Anubias Plant Aquarium Care Rhizome – The Ultimate Guide To Avoiding
Have you ever bought a beautiful, lush Anubias plant, carefully planted it in your substrate like any other plant, only to watch it slowly turn yellow, mushy, and die? It’s a frustrating experience so many of us in the aquarium hobby have faced.
If you’re nodding along, I promise you’re not alone, and it’s not your fault. The secret to success with this incredible plant isn’t in the leaves or the roots—it’s all about understanding one crucial part: the rhizome.
This comprehensive guide will unlock everything you need to know about anubias plant aquarium care rhizome management. We’ll dive into what a rhizome is, the single most important rule for keeping it healthy, and the best practices for planting, care, and even propagation.
Get ready to transform your Anubias from merely surviving to absolutely thriving. Let’s grow something amazing together!
What Exactly is an Anubias Rhizome (And Why It’s the Key to Success)?
Before we get into the “how-to,” let’s cover the “what.” Think of the rhizome as the plant’s central nervous system. It’s the thick, horizontal green or brown stem from which both the leaves (upward) and the roots (downward) grow.
It’s not a root! This is the most common misunderstanding. Unlike plants that bury their roots for nutrients, the Anubias rhizome functions like an anchor and a storage unit. It needs to be exposed to the open water to breathe and absorb nutrients directly from the water column.
When you bury the rhizome under gravel or sand, you essentially suffocate it. It can’t perform gas exchange, leading to the dreaded “rhizome rot,” which is almost always fatal for the plant. Remembering this one fact is 90% of the battle won.
The Golden Rule: How to Plant Your Anubias the Right Way
So, if you can’t bury it, what do you do? The beauty of Anubias is its versatility. You don’t plant it in your aquascape; you attach it to your aquascape. This is where the fun begins, allowing you to add greenery to rocks, driftwood, and other decorations.
Here are the two most popular and effective methods for securing your Anubias, ensuring its rhizome stays safe and healthy.
Method 1: The Super Glue Method
Don’t worry—this is completely safe for your fish and invertebrates! The key is to use the right kind of glue. You’ll want a gel-type super glue containing 100% Cyanoacrylate. The gel consistency makes it much easier to work with than the runny liquid version.
First, pat the Anubias rhizome and the spot on your rock or driftwood dry with a paper towel. The glue works best on a dry surface.
Apply a few small dabs of the gel super glue onto the hardscape where you want to place the plant.
Press the rhizome firmly onto the glue spots and hold for about 30-60 seconds until it sets. You don’t need to glue the entire length; a few strategic points are enough.
You can place it directly back into the aquarium! The glue cures instantly underwater and becomes completely inert and safe.
Method 2: The Fishing Line or Thread Method
This is a classic method that works perfectly, especially for larger plants or awkwardly shaped driftwood. It’s a fantastic, eco-friendly anubias plant aquarium care rhizome technique.
Position your Anubias on the desired piece of decor.
Take a piece of dark-colored cotton thread or thin fishing line and wrap it around the driftwood/rock and the rhizome several times to secure it firmly.
Tie a secure knot and trim any excess line. Be careful not to tie it so tightly that you damage the rhizome.
Over several months, the plant’s roots will grow and wrap themselves around the decor, anchoring the plant permanently. If you use cotton thread, it will eventually dissolve and disappear on its own!
Can You Place Anubias on Substrate?
Yes, but with a major catch. You can gently tuck the thin, stringy roots into the substrate to help anchor it, but the thick, green rhizome must sit on top of the gravel or sand, fully exposed to the water. You can place a small stone on a root to hold it down while it establishes itself.
Your Complete Anubias Plant Aquarium Care Rhizome Guide
Once your Anubias is properly secured, the rest is incredibly simple. This is why it’s a beginner’s favorite! This section of our anubias plant aquarium care rhizome guide covers the basic parameters to ensure lush, healthy growth.
Lighting Needs
Anubias are low-light champions. They thrive in shaded areas of the tank, under floating plants, or in aquariums with low to moderate lighting. In fact, too much direct, intense light can be a problem.
High light encourages algae to grow on its slow-growing leaves. If you have a high-tech tank, place your Anubias in a spot where taller plants or hardscape can provide some shade. This is one of the most important anubias plant aquarium care rhizome tips to keep your leaves looking pristine.
Water Parameters and Fertilization
These plants are tough as nails and aren’t picky about water conditions. They are adaptable to a wide range of parameters, making them suitable for almost any tropical community tank.
Temperature: 72-82°F (22-28°C)
pH: 6.0-8.0
Hardness: Soft to hard water is acceptable.
