I hadn't seen it before either and I just had one sitting around! I asked the LFS worker and she said stores sometimes try to sell it to be planted submurged but it will melt immeadiately or die after about a month. She said they mostly sell it for ponds since it can get pretty big (like 6 ft!) but mine is only about 8 inches after 5 months so I think I have a few years before that happens.@JessicaSwanlake-I just got my mother one of those bella palms yesterday for her birthday!! I should have put it in my tank instead, lol. Those are so pretty. Now I need to go find one of those for me and hope I don't kill it in the tank. : ) Definitely keep us posted on how it's doing, I really like that idea.
