Hemianthus has been reclassified and is now known as Micranthemum. Micranthemum is a genus of aquatic plants in the Plantaginaceae family, which includes species such as Micranthemum umbrosum and Micranthemum sp. "Monte Carlo". Like Hemianthus, Micranthemum is known for its small size and ability to form a dense carpet on the substrate, making it a popular choice for aquascaping.
Micranthemum has small, round leaves that are green in color and grow in clusters along thin stems. It requires high lighting and a nutrient-rich substrate to thrive, and it can be propagated by cuttings. Like Hemianthus, Micranthemum can be a challenging plant to grow, but it can create a stunning aquascape if provided with the right conditions.
Overall, Micranthemum is a great addition to any aquascape, providing both aesthetic appeal and functional benefits. It can help to oxygenate the water, absorb excess nutrients, and provide hiding places for fish and other aquatic inhabitants. If you are looking to add a beautiful and unique plant to your aquarium, Micranthemum may be the perfect choice for you.
