4. Fish and Shrimp Friendly
Windelov Java Fern is non-toxic to fish and invertebrates, which makes it an excellent choice for community tanks. Additionally, its broad leaves provide shelter and hiding places for shy fish and shrimp, making them feel secure. It also provides a source of biofilm, which shrimp and small fish enjoy grazing on.
Water Conditions for Windelov Java Fern
Windelov Java Fern is highly adaptable to a range of water parameters. However, ensuring the right water conditions will help it thrive and grow healthily.
1. Temperature
Windelov Java Fern prefers warm water temperatures between 72°F to 82°F (22°C to 28°C). This temperature range mimics the tropical conditions of Southeast Asia, where it originates. It can tolerate slight fluctuations in temperature, but keeping the water within this range will promote healthy growth.
2. pH Level
The ideal pH for Windelov Java Fern is 6.0 to 7.5, though it can tolerate water that is slightly more acidic or alkaline. Maintaining the pH within this range will allow the plant to grow optimally.
3. Water Hardness
Windelov Java Fern thrives in soft to moderately hard water. The preferred dGH (general hardness) is between 3 and 8 dGH, although it can tolerate slightly harder water. Avoid water that is too soft or too hard, as it can affect the plant’s growth and nutrient absorption.
4. Water Flow
Windelov Java Fern prefers slow to moderate water flow. In the wild, it grows in slower-moving waters, so it’s best to provide gentle circulation in your aquarium. A strong current can damage the delicate fronds, so a gentle filter or aeration system is recommended to avoid stress.
Lighting Requirements for Windelov Java Fern
Windelov Java Fern is low-light tolerant, making it an ideal plant for tanks with low-tech setups or low-light conditions. However, proper lighting is essential for promoting healthy growth and preventing algae overgrowth.
1. Light Intensity
Windelov Java Fern can thrive in low to moderate light levels. In low-light aquariums, it may grow slowly but still remain healthy and vibrant. For moderate light, aim for 1.5 to 3 watts per gallon of light. High-intensity lighting may lead to algae problems, especially on the plant’s leaves.
2. Light Duration
Providing 8 to 10 hours of light per day is ideal for Windelov Java Fern. Consistent lighting duration helps the plant with photosynthesis while preventing algae overgrowth. To simulate natural day-night cycles, use a timer to regulate the light duration.
3. Light Type
Windelov Java Fern benefits from full-spectrum light, which mimics natural sunlight and provides the necessary wavelengths for photosynthesis. LED lights or fluorescent tubes designed for aquariums are great options. T5 fluorescent bulbs or LED lighting with a color temperature of around 6500K will provide the proper light spectrum for healthy growth.
Substrate and Planting Windelov Java Fern
One of the standout features of Windelov Java Fern is that it does not need to be planted in the substrate. Instead, it grows well when attached to rocks, driftwood, or other decorations in the tank. This makes it a perfect option for aquascaping and creating visually dynamic aquariums.
1. Substrate Preference
While Windelov Java Fern doesn’t need to be buried in the substrate, it will benefit from being attached to a surface that provides stability. You can attach the plant to rocks, driftwood, or decorative objects. If you want to plant it in the substrate, it can be done, but be sure not to bury the rhizome, as this can cause it to rot.
2. Attachment Method
To attach Windelov Java Fern to rocks or driftwood:
- Gently remove the plant from its pot and clean off any excess substrate.
- Use fishing line, cotton thread, or aquarium-safe glue to attach the rhizome (the thick stem) to your chosen surface.
- Ensure the rhizome is not buried in the substrate, as it can lead to rot. The roots can be buried, but the rhizome should remain exposed to the water.
Fertilization for Windelov Java Fern
Windelov Java Fern is a relatively low-maintenance plant when it comes to fertilization. However, it will benefit from the addition of nutrients to promote healthy growth, especially in aquariums with low nutrient levels.
1. Liquid Fertilizers
If you have a planted aquarium with other plants, you can supplement Windelov Java Fern with a liquid fertilizer containing both macro and micronutrients. Be careful not to over-fertilize, as excessive nutrients can lead to algae blooms.
2. Root Tabs
If the plant is attached to driftwood or rocks, and not planted in the substrate, consider using root tabs to provide nutrients directly to the roots. Root tabs are slow-release fertilizers that are placed near the plant's root system.
3. CO2 Supplementation
Windelov Java Fern is a non-CO2-dependent plant. It can thrive without additional CO2 injection, making it ideal for low-tech tanks. However, if you're running a high-tech aquarium with CO2, the plant will grow slightly faster and produce lush, vibrant fronds.
Common Issues and Troubleshooting
Although Windelov Java Fern is a hardy and low-maintenance plant, it may encounter a few problems if water conditions or care practices aren’t optimal. Below are some common issues you may face and their solutions:
1. Yellowing Leaves
If the leaves turn yellow, it is often a sign of nutrient deficiency or inadequate lighting.
- Solution: Ensure the plant is receiving adequate lighting and nutrients. Adding liquid fertilizers or root tabs can help resolve this issue.
2. Algae Growth
Algae growth on the leaves of Windelov Java Fern can occur if the lighting is too intense or there is an excess of nutrients in the water.
- Solution: Reduce the lighting intensity or duration and clean the algae off the plant’s leaves. Adding algae-eating fish or invertebrates like Amano shrimp can help control algae in your tank.
3. Rhizome Rot
If the rhizome is buried in the substrate, it may begin to rot. Rotting can lead to the death of the plant.
- Solution: Make sure the rhizome is not buried in the substrate. Only the roots should make contact with the substrate, and the rhizome should be attached to rocks or driftwood.
