Rosy Bitterling
Rhodeus ocellatus
The rosy bitterling is a small East Asian cyprinid known for the male’s rosy breeding colors and a dark spot at the base of the dorsal fin. It is closely tied to freshwater mussels for spawning and is best known as an aquarium and conservation species rather than a sport fish.
