In this complete guide, we’re going to dive deep into everything you need to know. We’ll cover how to plant them (hint: you don’t!), how to care for them, and how to turn your aquarium into the effortless masterpiece you’ve always wanted. Let’s get growing!
Why This Duo is Every Aquarist’s Dream Team
So, what makes this combination so special? It’s simple: they share almost identical care requirements but offer wonderfully different aesthetics. This synergy makes them the perfect starting point for any aquascape and a reliable foundation for even the most advanced tanks.
The Unbeatable Benefits of Java Fern and Anubias
If you’re looking for reasons to add these plants to your tank, the list is long. Here are just a few of the incredible benefits of java fern and anubias that make them a staple in the hobby:
- Extremely Hardy: These plants are tough as nails. They can tolerate a wide range of water parameters, lighting conditions, and even a bit of beginner neglect. They’re the definition of “set it and forget it” aquarium plants.
- No Substrate Needed: Unlike most plants, they feed from the water column through their roots and a specialized stem called a rhizome. This means you can attach them to rocks, driftwood, or decor, opening up endless aquascaping possibilities.
- Low Light Tolerant: You don’t need a fancy, expensive light fixture. Both plants do perfectly well, and often better, in low to moderate lighting, which also helps keep nuisance algae at bay.
- Great for Fish: Their broad leaves provide excellent shelter and a sense of security for shy fish and fry. They also create surfaces for beneficial bacteria to grow, contributing to a healthier ecosystem.
- Slow Growing: Forget constant trimming. Their slow growth rate means your aquascape will look great for longer with minimal maintenance.
Similar Care, Different Textures
The magic of this pairing lies in their visual contrast. Java Fern (Microsorum pteropus) has long, flowing, bright green leaves that create a sense of movement and a wild, jungle-like feel. It’s perfect for adding height and filling in the background or midground of your tank.
Anubias (especially popular varieties like Anubias barteri var. nana) offers a completely different look. It has thick, waxy, deep green leaves that grow in a low, bushy pattern. Its robust structure provides a strong anchor point in your aquascape, perfect for the foreground or attached to a central piece of driftwood.
Together, they create a beautiful, multi-layered aquascape with zero extra effort, as they both follow the same simple care rules.

The Golden Rule: Don’t Bury the Rhizome!
If you remember only one thing from this article, let it be this. The single biggest mistake beginners make is planting these like a typical stem plant, burying their base in the gravel or sand.
Both plants have a thick, horizontal stem-like part called a rhizome. This is where the leaves and roots grow from. If you bury the rhizome, it will be cut off from light and flow, causing it to rot and kill the entire plant. Always keep the rhizome above the substrate.
How to “Plant” Java Fern and Anubias the Right Way
So, if you can’t bury them, what do you do? You attach them to hardscape! This is the most crucial part of learning how to java fern and anubias successfully. You have two excellent, easy options:
- The Super Glue Method (Our Favorite): This is the quickest and cleanest method. Just make sure you use a cyanoacrylate-based super glue, like Gorilla Glue Gel or any other brand of gel super glue. It’s completely aquarium-safe and cures instantly underwater.
- Pat the plant’s rhizome and the spot on your rock or wood dry with a paper towel.
- Apply a few small dabs of gel super glue to the rhizome.
- Press the plant firmly onto the hardscape for about 30 seconds.
- You can place it directly back into the aquarium! The glue will cure and hold fast.
- The Fishing Line or Thread Method: A more traditional approach. This is great if you want a non-permanent solution or prefer not to use glue.
- Choose a dark-colored cotton thread or clear fishing line.
- Position your plant on the rock or driftwood.
- Carefully wrap the thread or line around the rhizome and the hardscape several times until it feels secure.
- Tie it off with a secure knot and snip the excess. Over time, the plant’s roots will grip the surface, and the cotton thread will dissolve. You may need to cut away fishing line later if you wish.
Lighting, Water, and Fertilizers
The beauty of these plants is their simplicity. You don’t need to stress over perfect parameters.
- Lighting: Low to moderate light is ideal. If you have a powerful light, place the plants in a shaded area of the tank. Too much direct light can cause their leaves to be covered in stubborn spot algae.
- Water Parameters: They aren’t picky. They will do well in a pH range of 6.0-7.5 and can tolerate both soft and hard water. Standard tropical temperatures (72-82°F or 22-28°C) are perfect.
