Java fern is an ideal addition to a planted aquarium, as it is low-maintenance and easy to care for. Its thick leaves and ability to absorb carbon dioxide make it a great addition to any freshwater tank. This plant also helps prevent algae growth by absorbing nitrates from the water, and it can be used as a source of filtration.
A good place to cultivate Java fern is the back of your tank, where it will cover up a lot of your tank’s surface area and look great! It also grows well on hardscapes like rocks and driftwood. To ensure that your fern doesn’t float away, tie it down firmly to an object with fishing wire or other threads. It’s a good idea to use nylon fishing wire that doesn’t leech harmful chemicals into the water.
To grow properly, Java ferns require four essential nutrients: iron, manganese, nitrogen, and phosphorous. They can also benefit from additional micronutrients such as copper, zinc, and borate. In fact, a lack of these nutrients may cause Java fern to become stunted or even die.
If you’re not sure whether or not your Java fern needs fertilizer, the best way to tell is by looking at the foliage. The leaf coloration will depend on the amount of light the plant is getting. If it has a lot of transparent or brown leaves, the lighting condition is probably too high for your plant to thrive. If the leaves are dark green and healthy, the lighting is fine.
It’s also important to note that while Java fern does not have roots, it is still a good idea to secure your plant in a stable substrate. This will help it to grow more efficiently.
The Java fern can be placed anywhere in your aquarium, but it’s best to position it at the center or on the back of your tank. This will allow it to be a focal point that helps to draw attention to your fish and plants.
In addition to being durable, Java ferns are also highly compatible with many fish and invertebrates. They can easily share your tank with a wide variety of animals, including herbivorous cichlid species, nippers, and goldfish.
When a Java fern is first added to an aquarium, it will need some time to get acclimated to the water and environment. This process is known as acclimatization and can take several weeks or months.
Once acclimated, the plant should look great and be happy to grow. It may start out looking a bit raggedy, but that will likely go away as it adjusts to the new lighting conditions and water parameters.
As the Java fern matures, it will have thick, green leaves with a leather-like texture. The leaves are also highly durable and can withstand physical damage from rowdy fish.
The leaves of the Java fern are often veined with black or brown spots, which are actually where new leaves sprout from. This is a natural part of the plant’s propagation process and occurs only on mature plants.
