Amano Shrimp Caridina multidentata (prev. japonica)

The Amano Shrimp is native to freshwater streams and marshes of Japan, Taiwan and, possibly, Fiji. There are over 250 similar shrimps in their genus and claims that they live from Madagascar to Fiji, but these are mostly different species. Although the adults live in freshwater, they need to release eggs in brackish water and the larvae live in brackish or salt water until maturity.

They are translucent, like many shrimp, with broken red lines on the flanks and a white dorsal line. The top of the rostrum is curved rather than straight. They are good cleaners, rasping on algae and have a voracious appetite for dead plant and animal material.
