    Description

    Microsorum pteropus, universally known as Java fern, is pre-attached to a small piece of natural lava rock, creating a compact and instantly ready planted feature. The broad, wavy-edged dark green leaves grow from a creeping rhizome that attaches naturally to the porous surface of volcanic rock, making lava an ideal growing medium that the plant anchors to firmly over time.

    Java fern is one of the easiest aquarium plants available. It grows in low to medium light without CO2 injection and is tolerant of a wide range of water conditions and temperatures. It is generally left alone by most fish including many cichlids, and shrimp enjoy grazing on the biofilm that forms on the broad leaf surfaces. Growth is slow but the plant is very long-lived.

    The plant is pre-established on the lava rock so no further attachment is needed — simply rinse and place in the aquarium. Never bury the rhizome. The mini size suits aquariums of 20 litres and above and works effectively in any position in the tank. The lava rock sinks immediately without weighting.

    Plant Sizes

    The image of the plant you'll be receiving is just an example of what you can expect. Each plant is unique and may vary in size and shape, so it won't be an exact match to the photo. If we provide a size guide, keep in mind that it's just an estimate and that plants can vary in size depending on the time of year.

    Product FAQs

    Helpful details before you buy.

    Does Java fern need to be planted in substrate?

    No — the rhizome is already attached to the lava rock. Just place it in the tank. Never bury the rhizome in substrate.

    Does it need CO2 or special lighting?

    No — Java fern is one of the most low-tech plants available, growing under standard aquarium lighting without CO2.

    Is lava rock safe for aquarium use?

    Yes — lava rock is aquarium-safe and inert. It does not significantly affect water chemistry and provides excellent surface area for beneficial bacteria.

    Is it suitable for shrimp tanks?

    Yes, fully. Java fern is shrimp-safe and shrimp enjoy grazing on the biofilm on the leaf surfaces.

    What tank size does the mini suit?

    It works from 20 litres upward, making it one of the most practical planted rock options for small and nano aquariums.
