Caridina multidentata, also known as Yamato shrimp or Amano shrimp, is a species of shrimp found in Japan and parts of Korea and Taiwan. It has a translucent body covered with reddish brown points of ± 0. 3 mm on their sides which may look like a broken line of reddish colour. The dorsal surface has a white stripe that runs from the head to the tail and the eyes are black. Females are easily distinguished from males from the more elongated lower row of dots lining the body. According to different sources, Caridina multidentata was introduced into the world of aquaria by Takashi Amano in the early 1980s. They are usually used in an aquarium because they feed primarily on algae, thus cleaning the aquarium if in large numbers.
