List of freshwater aquarium plant species

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.

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.

Many of these species are dangerous invasives and should be disposed of in a way that guarantees that they will not enter local waters.

Few algae, such as marimo (Aegagropila linnaei), are sought after and intentionally cultivated in freshwater aquaria.
