Java fern (Microsorum pteropus) is a beautiful and popular aquatic plant that is often used in aquariums. It is a hardy plant that is relatively easy to care for, making it a good choice for both beginners and experienced aquarists. Java fern can be planted in a variety of ways, but the most common method is to attach it to driftwood or rocks using thread or fishing line.
One of the best things about Java fern is that it is very adaptable. It can tolerate a wide range of water conditions, including different pH levels and hardness levels. It also does not require a lot of light, making it a good choice for low-light aquariums. However, Java fern does not do well in water that is too warm or too cold. The ideal temperature range for Java fern is between 72 and 82 degrees Fahrenheit (22 to 28 degrees Celsius).
Java fern is a slow-growing plant, but it can form dense clumps over time. It is a good choice for creating natural-looking aquascapes. Java fern can also be used to provide shelter for fish and invertebrates. The leaves of Java fern are long and narrow, and they can provide a hiding place for small fish and shrimp. Java fern is also a good choice for planted tanks because it helps to remove nitrates from the water.
Choosing the Right Environment
Java ferns are versatile plants that will thrive in a wide range of aquatic environments. However, there are a few key factors to consider when choosing the best place to plant them:
- Lighting: Java ferns prefer low to medium lighting. They will tolerate higher light levels, but the leaves may become smaller and less vibrant.
- Water flow: Java ferns prefer slow to moderate water flow. They can tolerate faster water flow, but the leaves may become torn or damaged.
- Substrate: Java ferns can be planted in a variety of substrates, including sand, gravel, or soil. They prefer a substrate that is rich in nutrients and organic matter.
- Water chemistry: Java ferns prefer water with a pH of 6.0 to 8.0 and a hardness of 5 to 15 dGH.
Java ferns can also be attached to driftwood or rocks using thin thread or fishing line. This is a good option for creating a more natural look in your aquarium.
| Lighting | Water flow | Substrate | Water chemistry |
|---|---|---|---|
| Low to medium | Slow to moderate | Rich in nutrients and organic matter | pH 6.0 to 8.0, hardness 5 to 15 dGH |
Preparing the Substrate
The substrate you choose for your Java Fern will largely determine its health and growth. Here are the key factors to consider when preparing the substrate:
Materials
There are several options for the substrate used for Java fern.
| Substrate Type | Pros | Cons |
|---|---|---|
| Driftwood | Provides a natural-looking environment, supports epiphytic growth. | Can be difficult to find the right size and shape, may not be suitable for all types of Java fern. |
| Rocks | Easy to find and use, provides stability. | Can be difficult to attach Java fern securely, may not provide sufficient nutrients. |
| Substrate | Provides a nutrient-rich environment, makes it easier to attach Java fern. | May alter water parameters, can be messy. |
Size and Shape
The size and shape of the substrate should be appropriate for the size of the Java Fern you are planting. For smaller ferns, a small piece of driftwood or rock will suffice. Larger ferns may require a larger piece of driftwood or a substrate tray.
Attachment
The substrate should provide a way to securely attach the Java Fern. Driftwood and rocks can be used with super glue or thread. Substrate can be used with plant weights or root tabs.
Attaching the Java Fern
Java ferns are epiphytic plants, meaning they grow attached to other objects rather than in soil. When planting Java fern, you will need to choose a suitable object to attach them to.
Options for Attaching Java Ferns:
| Object | Method |
|---|---|
| Driftwood | Use cotton thread or fishing line to tie the rhizome of the fern to the driftwood. |
| Rocks | Use super glue or aquarium-safe epoxy to attach the rhizome to the rock. |
| Mesh baskets | Line the basket with Java moss and place the ferns inside. Secure the lid with a rubber band or wire. |
| Java moss mat | Wrap the rhizome of the Java fern with a small piece of Java moss mat and secure it with cotton thread. |
| Other plants | Attach the rhizome to the leaves or stems of other plants in the tank using cotton thread or fishing line. |
No matter which method you choose, be sure to position the rhizome of the Java fern horizontally. This will allow for new growth to spread freely.
