And heres a photo of my small red lotus, which isnt looking very good as it has just spent three days in a bag on its way to me 
Overall, this plant is a very beautiful plant, and is a must in any planted tank. the green variety is very easy to grow under adequate lighting, and the red variety being a big harder, is not usually recommended for beginners (because of its rarity) and is often hard to get hold of.
