Facts on Freshwater Plants


Freshwater plants are categorized as floating; submerged, which means all of the plant grows under water; or marginal, where only the roots grow under the water line. Plants native to monsoonal areas are often terrestrial during the dry season and aquatic during the wet season, but most are adaptable to year-round aquatic growth.


Plants use light, nutrients in the water and carbon dioxide to produce oxygen. When the plant releases the oxygen it dissolves directly into the water making it available for fish and beneficial bacteria.

Water Clarity

Plants are very efficient at removing toxins and other nutrients from the water that might be harmful to fish and animals. They help reduce algae and bacterial blooms from clouding the water.


Plants provide much needed shade for fish and other aquatic life. They prevent still spots in the water from overheating in the mid day sun and help regulating the overall temperature of the body of water.


Many freshwater plants provide food for aquatic life by dropping fruit and seeds into the water. Herbivorous fish like to dine on tender underwater shoots that are usually highly nutritious.


Plants add a natural aspect to a garden pond and help blend it into the surrounding landscape. The addition of a few aquatic plants to an aquarium can transform a plain fish tank into an aquatic jungle.
