Actually, virtually any tropical plant can and will adapt to live rooted in an aquarium, which is effectively a well-oxygenated flowerpot full of fertilizer that never dries out. It's really an ideal way to grow many plants, not only peace lilies, bamboo, or pothos but many others as well. I have purple waffle plant, creeping fig, purple velvet plant, heartleaf philodendron, peace lily, syngonium, and aluminum plant (pilea) rooted directly in the tanks and I have some very long pothos vines that are potted in soil but which cross over the tank and are taking root in the water now too. I have also had great success with sweet potato vine, and only removed it because it grew too big - about an inch of stem and 2 inches of roots every day when it really got going!
The fish love hiding in the roots and it really helps mimic a natural riverbank environment like where the fish come from. The plants also pull up all the nitrogen and keep the water clean.
