Anubias Nana Aquarium Plant – The Ultimate Guide To The Hobby’s Most Versatile Plant

If you’ve ever felt the frustration of watching a beautiful aquatic plant turn into a pile of brown mush within a week, you aren’t alone. Keeping a lush, green tank often feels like a full-time job that requires a degree in chemistry.

But what if I told you there’s a plant that actually thrives on a bit of neglect and looks stunning in almost any setup? The anubias nana aquarium plant is the “secret weapon” of the aquascaping world, offering a vibrant green aesthetic without the high-maintenance demands of delicate stem plants.

In this guide, I’ll walk you through everything from the “no-bury” rule to keeping those leaves algae-free. Whether you are a beginner or a pro, you’ll learn how to make this plant the centerpiece of your underwater world.

What Makes Anubias Nana So Special?

Originating from the shaded streams of West Africa, this plant has adapted to survive in conditions where other plants would simply give up. It is a rhizomatous plant, meaning it grows from a thick, horizontal stem called a rhizome.

Unlike many other species, it doesn’t need to be rooted in the soil to survive. In fact, its ability to cling to rocks and driftwood makes it one of the most versatile tools in an aquarist’s kit.

It is incredibly slow-growing, which is actually a benefit. You won’t find yourself reaching for the trimming scissors every weekend just to keep your tank from becoming an overgrown jungle.

The Anatomy of the Plant

The most recognizable feature is the dark green, heart-shaped leaves. These leaves are tough and leathery, making them unappealing to many herbivorous fish that would otherwise snack on your greenery.

The roots grow downward from the rhizome, seeking out crevices in hardscape rather than burrowing deep into the substrate for nutrients.

This unique structure allows the plant to be positioned in the foreground, midground, or even attached to vertical surfaces to create a sense of depth.

How to Successfully Grow the Anubias Nana Aquarium Plant

The most important rule I can give you is this: never bury the rhizome. This is the single most common mistake beginners make, and it almost always leads to the plant rotting away.

The rhizome needs constant water flow around it to exchange gases and absorb nutrients. If you bury it under sand or gravel, it will eventually suffocate and die.

Instead, you should think of this plant as an “epiphyte.” In nature, it grows on the surfaces of stones or fallen logs, and you should replicate that in your aquarium.

Methods for Securing Your Plant

You have several options for “planting” without actually using substrate. One of my favorite tricks is using a tiny drop of cyanoacrylate-based super glue gel.

Simply pat the rhizome and the rock or wood dry, apply a small dot of glue, and press the plant into place for thirty seconds. It is completely aquarium-safe once cured.

If you prefer a more traditional approach, you can use dark-colored cotton thread or thin fishing line to tie the plant down. Over a few months, the roots will wrap around the surface, and you can eventually snip the thread away.

Substrate Considerations

While the rhizome must stay above the ground, the thin, white roots can definitely find their way into the substrate. This is actually fine and can help the plant anchor itself more firmly.

If you choose to place it near the bottom, just let the roots dangle into the gravel while keeping the “main trunk” clearly visible on the surface.

Light and Water Requirements

One of the biggest draws of the anubias nana aquarium plant is its ability to flourish in low-light environments. In fact, it often performs better in shaded areas than under intense, high-end LED fixtures.

Because it grows so slowly, high light often encourages the growth of nuisance algae on its broad, static leaves. If you have a high-tech tank, try placing your Anubias under the shade of a larger plant or a piece of overhanging driftwood.

Standard “kit” lights that come with most aquariums are usually more than enough to keep this species happy.

Water Parameters for Peak Health

This plant is incredibly adaptable, but it truly thrives when kept in stable conditions. It can handle a wide range of temperatures, typically from 72°F to 82°F (22°C to 28°C).

The pH level is also flexible, though it prefers slightly acidic to neutral water (6.0 to 7.5). As long as you are performing regular water changes to keep nitrates in check, your plant will be just fine.

Hardness isn’t a major factor for this species, making it an excellent choice for hobbyists in areas with “liquid rock” tap water or those using RO/DI systems.

Do You Need CO2 and Fertilizers?

The short answer is no. This plant is a low-tech superstar. It will grow perfectly well without supplemental Carbon Dioxide.

However, adding a basic liquid fertilizer once a week can help maintain that deep green color and prevent the leaves from becoming pale or yellow.

If you notice small holes in the leaves, it might be a sign of potassium deficiency. A quick dose of an all-in-one liquid fertilizer usually clears this right up.

Propagating Your Anubias Collection

One of the most rewarding parts of keeping the anubias nana aquarium plant is how easy it is to create “free” plants for your other tanks.

Propagation is as simple as dividing the rhizome. All you need is a sharp, sterilized pair of scissors or a razor blade.

