cute little grassy looking plant. my cories like to hide under the leaves. Mine grows very fast in sand (crushed marble) with new runners all the time. I don't fertilize it and I have about 1.7 watts/gal with some afternoon sunlight. No CO2 added. Easy and small. Good if you want to try an aquatic plant for the first time.

This is actually an aquatic plant, used in fish tanks! I grow mine in a fish bowl by itself, and it makes a lovely focal point. The plants shoot out runners quickly and form a beautiful carpet that's grass like in appearance. It grows about 8 inches tall, depending on the lighting conditions, some say with high light it can get 16inches. It does do better with iron fertilizer in the substrate, and will tolerate brackish conditions. Us aquatic plant geeks just call it Dwarf Sagittaria, or Narrow Leaf Sag. but on a USDA site it lists Sagittaria subulata as awl-leaf arrowhead. Who knew. =) Mine will shoot up neat little white blooms above the surface of water, which is always a nice surprise!
