It has both aquatic and terrestrial forms and is a popular plant in aquariums, the dense mats considered good habitat for fish to lay their eggs. It has also been found to absorb heavy metals and may prove beneficial in wetland remediation efforts as well as a process known as phytomining, where these metals are harvested from plants.” Known for forming dense clumps of carpet-like hair-like foliage only 4-6” tall. Great for fish spawning. Can be grown above water, or completely underwater in an aquarium or pond.
