Anubias Plant Decaying: Your Step-By-Step Rescue And Prevention Guide
There’s a sinking feeling every aquarist knows. You look at your beautiful Anubias—that tough, “unkillable” plant you were so proud of—and you see it. A mushy, browning base. Leaves that are yellowing and detaching. It’s a sight that can make even a seasoned hobbyist’s heart drop.
You’ve probably heard Anubias are the perfect beginner plant. So why is yours dying? Don’t worry, you’re not alone, and it’s almost certainly not your fault. The problem of an anubias plant decaying is one of the most common issues new aquarists face, and it usually stems from one simple, correctable mistake.
I promise, this guide will not only show you exactly how to diagnose the problem but also give you the confidence to perform a little “plant surgery” to save it. We’ll walk through everything you need to know.
Get ready to transform that decaying plant into a thriving centerpiece. Let’s dive in and fix this together!
Why Your “Bulletproof” Anubias is Decaying: Getting to the Root of the Problem
Anubias has a reputation for being indestructible, and for good reason. It’s hardy, low-light tolerant, and doesn’t ask for much. But it has one critical weakness. Understanding this is the first step in our anubias plant decaying care guide.
The #1 Culprit: Burying the Rhizome
If you take away only one thing from this article, let it be this: Do not bury the Anubias rhizome!
The rhizome is the thick, horizontal green stem from which both the leaves (upward) and roots (downward) grow. Think of it as the plant’s central lifeline. Unlike plants like Amazon Swords or Vallisneria that are planted in the substrate, Anubias is an epiphyte. In nature, it grows attached to rocks and driftwood, not in the mud.
When you bury the rhizome under gravel or sand, you suffocate it. It can’t exchange gases or access nutrients properly, and it begins to rot. This is, without a doubt, the leading cause of an anubias plant decaying.
Anubias Rot: Identifying the Fungal Foe
When the rhizome is damaged or suffocated, it becomes vulnerable to opportunistic bacteria and fungi in your tank. This leads to a condition commonly called “Anubias rot” or “rhizome rot.”
You’ll know it when you see (and smell) it. The affected part of the rhizome will be:
- Soft and mushy to the touch.
- Brown or black in color.
- It may have a distinct, unpleasant rotting smell.
This rot can spread quickly along the rhizome, consuming the entire plant if left unchecked. Addressing these common problems with anubias plant decaying starts with identifying this specific issue.
Poor Water Flow and Stagnant Conditions
While not a direct cause, poor water circulation can make a bad situation worse. Stagnant water allows waste and bacteria to settle on the plant, creating an environment where rot can take hold more easily, especially if the rhizome is already stressed or slightly damaged.
Physical Damage During Planting
The rhizome is tough, but it’s not invincible. If it gets crushed, snapped, or deeply gouged during handling or while you’re moving decor around, that wound creates an open door for infection. Always handle your Anubias gently by its leaves or roots.
Your Emergency Anubias Plant Decaying Guide: A Step-by-Step Rescue Mission
Spotted the dreaded mush? Don’t panic. It’s time to act. If there is any firm, green rhizome left, you have a very good chance of saving your plant. Grab your tools, and let’s get to work.
Gently Remove the Plant: Carefully take the Anubias out of your aquarium. If it’s attached to something, try to remove it without causing more damage. Place it in a shallow dish with some tank water to keep it moist.
Inspect and Assess the Damage: Gently rinse the rhizome under some clean, dechlorinated water. Feel along its entire length. You’re looking for the line between the firm, healthy green tissue and the soft, brown, mushy rot.
Perform “Plant Surgery”: This is the most crucial step. Using a clean, sharp razor blade, scalpel, or pair of aquascaping scissors, you need to cut away all of the rotting tissue. Be ruthless here. Even a tiny bit of rot left behind can spread again. Cut back into the healthy green tissue by a millimeter or two just to be safe. A clean cut on healthy tissue will heal much better.
The Optional Disinfectant Dip: This is an advanced but effective tip. You can create a very mild disinfectant dip to kill any lingering pathogens on the freshly cut surface. A 3-minute dip in a 3% hydrogen peroxide solution is a common method. (Important: Never add hydrogen peroxide directly to your main tank). Rinse the plant thoroughly in fresh, dechlorinated water after the dip.
Re-attach, Don’t Re-bury: Now that you have a clean, healthy piece of rhizome (even if it’s small!), it’s time to put it back in the tank correctly. We’ll cover exactly how to do that in the next section.
The Art of Planting Anubias: Best Practices to Prevent Decay
Prevention is always the best medicine. Following these anubias plant decaying best practices will ensure you never have to deal with rhizome rot again. The goal is simple: keep that rhizome up in the water column.
