I am looking to replace a background sagittaria subulata on my 12gl fluval edge (video here <http://www.youtube.com/watch?v=-eNcrOREl0g> because it grows way too fast and keeps shooting out runners all over. I am looking for a red tall plant that would add some color and be easy to maintain. It needs to be small and grow tall up to 12-13 inches (a red tiger lotus for example wouldn't work because it spreads too wide). A slow grower would be appreciated. Any plant experts here that can recommend options? Thanks!
