Fontinalis antipyretica var. gigantea

Species description

Care, breeding and tankmates

Plant profile

Placement

Midground

It is best tied to thick driftwood branches or large stones in the midground or background. Its large size means it needs plenty of room to cascade and flow freely. It looks best when elevated, allowing the long stems to hang downwards.

Botanical form

Epiphyte

It is very similar to standard Willow Moss but features significantly larger, more robust leaves. The stems are thicker and the overall appearance is much more substantial. It forms imposing, dark green cascades that make a strong visual statement.

Growth

Medium

The growth rate is moderate, often slightly slower than the standard Willow Moss variety. It takes time to establish and form impressive, flowing clumps. Cooler water and CO2 injection will help optimize its growth rate.

Substrate

None

Column fertilization

Recommended

It benefits greatly from water column dosing of trace elements and macros. A good liquid fertilizer ensures the moss can maintain its large fronds. Feeding via the water column is essential for keeping the deep green coloration.

Root fertilization

None

As a true moss, root fertilization is completely ineffective and unnecessary. It absorbs all of its required nutrients directly from the surrounding water. The small rhizoids are only used to grip onto the hardscape.

Trimming

Occasional

Trim the longest shoots periodically to keep the clump tidy and prevent it from overgrowing neighboring plants. Trimming encourages denser, bushier growth at the base of the plant. Always remove the cut strands from the tank to prevent unwanted spreading.

Propagation

Cuttings

To propagate, simply divide the large moss cushions into smaller portions. Use fishing line or cotton thread to secure the pieces to new surfaces. They will quickly attach and begin to grow into new cascading clumps.

Sensitivity

Moderate

Like the standard species, it prefers cooler water and does poorly in high-temperature aquariums. It is prone to collecting detritus due to its large, dense structure, so good flow is required. It is also susceptible to hair algae if nutrients become imbalanced.

Layout role

Epiphyte, Midground, Background, accent

Its larger texture makes it a prominent focal epiphyte in hardscape arrangements. It is ideal for larger aquariums where its size won't overwhelm the layout. It creates a stunning, dramatic 'weeping tree' effect when placed correctly.
