It’s a common challenge many of us face.
I promise you, you don’t have to give up on your dream of a green, vibrant tank. There’s a nearly indestructible, gorgeous plant that is perfect for sand substrates, but only if you know the one crucial secret to its survival.
In this complete can anubias nana grow in sand guide, we’re going to unlock that secret. We’ll walk through exactly how to plant Anubias nana in sand to avoid common pitfalls, explore the fantastic benefits, troubleshoot any issues, and share some pro tips to help you create a stunning, sustainable underwater garden. Let’s dive in!
The Short Answer: Yes! But There’s a Crucial Catch
Let’s get straight to the point: Yes, you can absolutely grow Anubias nana in a sand substrate. In fact, it can look absolutely stunning, with its deep green leaves creating a beautiful contrast against light-colored sand.
However, there is one non-negotiable, golden rule you must follow, and it’s the reason so many beginners accidentally kill this otherwise hardy plant. It all comes down to a part of the plant called the rhizome.
The rhizome is the thick, horizontal stem-like part of the Anubias where the leaves and roots sprout from. Think of it as the plant’s central artery. If you bury this rhizome under the sand, it will be smothered, unable to exchange gases, and will quickly begin to rot, killing the entire plant.
So, the big secret is simple: NEVER, EVER BURY THE RHIZOME. As long as you keep that rhizome above the sand, your Anubias will not only survive, but it will thrive.
Understanding Anubias: Why Sand Requires a Special Technique
To really master how to grow Anubias nana in sand, it helps to understand a little about the plant’s nature. Anubias are epiphytes, a fancy word that simply means they are accustomed to growing on top of other surfaces in the wild—like rocks, logs, and tree roots along riverbanks.
Their roots are primarily used for anchoring themselves, not for absorbing nutrients from the substrate like a traditional stem plant. They pull most of their nutrition directly from the water column through their leaves and rhizome.
This is why sand can be tricky. Its fine particles can easily pack tightly around the rhizome, cutting off its access to oxygen and flowing water. Unlike gravel, which has larger gaps, sand offers no breathing room. This is why a specific planting technique is not just a suggestion—it’s essential for the plant’s long-term health.
How to Plant Anubias Nana in Sand the Right Way: A Step-by-Step Guide
Alright, let’s get our hands wet! Forget everything you know about pushing plants into the substrate. Here are the two best methods for successfully planting your Anubias in a tank with sand. This is one of the most important sections in any can anubias nana grow in sand care guide.
Method 1: Attaching to Hardscape (The Gold Standard)
This is the most natural and foolproof method. By attaching your Anubias to a piece of driftwood or a rock, you mimic its natural environment and completely eliminate the risk of burying the rhizome.
Prepare Your Plant: Gently remove your Anubias nana from its pot and any rock wool. Rinse it thoroughly under lukewarm tap water to remove any debris.
Gather Your Tools: You’ll need your Anubias, a piece of driftwood or a rock, and an attachment material. Your best options are either aquarium-safe super glue gel (like Cyanoacrylate gel) or a dark-colored cotton thread/fishing line.
The Super Glue Method: Pat the rhizome and the spot on your hardscape dry with a paper towel. Apply a few small dots of super glue gel to the underside of the rhizome. Press it firmly onto the rock or wood for about 30-60 seconds until it holds.
The Tying Method: If using thread or line, simply wrap it around the rhizome and the hardscape a few times until the plant is secure. Don’t tie it so tight that you crush the rhizome! Cotton thread will dissolve over a few months, by which time the plant’s roots will have attached themselves.
Place in Your Aquarium: Gently place your newly mounted Anubias anywhere you like in your tank. You can nestle it into the sand, letting the roots dangle and eventually grow down into the sand to anchor it further. The rhizome stays safe and sound, high and dry above the substrate.
Method 2: The “Floating Anchor” Technique
What if you want the look of the plant emerging directly from the sand without it being attached to a large piece of decor? This method is for you. It keeps the rhizome safe while giving the illusion of a planted Anubias.
Find a Small Anchor: Grab a small, flat piece of rock, a ceramic plant weight, or even a large piece of gravel. It just needs to be heavy enough to hold the buoyant plant down.
Attach the Plant: Using the same super glue or tying method described above, secure the Anubias rhizome to your small anchor weight.
Position on the Sand: Now, simply place the weighted plant on the surface of your sand. Gently press the anchor down so it’s just barely covered by a thin layer of sand, ensuring the entire rhizome is still exposed to the water.
Let the Roots Do the Work: Over the coming weeks and months, the Anubias roots will grow down from the rhizome and burrow into the sand, anchoring the plant permanently and creating a beautiful, natural look.
The Amazing Benefits of Growing Anubias Nana in Sand
Once you master the planting technique, you’ll discover why this combination is so popular. The benefits of can anubias nana grow in sand go far beyond just looking good.
Stunning Aesthetics: The deep, waxy green leaves of Anubias nana create a striking visual contrast against bright white or natural-colored sand. It makes the colors pop and adds a touch of elegance.
