Anubias Barteri

Anubias barteri

plantfreshwater

Anubias barteri is a robust, slow-growing plant with dark-green, waxy leaves that are resistant to herbivorous fish. Like java fern, the rhizome must not be buried. It thrives under low light, though algae can colonise the leaves in high-light environments; shading by taller plants helps.

plant
easy

Anubias Coffeefolia

Anubias barteri var. coffeefolia

plantfreshwater

Anubias Coffeefolia features deeply corrugated, dark-green leaves with a pronounced bullate (puckered) texture that gives them the appearance of coffee leaves — hence the name. The new leaves often emerge with a reddish-bronze tint before darkening to deep green, adding colour interest even at low light levels. Its compact, low-spreading habit suits midground placement in low-tech planted tanks.

plant
easy

Anubias Congensis

Anubias afzelii

plantfreshwater

Anubias Congensis (often sold as Anubias lanceolata) produces elongated, lance-shaped leaves on tall petioles, reaching 30–40 cm in height and making it one of the larger anubias suitable for midground to background use. Its upright, narrow leaf profile creates vertical interest against broader-leafed plants. Like all anubias, the rhizome must remain exposed and anchored to wood or rock.

plant
easy

Anubias Gigantea

Anubias gigantea

Anubias Gigantea is the largest species in the anubias genus, with broad, leathery leaves that can exceed 20 cm in length and reach 60–80 cm in total height in mature specimens. It makes a dramatic focal-point background plant in large aquariums and is equally at home emersed in paludariums. Despite its impressive size it shares the same forgiving, low-maintenance care profile as all anubias.

plant
easy

Anubias Gracilis

Anubias gracilis

plantfreshwater

A distinctive species with arrowhead-shaped, triangular leaves held on long, elegant petioles above the rhizome. The leaf shape sets it apart from other Anubias species and gives the scape a more dynamic, textured look. Grows taller than A. nana but slower than A. barteri. Ideal for attaching to large pieces of driftwood or elevated rock structures.

plant
easy

Anubias Hastifolia

Anubias hastifolia

plantfreshwater

Anubias hastifolia is one of the tallest anubias species, with long, spear-shaped leaves that make a dramatic background plant. Like all anubias it attaches to hardscape and is extremely tolerant of low light and neglect. Slow-growing and long-lived.

plant
easy

Anubias Nana

Anubias barteri var. nana

plantfreshwater

Anubias Nana is the classic dwarf variety of Anubias barteri, producing compact rosettes of small, dark-green ovate leaves on a slow-creeping rhizome. Its diminutive size makes it one of the most popular choices for nano tanks and foreground planting on hardscape. Like all anubias it must be attached to wood or rock — burying the rhizome causes rot.

plant
easy

Anubias Nana Bonsai

Anubias barteri var. nana 'Bonsai'

plantfreshwater

An ultra-compact cultivar of A. nana with smaller leaves and shorter internodal spacing, creating a dense, bushy mound on the rhizome. The 'Bonsai' name refers to its miniaturised, tree-like appearance when grown on a small piece of driftwood or stone. Perfect for nano tanks and desktop aquariums. Care is identical to A. nana — extremely forgiving.

plant
easy

Anubias Nana Petite

Anubias barteri var. nana 'Petite'

plantfreshwater

Anubias Nana Petite is a cultivar even smaller than standard Nana, with leaves rarely exceeding 1.5 cm — making it the go-to foreground and carpeting anubias in nano aquascapes. Its slow growth means algae build-up on leaves is its biggest challenge; moderate flow and controlled nutrients help keep leaves clean. Exceptionally popular in Japanese Nature Aquarium style layouts.

plant
easy

Anubias Nana Round Leaf

Anubias barteri var. nana 'Round Leaf'

plantfreshwater

A cultivar of A. nana with noticeably rounder, broader leaves and very short petioles, giving it a compact, dome-like silhouette.