Tips for Attaching Java Fern:
- Use a soft material, such as cotton thread or fishing line, to tie the Java fern to the object.
- Do not tie the fern too tightly, as this can damage the rhizome.
- If using super glue or epoxy, apply it sparingly to avoid harming the plant.
- Allow the attachment point to dry completely before placing the Java fern into the water.
- Add iron supplements to the water column or substrate.
- Lower the pH level using acidic buffers or CO2 injection.
- Provide a nutrient-rich substrate that is rich in iron.
Planting in Aquarium Soil
Planting Java fern in aquarium soil is a simple and effective way to create a lush and healthy underwater environment. Here are the steps involved:
1. Choose the Right Soil
Select an aquarium soil that is specifically designed for aquatic plants. This type of soil will provide the necessary nutrients and support for the Java fern to thrive.
2. Prepare the Soil
Rinse the aquarium soil thoroughly before use to remove any dust or debris. This will help ensure that the soil is free of contaminants.
3. Plant the Rhizome
Java fern should be planted by its rhizome, which is the horizontal stem that runs along the base of the plant. Dig a small hole in the soil and carefully place the rhizome inside, ensuring that it is not buried too deeply.
4. Secure the Plant
After planting, use weights or plant anchors to secure the Java fern in place. This will prevent the plant from being uprooted by water currents or other disturbances. Here’s a detailed table summarizing the ways to secure the plant:
| Method | How to Secure |
|---|---|
| Weights | Place small, inert weights (e.g., pebbles, aquarium gravel) around the base of the plant to hold it down. |
| Plant Anchors | Use specialized plant anchors, which are small, plastic or metal devices designed to grip the rhizome and embed in the soil. |
| String or Fishing Line | Tie a thin string or fishing line around the rhizome and gently secure it to a stable object in the aquarium, such as a rock or piece of driftwood. |
Using Driftwood or Rocks
Java ferns can be attached to driftwood or rocks using a variety of methods, including:
Tying
One of the simplest methods is to use thread or fishing line to tie the fern’s rhizome (the horizontal stem that runs along the bottom of the plant) to the driftwood or rock. Make sure to tie the fern loosely enough so that it can still grow and spread.
Gluing
Another option is to use super glue or aquarium-safe epoxy to attach the fern’s rhizome to the driftwood or rock. This method is more permanent than tying, but it is important to use a product that is safe for both the plant and the fish in your tank.
Planting
If you are using a substrate that is suitable for rooted plants, such as gravel or sand, you can plant the Java fern directly into the substrate. Simply dig a small hole in the substrate and place the fern’s roots in the hole. Pack the substrate around the roots and gently firm it down.
Weighting Down
If you do not want to tie, glue, or plant the Java fern, you can simply weigh it down with a small rock or piece of driftwood. This method is less secure than the other methods, but it is still an option if you do not want to damage the plant.
| Method | Advantages | Disadvantages |
|---|---|---|
| Tying | Easy to do, inexpensive | Can damage the plant if tied too tightly |
| Gluing | Permanent, secure | Can be difficult to do, can damage the plant if not done carefully |
| Planting | Naturalistic look, provides nutrients | Requires a suitable substrate |
| Weighting Down | Easy to do, inexpensive | Less secure than other methods |
Lighting
Java ferns prefer low to medium lighting conditions. Intense light can cause the leaves to turn brown and crispy. If you are keeping Java ferns in a tank with high-intensity lighting, you can provide them with some shade by planting them under taller plants or using floating plants to reduce the amount of light that reaches them.
Fertilization
Java ferns do not require a lot of fertilizer, but they will benefit from occasional fertilization. You can fertilize Java ferns with a liquid fertilizer that is high in potassium and nitrogen. You can also use root tabs to provide them with a slow-release source of nutrients.
