In this guide, we’ll walk through everything you need to know. We’ll cover what makes this plant so special, the single most important rule for planting it (don’t worry, it’s easy!), its ideal water parameters, and how to solve the few common problems you might encounter. Let’s dive in and turn your aquarium into the thriving green oasis you’ve always wanted.
What Makes Anubias Nana the Perfect Aquarium Plant?
Before we get into the “how-to,” let’s talk about the “why.” Why do seasoned aquascapers and total beginners alike sing the praises of Anubias barteri var. nana? It’s not just hype; this plant has earned its reputation as an aquarium superstar for several key reasons.
Understanding the benefits of anubias nana aquarium plant care is the first step to appreciating just how valuable this little green gem is for your underwater ecosystem. It’s more than just a decoration; it’s a living, breathing part of a balanced tank.
A Truly Beginner-Friendly Choice
If you’re new to the world of live plants, Anubias nana is your best friend. It’s incredibly hardy and can tolerate a wide range of water conditions, temperatures, and lighting levels. Did you forget to dose fertilizer this week? Anubias nana will forgive you. Is your lighting a bit on the low side? It actually prefers that!
Its slow growth rate is another huge plus for beginners. Unlike fast-growing stem plants that require constant trimming and replanting, Anubias nana is low-maintenance. It will grow at a leisurely pace, adding a few new leaves every month, meaning you can set it and pretty much forget it.
A Versatile Aquascaping Tool
Anubias nana isn’t just tough; it’s also stunningly versatile. Its deep green, waxy leaves provide a beautiful contrast to finer-leafed plants, and its compact size makes it perfect for foregrounds and midgrounds in aquascapes of all sizes.
Because it doesn’t root in the substrate, you can attach it to almost anything—driftwood, rocks, and other decorations. This allows you to add greenery to parts of your tank where you couldn’t normally plant, creating a more natural and three-dimensional look. It’s a foundational piece in many award-winning aquascapes for this very reason.
The Golden Rule: How to Plant Anubias Nana Correctly
Alright, listen up, because this is the most important piece of advice in this entire anubias nana aquarium plant care guide. If you get this one thing right, you are 90% of the way to success. The biggest mistake beginners make is treating Anubias like a typical stem plant.
Anubias is an epiphyte. That’s a fancy word meaning it grows attached to other surfaces, not buried in the ground. It has a thick, horizontal stem called a rhizome, which is where the leaves and roots sprout from. This rhizome is its lifeline, and it must never be buried under your substrate.
Attaching to Hardscape (Driftwood & Rocks)
The best way to plant Anubias nana is to attach it to a piece of driftwood or a rock. This mimics its natural environment and ensures the rhizome gets the light and water flow it needs. Here are two easy, foolproof methods:
- The Super Glue Method (My Favorite): This is the quickest and cleanest way. You’ll need a tube of cyanoacrylate super glue—make sure it’s the gel type, as it’s easier to control.
- Pat the spot on your driftwood or rock dry with a paper towel.
- Pat the roots/bottom of the Anubias rhizome dry as well.
- Apply a few small dabs of super glue gel to the rock or wood.
- Press the rhizome firmly onto the glue spots and hold for about 30-60 seconds.
- That’s it! You can place it directly back into the aquarium. The glue is 100% fish-safe once cured (which happens almost instantly in water).
- The Thread Method: This is the classic method. You’ll need some dark-colored cotton thread or fishing line.
- Simply place your Anubias nana where you want it on the hardscape.
- Wrap the thread or fishing line around the rhizome and the object several times to secure it firmly.
- Tie a secure knot and snip off the excess. Over a few months, the plant’s roots will naturally grip the surface, and the cotton thread will dissolve away.
The “Don’t Bury the Rhizome!” Warning
So what happens if you bury the rhizome in your sand or gravel? It will rot. The rhizome needs to be exposed to the water column to breathe and absorb nutrients. When it’s smothered under substrate, it quickly suffocates, turns to mush, and the entire plant dies.
If you absolutely must place it on the substrate, you can gently wedge it between rocks or weigh it down with a plant weight, ensuring the entire rhizome is sitting on top of the substrate, not in it. The thin, wiry roots can go down into the substrate, but the thick, green rhizome must stay above ground.
The Ultimate Anubias Nana Aquarium Plant Care Guide
Now that your Anubias is properly planted, let’s talk about the day-to-day environment it needs to thrive. The good news is, its demands are minimal. Following these anubias nana aquarium plant care best practices will ensure your plant stays healthy and green for years to come.
Lighting Requirements: Less is More
This is where Anubias nana really shines—in low light! It evolved under the dense canopy of African rainforests, so it’s adapted to shady conditions. In the aquarium, it does best under low to medium lighting.
In fact, one of the most common problems people have is giving it too much light. Bright, intense lighting doesn’t make it grow faster; it just makes it a magnet for algae. Its slow-growing leaves can’t outcompete algae, so they quickly get covered in green spot algae or black beard algae under intense light. Stick to a lower light setting and a photoperiod of 6-8 hours a day for a happy, algae-free plant.
Water Parameters: Stable and Steady Wins the Race
Anubias nana is not a fussy plant when it comes to water chemistry. It will adapt to a wide range of conditions, which is why it’s suitable for almost any tank, from a simple Betta setup to a community tank.
- Temperature: 72-82°F (22-28°C) is the ideal range.
- pH: It’s comfortable in a pH range of 6.0 to 7.5.
- Hardness: It can thrive in both soft and hard water.
