I had some a couple years ago. They spread fast but I didnt have very many. Planning on put them on a floating island type of thing. Will watch them for sure. If they start to get carried away I will remove some for sure. Here they die off in the fall also. Even tired to keep some on my shop over the winter and they died also. But as always thanks 4 the heads up I will keep an eye on them.

The people who say I can't do it can just sit the @^#% down and watch me. Friends call me Rusto I also subscribe to pond boss mag. http://forums.pondboss.com/ubbthreads.php?ubb=showflat&Number=504716#Post504716
