Written ByHoward Parker

Ever feel like finding the perfect aquarium plant is a quest? You’re looking for something beautiful, hardy, and something that actually helps your fish thrive. It can feel like you need a degree in botany just to keep a simple plant alive underwater.

I’m here to tell you, as a fellow aquarist who has been through it all, that your search is over. The solution is a stunning, near-indestructible plant from West Africa called Anubias.

I promise that by the end of this guide, you’ll see why this plant is a superhero in the aquascaping world. We’ll explore the incredible anubias plant aquarium benefits, from its tank-cleaning power to its forgiving nature. You’ll learn exactly how to plant it, the best care practices to make it flourish, and how to troubleshoot any little bumps along the road. Let’s get growing!

What Makes Anubias the Aquarist’s Best Friend?

Before we dive into the nitty-gritty, let’s get properly acquainted. Anubias is a genus of aquatic and semi-aquatic flowering plants native to the tropical rivers and streams of central and western Africa. In the wild, they often grow attached to rocks and logs, sometimes fully submerged and sometimes with their leaves in the open air.

This tells us something crucial about them: they are tough. They are built to withstand changing water levels, currents, and varying light conditions.

For us in the aquarium hobby, this translates into a plant that is incredibly forgiving. They are characterized by their thick, dark green leaves, a sturdy stem-like structure called a rhizome, and strong, wiry roots. They are slow growers, which might sound like a downside, but it’s actually one of their greatest strengths for creating a stable, low-maintenance setup.

The Top 7 Anubias Plant Aquarium Benefits for a Healthier Ecosystem

So, why should you rush out and get an Anubias for your tank? The list of reasons is long, but I’ve distilled it down to the most impactful benefits. This is more than just a pretty green decoration; it’s a functional workhorse for your aquatic environment.

  1. Natural Water Filtration

    Like all live plants, Anubias acts as a tiny, living filter. It actively absorbs nitrates and other nitrogen compounds from the water column. These compounds are the end-product of fish waste and uneaten food, and in high concentrations, they can be harmful to your fish.

    By using these nitrates as fertilizer, your Anubias helps keep the water cleaner and healthier, reducing the stress on your fish and potentially extending the time between water changes. This is one of the most crucial eco-friendly anubias plant aquarium benefits you can get.

  2. Algae-Resistant Leaves

    Now, no plant is completely algae-proof, but Anubias comes close to being algae-resistant. Its leaves are thick, waxy, and tough. This texture makes it difficult for many types of algae to get a strong foothold, especially compared to more delicate, feathery plants.

    This is a huge plus for beginners who are often battling those early-tank algae blooms. With the right care (which we’ll cover!), your Anubias leaves will stay clean and deep green.

  3. Provides Shelter and Security for Fish and Shrimp

    Watch your tank after adding a broad-leafed Anubias. You’ll quickly see your fish and shrimp interacting with it. The wide, umbrella-like leaves provide excellent cover for shy or nocturnal species like certain tetras, rasboras, or Corydoras catfish.

    For shrimp and baby fish (fry), these plants are a five-star hotel. They offer countless surfaces to graze for biofilm and a safe haven to hide from larger, more boisterous tank mates. A secure fish is a happy and healthy fish!

  4. Oxygenates the Water

    It’s a simple fact of biology, but one worth remembering. Through the process of photosynthesis, Anubias releases oxygen into the water during the day. This helps create a more stable, oxygen-rich environment for your fish and the beneficial bacteria in your filter.

  5. Incredibly Hardy and Forgiving

    This is the benefit that makes Anubias a legend. It doesn’t demand much. It thrives in low to moderate light, doesn’t require CO2 injection, and isn’t picky about water parameters. It can handle a wide range of temperatures, pH levels, and water hardness.

    Did you forget to dose fertilizer this week? Your Anubias will be fine. Is your light not the most expensive, high-tech model? Don’t worry—Anubias will still grow. This resilience makes it the perfect plant for anyone just starting their journey with live plants.

  6. Versatile Aquascaping Options

    Because Anubias is an epiphyte—meaning it grows attached to surfaces rather than in the substrate—your aquascaping possibilities are endless. You aren’t limited to planting it in the sand or gravel.

    You can attach it to driftwood for a natural, aged look. You can wedge it between rocks to create a stunning focal point. You can even create entire walls or backgrounds using multiple plants. This versatility allows for incredible creativity in your tank design.

  7. A Sustainable and Cost-Effective Choice

    Anubias grows slowly but steadily. Over time, its rhizome will lengthen and sprout new leaves. You can easily propagate it by simply cutting the rhizome into sections (making sure each has a few leaves) and reattaching the new pieces. One plant can eventually turn into many, for free!

    This slow growth also means you won’t be constantly trimming and removing excess plant matter, making it a key part of achieving sustainable anubias plant aquarium benefits in a low-maintenance tank.

A Simple Anubias Plant Aquarium Benefits Care Guide

Ready to bring one home? Fantastic! Following this simple anubias plant aquarium benefits care guide will ensure your new green friend thrives for years to come.

Lighting: Less Is More

This might sound counterintuitive, but Anubias actually prefers low to moderate lighting. If the light is too intense or left on for too long (more than 8-10 hours a day), its slow-growing leaves become a prime target for stubborn spot algae.

A standard LED light that comes with most aquarium kits is often perfect. You don’t need a high-powered light system to keep this plant happy.

Water Parameters: The “Go With the Flow” Plant

Anubias is wonderfully adaptable. It’s happy in a wide range of conditions, which is why it suits almost any community tank.

