Fissidens Moss

Position and planting

Attach to wood or stone where appropriate, and keep rhizomes exposed rather than burying them.

Slow-growing moss with fine fronds; stable conditions and clean water help prevent algae from overtaking it.

Lighting, CO₂ and nutrition

Light: Medium. CO₂: Recommended. Difficulty: Hard.

The library lists added CO₂ as recommended. Stronger lighting and CO₂ require careful, balanced fertilization. Allow extra time for the plant to settle and avoid repeated large changes.

Keeping it healthy

Provide consistent light, suitable nutrition, and routine maintenance. Remove decaying leaves. Watch for algae or melting after transitions, and troubleshoot conditions before making sudden changes.
