How To Plant Crested Java Fern

Crested Java Fern is a type of aquarium plant that is extremely popular among aquarists. It's easy to grow, provides plenty of shade, and is a great way to add some visual interest to a tank. Growing Crested Java Fern is not difficult, but there are a few things to keep in mind when planting it in your aquarium. In this article, we'll provide you with tips on how to properly plant Crested Java Fern in your tank.

Choose the Right Spot

One of the most important things to consider when planting Crested Java Fern is the location in your aquarium. It needs to be in an area that receives plenty of indirect light, as this will ensure that it gets the energy it needs to grow. Avoid areas that are overly dark or that receive direct sunlight, as these can cause the leaves to burn. Also, make sure that the chosen spot has good water circulation, as this will help the plant to stay healthy.

Prepare the Substrate

Before planting Crested Java Fern, you'll need to prepare the substrate. The best way to do this is to add a thin layer of gravel or sand to the chosen spot in your aquarium. This will help to hold the plant in place and provide it with the nutrients it needs to stay healthy. It's important to use a substrate that is free of any contaminants, as this could harm the plant.

Soak the Plant

Once you've chosen the spot and prepared the substrate, it's time to soak the plant. This process will help to remove any dirt or debris that may be stuck to the leaves. To do this, simply place your Crested Java Fern in a bowl of lukewarm water and let it soak for 10-15 minutes. Once it has been soaked, you can gently rinse it off with freshwater and then place it in the aquarium.

Secure the Plant

Once the plant is in the aquarium, you'll need to secure it in place. The best way to do this is to use a few pieces of aquarium-safe driftwood or rocks. Place these around the plant so that it is held firmly in place. This will help to ensure that it stays in the same spot and does not move during water changes or other activities.

Provide Nutrients

Crested Java Fern also needs a few nutrients to grow. You can do this by adding a small amount of liquid fertilizer to the water every few weeks. This will provide the plant with the necessary nutrients to stay healthy and keep growing. You can also add a few pieces of aquarium-safe driftwood or rocks to the tank, as these will help to provide the plant with additional nutrients.

Monitor Growth

Once you've planted your Crested Java Fern, you'll need to monitor its growth. Make sure to check on the plant every week or so to ensure that it is healthy and growing properly. If you notice any signs of disease or other issues, you should take action right away.

Trim the Plant

Crested Java Fern can grow quite large, so it's important to trim it regularly. This will help to keep the plant from becoming overgrown and blocking out light from other plants in the tank. You can use a pair of aquarium-safe scissors to trim the leaves back and keep the plant looking neat and tidy.


Planting Crested Java Fern in your aquarium can be a great way to add some visual interest and provide plenty of shade for your fish. It's important to choose the right spot in your tank, prepare the substrate, soak the plant, secure it in place, provide nutrients, and monitor its growth. With a little bit of care and attention, you can keep your Crested Java Fern healthy and thriving.
