Anubias barteri is a robust, slow-growing aquatic plant from the Araceae family, native to tropical West and Central Africa where it grows along riverbanks, stream margins, and shaded forest floors in humid, warm conditions. In the aquarium it is classified as an epiphyte — it does not require substrate planting and grows best when its rhizome is tied or glued to driftwood, rocks, or decorations, with its roots spreading freely into the water column to anchor the plant and absorb nutrients. The broad, ovate, dark green leaves are thick, leathery, and extremely tough, resisting damage from herbivorous fish, aggressive water flow, and rough handling far better than most aquatic plants. The distinctive horizontal rhizome should never be buried in substrate, as this causes rot and kills the plant. Anubias barteri is one of the most light-tolerant aquatic plants in the hobby — it actively prefers low to moderate light and will suffer algae growth on its slow-growing leaves under intense illumination. In fact, one of its most common challenges is managing green spot algae or brush algae on the older leaves, which accumulate over time due to the plant's slow leaf turnover. Under good conditions it produces white, arum-style flowers both submerged and emersed, which are prized as decorative features. CO2 supplementation is not required, though it slightly accelerates the naturally slow growth rate. Anubias barteri serves as a natural backdrop plant, midground feature, or attachment to driftwood in virtually any freshwater tropical aquarium setup.
