Species description

Care, breeding and tankmates

Plant profile

Placement

Midground

Can be used as a floating plant or loosely planted in the background. It forms dense tangles that are excellent for breeding setups. Due to its sprawling nature, it's not ideal for highly structured layouts.

Botanical form

Stem

Features very thin, branching stems with numerous small, pointed leaves. The plant creates a complex, tangled mass that is light green in color. Its structure is highly brittle and snaps easily.

Growth

Fast

Extremely fast-growing, especially when floating near the light source. It can quickly cover the water surface, requiring frequent removal to prevent shading.

Substrate

None

Column fertilization

Recommended

Feeds almost exclusively from the water column, whether rooted or floating. A basic all-in-one liquid fertilizer is more than enough to keep it healthy.

Root fertilization

None

Does not require root fertilization. Its roots are primarily used for anchoring rather than nutrient uptake, and it thrives completely free-floating.

Trimming

Regular

Trimming simply involves pulling out handfuls of the excess mass. Care must be taken as the stems break easily, leaving small fragments that will grow into new plants.

Propagation

Cuttings

Propagates naturally through fragmentation; any broken piece of stem will quickly grow into a new plant. It spreads aggressively if left unchecked.

Sensitivity

Moderate

Sensitive to some liquid carbon supplements and strong chemical treatments. It prefers stable parameters but is generally quite hardy.

Layout role

Midground, Background

Primarily used in breeding tanks or shrimp setups as a functional plant rather than for aesthetics. It provides unparalleled hiding spots for fry and natural grazing areas for invertebrates.
