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. Java Fern tolerates most lighting conditions and many environments – from soft acidic water to alkaline conditions, and even brackish tanks! Planting Java Fern is easy; simply throw it into your water. Really - even if you just drop it in, it'll start growing. Java Fern will thrive while floating, or the current may allow it to attach to something that its roots can hold onto. 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 décor. When it comes to growing Java Fern, almost any light will do. Indeed, it will be thankful for any brightness in its life! Java Fern isn't picky about which spectrum of lighting you're using or even the number of watts. However, Java Fern will do best if provided with a 6700k spectrum bulb. Any range from low to medium-high light is perfect for this plant. At the very high end range of light, you can actually burn or melt it. So resist the urge to recreate the Sahara Desert over your tank. Java Fern can live off such little light that many aquarists have forgotten it for several weeks in a bucket and it still lives! Assuming you've got it planted and are giving it some light, your Java Fern will soon be reproducing. Tiny Java Ferns are formed at the edge of the leaves. Once they mature they drop off and attach themselves to wherever they should land. You can also break leaves off and let them float in the aquarium. The plant even has an emergency contingency – if it starts to die it immediately produces new plantlets, sometimes as many as 20 babies per leaf. This is a great method for getting ready to setup a new tank or propagating it to give to a new fish friend.
