<p>Adds a very nice motion to your tank. Takes the smallest of current to move it. If you&#39;re not experienced with it, it does grow VERY quickly and needs to be cut back once in awhile.&nbsp;Due to the way it grows, which is a mat kind of form. I can&#39;t put a &quot; polyp &quot; count on it or a&nbsp;stalk count. It will be a&nbsp;generous amount worth your money. Will not be mounted, rubber band it to a rock or tuck it in your rock work. It will take hold within a couple days.</p>
