Scientific Name

The scientific name of this popular plant is Microsorum pteropus.

Lighting Requirements

Java Fern thrives under low to moderate lighting. Providing 6 to 10 hours of light per day will support its growth and maintain its vibrant green coloration. It can tolerate lower light conditions, making it suitable for various aquarium setups.

Care Level

With a care level of 2 on a scale of 1 to 10, Java Fern is very easy to care for. Its hardy nature makes it ideal for both beginners and experienced aquarists.

Preferred Water Parameters

• Temperature: 68°F to 82°F (20°C to 28°C)
• pH Level: 6.0 to 7.5
• GH Level (General Hardness): 3 to 10 dGH
• KH Level (Carbonate Hardness): 2 to 8 dKH

Placement

Java Fern is best placed in the midground or background of your aquarium. Its rhizome-based growth allows it to be attached to rocks, driftwood, or other hard surfaces, making it an excellent choice for creating a natural, well-integrated look. Avoid planting the rhizome directly in the substrate, as it should remain above the soil.

Growth Rate

Java Fern has a slow to moderate growth rate. It develops dense clusters of leaves that add texture and depth to your aquascape. Regular trimming can help manage its shape and prevent overcrowding.

CO2 and Fertilizer

Supplemental CO2 is not necessary for Java Fern, but it can promote healthier growth and enhance coloration. Regular liquid fertilization, particularly with iron and trace elements, will support its overall health and vitality.

Potential Problems

Java Fern is generally resilient but may experience issues such as algae growth or slow growth if water quality, lighting, or nutrients are not optimal. Ensure stable conditions and provide adequate maintenance to keep it thriving.

Tropical or Cold Water?

Java Fern thrives in tropical water conditions, with a stable temperature range between 68°F to 82°F (20°C to 28°C) being ideal for its growth.

What Fish Can Eat It?

Most fish do not typically consume Java Fern. However, certain herbivorous or larger species might occasionally nibble on its leaves. In a well-maintained community tank, it generally remains safe from being eaten.

A Fun Fact
