I'm looking for a plant suitable for a ground cover in the foreground of my tank (20 gal). I've seen ideal plants that form a 'carpeted' affect in Amano's Tanks but I'm not sure of their names. If anyone knows of a plant that fits these requirements, aswell as being moderately fast-growing and suitable for low light (1.5 watts/gallon), please reply to this message. Thanks in advance, Keely Bays
