Amano Algae Eating Shrimp
Couldn't load pickup availability
Japonica shrimp, or amano shrimp, are great algae eaters and terrific in community tanks. These shrimp are among the most popular at AquariumFish.com; they grow to about 2 inches and develop a light blue color.
The great planted tank pioneer Takashi Amano brought these shrimp to the aquarium hobby, and eventually the shrimp acquired his name for their own.
Amano shrimp are wild-caught in the highlands of Taiwan. Fortunately, we also have a breeder in Taiwan to supplement our inventory during monsoon season.

Care Guide
Tank setup: Give them a cycled, planted tank with moss, driftwood and hiding spots. Cover filter intakes with a sponge and keep a lid on the tank, since amanos can climb out.
Feeding: Amanos eat algae and leftover food. If algae runs low, feed algae wafers or shrimp pellets.
Tankmates: Amanos do well with most peaceful community fish, plus other shrimp and snails. Avoid cichlids, goldfish, loaches and other fish large enough to eat them.
Good to know: Amano shrimp breed in captivity, but their larvae need brackish water to develop, so they will not overpopulate a freshwater tank.
