Glossostigma

Glossostigma elatinoides

The original nature-aquarium carpet: paired spoon leaves racing across the substrate wherever light pours down.

01

Overview

Glossostigma was Amano's first great lawn, and its spade-shaped leaf pairs still define the fast, hungry carpet. It grows flat only under strong overhead light; the moment shade touches it, stems tilt upward and the illusion of turf breaks.

Typical colorBright green

02

Aquascaping use

Run it as an open, sunlit lawn to the front glass with nothing overhanging it. Its slightly larger leaf reads warmer and softer than HC at typical viewing distance.

03

Planting

Plant plugs of two or three nodes at close intervals in fine, fertile substrate; runners close the gaps within weeks. It also dry-starts exceptionally well.

Substrate note

Fine active substrate

04

Light & CO₂

High, unshadowed light and steady CO₂ keep it prostrate; that geometry is non-negotiable. Cooler-than-tropical temperatures suit its origins.

Light requirementHighIntensity categories are comparative, not precise PAR targets.
Supplemental CO₂RequiredAll aquatic plants use CO₂; this describes whether injection is needed.

05

Substrate & fertilization

Feed root and column both; its speed runs on real nutrition. Starved carpets pale and slow before thinning.

Feeding behavior: Mixed feeder. Nutrient demand: high.

06

Growth, trimming & propagation

Mow to a low, even height and remove clippings; layered old growth yellows beneath new. Replant plugs from healthy trimmings to repair wear.

Propagation method

Runner separation

07

Common problems

  • !Grows vertical the instant it is shaded
  • !Layered carpets rot from underneath
  • !Demands high energy for its entire life
