The Amano shrimp (Caridina multidentata) is from the family Atyidae. This algae-eating shrimp is found in the wild parts of Japan, Taiwan, and Korea. It is a freshwater shrimp as it inhabits freshwater marshes and streams.

The body of this algae-eating shrimp is transparent and has dots in a row that are reddish-brown in color. The eyes of this shrimp are large and black in color. It has long antennae and the legs are also nimble and long and the tail is broad and also transparent. It is easy to differentiate between a male and female Amano shrimp.

A male tends to get attracted to the female through scent and tries to mount the female Amano shrimp. After some time, the female will let the chosen male mate, and thus, fertilization of the Amano shrimp eggs takes place. Then, these eggs are released and these eggs go through the various stages in brackish water, that is, larval stages.  It has been recorded that in captivity, it is difficult to breed this shrimp, but when the female of this species releases pheromones, a male is housed in the same tank, and in heat, a male tends to swim around the female.

Their lifespan is known to be two to three years. Some other names for this shrimp include algae shrimp, Japanese shrimp, and Yamato shrimp. It is very gripping to know and learn about this shrimp and if you like read about shrimp and mantis shrimp, too.
