Family: Pteridaceae Common Name: Water Sprite Maximum Height: 6 inches to 8 inches Leaf Size: 3 inches to 8 inches Stem Thickness: 1/16 inch Light: Strong Temperature: 68 to 82 degrees Fahrenheit pH: 5.0 to 9.0 Origin: Tropical Regions Water Hardness: Soft to Hard Nutrients: Ample Nutrients; CO2 Recommended Relative Growth  Speed: Fast if floating; Moderate if submerged. Plant Profile This is a fast-growing floating plant that requires a high level of nutrients and appreciates strong light. Floating in a fertilized aquarium, where it is close to the light, it flourishes. Cuttings can be planted in substrate or tied to driftwood, but growth will substantially slow. Adding CO2 is helpful, but not necessary. Some folks will grow batches on the surface and take cuttings to occasionally replace specimens planted in substrate this way maintaining an optimal appearance while keeping specimens at the lower levels of the aquascape.
