Amano Shrimp
Caridina multidentata
Family: Atyidae
📍 Japan, Taiwan & Korea
Named after legendary aquascape artist Takashi Amano who popularised their use, amano shrimp are the most effective algae-eating invertebrates available to hobbyists. Their large size and robust constitution means they can handle moderate current and tankmate activity. They do not breed in freshwater, so populations must be replenished from wild-caught stock.
