Java Moss (Vesicularia dubyana) care guide
Java Moss (Vesicularia dubyana) (Vesicularia dubyana) — low light, 18-28 °C, pH 5.5-8, no CO2.
Overview
Java Moss (Vesicularia dubyana) (Vesicularia dubyana) is an aquatic plant of the family Hypnaceae, listed in the Aquairi knowledge base as a beginner-level species. It is typically grown under low light and without obligatory CO2 injection on any substrate. Historical name often applied to large-leaved java moss; in modern taxonomy related closely to Taxiphyllum barbieri. Grows easily in a wide range of temperatures and provides shelter for shrimp.
Taxonomy
- Family: Hypnaceae
- Genus: Vesicularia
- Scientific name: Vesicularia dubyana
- Common synonyms: Singapore Java Moss
Habitat
Vesicularia is a genus of aquatic mosses (Hypnaceae) of humid tropical Asia, growing on rocks, wood and stream banks; the branching shoots attach by rhizoids rather than true roots. In the Aquairi knowledge base, populations associated with this form are recorded from Asia.
Growth requirements
- Lighting: low
- CO2: not required
- Temperature: 18-28 °C (64-82 °F)
- pH: 5.5-8
- GH: 2-16 °dGH
- Substrate: any
- Maximum height: 8 cm
- Growth rate: medium
- Recommended placement: epiphyte on wood or rock
Placement
Attached to wood or rock with thread or gel; it carpets hardscape and is undemanding, tolerating low light without added CO2. In the Aquairi knowledge base this form is recommended for the midground as an epiphyte on hardscape under low light and without obligatory CO2 injection, using any substrate.
Propagation
Multiplied by simple division: detached portions are tied or weighted onto new surfaces, where they re-attach and continue to branch. Documented propagation techniques for this entry include: stem cuttings.
Common issues
Detritus and algae lodge in dense old growth; periodic trimming and gentle flow keep the moss clean and compact.
