Understanding the Anubias Nana: Why Its Planting Method is Unique
Before we get to the “how,” we need to understand the “why.” Anubias Nana isn’t like your typical stem plant or Amazon Sword. It belongs to a special group of plants called epiphytes.
Think of epiphytes as the “tree-huggers” of the plant world. In nature, they don’t grow in the muddy riverbed. Instead, they attach themselves to rocks, driftwood, and other surfaces, pulling nutrients directly from the water column through their leaves and roots.
The most important part of an Anubias is its rhizome. This is the thick, horizontal, stem-like part from which both the leaves (growing up) and roots (growing down) emerge. This rhizome acts as a nutrient storage unit and is the life force of the plant. Burying it is the single biggest mistake you can make—it will suffocate, rot, and the plant will perish. The roots are just for anchoring, not for absorbing nutrients from the substrate!
So, Can Anubias Nana Grow in Gravel? The Simple Answer (and the Crucial “How”)
Yes, an Anubias Nana can absolutely grow and thrive in an aquarium with a gravel substrate. In fact, it’s one of the most popular and successful combinations for beginners and experts alike.
However, you don’t “plant” it in the traditional sense. The key is to ensure the rhizome is never buried underneath the gravel. The roots can dip into the gravel for anchorage, but the rhizome must remain exposed to the water column to breathe and absorb nutrients.
This is the core of our can anubias nana grow in gravel guide. Forget everything you know about potting terrestrial plants. Here, we’re aiming for attachment and anchoring, not burial. There are two fantastic, easy methods to achieve this.
Your Step-by-Step Guide: How to Plant Anubias Nana in Gravel Correctly
Ready to get planting? Here are the two best methods to ensure your Anubias is happy and healthy in its new gravel home. This is the practical answer to how to can anubias nana grow in gravel.
Method 1: Attaching to Decor (The Recommended Method)
This is the most natural and foolproof way to plant Anubias. By attaching it to a piece of driftwood or a rock, you mimic its natural environment and guarantee the rhizome stays safe.
-
Gather Your Supplies: You’ll need your Anubias Nana, a piece of aquarium-safe driftwood or rock, and an adhesive. Your best options are either super glue gel (make sure it’s cyanoacrylate-based) or a dark-colored cotton thread/fishing line.
-
Prepare the Plant: Gently remove the Anubias from its pot and rock wool. Rinse it thoroughly under lukewarm tap water to remove any lingering debris. You can trim any dead or mushy-looking roots, but it’s not always necessary.
-
Attach the Plant:
-
Using Super Glue Gel: Dab a few small dots of glue onto the clean, dry rock or driftwood where you want to place the plant. Gently press the rhizome (not the delicate roots) onto the glue dots and hold for about 30-60 seconds until it sets. Don’t worry, the glue is perfectly safe for fish and shrimp once cured!
-
Using Thread: Simply place the rhizome against the decor and wrap the cotton thread or fishing line around it a few times to secure it firmly, but not so tight that you damage it. Cotton thread will dissolve over a few months, by which time the plant’s roots will have naturally attached themselves.
-
-
Place in Your Aquarium: Carefully place your newly decorated piece into your aquarium. Position it on top of the gravel wherever you like. That’s it! You’ve successfully “planted” your Anubias.
Method 2: The “Gravel Anchor” Technique
If you want the look of the Anubias growing directly from your substrate, this method is for you. It’s a bit trickier but still highly effective if done correctly.
-
Prepare the Plant: Follow the same preparation steps as in Method 1, rinsing the plant and removing it from its pot.
-
Find a Spot: Choose a location in your tank. This method works best if you can wedge the plant between a few larger pieces of gravel or near a larger decoration for stability.
-
Gently Anchor the Roots: Hold the Anubias with the rhizome well above the gravel line. Use your fingers or aquascaping tweezers to gently push only the very tips of the roots into the gravel. The goal is to use the gravel to hold the roots in place, which in turn holds the plant down.
-
Check the Rhizome: Double and triple-check that the entire rhizome is sitting on top of the gravel, fully exposed to the water. It should not be covered by even a single pebble. You can also use a plant weight gently wrapped around the roots (never the rhizome!) to help keep it down.
