Anubias Aquarium Plant Facts – The Ultimate Guide For Lush,
Have you ever bought a beautiful aquarium plant, only to watch it melt away into a sad, brown mush within a few weeks? It’s a frustrating experience that makes many aquarists feel like a lush, green aquascape is just out of reach.
I promise you, it doesn’t have to be that way. There’s a plant so tough, so forgiving, and so beautiful that it has earned a legendary reputation as the “unkillable” king of the aquarium world. That plant is Anubias.
This complete guide is packed with all the essential anubias aquarium plant facts you need to succeed. We’ll cover everything from the single most important planting rule to solving common problems and exploring stunning varieties. Get ready to transform your tank with a plant that truly works with you.
What Makes Anubias the Perfect Beginner Aquarium Plant?
So, what’s the secret behind this plant’s bulletproof reputation? It all comes down to its origins and its unique biology. Anubias species are native to the shady rivers and streams of West Africa, where they’ve adapted to a wide range of conditions.
This background makes them incredibly resilient in a home aquarium. They aren’t fussy about water parameters, they don’t demand intense lighting, and their slow growth means you won’t be constantly trimming them back. This is one of the most important benefits of anubias aquarium plant facts—it offers maximum beauty for minimum effort.
The “Unkillable” Reputation: Fact or Fiction?
While no plant is truly unkillable, Anubias comes incredibly close. Its thick, leathery leaves are unappealing to most plant-eating fish (even notorious nibblers like goldfish and some cichlids often leave it alone!).
Its real superpower, however, is its slow, deliberate growth. Unlike fast-growing stem plants that can quickly suffer from nutrient deficiencies, Anubias takes its time, making it far more forgiving if your fertilization routine isn’t perfect. There is one way to kill it, but don’t worry—we’ll cover exactly how to avoid that fatal mistake.
Slow and Steady Wins the Aquascape Race
In a world of instant gratification, the slow growth of Anubias is a feature, not a bug. It means the beautiful aquascape you create today will look almost the same months from now.
This low-maintenance nature is a huge plus for busy hobbyists. It also means the plant is less likely to experience a sudden “melting” event that can plague more delicate species when introduced to a new tank. It simply adapts and grows at its own pace.
The Golden Rule: How to Plant Anubias Correctly
If you remember only one thing from this anubias aquarium plant facts guide, let it be this: Do NOT bury the rhizome! This is the single most common mistake beginners make, and it’s the one sure way to kill this otherwise hardy plant.
The rhizome is the thick, horizontal green stem from which the leaves and roots grow. It’s like the plant’s main artery. Burying it in the substrate will cause it to suffocate and rot, leading to the plant’s demise. Instead, Anubias must be attached to a surface where the rhizome is exposed to the water column.
Step 1: Prepare Your Plant and Hardscape
First, choose your anchor. Anubias looks fantastic attached to driftwood, lava rock, or any other textured hardscape. Gently remove the plant from its pot and wash away the rock wool or growing medium from its roots. You can trim any dead or damaged roots, but be careful not to damage the rhizome.
Step 2: Choose Your Attachment Method (Glue vs. Thread)
You have two main options for attaching your Anubias, and both follow anubias aquarium plant facts best practices.
- Super Glue Gel: This is the fastest method. Use a cyanoacrylate-based gel super glue (like Gorilla Glue Gel). It’s completely aquarium-safe once cured. Simply dab a few small dots of glue onto the hardscape, press the rhizome firmly against it for about 30 seconds, and you’re done!
- Fishing Line or Cotton Thread: A more traditional method. Gently wrap a dark-colored fishing line or cotton thread around the rhizome and the object you’re attaching it to. Tie it securely but not so tightly that it cuts into the rhizome. Over time, the plant’s roots will grip the surface, and you can eventually remove the thread (or cotton thread will dissolve on its own).
Step 3: Secure the Rhizome (But Never Bury It!)
Place your newly attached Anubias into your aquarium. The fine, stringy roots can be tucked into the substrate for extra stability, but ensure the thick, green rhizome stays completely above the gravel or sand. It needs to breathe!
Your Complete Anubias Aquarium Plant Facts Care Guide
Once you’ve mastered the planting technique, the rest is easy. This plant’s care requirements are simple and flexible, making it a joy to keep. This section is your go-to anubias aquarium plant facts care guide for long-term success.
Lighting: Less is More
Anubias evolved under the canopy of rainforests, so it prefers low to moderate lighting. In fact, placing it under high-intensity light is one of the few ways to cause problems, as it encourages algae to grow on its slow-growing leaves.
If you have a high-tech tank with powerful lights, place your Anubias in a shaded area, perhaps under a larger piece of driftwood or taller plants. For most standard aquarium light kits, anywhere in the tank will be just fine.
Water Parameters: A Forgiving Nature
Anubias is not picky. It will thrive in a wide range of water conditions, which is another reason it’s so popular.
- Temperature: 72-82°F (22-28°C)
- pH: 6.0-8.0
- Hardness: Soft to hard water (3-15 dGH)
Don’t stress about hitting these numbers exactly. The key is maintaining a stable environment. As long as your tank is suitable for fish, your Anubias will almost certainly be happy.
Fertilization and CO2: Optional but Appreciated
Anubias pulls most of its nutrients directly from the water column through its roots and rhizome. It does not require a nutrient-rich substrate or CO2 injection to survive.
