Product Review
Java Fern is one of the most popular and beginner-friendly aquarium plants, known for its hardy nature, low maintenance, and elegant green leaves. This plant thrives in low to medium light conditions and does not require CO₂ injection, making it ideal for low-tech tanks. Unlike rooted plants, Java Fern should be attached to driftwood or rocks, as burying the rhizome can cause rot. Its slow growth and resistance to algae make it a great choice for any aquarium setup.
