Common Names

Anubias heterophylla is commonly known as Congo Anubias.

Origin

Anubias heterophylla is native to various regions of Africa, including Cameroon, Guinea, Angola, and the Democratic Republic of Congo (formerly Zaire). In the wild, they are typically found growing in slow-moving rivers, streams, and along riverbanks where they thrive in both fully and partially submerged conditions. Their adaptability to different aquatic environments makes them a resilient and popular choice for aquariums.

Lighting Requirements

Anubias heterophylla can adapt to a wide range of lighting conditions, from low to medium light levels. They are naturally slow-growing and prefer subdued lighting, making them ideal for low-tech setups or tanks with limited lighting. While they can tolerate aquarium lighting, avoid placing them under intense, bright lights, as this may encourage algae growth on their leaves. If grown partially submerged, it is important to mist the exposed leaves daily to prevent them from drying out under the lights. Proper placement in shaded areas or beneath taller plants can help regulate their light exposure.

Propagation

Propagation of Anubias heterophylla is easily achieved through rhizome division. The rhizome should always remain above the substrate, as burying it too deeply can cause it to rot. When dividing the rhizome, ensure that each new portion has at least 3 leaves and a healthy section of the rhizome to support new growth. Avoid cutting very small sections, as this can weaken the plant.

Left to its own devices, the rhizome will naturally spread along the substrate, sending out new shoots to form additional plants. To promote healthy growth, provide plenty of space around the plant and avoid overcrowding with other plants. You can also attach the rhizome to driftwood or rocks using fishing line or plant glue, allowing it to anchor itself over time. This method not only prevents the risk of rhizome rot but also creates an attractive aquascape.

Difficulty

Anubias heterophylla is a hardy and undemanding plant, making it perfect for beginners. It can tolerate a wide range of water conditions, including varying pH levels, temperatures, and water hardness. Once established, the plant requires minimal maintenance and rarely needs pruning, as it grows slowly. In tall aquariums, it may produce longer stems as it strives to reach the water surface, adding a vertical element to the tank's design. Overall, this species is highly adaptable and thrives in both high-tech and low-tech aquarium setups.

Short Description

Anubias heterophylla is one of the tallest species in the Anubias genus, known for its sturdy, lance-shaped leaves. While it grows taller when partially submerged, it can still reach impressive heights when fully submerged in the aquarium. Although the plant may occasionally produce underwater flowers, this is rare. It is sometimes propagated using seeds, though rhizome division is the more common method in aquariums.

One unique feature of Anubias heterophylla is its slow growth rate, which makes it a fantastic addition to aquariums without overwhelming other plants or taking up too much space. However, because of this slow growth, algae may develop on the older leaves over time. This is perfectly normal and can even enhance the plant's natural beauty, but occasional cleaning of the leaves may be necessary to maintain their appearance.

This plant looks stunning when attached to rocks or driftwood, where it will gradually secure itself. To achieve this, you can use fishing line to tie the rhizome to the hardscape until it anchors naturally. Be sure to remove all fishing line once the plant has attached itself, to prevent any harm to fish or other tank inhabitants. Overall, Anubias heterophylla is an excellent choice for aquascapers seeking a low-maintenance, visually appealing plant that adds height and depth to their aquariums.
