Written ByHoward Parker

Are you searching for that perfect, lush green plant to create a stunning carpet or accent in your aquascape, but worried about complicated care routines? It’s a common feeling. Many beautiful aquarium plants demand high light, CO2 injection, and constant attention, which can feel overwhelming.

I’m here to tell you there’s a better way. The secret to a gorgeous, low-effort foreground is a tiny powerhouse of a plant: Anubias barteri var. nana ‘Mini’, or as we lovingly call it, Anubias Nana Mini. This is the plant that lets you have a professional-looking aquascape without the professional-level workload. This complete guide provides everything you need for successful anubias nana mini care.

We’ll walk through everything together. You’ll learn the one crucial rule for planting, how to provide the perfect (and easy!) environment, and how to solve the few small problems you might encounter. By the end, you’ll have all the confidence and knowledge you need to grow this amazing plant.

What Makes Anubias Nana Mini So Special?

Before we dive into the “how-to,” let’s talk about the “why.” Understanding the benefits of anubias nana mini care helps you appreciate just how incredible this little plant is. It’s a favorite among beginners and seasoned aquascapers for very good reasons.

First, it’s incredibly resilient. Think of it as the ironclad hero of the plant world. It tolerates a huge range of water parameters, making it forgiving for those of us who are still learning or have less-than-perfect water chemistry. Don’t worry—this plant is perfect for beginners!

Here are a few more reasons why it deserves a spot in your tank:

  • Perfect Size: As its name suggests, this is a true dwarf variety. Its small, deep green leaves are perfect for nano tanks or for creating detailed foregrounds in larger aquariums. It adds a sense of scale and intricacy.
  • Low Light Champion: Unlike many carpeting plants, Anubias Nana Mini thrives in low to moderate light. This means you don’t need an expensive, high-tech lighting system to see it flourish.
  • Slow and Steady Growth: Its slow growth rate is a massive advantage. You won’t be constantly trimming it back every week. It stays compact and beautiful with minimal intervention.
  • Fish Friendly: The tough, leathery leaves are generally ignored by most herbivorous fish, including many cichlids and goldfish that would make a snack out of more delicate plants.

Getting Started: How to Plant Anubias Nana Mini Correctly

Okay, friend, this is the most important section of the entire guide. If you get this one step right, you are 90% of the way to success. The most common mistake beginners make is treating Anubias like a typical stem plant, and it’s a fatal one.

The key to understanding how to anubias nana mini care starts with its anatomy. Anubias plants have a thick, horizontal stem called a rhizome. The leaves and roots grow directly from this rhizome. Here is the golden rule:

Never, ever bury the rhizome.

Burying the rhizome in your substrate (like sand or gravel) will cause it to rot, and the plant will slowly die. Instead, you need to attach it to something above the substrate. This is much easier than it sounds!

H3: Attaching to Hardscape (The Best Method)

Your best bet is to attach your Anubias Nana Mini to a piece of driftwood, a rock, or even a decoration. This mimics how it grows in the wild, attached to rocks and logs in shaded streams.

  1. The Super Glue Gel Method (My Favorite): This is the quickest and cleanest way. Get some aquarium-safe super glue gel (any brand based on cyanoacrylate is fine). Pat the plant’s rhizome and the spot on the rock/wood dry with a paper towel. Apply a few dabs of glue to the rhizome and press it firmly onto the hardscape for 30-60 seconds. You can place it back in the water immediately!
  2. The Fishing Line or Thread Method: A more traditional approach. Simply use a dark-colored cotton thread or a clear fishing line to gently tie the rhizome to your chosen surface. Over a few months, the plant’s roots will grow and anchor themselves firmly. You can then snip and remove the thread if you wish.

The Ultimate Anubias Nana Mini Care Guide: Light, CO2, and Nutrients

Now that your plant is securely in its new home, let’s talk about keeping it happy. The good news is, this part is incredibly simple. This plant’s needs are minimal, making this anubias nana mini care guide one of the easiest you’ll ever follow.

Lighting Requirements: The “Low-Light Lover”

Anubias evolved under the canopy of rainforests, in the shade. It wants the same in your aquarium. It is a true low-light plant. Too much intense, direct light will not make it grow faster; it will just make it a target for stubborn algae.

Aim for low to moderate lighting. If you have a powerful light, place the Anubias in a shaded area of your tank—under a larger plant’s leaves or in the shadow of a piece of driftwood. This is one of the most important anubias nana mini care tips to prevent algae issues.

CO2: Necessary or Nice-to-Have?

Here’s more great news: CO2 injection is not required. Your Anubias Nana Mini will grow perfectly well without any supplemental CO2. It’s one of the reasons it’s such a star in low-tech setups.

That said, if you already have a high-tech tank with CO2 running for other plants, your Anubias will appreciate it. You might notice slightly faster, more robust growth, but it’s purely a bonus, not a necessity.

