Propagating Anubias 'Nangi': Rhizome Division for a Hardy Hybrid

A practical guide to propagating the hardy Anubias 'Nangi' hybrid by rhizome division, mounting divisions on wood or rock for slow, dense epiphytic growth.

Overview

Anubias 'Nangi' is a hardy aquarium hybrid of the genus Anubias, an aroid (family Araceae) native to tropical central and western Africa, where the plants grow in rivers, streams and marshes. It is prized for elongated, pointy leaves and thick, strong foliage, growing horizontally along its rhizome while sending leaves upward.

Like all Anubias it is a slow grower that tolerates a wide range of water parameters, prefers subdued light and needs no CO2. It is grown as an epiphyte on wood or rock, and is propagated by dividing the rhizome rather than by cuttings.

Propagation Method (Rhizome Division)

Anubias reproduces through rhizome (stolon) division or by separating side shoots. A longer rhizome is cut into smaller pieces with a blade or scissors, and each piece grows into a new plant. Each division must retain several leaves so it can sustain itself while re-establishing.

Step-by-Step

Choose a well-established 'Nangi' whose rhizome has lengthened and carries several leaves.
With a sharp, clean blade, cut the rhizome into segments, each with 3-4 leaves and roots; make a single clean cut.
Mount each division on driftwood or rock using cotton thread or super-glue gel, leaving the rhizome fully exposed.
Place the mount under subdued light in clean, stable water; new leaves typically appear after several weeks.

Conditions for Healthy Growth

Lighting: low to subdued; shaded placement helps keep leaves algae-free.
Temperature: roughly 22-28 C.
CO2: not required; 'Nangi' is undemanding and acclimates to varied parameters.
Placement: epiphytic on wood or rock; its dense growth suits the midground.

Maintenance

Maintain clean, filtered water with low organic waste to keep this slow grower algae-free, and keep the rhizome exposed. Expect a long acclimation: a newly mounted division may take several weeks before sprouting new leaves. Trim old or damaged leaves at the base.

Common Challenges

Slow leaf turnover means algae can settle on older leaves; reduce light intensity and keep waste low. Patience is essential, as 'Nangi' takes weeks to settle into a new tank.
