays consistently compact even under moderate lighting — a practical quality for aquarists who want a low, neat grass foreground without constant trimming demands. Like all hairgrass species it spreads via runners, gradually covering the foreground substrate. CO₂ supplementation and good lighting produce the fastest, densest carpet development.
This moderate plant grows in moderate to high lighting with CO₂ recommended. The wide temperature range of 68 to 82°F reflects broad thermal tolerance. A pH of 6.0 to 7.5 provides comfortable conditions. Regular fertilization supports vigorous runner production and the consistently fine blade quality that defines the parvulus form.
In the aquascape, Mini Dwarf Hairgrass creates a finer, more delicate grass carpet that suits nano tanks and small-format compositions where full-sized hairgrass would appear coarse or disproportionate. The lighter, finer texture provides a softer, more luminous foreground quality than acicularis. In Iwagumi-style nano layouts it creates a proportionately scaled grass-meadow of genuine beauty.
Mini Dwarf Hairgrass is the nano tank aquascaper's grass carpet of choice — finer, more delicate, and more proportionate to small-scale compositions than standard hairgrass. Its refined texture and practical compact height make it one of the most useful foreground plants for small and nano planted aquariums.
