👉 Lethotremus is a genus of freshwater fish in the family Cyprinidae, which includes several species commonly known as "whites." These fish are native to various parts of Asia and Europe, particularly China and Japan. They are primarily found in fresh bodies of water like rivers, lakes, and ponds, but they can also be found in saltwater environments. Lethotremus is characterized by their distinctive white coloration, which helps them blend into the surrounding environment.