Substrate
Java ferns can be planted in any type of substrate, but they prefer a substrate that is rich in nutrients. You can use a potting mix that is specifically designed for aquatic plants, or you can use a mixture of sand and gravel.
pH and Hardness
Java ferns prefer a pH between 6.0 and 7.5 and a hardness of between 5 and 15 dGH. If your water is outside of this range, you may need to adjust it using a pH buffer or a water softener.
CO2 Injection
Java ferns do not require CO2 injection, but they will benefit from it. CO2 injection will help them to grow faster and produce more leaves.
Temperature
Java ferns prefer a temperature between 72 and 78 degrees Fahrenheit. If your water temperature is outside of this range, you may need to adjust it using a heater or a chiller.
Monitoring Water Parameters
To ensure the optimal growth and health of Java Fern, it is essential to monitor the water parameters regularly and make adjustments as necessary.
pH
Java Ferns prefer a slightly acidic to neutral pH between 5.5 and 7.5. Using a pH test kit, monitor and adjust the pH level by adding specific chemicals designed for aquarium water, either pH up or pH down.
Temperature
Java Ferns thrive in a temperature range of 72-82°F (22-28°C). Utilize a thermometer to measure the tank temperature and adjust it using a heater for colder tanks or a fan or chiller for warmer tanks.
KH (Carbonate Hardness)
KH measures the amount of carbonate and bicarbonate ions in the water. Java Ferns prefer a KH of 3-8 dKH. Use a KH test kit to check the KH and add a carbonate buffer to increase it or perform water changes with softer water to lower it.
GH (General Hardness)
GH indicates the total amount of dissolved minerals in the water. Java Ferns prefer a GH of 5-15 dGH. Employ a GH test kit to monitor GH and adjust it by adding mineral supplements or performing water changes with harder or softer water.
Nitrates
Nitrates are a byproduct of fish waste and can accumulate in the water. Java Ferns tolerate nitrate levels of up to 20 ppm but can be negatively impacted by higher concentrations. Use a nitrate test kit to monitor nitrate levels and perform water changes to reduce them if necessary.
Phosphorus
Phosphorus is an essential nutrient for plant growth, but excess phosphorus can promote algae growth. Java Ferns prefer phosphate levels below 1 ppm. Utilizing a phosphate test kit, monitor phosphate levels and limit the use of phosphorus-rich fertilizers or perform water changes to reduce them.
Table of Recommended Water Parameters for Java Fern
| Parameter | Recommended Range |
|---|---|
| pH | 5.5 – 7.5 |
| Temperature | 72 – 82°F (22 – 28°C) |
| KH (Carbonate Hardness) | 3 – 8 dKH |
| GH (General Hardness) | 5 – 15 dGH |

Planting Java Fern
To plant Java Fern, choose a location with medium to bright indirect light. The plant prefers slightly acidic water with a pH of 5.5 to 7.0 and a temperature range of 72-82°F (22-28°C). Secure the rhizome, the horizontal root-like stem, to a rock or driftwood using thread or fishing line. Do not bury the rhizome in the substrate.
Trimming and Propagation
Trimming
Java Ferns grow quickly and may need to be trimmed occasionally. Use clean, sharp scissors to remove old or damaged leaves. Cut the leaves at the base, where they attach to the rhizome. Avoid cutting the rhizome itself, as this can damage the plant.
Propagation
Java Ferns can be propagated by dividing the rhizome. Carefully remove the plant from the tank and use a sharp knife to cut the rhizome into several pieces. Each piece should have at least one leaf. Replant the pieces as described above.
Java Ferns can also be propagated by growing new plants from plantlets. Plantlets are small shoots that develop on the underside of mature leaves. When the plantlets are large enough, they can be carefully removed from the leaf and planted in the substrate.
| Propagation Method | Instructions |
|---|---|
| Dividing the rhizome | Cut the rhizome into several pieces, each with at least one leaf. Replant the pieces. |
| Growing from plantlets | Remove plantlets from mature leaves and plant them in the substrate. |
