What is Caridina japonica Amano Shrimp?

As a species of freshwater shrimp, Caridina japonica Amano shrimp inhabit areas of Japan and Taiwan. Takashi Amano is the individual credited for the shrimp’s popularity, as he introduced it to the world as a natural algae-eating shrimp for aquariums.

Amano shrimp typically reach 2 inches in length. They have translucent bodies which can have either dots or stripes along their sides. While their looks can leave something to be desired, their utility as a cleaning and functional shrimp cannot be overstated.
