Rotala rotundifolia is a versatile and popular aquarium plant known for its vibrant colours and adaptability, making it a favourite choice among aquascapers. Originating from Southeast Asia, this plant is characterized by its slender stems and small, rounded leaves that can range in colour from bright green to shades of pink, red, or orange, depending on the lighting and nutrient conditions. Rotala rotundifolia is often used to create lush, dense backgrounds or midground accents in planted tanks, adding both height and a dynamic splash of colour to the aquascape. It thrives in a wide range of water conditions but displays its best colouration and growth under high light and with CO2 supplementation. Its relatively fast growth rate makes it an excellent option for filling in spaces quickly and creating a vibrant, living backdrop in any freshwater aquarium. With its aesthetic appeal and ease of care, Rotala rotundifolia is an ideal plant for both beginners and experienced aquarists looking to enhance the beauty of their underwater landscapes.
