From Wikipedia, the free encyclopedia
Aquatic plants are used to give the freshwater aquarium a natural appearance, oxygenate the water, absorb ammonia, and provide habitat for fish, especially fry (babies) and for invertebrates. Some aquarium fish and invertebrates also eat live plants. Hobbyists use aquatic plants for aquascaping, of several aesthetic styles.

Most of these plant species are found either partially or fully submerged in their natural habitat. Although there are a handful of obligate aquatic plants that must be grown entirely underwater, most can grow fully emersed if the soil is moist. Though some are just living at the water margins, still, they can live in the completely submerged habitat.
The taxonomy of most plant genera is not final. Scientific names listed here may, therefore, contradict other sources. Many of these species are dangerous invasives and should be disposed of in a way that guarantees that they will not enter local waters.
Common aquarium plant species:
Most algae in hobby aquaria are unwanted, nuisance plants. Few algae, such as marimo (Aegagropila linnaei), are sought after and intentionally cultivated in freshwater aquaria.
Several species of terrestrial plants are frequently sold as "aquarium plants". While such plants are beautiful and can survive and even flourish for months under water, they will eventually die and must be removed so their decay does not contaminate the aquarium water. These plants have no necessary biology to live underwater.
