I have a 36G bowfront (21" high, 12-15" wide) that I want to be a planted community. It will have medium light, plan on dosing with flourish and excel, and use root tabs for anything in the substrate. I really want to try a sword, just not have a monster plant take over my tank. My original thought is a melon sword. I like the color, nice round leaves, and it grows up. Any experience with them or suggestions on others?
