Why Plant Java Fern in an Aquarium?

Java fern is a popular choice for aquarium planting among aquarists because it is a very low maintenance plant. It is one of the most adaptable plants to aquarium life and is known for its hardiness and resilience. Java fern can help keep the aquarium clean and clear by absorbing nitrates and other pollutants from the water. It can also create shelter for fish and other aquatic inhabitants and can help oxygenate the water, creating a more natural and healthy environment for your fish.

Requirements for Planting Java Fern

Java fern is not a difficult plant to keep in an aquarium, but there are some requirements that need to be met in order for it to thrive. First, the water needs to be between 6.5 and 7.5 pH, and the temperature should be between 75 and 82 degrees Fahrenheit. Java fern also prefers soft, slightly acidic water and needs a moderate amount of lighting. Lastly, the tank should have enough space for the plant to spread out and grow, as it can reach between 10 and 20 inches in height.

Tips for Planting Java Fern in an Aquarium

When planting Java fern, it is best to purchase it in a pot or container. This way, you can make sure that your aquarium is well suited to the needs of the plant before introducing it into the tank. Before planting, make sure to rinse the plant off to remove any dirt or debris that may be on it. Java fern can be planted directly into the substrate, but it is better to attach it to a rock or driftwood for support. To do this, tie the plant to the rock or driftwood using fishing line or thread, and make sure that the roots are well-anchored. Java fern does not require any additional fertilizers or nutrients, so there is no need to add anything to the water.

Taking Care of Java Fern After Planting

Once the Java fern is planted, it is important to keep an eye on it and make sure that it is growing properly. If the leaves start to turn brown or yellow, this could be a sign of too much light or too many nutrients in the water. If the leaves are not growing, this could be a sign of too little light or too few nutrients. Make sure to check the water parameters and adjust them accordingly. Java fern is a slow-growing plant, so it may take a few weeks to see any new growth. It is also a good idea to prune the plant regularly to help promote new growth.


Java fern is a great plant for any aquarium, as it is easy to care for and will help create a healthy and natural environment for your fish. When planting Java fern, make sure to purchase it in a pot and rinse off the roots before attaching it to a rock or driftwood for support. Once planted, keep an eye on the plant and make sure to adjust the water parameters if needed. Lastly, regular pruning will help promote new growth and keep the plant healthy. With proper care, Java fern can be a beautiful addition to any aquarium.