Because they are “epiphytes” that feed from the water column, they will benefit from a comprehensive liquid fertilizer. Dosing a liquid fertilizer once or twice a week will provide all the necessary micronutrients to keep their leaves deep green and healthy. CO2 injection is not required, but it will certainly encourage more robust growth.
Propagating Anubias: How to Multiply Your Prized Plant
One of the best benefits of anubias plant aquarium care rhizome knowledge is how easy it is to create new plants for free! If your Anubias is growing long and healthy, you can easily propagate it.
Simply take a pair of sharp, clean aquarium scissors or a razor blade and cut the rhizome. Ensure each new piece you create has at least 3-4 healthy leaves attached. That’s it! You now have a brand new, independent plant that you can attach elsewhere in your tank or share with a friend.
This process is a cornerstone of sustainable anubias plant aquarium care rhizome practices, allowing you to fill out your aquascape without constantly buying new plants.
Troubleshooting: Common Problems with Anubias Plant Aquarium Care Rhizome
Even the hardiest plants can run into issues. Don’t worry—most are easy to diagnose and fix. Here are some common problems you might encounter.
The Dreaded Rhizome Rot
This is the number one killer of Anubias. If you notice the rhizome is soft, mushy, and turning black or brown, it’s likely rotting. This is almost always caused by being buried in the substrate.
The Fix: Act fast! Remove the plant from the tank and use a sharp blade to cut away all the mushy, rotted parts of the rhizome. If you have any healthy sections left (firm and green/white inside) with leaves, you might be able to save them. Let the cut end “scab over” in the air for an hour before re-attaching it in your tank—properly this time!
Yellowing Leaves
If you see a leaf turning yellow, don’t panic immediately. It could just be an old leaf at the end of its life cycle, which is perfectly normal. However, if multiple leaves are turning yellow, it often points to a nutrient deficiency, typically iron. Dosing a good-quality liquid fertilizer should resolve this.
Algae Growing on Leaves
Because Anubias leaves grow so slowly and last for a long time, they can become a prime surface for algae, especially spot algae. This is usually a sign of too much light or an imbalance of nutrients in the water.
The Fix:
Reduce your lighting period or intensity.
Ensure you are performing regular water changes.
Introduce an algae-eating crew! Nerite snails, Amano shrimp, and Otocinclus catfish love to graze on Anubias leaves without harming them.
For stubborn algae, you can gently wipe the leaves with your finger or a soft toothbrush during a water change.
The Benefits of Anubias: More Than Just a Pretty Plant
Incorporating Anubias into your aquarium offers more than just visual appeal. Here are a few of the top benefits:
Extremely Hardy: They are forgiving and perfect for beginners who are still learning.
Low-Light Tolerant: They bring life and color to darker corners of your tank where other plants might fail.
Provides Shelter: The broad leaves offer excellent hiding and resting spots for shy fish, fry, and shrimp.
Versatile Aquascaping: Attaching them to hardscape opens up endless creative possibilities for your layout.
Slow Growth: This means less maintenance and trimming for you!
Frequently Asked Questions About Anubias Plant Care
Can Anubias survive just floating in the tank?
Yes, for a while. It’s not ideal for the long term as it may not get stable light and can be tossed around by the current. It’s always better to attach it to something so its roots can anchor and the plant can establish itself properly.
How fast does Anubias grow?
Very slowly! You might only see one new leaf every few weeks or even per month. This is completely normal. Patience is key with Anubias, but its slow, steady growth is part of its low-maintenance charm.
Why are the new leaves on my Anubias smaller than the old ones?
This can be a sign that the plant is still acclimating to your tank’s conditions, especially if it was grown emersed (out of water) at the nursery. It can also indicate a lack of nutrients. Ensure you’re providing a good liquid fertilizer, and with time, the new leaves should grow to their full potential.
What fish are safe to keep with Anubias?
Almost all of them! Anubias leaves are famously tough and leathery, which makes them resistant to most herbivorous fish like goldfish and many cichlids. They are a fantastic choice for tanks where other, more delicate plants would be eaten.
Go Forth and Grow!
You now hold the single most important piece of information for Anubias success: never, ever bury the rhizome.
By understanding how this amazing plant works and giving its rhizome the access to open water it needs, you’ve overcome the biggest hurdle. You’re now equipped with the best practices for planting, care, and troubleshooting, ready to create a stunning, thriving underwater garden.
So grab some super glue or thread, pick a beautiful piece of driftwood, and give your Anubias the home it deserves. Happy scaping!
