The Water Sprite, also known as the Indian Fern, is a great plant to use as a mid-ground plant and also as a floating plant. The delicate, lacy leaves also make great cover for fry to hide among. Due to its poor root system, the Water Sprite retrieves nutrients from the water. The Water Sprite will grow profusely under the correct conditions, and for this reason, is excellent at removing unwanted and unhealthy inorganic nutrients from the aquarium water. In smaller aquariums with open tops, the Water Sprite can grow out of the tank and form beautiful surface leaves.
