How To Maintain Anubias Plant – For Thriving, Low-Maintenance

Have you ever brought home a stunning Anubias, with its deep green, waxy leaves, only to watch it languish? Maybe it’s covered in stubborn algae, or its growth has stalled completely. It’s a frustratingly common story for many aquarists, and you’re definitely not alone.

But here’s the good news: Anubias is one of the most forgiving and rewarding plants in the hobby. You just need to know its secrets. With a few simple adjustments, you can unlock its true potential and turn it into the lush, vibrant centerpiece your aquarium deserves.

This is your complete how to maintain anubias plant care guide. We’re going to walk through everything, step-by-step. We’ll cover the single most important rule of planting, dial in the perfect environment, and tackle those pesky problems like algae head-on. By the end, you’ll have the confidence and knowledge to grow beautiful, healthy Anubias for years to come.

Why Anubias is an Aquarist’s Best Friend (And Worth Maintaining!)

Before we dive into the “how,” let’s talk about the “why.” Understanding the benefits of how to maintain anubias plant specimens will make the little effort required feel incredibly rewarding. These plants are true champions of the underwater world for several reasons.

First, they are incredibly resilient. Hailing from the streams and marshes of Africa, they are built to last. They tolerate a wide range of water parameters, making them perfect for beginners who are still learning to keep their tank stable. Don’t worry—these plants are perfect for beginners!

They are also true low-light superstars. You don’t need a high-tech, expensive lighting rig to make them happy. This flexibility allows you to place them in shadier spots of your aquascape where other plants might struggle.

Finally, their tough, leathery leaves are a major plus. Most herbivorous fish, like many cichlids and even goldfish, tend to leave them alone. This makes Anubias a beautiful and durable choice for tanks where more delicate plants would quickly become a snack.

The Golden Rule: How to Plant Anubias Correctly

If you remember only one thing from this entire guide, let it be this: Do NOT bury the rhizome! This is the absolute number one mistake aquarists make with Anubias, and it’s a guaranteed way to kill an otherwise healthy plant.

What is a Rhizome?

The rhizome is the thick, horizontal stem from which the leaves and roots grow. Think of it as the plant’s central artery. It needs to be exposed to the water column to breathe and absorb nutrients. Burying it in your substrate (like sand or gravel) will cause it to suffocate, rot, and decay.

How to Attach Your Anubias

Instead of planting it in the substrate, you should attach your Anubias to something. Hardscape like driftwood, lava rock, or slate are perfect anchors. Here’s how to do it:

  1. Prepare the Plant: Gently remove the plant from its pot and rock wool. Rinse away any remaining wool from the roots. You can trim any dead or mushy roots, but leave the healthy ones.
  2. Choose Your Method: You have a couple of fantastic, easy options.
    • Super Glue Gel: A dab of aquarium-safe cyanoacrylate super glue gel (like Loctite Gel Control) is the quickest method. Pat the rock or wood and the rhizome dry, apply a small amount of glue, and press them together for 30-60 seconds. You can place it in the tank immediately.
    • Fishing Line or Thread: You can also tie the plant to the hardscape using a dark-colored fishing line or cotton thread. Wrap it a few times around the rhizome and the object until it’s secure. Over time, the plant’s roots will grip the surface, and you can eventually remove the thread (or cotton thread will dissolve on its own).
  3. Place it in the Tank: Position your newly mounted Anubias in its desired spot. The roots can hang freely in the water or grow down into the substrate, which is perfectly fine—just keep that rhizome above ground!

Creating the Perfect Environment: Water, Lighting, and Flow

Once planted correctly, Anubias is quite adaptable. However, giving it an environment where it can truly thrive is key. This is a core part of our how to maintain anubias plant guide.

Ideal Water Parameters

Anubias isn’t fussy, which is fantastic. It will do well in a wide range of conditions, but here’s the sweet spot to aim for:

  • Temperature: 72-82°F (22-28°C)
  • pH: 6.0 – 7.5
  • Hardness (GH): 3 – 10 dGH

Stability is more important than hitting these exact numbers. Avoid sudden, drastic swings in your water chemistry.

Getting Lighting Just Right

Anubias is famous for being a “low-light” plant, but this can be a bit misleading. While it survives in low light, it thrives in low-to-moderate light. The real danger is too much light.

Intense, direct lighting is the primary cause of the stubborn Green Spot Algae that often plagues Anubias leaves. Because the plant grows so slowly, algae has plenty of time to take hold under bright lights. Aim for a PAR value of around 15-30 at the plant’s level, or simply place it in a shaded area of your tank, perhaps under floating plants or larger stem plants.

Gentle Flow is Key

Anubias appreciates gentle to moderate water flow. Good circulation brings nutrients directly to the plant’s leaves and roots and, just as importantly, prevents debris and detritus from settling on the leaves, which can smother the plant and encourage algae growth.

