Java Fern Needle
Rhisome with 10 leaves
**Needle Leaf Java Fern (Microsorum pteropus 'Needle Leaf')** is a popular aquatic plant commonly used in aquariums. This plant is a variant of the standard Java Fern, known for its narrow, needle-like leaves, making it an attractive addition to aquascapes. Here's a detailed look at this plant:
### **Characteristics:**
- **Scientific Name:** Microsorum pteropus 'Needle Leaf'
- **Common Name:** Needle Leaf Java Fern
- **Family:** Polypodiaceae
- **Origin:** Native to Southeast Asia, including regions like Thailand, Malaysia, and Indonesia.
- **Leaf Appearance:** The leaves are long, thin, and needle-like, typically dark green. They can grow up to 20-30 cm (8-12 inches) in length.
- **Growth Habit:** Slow-growing and typically spreads through rhizomes. It does not need to be planted in substrate; instead, it attaches itself to rocks, driftwood, or other surfaces.
- **Light Requirements:** Low to moderate light is preferred. High light can cause algae growth on the leaves.
- **Water Parameters:**
- pH: 6.0 - 7.5
- Temperature: 68-82°F (20-28°C)
- Hardness: Soft to moderately hard water
- **CO2 Requirements:** Does not require additional CO2, though it can benefit from it.
### **Care Tips:**
- **Planting:** Avoid burying the rhizome in the substrate, as this can cause the plant to rot. Attach it to driftwood or rocks using fishing line or thread until it secures itself.
- **Maintenance:** It requires minimal maintenance. Remove any dead or decaying leaves to prevent algae buildup.
- **Fertilization:** Benefits from liquid fertilizers, but excessive nutrients are not necessary.
- **Propagation:** Propagates through rhizome division; you can trim the rhizome and reattach pieces elsewhere in the tank.
### **Benefits in Aquariums:**
- **Fish Compatibility:** Safe for most fish, including herbivorous species. Fish typically avoid eating Java Fern due to its tough leaves.
- **Provides Cover:** Great for aquascapes as it provides hiding spots for small fish and fry.
- **Low Maintenance:** Ideal for beginners due to its hardy nature and minimal care requirements.
Needle Leaf Java Fern is highly valued for its aesthetic appeal and ease of care, making it a perfect choice for both novice and experienced aquarists.
