Amano shrimp are known for their ability to consume algae, including the troublesome black brush algae. However, they usually prefer fish food over algae, and a large number of them may be required to have a significant impact. If you see them at the surface often, it may be due to a lack of oxygen or high nitrate levels.

These shrimp moult approximately once a month, seeking a hiding spot for safety while their new shell hardens. Some inexperienced aquarists might assume their shrimp have been eaten during this process, but they usually reappear after a few days.

While Amano shrimp are peaceful in temperament, they can be greedy feeders and may steal food from smaller shrimp. They do not attack other aquarium inhabitants, and will actively forage and clean the tank of algae when predators are absent. Suitable tankmates include peaceful species such as cardinal tetras, guppies, and dwarf cichlids.