A Complete Guide on How to Maintain Anubias Plant Nutrition

Thinking about how to maintain anubias plant health long-term means thinking about food. Like any living thing, Anubias needs nutrients to grow, even if its appetite is small.

Do Anubias Need Fertilizer?

Yes, but sparingly. Anubias are slow growers and primarily “epiphytes,” meaning they pull most of their nutrition from the water column through their leaves and roots, not from the substrate.

A good quality, comprehensive liquid fertilizer is your best bet. A weekly dose of a product like Seachem Flourish or Aquarium Co-Op Easy Green will provide the necessary micro and macronutrients. Because they grow so slowly, you can often get away with a half-dose compared to what you’d use for faster-growing stem plants.

The CO2 Question

Injecting carbon dioxide (CO2) is absolutely not necessary for Anubias. They will grow perfectly well in a low-tech setup without it. However, adding CO2 can act like a turbo-boost, encouraging slightly faster, more robust growth and a deeper green coloration. If you already run CO2 for other plants, your Anubias will certainly benefit, but don’t feel you need to add it just for them.

Pruning and Propagation: The Secret to a Bushy, Healthy Plant

Regular maintenance keeps your Anubias looking its best and allows you to create new plants for free! This is where you can embrace sustainable how to maintain anubias plant practices.

How to Prune for Health

Over time, older leaves may turn yellow or become covered in algae. This is normal. Using a pair of sharp aquascaping scissors, simply snip the stem of the unwanted leaf as close to the rhizome as possible. This redirects the plant’s energy to producing new, healthy growth.

Propagating Anubias: The Gift That Keeps on Giving

Propagating Anubias is incredibly easy and a fantastic, eco-friendly how to maintain anubias plant tip. It allows you to fill out your aquascape or share with friends without buying new plants.

  1. Select a Healthy Plant: Choose a mature plant with a long rhizome and plenty of leaves.
  2. Make the Cut: Using a sharp blade or scissors, make a clean cut through the rhizome.
  3. Divide and Conquer: Ensure each new section has at least 3-4 healthy leaves. A piece of rhizome with no leaves will likely not survive.
  4. Re-attach: Attach your new, smaller plants to new pieces of rock or driftwood just as you did with the original. That’s it! You’ve just created new life.

Troubleshooting: Common Problems with How to Maintain Anubias Plant

Even with the best care, you might run into an issue or two. Don’t panic! Here are the most common problems and how to solve them.

The Battle with Algae (Especially Green Spot Algae)

This is the number one complaint. Hard green spots on the leaves are almost always caused by too much light and not enough phosphates.
Solution: Reduce your lighting intensity or duration. Move the plant to a shadier spot. Ensure you have good water flow. For manual removal, you can gently scrub the leaves with a soft-bristled toothbrush during a water change. Adding phosphate-removers can make it worse; often, a slight increase in phosphates (via fertilizer) can help plants outcompete this type of algae.

Decoding Yellow Leaves

A single older leaf turning yellow and dying off is normal. If multiple leaves, especially new ones, are turning yellow, it’s likely a nutrient deficiency.
Solution: This often points to a lack of nitrogen or iron. Start dosing a comprehensive liquid fertilizer if you aren’t already, or slightly increase your current dose. Ensure your other water parameters are stable.

The Dreaded Rhizome Rot

If you notice the rhizome is becoming soft, mushy, and brown, you’re likely dealing with rot.
Solution: This is almost always caused by the rhizome being buried. Immediately un-bury it. With a sharp blade, carefully cut away any soft, mushy parts of the rhizome back to healthy, firm tissue. Re-attach the healthy portion to a rock or piece of wood. If caught early, the plant can often be saved.

Frequently Asked Questions About Anubias Care

Why are my new Anubias leaves smaller than the old ones?

This is very common. Plants are often grown emersed (out of water) at nurseries, which results in larger leaves. When you submerge the plant in your aquarium, its new “submersed” growth will naturally be smaller and more compact. This is a sign of healthy adaptation!

Can I plant Anubias in sand or gravel?

You can let the roots grow down into the sand or gravel, but you must never bury the rhizome. The rhizome must always remain on top of the substrate, exposed to the water.

How fast does Anubias grow?

Extremely slowly! You might only see one new leaf every month or two. This is perfectly normal. Patience is a virtue with this plant, but its slow growth is also what makes it so low-maintenance.

What fish are safe with Anubias?

Almost all of them! The leaves are very tough and bitter-tasting to most fish. Even notorious plant-eaters like many African Cichlids, Silver Dollars, and Goldfish will typically leave Anubias alone, making it one of the most universally “fish-proof” plants available.
