Anubias barteri var. nana ‘Dark Moon’ Care Guide

Common Name: Anubias Dark Moon
Difficulty Level: Easy

General Description:

Anubias barteri var. nana ‘Dark Moon’ is a rare and visually striking Anubias variety characterized by its thick, deep green to almost black leaves and compact growth habit. Its slow growth and exceptional durability make it ideal for low-tech aquariums, nano tanks, and aquascapes that emphasize contrast and texture. The dark foliage pairs beautifully with lighter plants and hardscape, creating a bold and elegant focal point.

Care Requirements:

1. Tank Size:

Minimum Tank Size: 5 gallons (20 liters)

2. Lighting Requirements:

Lighting: Low to Moderate

Low light maintains the dark coloration and minimizes algae growth. Excessive light may cause algae to form on the leaves.

3. CO₂ Requirements:

CO₂: Not required

CO₂ supplementation is optional and may slightly increase growth rate but is not necessary for healthy development.

4. Water Parameters:

Temperature: 22–28°C (72–82°F)
pH: 6.0–7.5
Hardness: Soft to moderately hard

5. Substrate:

Substrate Type: Not required

The rhizome must remain above the substrate. Best attached to rocks, driftwood, or décor.

6. Fertilization:

Nutrients: Low

Light liquid fertilization supports healthy leaves. Excess nutrients combined with strong light can promote algae.

7. Maintenance:

Growth Rate: Slow

Very low maintenance. Remove algae manually if needed and trim damaged leaves occasionally.

8. Propagation:

Propagation Method: Rhizome division

Cut the rhizome into sections, ensuring each portion has several healthy leaves.

9. Placement in Tank:

Placement: Foreground to Midground

Ideal for accenting hardscape and creating strong visual contrast in planted aquariums.

Summary:

Anubias barteri var. nana ‘Dark Moon’ is a premium ornamental plant valued for its dark foliage, resilience, and compact size. It thrives in low-light environments, requires minimal maintenance, and adds depth and sophistication to aquascapes. A perfect choice for both beginners and advanced aquascapers.
