Amano Shrimp (Caridina multidentata)
The Amano Shrimp is one of the most popular freshwater shrimp species in the aquarium hobby, known for its exceptional algae-eating abilities and hardy nature. Named after the famous aquascaper Takashi Amano, who introduced them to the aquarium world, these shrimp are highly valued for their ability to control algae and maintain a clean tank environment.
Appearance
Amano Shrimp have a semi-transparent, grayish body with a series of dark spots or dashes running along their sides. Unlike colorful Neocaridina and Caridina shrimp, Amano Shrimp are more subtly patterned but still visually appealing, especially in planted tanks. Their size is also larger than most dwarf shrimp, reaching up to 2 inches (5 cm) in length.
Tank Requirements
Tank Size: Minimum 10 gallons, but larger tanks are preferred for groups.
Water Parameters:
Temperature: 65–80°F (18–27°C)
pH: 6.5–7.5
GH: 6–8
KH: 2–5
TDS: 150–250 ppm
Filtration: Sponge filters or gentle-flow filters work best.
Substrate: Neutral or dark-colored substrates enhance their appearance.
Plants & Hiding Spots: Live plants, driftwood, and mosses provide shelter and additional grazing surfaces.
Diet
Amano Shrimp are omnivores with a strong preference for algae but also consume other organic matter:
Staple Foods: Algae, biofilm, and decaying plant matter.
Supplementary Foods: Algae wafers, shrimp pellets, blanched vegetables (zucchini, spinach), and protein-based treats like bloodworms.
Behavior & Compatibility
Temperament: Peaceful and social; best kept in groups of 5 or more.
Tank Mates: Ideal for community tanks with peaceful fish such as tetras, rasboras, and guppies. They also coexist well with other shrimp and snails but should not be kept with large or aggressive fish.
Breeding
Unlike most freshwater shrimp, Amano Shrimp have a complex breeding process. Their larvae require brackish water to develop, making home breeding extremely difficult. In freshwater tanks, females will carry eggs, but the larvae will not survive without proper salinity changes.
Conclusion
The Amano Shrimp is an excellent algae eater and a hardy, peaceful addition to both planted and community tanks. Their low-maintenance care, ability to control algae, and active nature make them a must-have for aquarists looking to maintain a clean and balanced aquarium.
