This slow-growing plant comes in different variations, like Needle Leaf, Trident, and Windelov (or lace) Java Fern. Java Ferns are great plants for Betta tanks because they are incredibly easy to grow, do well in low lighting and a large range of water parameters. This species grows relatively large, so they are better suited for bigger planted aquariums. Java Fern can be attached directly onto driftwood, rocks or other aquarium decoration using line or glue. Please keep the rhizomes (where the leaves are attached to) above the substrate or the plant may start to rot. Propagation of java fern is easy and straightforward; simply cut or pull apart rhizomes to be replanted. For more aquarium plants, click here!
