Not to be confused with Rhodeus amurensis, whose scientific name literally means "Amur bitterling"

The Amur bitterling (Rhodeus sericeus) is a small fish of the carp family. It is sometimes just called "bitterling", which dates back to the time when the European bitterling (Rhodeus amarus) was still considered conspecific with R. sericeus, and "bitterling" properly refers to any species in entire genus Rhodeus. The Amur bitterling is found in Siberia, while the European bitterling is found from European Russia westwards.