The most important thing isn’t hitting a specific number, but maintaining stability. Like most aquatic life, Anubias prefers a consistent environment over one with wild swings in temperature or pH.
Fertilization: A Light Feeder’s Diet
Because it’s a slow grower and pulls most of its nutrients directly from the water column through its leaves and roots, Anubias nana is a very light feeder. It does not require a nutrient-rich substrate or root tabs.
In a well-stocked community tank, the waste produced by your fish will often provide enough nitrogen and phosphates. However, it can benefit from a comprehensive liquid fertilizer dosed once or twice a week. Look for one that contains potassium and micronutrients, as these are often what’s lacking in an aquarium environment.
CO2 Injection: Necessary or Optional?
This one’s easy: completely optional. Anubias nana does not require supplemental CO2 to grow well. It is perfectly happy in a “low-tech” tank without any CO2 injection. While adding CO2 might slightly increase its growth rate, it’s absolutely not a requirement for its health and is often overkill.
Solving Common Problems with Anubias Nana Aquarium Plant Care
Even the hardiest plant can run into trouble. Fortunately, the common problems with anubias nana aquarium plant care are few and usually easy to fix. If you see something amiss, don’t panic! Here’s a quick troubleshooting guide.
Help! My Anubias has Algae on its Leaves!
This is by far the most common issue. Because the leaves are tough and long-lasting, they are prime real estate for algae, especially Green Spot Algae. The cause is almost always too much light.
- The Fix: Reduce the intensity of your light or shorten the duration it’s on each day (aim for 6-8 hours). You can also move the plant to a shadier spot in the tank, perhaps under a larger piece of driftwood or taller plants. Manually, you can gently rub the algae off the leaves with your finger or a soft toothbrush during a water change. Algae-eating critters like Nerite snails are also fantastic helpers!
Why are the Leaves Turning Yellow?
Yellowing leaves (a condition called chlorosis) usually point to a nutrient deficiency. While Anubias is a light feeder, it can sometimes lack specific micronutrients, especially in a very clean tank with a low bioload.
- The Fix: The most common culprit is a lack of potassium or iron. Start by dosing a comprehensive liquid fertilizer that contains these elements. If a new leaf comes in green and healthy, you’ve found your solution. Don’t worry about the old yellow leaves; they likely won’t recover, but you can trim them off at the base of the stem once new growth appears.
The Dreaded Rhizome Rot
If you notice the rhizome becoming soft, brown, and mushy, you’re dealing with rhizome rot. As we discussed, this is almost always caused by the rhizome being buried in the substrate and suffocating.
- The Fix: Act fast! Take the plant out of the tank. With a sharp, clean blade, cut away any soft or mushy parts of the rhizome. If you have any healthy sections left with leaves and roots, you can save them. Let the cut end “scab over” in the air for about 30 minutes, then re-attach the healthy portion to a rock or piece of wood, making sure the rhizome is fully exposed.
Propagating Anubias Nana: Creating New Plants for Free!
One of the most rewarding aspects of keeping Anubias is how easy it is to propagate. This is the heart of sustainable anubias nana aquarium plant care. Instead of buying new plants, you can simply create your own! When your plant’s rhizome has grown long and has at least 6-8 healthy leaves, you’re ready to propagate.
- Take the plant out of the aquarium.
- Identify a good spot to cut on the rhizome. You want to ensure each new piece will have at least 3-4 healthy leaves and some roots.
- Using a sharp pair of scissors or a razor blade, make a clean cut through the rhizome.
- That’s it! You now have two separate Anubias plants. You can attach the new piece to another rock or piece of driftwood and watch it grow.
This is a fantastic and eco-friendly anubias nana aquarium plant care practice that allows you to fill out your aquascape or share with fellow hobbyists without any extra cost.
Frequently Asked Questions About Anubias Nana Care
Can Anubias nana grow floating?
While it won’t die immediately if left floating, it won’t thrive. The plant’s roots naturally want to anchor to a surface. It’s much better to attach it to something so it can establish itself properly.
What fish are safe with Anubias nana?
Almost all of them! Anubias leaves are famously tough and leathery, which makes them unappetizing to most herbivorous fish. Even notorious plant-eaters like some cichlids and goldfish will usually leave Anubias nana alone, making it a fantastic choice for tanks with boisterous fish.
How fast does Anubias nana grow?
Very slowly. In a low-tech setup, you can expect to see one or two new leaves per month. This slow growth is a feature, not a bug! It means far less maintenance for you and a plant that won’t outgrow its spot in your aquascape for a very long time.
Do I need to trim Anubias nana leaves?
Generally, no. The only time you need to trim is if a leaf becomes old, yellow, or covered in stubborn algae. If you do need to trim a leaf, use sharp scissors to snip the leaf’s stem (the petiole) as close to the main rhizome as possible without damaging the rhizome itself.
Your Journey to a Greener Tank Starts Now
There you have it—everything you need to master anubias nana aquarium plant care. It truly is one of the most rewarding and forgiving plants in the hobby. It asks for very little but gives back so much, providing shelter for your fish, adding natural beauty, and helping to create a stable, healthy ecosystem.
Remember the golden rules: keep that rhizome out of the substrate, don’t blast it with too much light, and enjoy its slow, steady growth. By following this guide, you’re not just planting an Anubias; you’re setting yourself up for success and building confidence in your ability to keep a beautiful planted tank.
So go ahead, grab a piece of driftwood, a tube of super glue, and your new favorite plant. You’ve got this. Go forth and grow!
