Anubias barteri 'Mini Coin'

Anubias barteri ‘Mini Coin’ is a compact and visually distinctive aquatic plant that has gained popularity among aquascaping enthusiasts for its small, round leaves and slow, manageable growth. This plant is a miniature variant of the well-known Anubias barteri family and is particularly valued for its decorative appearance and adaptability in planted aquariums. With its coin-shaped foliage and rich green color, it adds subtle texture and natural beauty to aquascapes of all styles.

Native to the freshwater rivers and streams of West Africa, Anubias species typically grow attached to rocks, roots, and submerged wood along shaded riverbanks. Anubias barteri ‘Mini Coin’ shares these natural characteristics, developing from a horizontal rhizome rather than traditional roots buried in substrate. This growth structure makes it ideal for attaching to driftwood, stones, or other hardscape materials commonly used in aquascaping.

The defining feature of this plant is its tiny circular leaves. Each leaf resembles a small green coin, giving the plant its name and unique visual appeal. The leaves are thick, slightly glossy, and durable, allowing them to withstand a wide range of aquarium conditions. When grown in clusters, these rounded leaves create a lush, ornamental look that contrasts beautifully with finer plants such as mosses or stem species.

Because of its miniature size, Anubias barteri ‘Mini Coin’ is particularly well suited for nano aquariums and detailed aquascapes. It can be used in the foreground or midground, where its compact growth creates small bush-like formations. Aquascapers frequently attach this plant to small pieces of driftwood or stones to create natural-looking compositions that mimic plants growing on submerged roots in nature.

One of the biggest advantages of this plant is its hardiness. Anubias barteri ‘Mini Coin’ can thrive in low to moderate lighting conditions, making it suitable for both low-tech aquariums and more advanced planted tanks. While stronger lighting can encourage slightly faster growth, the plant maintains its shape and coloration even under relatively modest light levels.

CO₂ injection is not required for this species, although it can promote healthier growth and slightly larger leaves when provided. Because the plant grows slowly, it is also less demanding in terms of nutrients compared to many fast-growing stem plants. Regular dosing of liquid fertilizers containing micronutrients such as potassium and iron will help maintain vibrant foliage and overall plant health.

Unlike rooted plants that absorb nutrients primarily through the substrate, Anubias species absorb most of their nutrients directly from the water column. For this reason, they perform well even in aquariums with inert substrates like sand or gravel, as long as the water is properly fertilized.

Propagation is simple and occurs through rhizome division. When the plant becomes larger, the rhizome can be carefully cut into sections, ensuring each piece has a few healthy leaves and roots. These sections can then be attached to new surfaces in the aquarium, gradually expanding the plant across the aquascape.

It is important to avoid burying the rhizome in substrate, as this can lead to rot. Instead, the rhizome should remain exposed and secured to hardscape using aquarium-safe glue, thread, or fishing line until the plant naturally anchors itself.

In aquascaping design, Anubias barteri ‘Mini Coin’ is often used to create fine details and natural textures within the layout. Its rounded leaves soften the appearance of rocks and driftwood while adding depth to planted compositions. It pairs particularly well with mosses, Bucephalandra species, and other epiphytic plants commonly used in nature-style aquascapes.

Another benefit of this plant is its compatibility with aquarium animals. The thick leaves are generally resistant to grazing by shrimp and most herbivorous fish, making it a reliable choice for community aquariums.

Because of its small size, slow growth, and elegant leaf shape, Anubias barteri ‘Mini Coin’ is an excellent plant for aquarists who want to add subtle detail and structure to their aquascapes without introducing high-maintenance species. Whether used in a nano aquarium or as part of a larger aquascaping layout, this plant brings a natural and refined aesthetic to planted tanks.
