Overview

A compact spear-leaved form of Anubias barteri var. hastifolia, this plant carries glossy dark green foliage tapering to fine points on short stems, staying 3-5 inches. It fills shaded hardscape gaps in low light with no CO2 required and adapts equally well to fully submerged tanks or humid paludariums.

Care

This large-leaved cultivar of Anubias barteri tolerates a wide range of water conditions and low light, making it a dependable choice for beginners and low-tech tanks. It should be fastened to driftwood or rock rather than planted in substrate, since a buried rhizome tends to rot. Growth is slow, so leaves accumulate little damage but also collect algae and debris over time, which benefits from occasional wiping during water changes.

Planting & trimming

Attach the rhizome to driftwood, rock, or other hardscape using cotton thread or fishing line, keeping the rhizome itself above the substrate at all times since burial leads to rot. Plant-safe glue can be used sparingly on roots but should be kept off the rhizome tissue, as some glues can burn and damage it. Trim only older, yellowing, or algae-covered leaves near the base; the plant needs little regular pruning given its slow growth.

Fertilizing

Root tabs offer little benefit since this plant draws nutrients mainly through its leaves and rhizome rather than a substrate root system. A diluted liquid fertilizer containing iron and micronutrients, dosed occasionally, helps maintain deep leaf color and steady growth. Pale or yellowing new leaves can indicate a lack of iron or overall nutrient deficiency in a lean, low-tech setup.

Propagation

New plants are produced by dividing the rhizome with a clean, sharp blade once a section has developed several leaves and some roots. Each division should retain at least two to three leaves to establish well after being reattached to hardscape. Growth is slow, so propagation is infrequent compared to faster-growing stem plants.

Problems

Rhizome rot from burial in substrate or from glue applied directly onto the tissue is the most common cause of loss. Excess light relative to this plant's slow growth rate often results in algae film building up on the tough leaves, particularly diatoms or green spot algae. Otherwise the species is quite resistant to disease and rarely suffers pest issues beyond occasional algae fouling.
