i saw something the other day at an lfs, it was midway up in tank , green , and swayed with the current like grass................i asked what it was and the guy said its a green wave? never heard of this , so i didnt buy it........id rather get it somewheres else frankly.....................maybe its called by something else? cuz i cant find anything by that name..........................i wasnt star polyp or flower pot coral, it was more like grass or seaweed but bright green