Look for a healthy section of the rhizome that has at least three or four leaves attached. Simply make a clean cut through the horizontal stem.

The “Set and Forget” Propagation Method

Once you have your two pieces, treat the new cutting just like a full-sized plant. Attach it to a new piece of hardscape and let it do its thing.

Because it grows slowly, don’t expect to see new leaves immediately. It might take a few weeks for the plant to “wake up” and start producing new growth from the cut end.

I’ve found that the mother plant often responds to being cut by sending out multiple new growth points, eventually resulting in a much bushier, denser look.

Common Problems and Troubleshooting

Even the hardiest plants can run into trouble. The most common issue I see with Anubias is Black Beard Algae (BBA) or green spot algae growing on the leaves.

Because the leaves stay in the tank for a long time without being replaced, they become a prime target for algae. If this happens, don’t panic.

You can perform a “spot treatment” by using a syringe to apply a small amount of Seachem Excel or 3% Hydrogen Peroxide directly to the affected leaves during a water change.

Dealing with Rhizome Rot

If you notice the rhizome turning soft, mushy, or translucent, you are likely dealing with rot. This usually happens if the plant was buried or if it experienced a massive shock in water chemistry.

The best course of action is to remove the plant and cut away the mushy parts with a clean blade. If there is still a firm, green section of rhizome left, it can often be saved.

Rinse the healthy portion in clean treated water and re-attach it to a spot with better water circulation.

Yellowing Leaves

Yellow leaves are usually a sign of a nutrient deficiency or old age. If it’s just one of the oldest leaves at the back of the plant, simply snip it off at the base.

If new leaves are coming out yellow, you likely need to increase your liquid fertilization routine. Iron and potassium are the two most common culprits here.

The Best Tank Mates for Anubias Nana

One of the reasons I recommend the anubias nana aquarium plant so often is its compatibility with almost every type of fish.

Because the leaves are so tough, even notorious “plant destroyers” like Goldfish and large Central American Cichlids usually leave them alone.

They can’t easily tear the foliage, and the bitter taste of the leaves acts as a natural deterrent.

Shrimp and Invertebrates

If you are a shrimp keeper, this plant is a must-have. The broad leaves provide a perfect platform for biofilm to grow, which serves as a constant buffet for Cherry Shrimp and Crystal Reds.

The intricate root system also provides excellent hiding spots for shrimplets after they hatch, increasing their survival rate in community tanks.

Snails also love to crawl over the leaves, cleaning off any dust or organic debris that settles on the surface.

Community Fish

For a standard community tank, Anubias provides a sense of security for shy species like Otocinclus cats or Pygmy Corydoras.

I often see my Otos parked right on top of an Anubias leaf, camouflaged perfectly against the dark green surface.

Betta fish also love these plants. The broad leaves of the nana variety provide a perfect “hammock” near the surface where a Betta can rest and breathe easily.

Varieties of Anubias Nana to Explore

While the standard variety is the most famous, there are several cultivars that offer different looks for your aquascape.

Anubias Nana ‘Petite’ is a tiny version that is perfect for nano tanks. Its leaves are often no larger than a fingernail, making it ideal for creating a sense of scale in small setups.

Anubias Nana ‘Golden’ offers a striking lime-green or yellowish hue. It provides a beautiful contrast against the dark greens and browns of a typical scape.

Then there is the Anubias Nana ‘Pinto’, which features white variegation on the leaves. This variety is much slower growing and requires slightly more light to maintain its white patterns, but it is a true showstopper.

Frequently Asked Questions (FAQ)

Can I plant Anubias Nana in the sand?

You can place the roots in the sand, but you must keep the rhizome above the surface. If the thick horizontal stem is covered by sand, it will rot and the plant will die.

How fast does Anubias Nana grow?

It is a very slow grower. Depending on your light and nutrient levels, you might only see one new leaf every 2 to 4 weeks. This makes it very easy to maintain.

Why are there holes in my Anubias leaves?

Holes are often a sign of a potassium deficiency or physical damage from fish. If the holes have yellow edges, it’s likely a nutrient issue that can be fixed with liquid fertilizer.

Does Anubias Nana need a heater?

Yes, it is a tropical plant. While it can survive in cooler water for a short time, it prefers temperatures between 72°F and 82°F. It will grow much better in a stable, heated environment.

Can I grow Anubias Nana out of the water?

Yes! It is an amphibious plant. As long as the humidity is very high and the roots stay wet, it can grow emersed. This makes it a popular choice for paludariums and terrariums.

How do I get rid of algae on the leaves?

The best way is to reduce your lighting period or move the plant to a shadier spot. You can also gently scrub the leaves with a soft toothbrush during water changes.