Fertilization: Simple Feeding for a Happy Plant

Anubias are what we call “water column feeders.” They primarily absorb nutrients through their leaves and roots directly from the water, not from the substrate (which is another reason burying the rhizome is a bad idea!).

A simple, all-in-one liquid fertilizer dosed once or twice a week is more than enough. Look for a comprehensive fertilizer that contains both macronutrients (Nitrogen, Phosphorus, Potassium) and micronutrients. Don’t overdo it—these are slow-growing plants with a low appetite.

Common Problems with Anubias Nana Mini Care (and How to Fix Them)

Even the toughest plant can run into a few hiccups. Fortunately, the common problems with anubias nana mini care are few and have simple solutions. Let’s troubleshoot.

Problem 1: Algae on the Leaves

This is, by far, the most common issue. Because the leaves are tough and grow slowly, they provide a perfect surface for algae to settle on, especially spot algae or stubborn Black Beard Algae (BBA).

  • The Cause: Almost always too much light. It can also be caused by an imbalance of nutrients or fluctuating CO2 levels.
  • The Fix: First, reduce your lighting intensity or duration. Try leaving the lights on for 6-8 hours per day. Second, ensure you are performing regular water changes and not over-fertilizing. You can manually remove algae by gently rubbing the leaves or spot-treating with liquid carbon (like Seachem Excel) with the filter turned off for a few minutes.

Problem 2: Yellowing Leaves (Chlorosis)

If you notice the leaves, especially new ones, turning pale or yellow, your plant is likely hungry.

  • The Cause: A nutrient deficiency, most commonly a lack of iron or other micronutrients.
  • The Fix: This is a straightforward fix. Start dosing a comprehensive liquid fertilizer that contains iron and other trace elements. You should see new leaves coming in a healthy, deep green.

Problem 3: Rotting Rhizome

If the rhizome feels soft and mushy and the leaves are falling off at the base, you’re dealing with rhizome rot.

  • The Cause: The rhizome was buried in the substrate, or the plant is suffering from a severe infection.
  • The Fix: If you catch it early, you can sometimes save the plant. Remove it from the tank and, with a sharp, clean blade, cut away any soft, brown, or mushy parts of the rhizome until you only have firm, healthy green tissue left. Re-attach the healthy portion to hardscape and hope for the best.

Propagation: How to Multiply Your Anubias Nana Mini

One of the best parts of growing Anubias is how easy it is to create new plants. This is the heart of sustainable anubias nana mini care—you may never have to buy another one again!

Once your plant’s rhizome has grown long and has at least 6-8 healthy leaves, you can propagate it. It’s as simple as giving it a haircut.

  1. Remove the Plant: Take the parent plant out of the aquarium.
  2. Find Your Cutting Point: Look for a natural place to divide the rhizome. You want to ensure each new piece has at least 3-4 healthy leaves attached.
  3. Make the Cut: Using a sharp razor blade or aquascaping scissors, make a clean cut through the rhizome. Don’t use a dull tool, as crushing the rhizome can lead to rot.
  4. Re-plant: That’s it! You now have two (or more) separate Anubias Nana Mini plants. Attach them to hardscape just like you did with the original.

Eco-Friendly and Sustainable Anubias Nana Mini Care Best Practices

Being a responsible aquarist means thinking about our impact. Practicing eco-friendly anubias nana mini care is easy and rewarding. It’s all about making conscious choices that benefit your tank and the environment.

One of the best practices is to source your plants responsibly. Whenever possible, buy tank-grown plants from local hobbyists or reputable stores. This reduces the demand for wild-harvested plants and minimizes the risk of introducing pests or diseases.

Propagating your own plants, as we just discussed, is sustainability in action. Instead of buying new plants, you can grow your own supply. You can even trade your extra cuttings with other hobbyists in your local aquarium club or online community, fostering a circular economy within the hobby. This is one of the most fulfilling aspects of keeping these plants.

Frequently Asked Questions About Anubias Nana Mini Care

Can Anubias Nana Mini grow in sand or gravel?

No, you should not plant the rhizome directly into any substrate, including sand or gravel. Burying the rhizome will cause it to rot. You must attach the plant to rocks or driftwood, allowing the roots to grow down into the substrate if they choose, but keeping the rhizome exposed to the water column.

Why are the leaves on my Anubias turning yellow?

Yellowing leaves are typically a sign of a nutrient deficiency. Anubias are slow feeders, but they still need access to nutrients from the water. Dosing a good all-in-one liquid fertilizer regularly should solve the problem and encourage new, healthy green growth.

How fast does Anubias Nana Mini grow?

It grows very slowly. You might only see one or two new leaves per month. This is completely normal and is one of its best features! It means less maintenance for you and a plant that won’t outgrow its space quickly.

Do I need to trim Anubias Nana Mini?

You generally do not need to trim it for size control. The only trimming required is to remove any old leaves that have turned yellow or become covered in algae that you can’t remove. Simply snip the leaf stem as close to the rhizome as possible.