Perfect for Low-Tech Tanks: Anubias nana is not a demanding plant. It thrives in low-to-moderate lighting and doesn’t require CO2 injection, making it a fantastic choice for beginner-friendly, low-maintenance setups.
Incredibly Hardy: These plants are tough as nails! Their thick, leathery leaves are unappealing to most plant-eating fish (like many cichlids and even goldfish), so they stay looking pristine.
Provides Shelter for Fauna: The broad leaves offer excellent resting spots and hiding places for shrimp, snails, and small, shy fish. It’s a functional piece of decor that improves your inhabitants’ quality of life.
Easy Maintenance: Since it’s not rooted in the substrate, you can easily move it around during tank cleanings or redesigns without creating a cloudy mess.
Common Problems with Anubias Nana in Sand and Easy Fixes
Even the toughest plants can run into trouble. Don’t worry—most issues are easy to diagnose and fix. Here are some common problems with can anubias nana grow in sand and how to solve them.
Problem: The Rhizome is Turning Mushy and Black
This is the classic, number-one issue: rhizome rot. It’s almost always caused by the rhizome being buried. The fix requires immediate action. Carefully lift the plant, trim away any soft, black, or smelly parts of the rhizome with sterile scissors, and re-attach it to a rock or piece of wood where it will be fully exposed to the water.
Problem: Leaves are Turning Yellow
Yellowing leaves, especially older ones, typically point to a nutrient deficiency. Sand is an inert substrate, meaning it contains no nutrients. Since Anubias feeds from the water, this is a sign your water is lacking key minerals. The solution is to start dosing a comprehensive liquid fertilizer once or twice a week after your water change.
Problem: Pesky Algae is Growing on the Leaves
Because Anubias nana grows so slowly, its leaves are prime real estate for algae, especially Green Spot Algae or Black Beard Algae. This is usually caused by too much light. Anubias prefers shaded, low-light conditions. Try reducing your lighting duration to 6-8 hours per day or moving the plant to a shadier spot in the tank. Adding algae-eating crew members like Amano shrimp, Nerite snails, or Otocinclus catfish can also work wonders.
Pro Tips for Sustainable Anubias Nana Care in a Sand Substrate
Ready to take your Anubias game to the next level? Follow these can anubias nana grow in sand best practices for long-term success and a truly thriving plant.
Go Easy on the Light: Less is more. High light won’t make Anubias grow faster; it will just make algae grow faster on its leaves. Place it under floating plants or in the shadow of larger hardscape for the best results.
Feed the Water, Not the Sand: Forget root tabs. They do nothing for Anubias. Invest in a quality, all-in-one liquid fertilizer and dose it consistently. This is the key to vibrant, healthy leaves.
Promote Gentle Water Flow: Good circulation is vital. It delivers nutrients directly to the plant’s leaves and rhizome and helps prevent algae and debris from settling on them. Just avoid placing it directly in the powerful blast of a filter outlet.
Propagate for Free Plants: One of the best parts of sustainable can anubias nana grow in sand care is how easy it is to propagate. Once your rhizome has grown long and has at least 6-8 healthy leaves, you can snip it in half with clean scissors. Attach both pieces to new surfaces, and just like that, you have two plants! It’s an eco-friendly way to fill out your tank without spending more money.
Frequently Asked Questions About Growing Anubias Nana in Sand
Do I need root tabs for Anubias in sand?
Nope! This is a common misconception. Root tabs are for plants that feed heavily through their roots, like Cryptocoryne or Sword plants. Anubias is an epiphyte that primarily absorbs nutrients from the water column. A good liquid fertilizer is all you need.
Can the roots of Anubias go into the sand?
Yes, and they should! It’s perfectly fine and even desirable for the roots to grow down into the sand. They will help anchor the plant securely. The key is that the rhizome—the thick horizontal part the leaves grow from—must always stay above the sand.
How fast does Anubias nana grow in sand?
Anubias nana is a famously slow-growing plant, regardless of the substrate. In a healthy, stable aquarium, you can expect to see a new leaf emerge every few weeks. Its slow growth is part of its appeal, as it means less pruning and maintenance for you!
What kind of sand is best for an Anubias nana tank?
Since the Anubias isn’t planted directly in the sand, any aquarium-safe sand will work perfectly well. Your choice of sand should be based more on the aesthetic you prefer and the needs of any bottom-dwelling fish you have, like Corydoras catfish, who appreciate a soft, fine grain.
Your Journey to a Greener Tank Starts Now
So, can anubias nana grow in sand? The answer is a resounding YES. It’s not about the substrate being “right” or “wrong”; it’s all about the technique.
By remembering the single most important rule—keep the rhizome out of the sand—you’ve already won half the battle. Attach it to a beautiful piece of driftwood or a textured rock, provide it with gentle light and nutrients from the water, and it will reward you with years of effortless beauty.
Don’t be afraid to experiment with sand in your aquarium. You’ve got the knowledge and the tools to succeed. Go ahead, create that stunning aquascape you’ve been dreaming of. Your Anubias is ready for its new home!
