Dwarf Hairgrass Mini

Eleocharis pusilla

plantfreshwater

Eleocharis pusilla (Dwarf Hairgrass Mini) is a nano-scale hairgrass species producing extremely fine, short blades reaching only 3–5 cm, making it noticeably shorter and denser than standard Dwarf Hairgrass (E. parvula). Under CO2 injection and good light it spreads rapidly via runners to form a tight, lawn-like foreground carpet highly prized in Nature Aquarium-style layouts. It is particularly effective in nano aquariums where even E. parvula would be too tall.

Eleocharis Belem

Eleocharis sp. 'Belem'

plantfreshwater

An extremely fine, thread-like hairgrass originating from the Belem region of Brazil, producing the thinnest, most delicate stems of any Eleocharis in the hobby. Blades rarely exceed 3–5 cm tall, creating a wispy, ultra-fine carpet that looks unlike any other aquatic grass. Demands good light, CO₂, and a nutrient-rich substrate to spread reliably. A favourite among competitive aquascapers who want a finer-textured foreground than standard dwarf hairgrass provides.

Fissidens Fontanus

Fissidens fontanus

plantfreshwater

A flat, feather-like aquatic moss with a unique branching structure that differentiates it from round-leaved mosses like Java Moss. It attaches readily to rock and wood and grows as a distinctive carpet of interlocking fronds. Slower growing than Java Moss, it produces a tidier, more formal appearance and is popular in Nature Aquarium and Iwagumi layouts.

Flame Moss

Taxiphyllum sp. 'Flame'

plantfreshwater

Flame Moss gets its name from the way its upright, twisted stems spiral and curve upward — resembling flickering orange flames when viewed in flowing water. Unlike most mosses that grow laterally, Flame Moss grows vertically, making it uniquely suited for mid-height mounding effects on rocks and wood. It is slow growing but compact, rarely requiring trimming, and stays tidy in low-flow areas.

Giant Bacopa

Bacopa amplexicaulis

plantfreshwater

A larger Bacopa species with distinctive clasping (amplexicaul) leaves that wrap around the stem at the base. The blue-violet flowers it produces above the waterline are among the most attractive of any aquarium plant. Submerged leaves are broad and light green, giving it a lush, robust appearance. Grows quickly and is very adaptable — excellent as an emersed pond margin plant or fully submerged background plant.

Giant Hairgrass

Eleocharis montevidensis

plantfreshwater

The tallest commonly kept Eleocharis species, producing stiff, dark green needle-like blades up to 30–50 cm (12–19.5 in) tall. Creates a dramatic, grass-like background that mimics riparian meadows. Unlike dwarf hairgrasses, it does not form a dense carpet but instead grows as individual clumps. Very undemanding and one of the few Eleocharis that thrives without CO₂ injection. Excellent for paludarium setups or tall tanks where vertical structure is desired.

Glossostigma

Glossostigma elatinoides

plantfreshwater

Glossostigma elatinoides was one of the first foreground carpeting plants popularised by Takashi Amano in the Nature Aquarium style. Its tiny spoon-shaped leaves form an extremely low, dense green carpet when grown under high light with CO2. Without strong light it grows upward rather than creeping, defeating the purpose. It is one of the most demanding carpeting plants but produces one of the most pristine, turf-like results when conditions are ideal.
