"Caridina multidentata" is a species of shrimp found in the Yamato River area of Japan as well as parts of Korea and Taiwan. It was previously known as "Caridina japonica" but was renamed "Caridina multidentata" following a study in 2006 [cite news |url=http://www.practicalfishkeeping.co.uk/pfk/pages/item.php?news=1078 |publisher=Practical Fishkeeping |title=Amano shrimp gets new name |date=2006-09-21 |author=Matt Clarke] .

According to different sources, "Caridina multidentata" was introduced into the world of aquaria by Takashi Amano in the early 1980s. Takashi Amano is a well known photographer and aquarist. He would have been the first who noticed these shrimps' useful characteristic of eating algae and started using them in his show aquaria.

The most important characteristic of "Caridina multidentata" is the 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.

They are usually used in an aquarium because they feed primarily on algae, thus cleaning the aquarium if in large numbers.

It should be noted that if keeping these shrimp, copper based water additives or medicines should never be used.