Attaching to Hardscape: The Gold Standard
The most natural and safest way to plant Anubias is by attaching it to driftwood, rocks, or decorations. This mimics its natural environment and guarantees the rhizome gets the light and flow it needs.
- Super Glue Method: Use a gel-type cyanoacrylate super glue (like Gorilla Glue Gel or Loctite Gel Control). It’s completely aquarium-safe once cured. Pat the rhizome and the attachment spot dry, apply a few small dabs of glue to the rhizome, and press it onto the hardscape for 30-60 seconds. You can place it back in the water immediately.
- Fishing Line or Thread Method: Simply tie the Anubias to the hardscape using a dark-colored cotton thread or fishing line. The thread will dissolve over a few months, by which time the plant’s roots will have anchored it firmly. Fishing line is more permanent but may need to be removed later if you want a cleaner look.
“Planting” in Substrate (The Right Way)
Want the look of Anubias growing from your substrate? You can still do it, but with a crucial modification. You can bury the thin, stringy roots, but the thick, green rhizome must sit on top of the substrate, fully exposed to the water. You can use a small stone to gently weigh it down until the roots take hold.
Long-Term Anubias Care: Creating an Environment Where They Thrive
A healthy, unstressed plant is a resilient plant. Once you’ve mastered the planting technique, a few simple care tips will keep your Anubias lush and green for years to come.
Lighting and Algae Management
Anubias are famous for their low-light tolerance. In fact, they prefer it! Placing them under intense, direct lighting is a recipe for algae growth on their slow-growing leaves. Position them in shaded areas of your tank or under floating plants. If you see green spot algae, your light is likely too intense or on for too long.
Fertilization Needs: Less is More
These plants are not heavy feeders. They pull most of their nutrients directly from the water column through their leaves and roots. Dosing a comprehensive, all-in-one liquid fertilizer once or twice a week is more than enough to meet their needs. Overdoing it will only feed algae.
The Benefits of Healthy Anubias
A thriving Anubias does more than just look good. Its broad leaves provide excellent shelter and grazing surfaces for shrimp and small fish. Like all live plants, it also helps improve water quality by consuming nitrates. These are the real benefits of anubias plant decaying reversal—a healthier, more stable ecosystem.
Sustainable and Eco-Friendly Practices for Anubias Care
Being a responsible aquarist also means thinking about our impact. Embracing a few sustainable anubias plant decaying prevention methods can make your hobby even more rewarding.
Propagate and Share
Once your Anubias is large and healthy, you can easily propagate it. Simply make a clean cut on the rhizome, ensuring each piece has at least 3-4 healthy leaves. This is a fantastic, eco-friendly anubias plant decaying alternative to buying new plants. You can use the new pieces in other tanks or trade them with fellow hobbyists!
Avoid Chemical Overkill
Instead of reaching for harsh algaecides to treat algae on the leaves, focus on the root cause—usually too much light or nutrients. A balanced tank is a healthy tank. Good husbandry is always the most sustainable solution.
Choose Tank-Raised Specimens
Whenever possible, purchase Anubias that are lab-grown or raised by other hobbyists. This reduces the demand for wild-harvested plants, protecting natural ecosystems from which these beautiful species originate.
Frequently Asked Questions About Anubias Plant DecayingCan a rotting Anubias recover?
Absolutely! As long as there is a piece of firm, green, healthy rhizome remaining, you can perform the “surgery” described above to save the plant. It’s surprisingly resilient and will often sprout new leaves from the surviving piece within a few weeks.
Why are my Anubias leaves turning yellow and transparent?
This is typically a separate issue from rhizome rot. Yellowing leaves often point to a nutrient deficiency, most commonly nitrogen or iron. Rhizome rot starts at the base and feels mushy, while a nutrient issue affects the leaf itself, often leaving the rhizome healthy.
Is it okay if the Anubias roots are buried in the substrate?
Yes, that’s perfectly fine! The thin, wiry roots are meant to anchor the plant and can be buried in gravel or sand. It’s only the thick, horizontal rhizome (the part the leaves grow from) that must be kept above the substrate.
How quickly does Anubias rot spread?
It can spread alarmingly fast. Once it takes hold, it can consume a small plant in a week or two. This is why it’s so important to inspect your plants regularly and act at the very first sign of trouble. Quick intervention is key to a successful recovery.
Your Anubias Awaits Its Comeback
Seeing an anubias plant decaying can be discouraging, but now you are armed with the knowledge to fight back. You understand the critical importance of the rhizome, you have a step-by-step plan for emergency intervention, and you know how to create the perfect environment for it to thrive long-term.
Remember that every challenge in this hobby is a learning opportunity. You’ve just leveled up your plant-keeping skills in a major way. Anubias truly are one of the most rewarding plants in the aquarium world once you understand their one simple rule.
Go save your plant, place it correctly, and watch with pride as it begins its beautiful recovery. Happy scaping!
