I am absolutely no expert with plants, but my mother once brought me home some "Surprise plants" for my tank that were just horrid. I immediately cleaned them and put them in and they're now healthier than ever and so are my fish. I could have done something stupid and gotten lucky, though. Someone else probably has more knowledge and a better opinion.
