Tanakia koreensis is a species of fish in the family Cyprinidae. It is commonly known as the Korean bitterling. This species is native to Korea and parts of China.

Description

Tanakia koreensis is a small-sized fish, typically reaching a length of about 6-7 cm. The body is laterally compressed with a silvery hue, and during the breeding season, males exhibit vibrant colors to attract females. The species is known for its unique reproductive behavior, where females lay their eggs inside the gills of freshwater mussels.

Habitat

Tanakia koreensis inhabits slow-moving or stagnant waters such as ponds, lakes, and rivers. They prefer areas with abundant vegetation, which provides shelter and breeding grounds. The presence of freshwater mussels is crucial for their reproduction.

Reproduction

The reproductive strategy of Tanakia koreensis involves a symbiotic relationship with freshwater mussels. During the breeding season, males display bright colors to attract females. The female then deposits her eggs inside the gills of a mussel, where they are fertilized by the male. The eggs develop within the mussel's gills, providing protection until they hatch.

Diet

Tanakia koreensis primarily feeds on small invertebrates, algae, and plant material. Their diet consists of a variety of aquatic organisms, which they forage from the substrate and vegetation.

Conservation Status

The conservation status of Tanakia koreensis is currently not well-documented. However, habitat destruction and water pollution pose significant threats to their populations. Conservation efforts are needed to ensure the survival of this species, particularly in maintaining clean and healthy aquatic ecosystems.