Benefits of Growing Anubias Nana in a Gravel Aquarium

Common Problems with Anubias Nana in Gravel (and How to Fix Them!)
Even the toughest plants can run into issues. Luckily, the common problems with can anubias nana grow in gravel are usually easy to diagnose and fix.
Problem: Rhizome Rot (The #1 Mistake)
Symptoms: The rhizome feels mushy and turns black or brown. Leaves turn yellow near the base and fall off easily.
Cause: The rhizome was buried in the gravel and suffocated.
Solution: Immediately unbury it! Use a clean blade to trim away any soft, rotted parts of the rhizome. If there’s a healthy green section left, it can recover. Re-attach it to decor where it will get good water flow.
Problem: Algae on Leaves
Symptoms: Green or brown fuzzy spots or film covering the beautiful leaves.
Cause: Anubias grows very slowly, making its leaves a prime target for algae, especially in tanks with high light or excess nutrients.
Solution: Reduce your lighting period to 6-8 hours. Manually clean the leaves with a soft brush or your finger during water changes. Introduce an algae-eating crew like Amano shrimp, Nerite snails, or Otocinclus catfish. They love to graze on Anubias leaves without harming them.
Problem: Yellowing Leaves
Symptoms: Older leaves are slowly turning yellow, but the rhizome is firm and healthy.
Cause: This is often a sign of a nutrient deficiency, usually nitrogen or potassium, since the plant can’t get these from the gravel.
Solution: Start dosing a comprehensive liquid fertilizer once or twice a week. This provides all the necessary micronutrients and macronutrients directly into the water column where the Anubias can absorb them.
Best Practices for a Thriving Anubias Nana in Your Gravel Tank
Ready to give your Anubias the best life possible? Follow this simple can anubias nana grow in gravel care guide for lush, long-lasting growth.
-
Lighting: Low to moderate light is the sweet spot. Too much light will only encourage algae to grow on its slow-growing leaves. It’s a perfect plant for lower-tech setups.
-
Fertilization: This is non-negotiable. Since gravel is inert, you must provide nutrients via the water. A good all-in-one liquid fertilizer like Seachem Flourish or Aquarium Co-Op Easy Green is an excellent choice.
-
Water Flow: Gentle water flow is beneficial. It helps deliver nutrients to the plant and prevents detritus from settling on its broad leaves.
-
Placement: Avoid placing it directly under the filter outflow if the current is very strong. Its sturdy leaves can handle a lot, but a gentle flow is always better.
Following these can anubias nana grow in gravel best practices will set you up for years of enjoyment from this wonderful plant.
Frequently Asked Questions About Growing Anubias Nana in Gravel
Do I need fertilizer if I have Anubias Nana in gravel?
Yes, absolutely. Gravel contains no nutrients for plants. Since Anubias Nana is an epiphyte that feeds from the water, you need to add a comprehensive liquid fertilizer to the water column to keep it healthy and green.
Can I just drop Anubias Nana in the tank and let it float?
While it won’t die immediately, it’s not ideal. The plant may get tossed around by the current or end up in a dark corner. It will be much healthier and look far better if you anchor it to a surface or use the gravel anchor method.
What’s the difference between the roots and the rhizome?
This is a great question! The rhizome is the thick, horizontal green part that looks like a stem lying on its side; this is where leaves and roots sprout from. The roots are the thin, wiry, often brownish strands that grow downwards from the rhizome. Their main job is to grip onto surfaces.
Can I trim the roots of Anubias Nana?
Yes, you can. If the roots get overly long or you want a cleaner look, you can trim them without harming the plant. Just be sure you are only trimming the thin roots and never the thick rhizome.
Your Journey to Lush Greenery Starts Now
So, the final verdict is in. Can anubias nana grow in gravel? Not only can it, but it’s one of the most rewarding and low-maintenance ways to create a beautiful, natural-looking aquascape.
The secret, as we’ve learned, isn’t about the gravel itself—it’s about respecting the plant’s nature. By keeping that vital rhizome out in the open water and giving it something to hold onto, you provide everything it needs to flourish.
Don’t be afraid to experiment. Grab a piece of driftwood, some super glue gel, and that gorgeous Anubias. You now have all the expert knowledge you need to create a stunning, thriving underwater garden. Happy scaping!
