01

Overview

Under suitable conditions its side branches create a triangular, fir-like pattern. The plant is forgiving, though its best form depends on clean flow and regular thinning.

Aquascaping use

Use restrained patches to imply age on driftwood or to soften stone transitions. Avoid coating every surface, which can flatten the composition.

03

Planting

Spread a very thin layer and secure with thread or small dots of aquarium-safe gel adhesive. Thick initial clumps often detach underneath.

Substrate note

Attach in a thin layer to hardscape

04

Light & CO₂

It grows without injected CO₂, but cleaner branching and faster recovery are common in stable CO₂ systems.

Light requirementMediumIntensity categories are comparative, not precise PAR targets.
Supplemental CO₂BeneficialAll aquatic plants use CO₂; this describes whether injection is needed.

05

Substrate & fertilization

Regular, modest water-column nutrition is sufficient. Gentle flow helps carry nutrients through dense mats.

Feeding behavior: Water-column feeder. Nutrient demand: low.

06

Growth, trimming & propagation

Lift loose cuttings while trimming and thin to the attachment point periodically. Reattach healthy tips when the base becomes shaded.

Propagation method

Moss fragmentation

07

Common problems

  • !Dense mats collect debris
  • !Loose fragments spread into other plants
  • !Warm stagnant water produces sparse growth
