Hemianthus callitrichoides ‘Cuba’ aquarium plant – 5 cm pot

Hemianthus callitrichoides is one of the smallest aquarium plants in the world, and creeps over the bottom with millimetre-sized, round leaves. Hemianthus callitrichoides is an attractive and popular foreground plant for small aquariums.
It is not a difficult plant, but it requires good conditions such as enough light, added CO2, water circulation and fertilizer to thrive. If these conditions are hard to create, you may use Micranthemum ‘Monte-Carlo’ as an alternative, as it is less demanding.
Small pearls or bubbles of oxygen are often produced on top of the plants, adding a very lively aspect to the carpet.
If planted in small clumps a few centimetres apart, it will spread rapidly and cover the bottom like a carpet. Trim the carpet regularly, otherwise the lower parts will not get enough light causing root death.
Found on Cuba, west of Havana

Create a lush, vibrant green carpet with Hemianthus callitrichoides ‘Cuba’, commonly known as HC Cuba. This popular carpeting plant produces tiny, rounded leaves and a dense, low-growing habit. Consequently, it is a favourite among aquascapers looking to create natural lawns, miniature landscapes and detailed underwater scenes.

Native to Cuba, this delicate aquatic plant grows along the substrate and gradually spreads through creeping stems. With the right conditions, it forms a compact carpet that softens the appearance of aquarium gravel and creates a beautiful foreground. Moreover, its small leaves provide an excellent sense of scale in nano aquariums and carefully designed aquascapes.

Hemianthus callitrichoides ‘Cuba’ generally performs best with good lighting and a nutrient-rich substrate. Additionally, CO₂ supplementation encourages more compact growth and helps the plant spread more reliably. Although it can be grown without injected CO₂, achieving a dense, healthy carpet is usually more challenging. Consistent fertilisation and suitable water circulation can also support its development.

For the best results, plant small portions with space between them. This approach allows the creeping stems to spread and gradually fill the gaps. Furthermore, regular trimming can help maintain a neat carpet and encourage denser growth as the plant establishes.

HC Cuba is particularly well suited to the foreground of planted freshwater aquariums. It pairs beautifully with decorative stones, driftwood and contrasting aquatic plants. However, its small size and demanding growth requirements mean it is generally better suited to aquarists prepared to maintain stable conditions.

Transform the foreground of your aquarium with the delicate leaves and vibrant green finish of Hemianthus callitrichoides ‘Cuba’. Add this classic carpeting plant to your aquascape today!
