The Amano shrimp (Caridina multidentata) is a freshwater shrimp best known for its exceptional algae-eating abilities. Named after aquascaper Takashi Amano, it is a popular addition to planted tanks and community aquariums due to its industrious nature and peaceful temperament. Overview of Amano shrimp Appearance: Amano shrimp have a translucent, grayish body, with a line of reddish-brown or blue-gray dots or dashes along each side. Females are generally larger and have dashes, while the smaller males have dots. Size: They grow larger than most other dwarf shrimp, reaching up to 2–2.5 inches in length. Lifespan: With proper care, they can live for 2–3 years. Temperament: Amano shrimp are peaceful, active foragers and good swimmers. They are constantly grazing for biofilm and algae but can be assertive during feeding time with other shrimp. Escape artists: They are known to climb out of tanks, so a secure lid is recommended. Breeding: They are difficult to breed in a typical freshwater aquarium because their larvae require brackish water to survive. Habitat and care requirements Tank size: A minimum tank size of 10 gallons is recommended for a small group of Amano shrimp to allow enough space for foraging. Water parameters: Amano shrimp are hardy and can tolerate a wide range of water conditions, but they prefer stable parameters. Temperature: 68−78∘ 68−78∘ F ( 20−26∘ 20−26∘ C). pH: 6.0–7.6. Filtration: A gentle filter, such as a sponge filter, is ideal. Tank setup: Amano shrimp need a well-established tank with plenty of hiding places, such as live plants (like Java Moss or Anubias), driftwood, and rocks, especially after molting. Tank mates: They are compatible with other peaceful, similarly sized invertebrates and fish that won't prey on them. Safe options include: Other dwarf shrimp Snails Small, peaceful fish like Corydoras, Otocinclus, and small Tetras Water quality: They are very sensitive to sudden water changes and pollutants, especially copper, which is toxic to invertebrates. Always use a water conditioner when performing water changes. Diet Amano shrimp are opportunistic omnivores that primarily feed on biofilm, detritus, and algae. Primary food source: They are famous for controlling algae, including green hair algae, brown diatom algae, and soft algae. Supplementation: If there isn't enough algae in the tank, you can provide supplemental food: High-quality algae wafers and shrimp pellets Blanched vegetables, such as zucchini and spinach Calcium-rich foods or supplements to aid in healthy molting. Protein-rich options like brine shrimp or daphnia can also be offered occasionally.
