Written ByHoward Parker

Have you ever dreamed of a lush, green aquarium but felt intimidated by the thought of complicated plant care? You see stunning aquascapes online and wish you could create that same vibrant underwater world, but worry you don’t have the time, equipment, or a “green thumb.”

I’m here to let you in on a little secret the pros love: the Anubias nana. This nearly indestructible plant is the answer you’ve been searching for. It’s the perfect starting point for beginners and a reliable favorite for seasoned aquarists.

This comprehensive guide promises to walk you through everything you need to know. We’ll cover the single most important rule of planting, the ideal tank conditions, and how to solve common problems before they start. By the end of this article, you’ll have the confidence and knowledge for successful anubias nana plant care and be well on your way to a thriving, beautiful aquarium.

What Makes Anubias Nana the Perfect Aquarium Plant?

Before we dive into the “how-to,” let’s talk about the “why.” Understanding the benefits of anubias nana plant care helps you appreciate just how incredible this little plant is. It’s not just popular because it looks good; it’s loved because it makes your life as an aquarium keeper so much easier.

I’ve used Anubias in countless tanks, from simple betta setups to complex community aquariums, and it never fails to impress. It’s the workhorse of the aquascaping world.

Here’s why you’ll love it:

  • Incredibly Hardy: This plant is tough as nails. It can tolerate a wide range of water conditions, making it forgiving for beginners who are still learning to balance their tank’s chemistry.
  • Low Light Champion: You don’t need expensive, high-intensity lighting. Anubias nana thrives in low to moderate light, which means it’s perfect for basic aquarium kits and can be placed in shadier spots in your tank.
  • Slow and Steady Growth: Unlike stem plants that need constant trimming, Anubias nana grows very slowly. This means less maintenance for you and a consistent look for your aquascape.
  • Doesn’t Need Substrate: It’s an epiphyte, which means it grows attached to things like driftwood and rocks rather than in gravel or sand. This gives you incredible creative freedom!
  • Fish-Friendly: Its leaves are thick, waxy, and durable, so it can stand up to even boisterous fish like cichlids or curious goldfish that might nibble on more delicate plants.

The Golden Rule of Planting Anubias: Don’t Bury the Rhizome!

If you take only one piece of advice from this entire anubias nana plant care guide, let it be this. The single biggest mistake beginners make is treating Anubias like a typical plant and burying its base in the substrate. This will, without a doubt, kill your plant.

Anubias has a thick, horizontal stem called a rhizome. It’s the part from which both the leaves (upwards) and roots (downwards) grow. This rhizome needs to be exposed to the water column to breathe and absorb nutrients. Burying it will cause it to rot, a condition often called “anubias melt,” and the plant will fall apart.

So, how do you plant it correctly? You attach it to hardscape! Here are the two best methods:

Using Super Glue (Cyanoacrylate Gel)

This is my favorite method—it’s fast, easy, and secure. Don’t worry, it’s completely aquarium-safe once cured!

  1. Gather your supplies: your Anubias plant, a piece of driftwood or rock, and a tube of cyanoacrylate gel super glue (gel works better than liquid).
  2. Pat the spot on your hardscape and the rhizome of the plant dry with a paper towel. The glue sets faster on a dry surface.
  3. Apply a few small dabs of gel glue to the hardscape.
  4. Press the rhizome firmly onto the glue and hold for about 30-60 seconds.
  5. You can place it directly back into the aquarium! The roots will eventually grow and wrap around the object, anchoring it permanently.

Using Fishing Line or Cotton Thread

This is a more traditional method that works just as well. It’s one of the classic anubias nana plant care best practices.

  1. Place your Anubias rhizome against the desired spot on your rock or wood.
  2. Take a piece of dark cotton thread or thin fishing line and wrap it around the hardscape and over the rhizome several times.
  3. Tie it off securely but not so tightly that you crush the rhizome.
  4. Over a few months, the plant’s roots will attach themselves. By then, the cotton thread will have dissolved, or you can carefully snip the fishing line away.

Your Complete Anubias Nana Plant Care Guide: Tank Parameters

Now that you know how to plant it, let’s create the perfect environment. The good news is, “perfect” for Anubias nana is incredibly flexible. This plant isn’t demanding, but dialing in these conditions will ensure it doesn’t just survive—it thrives.

Lighting Requirements

Anubias is the king of low-tech tanks. It prefers low to moderate lighting. If you blast it with high-intensity light, you’re not doing it any favors. In fact, its slow-growing leaves become a prime target for stubborn green spot algae under bright light. Stick to a standard kit light or a lower setting on an adjustable LED, and your plant will be much happier.

