Hemianthus callitrichoides (HC) 'Cuba' is one of the smallest ground creepers available in the hobby. It is popular as a carpet as its small size makes for a very fine carpet and contrasts well with even other small leaved plants. HC Cuba is notorious for being one of the harder carpeting plants to grow well in the planted aquarium. It is often called dwarf baby tears in the hobby, but this can easily lead to mix-ups as "baby tears" can refer to a couple of other plants as well.
