This hardy fern adapts easily to many aquarium setups.
Distinctive dark-green foliage
The unique leaf structure adds depth and subtle detail to aquascapes.
Forms elegant hardscape colonies
Over time the fern spreads naturally across wood and stone.
Creates contrast in layered aquascapes
The darker leaves balance brighter green stem plants.
Origin: Southeast Asia (cultivated variety)
Type: Rhizome plant
Growth Rate: Slow to Moderate
Size: Height: 15–25 cm (6–10 in) Width: 15–20 cm (6–8 in)
Natural Habitat: Java ferns naturally grow along shaded tropical streams where they anchor themselves to submerged wood, rocks, and tree roots in areas with steady water flow.
Special Considerations: Attach the rhizome to hardscape such as driftwood or rocks rather than burying it in substrate. Moderate water movement helps keep the leaves clean and free of debris.
Did You Know?
Many Java fern varieties were developed through selective cultivation in aquatic plant nurseries. Growers observed natural mutations in leaf shape and growth patterns, then propagated those plants to create distinctive cultivars such as ‘Black Forest’ with darker foliage and unique leaf structures.
Tank Size: 20 L (5 gallons) or larger recommended.
Plant Placement: Often attached to driftwood or rock structures in the midground, where its dark leaves create a forest-like effect in aquascapes. It pairs nicely with tall background plants such as Rotala nanjenshan or Hygrophila polysperma, while mosses like Taiwan moss or Spiky moss can enhance the natural look of the hardscape.
Compatibility: Compatible with a wide range of aquarium species including tetras, rasboras, dwarf gouramis, Corydoras, shrimp, and snails. The firm leaves provide resting surfaces for fish and grazing areas for shrimp such as Amano shrimp and crystal shrimp. The dark foliage also contrasts beautifully with silver fish like rummynose tetras.
Substrate: Rhizome should remain above substrate and attached to wood or stone.
Light: Low to medium lighting (20–40 PAR) for 6–8 hours daily.
Temperature: 22–28 °C (72–82 °F)
pH: 6.0 – 7.5
Hardness: Soft to moderately hard water (3–12 dGH)
CO₂: Optional.
Care & Propagation: Propagate by dividing the rhizome or separating plantlets that develop on mature leaves. Minimal trimming is required due to its slow growth.
Portion Size 1 carefully selected rhizome plant attached to natural lava rock, ready for aquarium placement.
Plant Size Plants are typically 5–7 cm (2–3 in) tall depending on the species and growth stage.
Plant Type Rhizome plant securely attached to lava rock for easy placement in the aquarium.
Snail-Free & Aquarium Safe Plants are grown without chemicals that could harm fish, shrimp, or other aquarium inhabitants and are carefully inspected to ensure they are snail-free.
Transition After Shipping Some older leaves may change appearance as the plant adapts to new aquarium conditions. Healthy new leaves will grow from the rhizome.
Planting Guide
- 1.Remove the protective plastic packaging.
- 2.Rinse the plant and lava rock gently with clean water.
- 3.Place the lava rock directly on the aquarium substrate or position it within your aquascape.
- 4.Ensure the rhizome remains above the substrate and is not buried.
If preferred, you may carefully remove the fishing line and attach the plant to driftwood, rocks, or aquarium decorations.
