Ceratopteris thalictroides, commonly known as Water Sprite, is a fast-growing aquatic fern prized for its delicate, finely divided bright-green foliage. Its lush, feathery leaves create beautiful texture and make it an excellent choice for midground and background areas in freshwater aquariums. It can be planted in the substrate or grown as a floating plant, providing excellent versatility for different aquascaping styles. Moderate lighting and balanced nutrients encourage vigorous growth, while supplemental CO₂ can further improve density. Regular trimming helps control its size and maintain an attractive shape. Easy to grow and propagate, Water Sprite is ideal for creating lush, natural-looking planted aquariums.
