Sinanodonta woodiana is a Unionidae freshwater mussel, East Asia's classic river mussel and the traditional host of bitterling. In the aquarium it is a harmless filter feeder that clears green water. Plan on a 10–15 cm shell at 15–26 °C in a mature tank; it needs suspended foods and stable, unheated-tolerant conditions.
