What is Anubias Nana Rhizome Rot, and Why Does It Happen?
Before we dive into the fix, it’s important to understand what we’re up against. Think of the rhizome as the plant’s main artery—a thick, horizontal stem from which both roots and leaves grow. It’s the life force of your Anubias.
Rhizome rot is a bacterial infection that causes this vital part of the plant to decay, turning it soft, brown, and foul-smelling. When the rhizome rots, it can no longer transport nutrients, and the entire plant begins to die.
But what causes it? It almost always boils down to one primary mistake.
The Number One Cause: Burying the Rhizome
If you take away only one thing from this article, let it be this: Do not bury the Anubias rhizome in your substrate!
This is, by far, the most common reason for rot. The rhizome needs to be exposed to open, flowing water to “breathe.” When it’s buried in sand or gravel, it gets smothered. The lack of oxygen creates an anaerobic environment—perfect for the nasty bacteria that cause rot to thrive.
Instead of planting it like a traditional stem plant, you should always attach your Anubias to a piece of driftwood or a rock. You can use super glue gel (aquarium-safe cyanoacrylate) or a piece of cotton thread to secure it. The roots will eventually anchor themselves to the surface.
Other Contributing Factors
While burying the rhizome is the main culprit, a few other things can contribute to the problem:
- Poor Water Flow: Stagnant water around the plant can also create low-oxygen zones, inviting rot.
- Physical Damage: A bruised or broken rhizome is an open wound, making it vulnerable to bacterial infection. This often happens during shipping or rough handling.
- Overall Poor Tank Health: A dirty tank with high organic waste can harbor higher levels of harmful bacteria, increasing the risk of infection.
Spotting the Early Warning Signs: A Visual Guide
Catching rhizome rot early is key to saving your plant. The sooner you act, the higher the chance of a full recovery. Here’s what to look for during your regular tank checks.
Look for these red flags:
- Yellowing Leaves: Often, the first sign is one or two leaves suddenly turning yellow, starting from the base where they connect to the rhizome.
- Mushy or Soft Spots: Gently touch the rhizome. A healthy one is firm and solid, like a crisp carrot. If you feel any soft, squishy, or mushy sections, you have a problem.
- Dark Discoloration: The rhizome should be a healthy green or light brown. Look for dark brown or black patches, as this is a clear sign of decay.
- A Foul Odor: If the rot is advanced, you might notice a distinct “rotting vegetation” smell when you handle the plant.
- Leaves Falling Off Easily: If leaves detach from the rhizome with a gentle tug, the connection point has likely started to rot.
Don’t just glance at your Anubias; make a habit of giving the rhizome a gentle poke every now and then. It’s the best way to catch one of the most common problems with anubias nana rhizome rot before it’s too late.
The Ultimate Anubias Nana Rhizome Rot Rescue Mission: A Step-by-Step Guide
Okay, you’ve confirmed you have rot. Don’t panic! It’s time to play plant surgeon. This process can save the healthy parts of your plant and give it a fresh start. Follow this how to anubias nana rhizome rot treatment plan carefully.
Step 1: Gather Your Tools
Before you remove the plant, get your operating station ready. You’ll need:
- A sharp, clean razor blade or pair of scissors.
- A container with some of your aquarium water.
- Optional: Aquarium-safe super glue gel (cyanoacrylate).
- Optional: A small, soft brush (like a new toothbrush).
Step 2: Remove and Assess the Plant
Carefully take the Anubias out of your tank and place it in the container of tank water. Gently rinse off any debris and get a good look at the rhizome. Identify all the soft, mushy, and dark-colored areas. You need to be ruthless here—any infected tissue left behind can cause the rot to return.
Step 3: Perform Plant Surgery
This is the most critical step. Using your clean razor blade, you need to cut away every single bit of the rotted rhizome.
Make your first cut in a healthy, firm green section, well away from the infected area. You want to see clean, healthy tissue inside. If the inside of the rhizome is still brown or discolored where you cut, you need to cut further back.
Keep cutting until you are left with only solid, green, healthy rhizome sections.
It can be tough, but you must remove all the rot. It’s better to be left with a small, healthy piece of rhizome than a large piece that is still harboring the infection. You may end up with several small, healthy fragments. That’s perfectly fine! Each one can grow into a new plant.
