Troubleshooting Anubias Care: A Practical Playbook

Looking for answers to your Anubias woes? You’re not alone—these hardy aquarium favorites sometimes present puzzling problems in even well-maintained aquascapes. Whether you’re facing yellow leaves, unhealthy roots, melting, or persistent algae, this practical playbook covers all you need to know about troubleshooting and reviving your Anubias.
Let’s dig in and give your plants the love they deserve!

Common Anubias Problems and Their Causes

Anubias species, such as Anubias barteri, Anubias nana, and Anubias hastifolia, are among the most popular aquarium plants for beginners and seasoned aquascapers alike. While they’re considered low-maintenance, problems can still arise, particularly in low-tech freshwater tanks.

1. Yellowing Leaves

• Symptoms: Yellow, translucent, or spotted leaves.
• Causes: Nutrient deficiencies (particularly potassium, iron, or nitrogen), poor water circulation, or inadequate lighting.

2. Melting or Rotting Leaves

• Symptoms: Rapid disintegration, mushy leaves, or exposed veins.
• Causes: Plant stress after planting, rhizome burial in substrate, sudden parameter shifts, or root rot from poor water quality.

3. Algae on Leaves

• Symptoms: Black beard algae, green spot algae, or fuzzy coatings on leaf surfaces.
• Causes: Direct light exposure, stagnant water, and excessive organic waste.

4. Stunted Growth

• Symptoms: Lack of new leaves, small or misshapen growth, long periods without noticeable development.
• Causes: Insufficient nutrients, infrequent water changes, and overly dense planting blocking light.

How to Diagnose Anubias Issues

Before you can fix it, you need to find the root of the problem! Here’s how to reliably diagnose common Anubias care issues:

• Check parameters: Test for ammonia, nitrite, nitrate, KH, GH, and pH.
• Observe plant positioning: Is the rhizome above substrate? Is the plant in direct light?
• Assess tank mates: Are there herbivorous fish or snails nibbling the leaves?
• Review fertilizer routine: Are you dosing root tabs or liquid fertilizers? Is there sufficient flow?

Step-by-Step Solutions for Healthy Anubias

1. Fixing Yellow Leaves

1. Test water for nutrient deficiencies, especially iron and potassium.
2. Supplement with a comprehensive liquid fertilizer designed for aquarium plants. For more on dosing, see our Beginner’s Guide to Aquascape Fertilizers.
3. Trim affected leaves near the rhizome to promote new growth.
4. Monitor indirect light exposure (avoid strong, direct overhead light).

2. Preventing and Treating Leaf Melt

1. Never bury the rhizome: Attach Anubias to rocks or driftwood with thread or aquarium-safe glue.
2. Allow time to acclimate, especially if the plant was grown emersed.
3. Maintain stable water parameters—avoid rapid temperature or pH swings.
4. Improve circulation to discourage stagnant zones near roots.

3. Combating Algae on Anubias

1. Reduce light exposure—Anubias do best in shaded areas of your aquascape.
2. Increase water changes to reduce organic waste.
3. Add algae-eating tank mates like Amano shrimp or Nerite snails.
4. Gently remove algae using a soft toothbrush; avoid harsh chemicals.

4. Encouraging Robust Anubias Growth

1. Ensure regular dosing with all-in-one liquid plant fertilizers.
2. Trim old or damaged leaves to stimulate new shoots.
3. Spread Anubias plants for better light and nutrient access, particularly in complex aquascape layouts.
4. Perform consistent, gentle tank maintenance—including frequent, small water changes.

Top Tips for Long-Term Anubias Health

• Keep Anubias attached to hardscape—never bury the rhizome!
• Use low to moderate lighting and incorporate shaded spots within your aquarium layout.
• Monitor water quality regularly; moderate flow prevents detritus buildup on leaves.
• Be patient! Anubias are notoriously slow growers, so don’t expect rapid changes.

FAQs: Anubias Troubleshooting in Aquascaping

Why are my Anubias leaves turning brown or black?

This is often due to algae accumulation, old age, or nutrient imbalances. Remove the affected leaves and adjust lighting or nutrient dosing as needed.

Can Anubias grow fully submerged?

Yes! Anubias thrives in both emersed and submerged conditions, making it one of the most adaptable low-light aquarium plants.

What’s the ideal temperature and pH for Anubias?

Keep water temperatures between 22-28°C (72-82°F) and stable pH from 6.0 to 7.5 for optimal growth.

How can I prevent snail or fish damage?

Choose peaceful tankmates and supplement plant food if you keep herbivores. Remove damaged leaves promptly.
