Rotala rotundifolia is a time-tested popular stem plant wonderfully suitable for aquascaping. Its emerged form has roundish leaves, in the aquarium they grow to a longer, narrow form. Compared with other Rotala species it is relatively undemanding. This highly variable species is widely distributed in the Asian subtropics and tropics; standard variants available in trade are light green to reddish under water, depending on the light intensity.
Just like fish, living plants do best when they are kept in an aquarium that best suits their needs. Selecting live plants that share common water conditions will minimize problems and make it easier for you to maintain and keep your aquarium in tip top shape.
