Dwarf hairgrass (lat. Eleocharis parvula) is one of the best aquarium plants, if you need to create a ‘real lawn’ in a tank. This is a representative of coastal-aquatic vegetation, which natural habitat spreads all over the world and this fact consequently shows that the plant is easy to keep. Due to its ability to cover the substrate surface with thick green carpet, dwarf hairgrass is more often used in the foreground of a tank, which helps to imitate thick green lawns or grassplots.