However, it will appreciate a little boost! Dosing a comprehensive liquid fertilizer once or twice a week will result in more robust growth and deeper green leaves. While not necessary, adding CO2 will also encourage healthier, albeit still slow, growth.
Common Problems with Anubias (and How to Fix Them!)
Even the toughest plants can run into issues. Luckily, understanding these common problems with anubias aquarium plant facts makes them easy to solve. Most issues are related to algae or the one fatal planting mistake.
The #1 Enemy: Anubias Algae
Because Anubias leaves grow so slowly and last for a long time, they provide the perfect, stable surface for algae to colonize. The most common culprits are Green Spot Algae (GSA) and Black Beard Algae (BBA).
- The Cause: Too much light and/or an imbalance of nutrients in the water.
- The Fix: First, reduce your lighting period to 6-8 hours per day. Second, ensure you have good water flow around the plant. Third, consider adding algae-eating crew members like Nerite snails, Amano shrimp, or Siamese Algae Eaters. For stubborn spots, you can perform a spot treatment by dabbing a bit of liquid carbon (like Seachem Excel) directly onto the algae with the filter turned off for a few minutes.
Yellowing Leaves: A Sign of Nutrient Deficiency
If you notice the older leaves on your Anubias turning yellow, it’s often a sign of a nutrient deficiency, typically nitrogen or iron. While the plant can survive on fish waste alone, it sometimes needs a little more to truly thrive.
The Fix: Start dosing a quality all-in-one liquid fertilizer. This will provide the necessary micronutrients and macronutrients to keep the leaves lush and green. Don’t worry—the yellowed leaves may not recover, but new growth should come in healthy.
Rhizome Rot: The Only Real Killer
This is the most serious issue and goes back to our golden rule. If the rhizome is buried, it will begin to turn soft, mushy, and brown. This is rhizome rot, and it will spread and kill the entire plant if not addressed.
The Fix: If you catch it early, immediately un-bury the rhizome. Using a sharp, clean blade, carefully cut away any soft or brown parts of the rhizome. You can then re-attach the healthy remaining section to hardscape. If the entire rhizome is mushy, the plant is unfortunately not salvageable.
Exploring the Wonderful World of Anubias Varieties
One of the best parts about Anubias is the incredible variety available. From tiny nano plants to massive statement pieces, there’s an Anubias for every tank size and style.
Anubias barteri var. nana: The Classic Choice
This is the quintessential Anubias. It’s medium-sized, incredibly hardy, and features beautiful, deep green, spade-shaped leaves. It’s the perfect all-rounder for any aquarium.
Anubias nana ‘Petite’: The Tiny Titan
If you have a nano tank or want to create fine details in your aquascape, Nana Petite is your best friend. Its leaves are often smaller than a dime, making it perfect for foregrounds or attaching to small twigs of driftwood.
Anubias coffeefolia: The Textured Beauty
This variety is a showstopper. Its new leaves emerge in a light coffee-brown color and darken to green with age. The leaves have a unique, deeply ridged texture between the veins, adding incredible dimension to your aquascape.

As the name suggests, this one is for larger tanks. With leaves that can grow over a foot long, Anubias gigantea makes a stunning background plant that can create a true jungle feel.
Sustainable and Eco-Friendly Anubias Practices
Being a responsible aquarist also means thinking about sustainability. Fortunately, Anubias makes it easy to practice sustainable anubias aquarium plant facts in your own home.
Propagating Your Own Anubias
Why buy new plants when you can make your own? Propagating Anubias is incredibly simple and is one of the most eco-friendly anubias aquarium plant facts. Once your plant’s rhizome has grown long and has at least 6-8 healthy leaves, you can divide it.
-
Carefully remove the plant from the tank.
-
Using a clean razor blade or sharp scissors, make a clean cut through the rhizome.
-
Ensure each new section has at least 3-4 healthy leaves.
-
That’s it! You now have two plants that you can attach to new pieces of hardscape.
Choosing Your Source Wisely
When you do purchase new plants, consider buying from sources that offer tissue-cultured specimens. These plants are grown in a sterile lab environment, guaranteeing they are 100% free of pests, snails, and algae. This prevents the introduction of unwanted hitchhikers into your carefully balanced ecosystem.
Frequently Asked Questions About Anubias Aquarium Plant Facts
Do Anubias need fertilizer?
Anubias can survive without added fertilizer, especially in a tank with a healthy fish load that provides nutrients via waste. However, to see them truly thrive with vibrant green leaves and steady growth, dosing a comprehensive liquid fertilizer is highly recommended.
Can Anubias grow floating?
While it won’t die immediately, Anubias is not a true floating plant. It will do much better when its roots are anchored to a surface like driftwood or rock, allowing it to remain stable and absorb nutrients more effectively. Leaving it to float long-term is not ideal for its health.
Why are my Anubias leaves turning yellow?
Yellowing leaves, especially older ones, are most commonly a sign of a nutrient deficiency. It’s the plant’s way of saying it’s hungry! This can usually be corrected by adding a good all-in-one liquid fertilizer to your water change routine.
What fish won’t eat Anubias?
Great news! The tough, waxy, and slightly bitter leaves of Anubias make it unpalatable to most fish. It’s one of the few plants that can be kept successfully with notorious plant-eaters like African Cichlids and Goldfish, making it an invaluable choice for those types of tanks.
