Rip 05-03-2011 06:52 PM many stem plants can be used as floating plants, such as anacharis and water wisteria. the wisteria floats on it is own. the anacharis might sink slightly, and to keep it from moving around in the water, i pinch the tip of the stem under the tank's hood to hold it in place. water sprite is another popular floating plant, although i have never been able to find it locally. wist