  • Temperature: 72-82°F (22-28°C)
  • pH: 6.0-7.5
  • Hardness: Soft to moderately hard water

Don’t stress about hitting these numbers exactly. The key is maintaining a stable environment. Anubias dislikes rapid changes more than anything else.

Fertilization: A Light Snacker

Because Anubias primarily pulls nutrients from the water through its roots and leaves, a nutrient-rich substrate isn’t necessary. A good quality, comprehensive liquid fertilizer dosed once or twice a week is more than enough to provide the micronutrients it needs to stay lush and green.

CO2 Injection: Optional but Appreciated

You absolutely do not need to inject CO2 to grow Anubias. It will grow perfectly well without it. However, if you have a high-tech setup with CO2, you will notice slightly faster and more robust growth. Think of it as a welcome bonus, not a requirement.

How to Plant Anubias for Maximum Benefits (And Avoid a Common Mistake!)

Okay, this is one of the most important sections of this guide. There is one golden rule when it comes to planting Anubias, and breaking it is the number one reason these “indestructible” plants die.

The Golden Rule: DO NOT BURY THE RHIZOME!

The rhizome is the thick, horizontal part of the plant from which the leaves and roots grow. It looks like a thick green stem. This part of the plant needs to be exposed to the water column. If you bury it under your sand or gravel, it will be deprived of oxygen and will quickly rot, killing the entire plant.

The Best Ways to Attach Your Anubias

So, how do you plant it correctly? You attach it to something! Here are a few tried-and-true methods that deliver the best results. This is how to anubias plant aquarium benefits your tank’s aesthetic from day one.

  1. The Super Glue Method

    This is my personal favorite for its speed and security. Use a gel-type super glue containing cyanoacrylate (most brands are aquarium-safe once cured, but check the label!). Pat the spot on the rock or driftwood dry, apply a small dab of glue to the plant’s roots or the very bottom of the rhizome, and press it onto the surface for 30 seconds. You can place it back in the water immediately.

  2. The Fishing Line or Thread Method

    A classic technique. Simply use a dark-colored fishing line or cotton thread to tie the rhizome securely (but not too tightly) to your hardscape. Over a few months, the plant’s roots will grow and grip the surface on their own. If you use cotton thread, it will eventually dissolve and disappear, leaving the plant naturally attached.

  3. The Wedge Method

    This requires no extra materials! Look for natural cracks and crevices in your driftwood or rocks. You can often gently wedge the rhizome or roots of the Anubias into these spots. The pressure will hold it in place until its roots can take a firm hold.

Common Problems with Anubias and Easy Solutions

Even the toughest plants can run into issues. Don’t panic! Here are some common problems with anubias plant aquarium benefits and how to fix them with simple tweaks.

Problem: Algae on the Leaves

Cause: Almost always, this is caused by too much light. It could be that your light is too intense, or you’re leaving it on for too many hours a day.

Solution: Reduce your lighting period to 6-8 hours. If possible, dim your light or raise it higher above the water. You can also introduce algae-eating crew members like Nerite snails, Amano shrimp, or Otocinclus catfish, who love to clean Anubias leaves.

Problem: Yellowing Leaves

Cause: If new leaves are yellow, it could be a sign of an iron deficiency. If older leaves are yellowing and dying off one by one, it might be a nitrogen deficiency or simply the end of that leaf’s natural life cycle.

Solution: Start by dosing a comprehensive liquid fertilizer that contains both macro- and micronutrients. Pruning the occasional old, yellow leaf is normal and encourages new growth.

Problem: Rhizome Rot

Cause: The rhizome was accidentally buried in the substrate, or the plant is in a “dead spot” in the tank with very poor water circulation.

Solution: Act fast! Carefully lift the plant and inspect the rhizome. Trim away any parts that are soft, brown, and mushy using a clean razor blade or scissors. Re-attach the healthy portion of the rhizome to a rock or piece of wood and place it in an area with better water flow.

Frequently Asked Questions About Anubias Plant Aquarium Benefits

What are the best types of Anubias for beginners?

While almost all are great, Anubias barteri var. nana (often just ‘Anubias Nana’) is the king. It’s small, compact, and exceptionally hardy. ‘Anubias Nana Petite’ is an even smaller version perfect for nano tanks, and ‘Anubias Coffeefolia’ has beautifully textured leaves.

Can Anubias grow in a tank without substrate?

Yes, absolutely! Because they are epiphytes that get attached to hardscape, they are a perfect choice for bare-bottom tanks, which are common for breeding or quarantine purposes. They get all they need from the water itself.

How fast does Anubias grow?

Very, very slowly. You might only see one new leaf every few weeks. While this might disappoint those looking for rapid growth, it’s a huge benefit for aquarists who want a beautiful, stable aquascape without the need for constant trimming and maintenance.

What fish are safe to keep with Anubias?

Almost any fish! The leaves are so tough and bitter-tasting that even notorious plant-eaters like Goldfish and some African Cichlids will often leave them alone. They are perfectly safe for all community fish, shrimp, and snails.

Your Thriving Aquarium Awaits

From its water-purifying abilities to its indestructible nature, the benefits of the Anubias plant are clear. It’s not just a plant; it’s a partner in creating a stable, healthy, and beautiful underwater world.

It provides shelter for your fish, asks for very little in return, and gives you incredible creative freedom in your aquascape. It is, without a doubt, one of the best plants you can choose, whether you are setting up your very first tank or are a seasoned veteran looking for a reliable green companion.

So, are you ready to add this incredible plant to your aquarium? Trust me, your fish will thank you, and you’ll fall in love with the lush, vibrant life it brings to your tank. Go forth and create your underwater paradise!