- Fertilizers: Because they feed from the water, they appreciate a good all-in-one liquid fertilizer. A weekly dose after your water change is more than enough to provide the nutrients they need to stay green and healthy. CO2 is absolutely not necessary.
Propagation: How to Get More Plants for Free!
One of the most rewarding parts of keeping these plants is how easy they are to propagate. You’ll never have to buy them again!
Propagating Anubias
This is incredibly straightforward. Once your Anubias rhizome is long enough (at least 2-3 inches), you can simply take it out of the tank and make a clean cut with a sharp pair of scissors or a razor blade. Ensure each new piece has at least 3-4 healthy leaves. That’s it! You now have two plants. Just attach the new piece to some hardscape, and it will continue to grow.
Propagating Java Fern
Java Fern gives you two easy options for propagation:
- Rhizome Division: Just like Anubias, you can cut the rhizome into smaller sections, making sure each piece has several leaves.
- Adventitious Plantlets: This is the cool part! Healthy Java Ferns will often grow tiny new plantlets directly on their older leaves. You might see little roots and leaves forming. Once these plantlets are about an inch tall, you can gently pull them off the parent leaf and attach them to a new spot in the tank. It’s a self-propagating machine!
Solving Common Problems with Java Fern and Anubias
While these plants are nearly indestructible, you might encounter a few minor issues. Don’t worry—here are some java fern and anubias tips for troubleshooting the most common problems with java fern and anubias.
Problem: My Java Fern Leaves are Developing Dark Brown or Black Spots and Melting.
The Cause: This is often called “Java Fern Melt.” It can be caused by a sudden change in water parameters when you first introduce the plant. Sometimes, the dark spots are actually spores, which is how the fern reproduces. It’s not necessarily a sign of poor health!
The Solution: Be patient. As long as the rhizome is firm and healthy, the plant will recover. Trim away any heavily melted or decaying leaves to keep the tank clean. New, stronger leaves adapted to your water will soon grow from the rhizome.
Problem: My Anubias Leaves are Covered in Green Spot Algae.
The Cause: This is almost always a sign of too much light. Because Anubias leaves are tough and long-lasting, algae has plenty of time to establish itself, especially under bright lighting.
The Solution: Reduce your lighting period to 6-8 hours per day or move the plant to a more shaded area of the tank. You can also introduce algae-eaters like Nerite snails or Amano shrimp, which love to graze on these surfaces.
Problem: The Leaves on Both Plants are Turning Yellow and Transparent.
The Cause: This is typically a sign of a nutrient deficiency, most commonly potassium or nitrogen.
The Solution: Start dosing a comprehensive liquid fertilizer if you aren’t already. A weekly dose will usually resolve this issue and restore the leaves to a vibrant green. Ensure you’re doing regular water changes to replenish trace elements.
Sustainable and Eco-Friendly Java Fern and Anubias Practices
As responsible aquarists, we can make choices that are better for the environment. When it comes to these plants, embracing sustainable java fern and anubias practices is easy and rewarding.
A great eco-friendly java fern and anubias approach is to seek out tank-raised or locally grown plants. This reduces the demand for wild-collected specimens, which can damage natural habitats. Better yet, connect with a local aquarium club or find hobbyists online. People who own these plants almost always have extra cuttings to sell or trade for cheap. Sharing your propagated plants is a fantastic way to participate in the community and keep the hobby sustainable.
Frequently Asked Questions About Java Fern and Anubias
Do Java Fern and Anubias need CO2?
Absolutely not! This is one of their biggest selling points. They thrive in low-tech tanks without any supplemental CO2, making them perfect for beginners.
Can I plant Java Fern and Anubias in sand or gravel?
No, you should never bury the rhizome (the thick, stem-like part) in the substrate. This will cause it to rot. You can, however, tuck just the thin, stringy roots into the substrate for stability, as long as the rhizome remains fully exposed above it.
What fish are safe to keep with these plants?
Almost all of them! The leaves of both plants are very tough and waxy, so even plant-eating fish like many cichlids and goldfish tend to leave them alone. They are an excellent choice for virtually any community tank.
How fast do Java Fern and Anubias grow?
Very slowly. You might only see one new leaf every few weeks. This is a huge benefit for maintenance, as your aquascape will keep its shape for a long time without needing constant pruning.
