I was browsing through some pictures and saw what seemed to be grass on the bottom of an aquarium. I thought it was cool because it looked really nice and no more gravel vacums because all the waste would go to the bottom and the plant would use it like fertilzer, right? Does anyone know what this plant is called? I realy want some for my tank. Im guessing I would need more lighting too because the plant is on the bottom of the tank. Thanks for any help!
