Fissidens fontanus

Fissidens fontanus | Phoenix Moss — Named for its fountain-like fronds that unfurl in layered, feathered sprays, giving the appearance of an aquatic plume.
How to grow:
Thrives fully submerged in aquariums or paludariums with gentle water flow. Anchor to rocks or driftwood; avoid burying rhizoids. Trim to maintain shape and prevent shading.

Growing requirements:

• Water: Soft, clean, slightly acidic to neutral; prefers rain, RO, or dechlorinated water

• Soil / substrate: Not required; attaches to hardscape

• Humidity: Fully aquatic or ≥90% in emersed culture

• Sunlight: Low to medium light (2,000–5,000 lux); 8–12W aquarium light

• Temperature: 18–26 °C

Growth habit:
Rosette-like fronds arranged in a flat, double-sided pattern; rhizoids attach to surfaces; non-vascular

Growing season & conditions:
Year-round in stable aquatic environments

Acclimatization on transport:
Highly sensitive to drying; keep submerged or in sealed, water-filled bags

Fun fact:
In India, Fissidens species are sometimes found in shaded, spring-fed hill streams, where they act as microhabitats for aquatic insect larvae.
