Description
The oily bitterling is a small cyprinid relative (Acheilognathidae) from clear rivers, ponds and ditches of Japan and Korea in East Asia. The species grows to about 6 cm and has a deep, silvery body that flushes orange and blue-green in spawning males. Distinctively, the female uses a long ovipositor to lay the eggs inside the gill cavity of a living freshwater mussel, where the young grow up safely. It eats algae, small invertebrates and detritus. The fish is harmless to humans.
