Umbrella Hairgrass (Eleocharis vivipara)
Remarks: Umbrella hairgrass (Eleocharis vivipara) is a unique and lush plant native to the southeastern United States. It is commonly found growing along the edges of shallow ponds, ditches, streams, floodplains, and marshes in the wild. It serves as shelter for fish fry, small crustaceans, and other small aquatic animals.
In the aquarium, umbrella hairgrass is ideal for filling background space. It grows in tall, wispy strands that bend over to form a natural canopy when reaching the water surface. Typically, it grows to 12–16 inches tall in an aquarium, though it can reach up to 20 inches or more under optimal conditions.

I planted umbrella hairgrass in my 20-gallon tank and it has grown steadily over the past three months. The tall, wispy strands create a natural canopy that adds depth and beauty to the background. My small fish use it for shelter, and it looks very natural in the water.
