The Science Behind Anubias Care
When it comes to aquascaping, few plants are as revered and beginner-friendly as Anubias. Known for its robust nature and captivating, deep green leaves, Anubias has become a staple in planted aquariums worldwide. But have you ever wondered about the science behind successful Anubias care? In this article, we’ll dive deep into what makes Anubias thrive, sharing practical, science-backed tips for healthy growth and enduring beauty in your aquascape.
Understanding Anubias: The Basics
Anubias is a genus of aquatic and semi-aquatic plants commonly found in slow-moving rivers and streams across Africa. Their sturdy, leathery leaves and adaptable growth habits make them top choices for beginner and expert aquascapers alike. Popular species like Anubias barteri, Anubias nana, and Anubias coffeefolia repeatedly prove their resilience in both low-tech and high-tech aquarium setups.
Unique Adaptations
- Rhizome growth: Unlike many aquatic plants, Anubias grows from a thick rhizome that must remain exposed, rather than buried in substrate.
- Low-light tolerance: These plants are shade-lovers, naturally growing beneath dense canopy cover.
- Slow growth rate: Anubias develops new leaves slowly, allowing you to maintain a stable aquascape layout.
The Science of Anubias Lighting
One of the biggest myths in aquarium plant care is that all plants need high light. Anubias, however, is uniquely adapted to thrive in low-light environments. In their natural habitat, Anubias receives only dappled sunlight. Reproducing this environment in your aquarium is key to healthy, algae-free leaves.
Light Levels for Anubias
- Low to moderate light (15-35 PAR): Ideal for most species of Anubias.
- Photoperiod: Limit lighting to 6-8 hours per day to prevent algae growth, as slow-growing leaves attract unwanted algae if exposed to intense, prolonged light.
Pro Tip:
Position your Anubias under hardscape features like driftwood or rocks in your aquascape to mimic their natural shade and prevent excessive algae.
Water Parameters and Nutrients
Anubias is renowned for its adaptability, tolerating a wide range of water conditions. However, understanding the ideal parameters can help you unlock its full potential.
| Parameter | Ideal Range |
|---|---|
| Temperature | 72-82°F (22-28°C) |
| pH | 6.0-7.5 |
| GH/KH | 3-8 dGH/3-8 dKH |
| CO2 | Not required, but can improve growth |
Essential Nutrients
Despite their hardiness, Anubias still need nutrients to thrive. Since they absorb most nutrients through the water column rather than the substrate, dosing a quality all-in-one liquid fertilizer can make a noticeable difference in leaf color and overall health. Iron, potassium, and micronutrients are especially valuable.

Preventing Common Anubias Problems
Algae on Leaves
Due to their slow growth, Anubias leaves are prone to green spot and beard algae. The best defenses are:
- Controlling light exposure
- Good water circulation
- Regular aquarium maintenance (removing detritus, scheduling water changes)
- Algae-eating tank mates like Amano shrimp or Otocinclus catfish
Rhizome Rot
Never bury the rhizome beneath the substrate. This deprives it of oxygen and encourages rot. Instead, attach Anubias to hardscape materials using fishing line, thread, or aquarium-safe glue until it takes root.
Propagating Anubias: Science Meets Art
One of the joys of aquascaping with Anubias is easy propagation using the rhizome. Simply cut the healthy rhizome into sections, ensuring each piece has at least 3-4 leaves. Reattach these sections to new locations in your aquarium or share with fellow hobbyists.
Step-by-Step Propagation
- Use sterilized scissors to cut the rhizome.
- Inspect each section for healthy roots and leaves.
- Secure the cuttings to driftwood, lava rock, or other décor.
- Monitor for new growth; leaves and roots should develop over several weeks.

Frequently Asked Questions
Can Anubias grow fully submerged?
Yes. While Anubias can survive emersed or submerged, it truly thrives in fully aquascaped aquariums.
Is CO2 injection necessary?
CO2 is not required, but supplemental CO2 will encourage slightly faster growth and richer leaf color.
How often should I fertilize?
A weekly liquid fertilizer dosing routine is usually sufficient for healthy, vibrant Anubias.
