Anubias Care Guide

Anubias Care Guide

Anubias are hardy aquatic and semi-aquatic plants popular in freshwater aquariums and terrariums. Known for their thick, dark green leaves and slow growth, they're one of the most beginner-friendly aquatic plants available.

Light

Anubias prefer low to medium light. They are one of the few aquatic plants that thrive in low-light tanks. Avoid intense direct light, which promotes algae growth on their slow-growing leaves.

Water & Placement

Anubias can be fully submerged or grown emersed (with leaves above water). They should never be planted with their rhizome buried in substrate — attach them to driftwood, rocks, or decorations using fishing line or aquarium-safe glue. Burying the rhizome causes rot.

Water Parameters

Anubias are adaptable to a wide range of water conditions. They prefer temperatures between 72–82°F (22–28°C), pH 6.0–7.5, and soft to moderately hard water.

Fertilizing

Anubias are slow growers and have modest nutrient needs. Liquid fertilizers and CO2 supplementation can encourage growth but are not required. Root tabs near the rhizome can also help.

Maintenance

Trim old or algae-covered leaves at the base to keep the plant tidy. Wipe leaves gently with a soft cloth if algae accumulates. Reduce light duration if algae is a persistent problem.

Common Issues

• Rhizome rot: Caused by burying the rhizome — always attach to hardscape.
• Algae on leaves: Reduce light intensity or duration; add algae-eating fish or snails.
• Yellowing leaves: Nutrient deficiency — add liquid fertilizer.

Propagation

Propagate by dividing the rhizome. Cut with clean scissors, ensuring each section has at least a few leaves and roots. Attach both sections to hardscape.