Water Parameters (pH, Temp, Hardness)

This is where its hardiness really shines. While it has ideal ranges, it can adapt to most typical community tank conditions.

  • Temperature: 72-82°F (22-28°C)
  • pH: 6.0-7.5
  • Hardness (GH): It’s not picky, but it does well in a wide range from soft to hard water.

Basically, if your fish are happy, your Anubias will almost certainly be happy too. Consistency is more important than chasing a perfect number.

Fertilization Needs

As an epiphyte, Anubias nana is a “water column feeder.” This means it pulls most of its nutrients directly from the water through its roots and rhizome, not from the substrate. In a well-stocked aquarium, fish waste provides a steady supply of nitrates and phosphates.

For truly lush growth, however, a comprehensive liquid fertilizer dosed once or twice a week is beneficial. Look for one that contains micronutrients like iron and potassium. This is a key part of sustainable anubias nana plant care, as a healthy, well-fed plant is more resistant to algae and disease.

CO2 Injection: Necessary or Optional?

Completely optional. Anubias nana does perfectly fine without any CO2 injection, making it a star player for low-tech setups. If you do run CO2 for other, more demanding plants in your tank, your Anubias will certainly benefit with slightly more robust growth, but it is by no means a requirement.

Common Problems with Anubias Nana Plant Care (And How to Fix Them)

Even the toughest plants can run into issues. Fortunately, the common problems with anubias nana plant care are usually easy to diagnose and fix. Here’s what to look out for.

Problem: Algae on the Leaves

This is the most common issue. Because the leaves grow so slowly, they provide a stable, sunlit surface for algae to colonize. The usual culprit is Green Spot Algae.

  • Cause: Too much light intensity or duration, and sometimes a phosphate imbalance.
  • Solution: Reduce your lighting period to 6-8 hours per day. If possible, dim the light’s intensity. Introduce an algae-eating crew! Nerite snails are fantastic at cleaning Anubias leaves, as are Amano shrimp and Otocinclus catfish.

Problem: Yellowing Leaves

Seeing a yellow leaf can be alarming, but it’s often not a big deal.

  • Cause: It could simply be an old leaf dying off naturally as the plant produces new growth. However, if multiple leaves are turning yellow, it likely points to a nutrient deficiency, often nitrogen or iron.
  • Solution: Gently remove the old, dying leaf. Start dosing a comprehensive liquid fertilizer to ensure the plant is getting all the micronutrients it needs.

Problem: Rhizome is Black and Mushy (Rhizome Rot)

This is the most serious issue and, unfortunately, often fatal if not caught early.

  • Cause: The rhizome was buried in the substrate or was damaged during planting.
  • Solution: Immediately unearth the plant. With a sharp, sterile blade, cut away any black, mushy parts of the rhizome. If you have a healthy section with leaves remaining, you may be able to save it by re-attaching it to hardscape. Prevention is the best cure here—always keep that rhizome above the substrate.

How to Propagate Anubias Nana: More Plants for Free!

One of the most rewarding parts of keeping Anubias is how easy it is to propagate. You can turn one plant into many over time, filling out your aquascape or sharing with fellow hobbyists. This is the heart of eco-friendly anubias nana plant care!

Follow these simple steps:

  1. Carefully remove the mother plant from your aquarium.
  2. Identify the rhizome. You’ll see it’s a long, creeping stem.
  3. Using a clean razor blade or sharp scissors, make a clean cut through the rhizome.
  4. Ensure each new section has at least 3-4 healthy leaves. A piece with fewer leaves may struggle to survive.
  5. That’s it! You now have two or more plants. Attach the new pieces to rocks or driftwood just as you did with the original, and place them back in your tank.

Frequently Asked Questions About Anubias Nana Plant Care

Does Anubias nana need fertilizer?

In a tank with fish, it can often survive on the nutrients from fish waste alone. However, to see it truly thrive with deep green leaves and steady growth, dosing a comprehensive liquid fertilizer once or twice a week is highly recommended.

Why are my Anubias nana leaves turning yellow?

The most common reason is that it’s simply an old leaf at the end of its life cycle. If many leaves are yellowing at once, it’s likely a nutrient deficiency. Check your fertilization routine and ensure your plant is getting essential micronutrients like iron.

Can I plant Anubias nana in gravel or sand?

Absolutely not! This is the most critical rule. You must never bury the rhizome (the thick, horizontal stem) in the substrate. Doing so will cause it to rot and kill the plant. Always attach Anubias to driftwood, rocks, or decorations.

How fast does Anubias nana grow?

It grows very, very slowly. You might only see one new leaf every 3-5 weeks. This is a major advantage for aquarists who want a low-maintenance setup, as it rarely requires any trimming.
