Java Fern (Microsorum petropus) is an easy-to-acquire aquatic plant.
Java Fern is one of the world’s most widely used plants in planted aquariums. It slow growth, unique leaf structure, and reproduction method makes it an aquarium smash hit.

The current can also allow it to attach itself to something that its roots can hold on to. You can also choose where it will go by burying the roots in some gravel or tying it onto a piece of wood, rock, or other decor. Super glue gel is my favorite method to plant Java Fern. Make a simple glue bead from the decor piece you wish to attach the fern to. It should be held against the glue for at least 30 seconds. Then let it dry in the air for 3 minutes. Watch it grow in the tank! You must make sure that the rhizome, the twig-like portion of the plant, is not buried. All the roots and leaves extend out of this rhizome. If it is buried under gravel or sand it will rot. This plant has a great advantage: it doesn’t need substrate. Java Fern is a great choice for tanks with bare bottoms.

It can be kept in a bucket for up to a week and still live! One example: A bulb in one of my breeding tanks was burned out over several months. Yet, every time I put a light in the tank to catch the fry the Java Fern looked amazing!

Java Fern can be dangerous so it is best to not over prune or start a tank. It is a slow-growing plant that can be difficult to control. A good crew of algae eaters and sucker fish go a long way to ensuring it wins the battle. It can be planted with other faster-growing plants such as Vallisneria.
If you do lose the battle to algae, just pull off a couple of leaves and float them in a dish of water under some light. You can then remove the plantlets and put them back in the tank. This will hopefully win the battle. So what are you waiting for? Enjoy Java Fern!
