Species Overview
Pearl Weed (Hemianthus micranthemoides) is a versatile, bright green stem plant that can be shaped into a dense foreground carpet or left to grow into a bushy midground accent. Unlike some demanding carpet plants, it is relatively forgiving and can adapt to various aquarium conditions.
Care & Placement Guidelines
To encourage carpeting, provide moderate to high lighting and trim the stems aggressively, replanting the tops. While it can grow without supplemental CO2, adding it will significantly increase density and horizontal growth. Its growth habit changes with lighting: under strong light, it tends to creep along the substrate, while lower light encourages vertical growth. Regular trimming is necessary to maintain its shape and prevent the lower portions from being shaded out.
