The Amur Bitterling, Rhodeus sericeus, is a small fish in the carp family. Bitterlings usually reside in areas with dense plant growth. They are a hardy fish and can survive in water that is not very well oxygenated. They grow to be 3-4in. long at most. The diet of a bitterling typically consists of plants and small insect larvae.
Bitterlings lay their eggs inside of mussels. Though it was long thought that it was a symbiotic relationship, it is in fact parasitic.
