Amano Shrimp

Amano Shrimp (Caridina multidentata) are freshwater aquarium shrimp native to East Asia, especially Japan and Taiwan, where adults live in clean freshwater streams and river systems connected to downstream coastal waters. Their natural life cycle is amphidromous, meaning newly hatched larvae drift into brackish or marine environments before developing and returning upstream as juveniles.

This species is larger and more active than many dwarf aquarium shrimp, with a translucent body, fine spotting, and a constant grazing behavior that makes it easy to watch in planted aquariums. Amano Shrimp are peaceful invertebrates and do best with calm community fish that will not harass or eat them.

In aquariums, Amano Shrimp are valued for their steady activity, natural algae-grazing behavior, and ability to add movement without dominating the layout. They are especially useful in planted tanks, shrimp-safe community setups, and aquascapes where small, hardworking invertebrates fit the overall system.
