Masilea Angustifoilia

Marsilea angustifolia is a species of aquatic fern belonging to the family Marsileaceae. It's commonly known as the narrow-leafed waterclover. This plant is native to various parts of Asia, including India, China, and Japan. It typically grows in shallow water or moist soil, often found along the edges of ponds, streams, and wetlands.

In aquarium hobby, Marsilea angustifolia is a popular choice for planted tanks. Its delicate, narrow leaves and low growth habit make it an attractive foreground or mid-ground plant. It's relatively undemanding in terms of care requirements, thriving in moderate lighting and a nutrient-rich substrate. Proper pruning and maintenance are necessary to prevent it from overgrowing and overshadowing other plants in the aquarium.
