Amano Shrimp: Nature’s Hardworking Algae Eater
The Amano Shrimp (Caridina multidentata), also known as the Yamato Shrimp, is one of the most popular freshwater shrimp in the aquarium hobby. First introduced to aquarists by the famous aquascaper Takashi Amano, these shrimp are prized for their incredible algae-eating abilities, peaceful nature, and usefulness in planted tanks.
Appearance
Amano Shrimp are medium-sized compared to other dwarf shrimp species, growing up to about 2 inches in length. Their bodies are translucent with a grayish or greenish tint, often decorated with rows of small dots or dashes along their sides. While not as colorful as some ornamental shrimp, their utility and subtle beauty make them highly sought after.
Care Requirements
Amano Shrimp are hardy and relatively easy to care for, making them a great choice for both beginners and experienced aquarists.
* Tank Size: 10 gallons or larger is ideal.
* Water Parameters: pH 6.5–7.5, GH 4–8, KH 2–6.
* Temperature: 68–78°F is suitable.
* Filtration: Gentle filtration with plenty of oxygen and clean, stable water conditions.
* Substrate: Sand or fine gravel works well, especially when paired with plants and driftwood.
Diet
Amano Shrimp are famous for being some of the best algae eaters in the aquarium hobby. They consume many types of algae, including soft green algae and hair algae, making them excellent natural cleaners. In addition, they should be supplemented with:
* High-quality shrimp pellets or algae wafers
* Blanched vegetables like zucchini, cucumber, and spinach
* Occasional protein-rich foods to support health
Tankmates
These shrimp are peaceful and do best in community aquariums with non-aggressive species. Avoid housing them with large or predatory fish. Ideal companions include:
* Small tetras, rasboras, and danios
* Peaceful livebearers like guppies or mollies
* Other dwarf shrimp and snails
Breeding
Unlike Neocaridina or other Caridina shrimp, breeding Amano Shrimp in freshwater is extremely difficult. Their larvae require brackish water conditions to survive and develop into juvenile shrimp. Because of this, most Amano Shrimp available in the aquarium trade are wild-caught.
Why Keep Amano Shrimp?
Amano Shrimp are highly valued not just for their algae-eating abilities, but also for the activity and balance they bring to an aquarium. They constantly forage, keeping plants, rocks, and decorations free of unwanted growth. For aquascapers, they are an essential member of the clean-up crew.
If you’re looking for a reliable and hardworking shrimp to maintain a healthy, algae-free tank, the Amano Shrimp is one of the best choices you can make.