Step 4: The Optional “Disinfectant” Dip
Some aquarists have success with a quick dip in 3% hydrogen peroxide to help kill any lingering bacteria on the freshly cut surfaces. If you choose to do this, be extremely cautious.
Dip only the cut end of the rhizome into the peroxide for about 15-30 seconds. You should see it fizz. Immediately rinse it thoroughly in clean, dechlorinated water before putting it back in the aquarium. Do not let the leaves touch the peroxide.
Step 5: Replant with Care
Now it’s time to re-home your saved Anubias pieces. Remember the golden rule: keep the rhizome above the substrate.
Use a small dab of super glue gel to attach the healthy rhizome piece to a rock or piece of driftwood. Hold it in place for about 30-60 seconds until it sets. You can then place it back in your aquarium, preferably in an area with gentle but consistent water flow.
Prevention is the Best Medicine: Anubias Nana Rhizome Rot Best Practices
You’ve saved your plant—congratulations! Now let’s make sure this never happens again. Following this simple anubias nana rhizome rot care guide will keep your plants happy and healthy.
Proper Planting Technique
We’ve said it before, but it’s the most important of all anubias nana rhizome rot tips. Attach your Anubias to hardscape like rocks or wood. Let the roots hang down into the water column or find their own way into the substrate. The rhizome must stay exposed.
Ensure Good Water Flow
Position your Anubias where it will receive gentle, consistent flow from your filter outlet or a powerhead. This prevents dead spots and ensures the rhizome gets plenty of oxygen, which is a core tenet of sustainable aquarium keeping. This simple, eco-friendly anubias nana rhizome rot prevention method works wonders.
Acclimate New Plants Carefully
When you get a new Anubias, inspect it thoroughly for any soft spots or damage before adding it to your tank. Many plants are damaged in transit. If you find any mushy bits, it’s best to perform the surgery described above as a preventative measure before you even plant it.
Maintain a Clean Tank
Regular water changes and gravel vacuuming reduce the overall amount of organic waste and harmful bacteria in your aquarium. A healthier environment means a lower risk of all types of infections for your fish and plants.
Common Mistakes That Lead to Rhizome Rot (And How to Avoid Them)
We all make mistakes in this hobby. Learning from them is how we grow! Here are a few common pitfalls that can lead to disaster for your Anubias.
- Mistake 1: Jamming it between rocks. While this seems like a good way to anchor it, tightly wedging the rhizome can bruise it and restrict water flow, leading to rot.
- Mistake 2: Tying it too tightly. Using fishing line or thread is fine, but if you tie it so tightly that it cuts into the rhizome, you’re creating an open wound for bacteria.
- Mistake 3: Ignoring the signs. A single yellow leaf might not seem like a big deal, but it can be the first cry for help. Be proactive and investigate the cause right away.
The “benefits of anubias nana rhizome rot” are non-existent, but the benefit of *preventing* it is a lush, green, and thriving plant that adds incredible beauty to your aquascape for years on end.
Frequently Asked Questions About Anubias Nana Rhizome Rot
Can Anubias recover from rhizome rot?
Yes, absolutely! As long as there is some firm, healthy green rhizome left, the plant can be saved. You just need to be diligent about cutting away all the infected tissue and replanting it correctly.
How fast does rhizome rot spread?
It can spread quite quickly, sometimes destroying a whole plant in a week or two if left unchecked. This is why early detection and immediate action are so important.
Does cutting the rhizome harm the Anubias?
Not at all! In fact, cutting the rhizome is how you propagate (create new) Anubias plants. As long as you use a clean blade and the piece you are saving has a few leaves and roots, it will grow into a new, healthy plant.
Can I just leave the rhizome on top of the gravel?
You can, but it’s not ideal. The plant isn’t anchored and can get knocked around easily by fish or water currents. Attaching it to a small rock or piece of wood is a much more stable and secure method.
Your Anubias Can Thrive Again!
Dealing with anubias nana rhizome rot can feel discouraging, but it’s a valuable learning experience for any aquarist. By understanding the cause, learning how to perform a rescue, and following a few simple best practices, you can turn this problem into a success story.
Remember the golden rule—never bury the rhizome—and you’ve already won half the battle. Your Anubias is a tough, resilient plant. Give it the right conditions, and it will reward you with slow, steady growth and beautiful green leaves that bring your underwater world to life.
So go ahead, check on your plants with confidence. You now have the knowledge to keep them healthy and thriving. Happy scaping!
