Appearance

Amano shrimp are a medium-sized species, growing to an average length of 5-6 centimeters (2-2.5 inches). They feature a translucent body with a unique and eye-catching coloration. Sporting a range of earthy hues from brown to green, these shrimp often exhibit distinctive horizontal dotted stripes along their bodies. Their elongated, curved rostrum and prominent eyes make them instantly recognizable and a captivating addition to any tank.

Region

Originally hailing from the freshwater rivers and streams of Japan, Korea and Taiwan, Amano shrimp are well adapted to various water conditions. In the wild, they thrive in fast-flowing, well-oxygenated waters with ample hiding spots among aquatic vegetation and rocks. Recreating these conditions in your aquarium will ensure a comfortable and stress-free habitat for your Amano shrimp.

Behavior

Amano shrimp are renowned for their diligent algae-consuming behavior. They are natural cleaners, tirelessly scouring surfaces for algae growth and decaying matter. Their peaceful nature makes them excellent tank mates for a variety of community fish. Observing their constant movement and cleaning efforts can be both entertaining and beneficial for your tank’s overall health.

Diet

Amano shrimp are predominantly herbivores, with a voracious appetite for algae. Their diet should consist of a variety of plant-based foods, including high-quality algae wafers, spirulina pellets, and blanched vegetables such as zucchini or spinach. Providing a balanced and nutrient-rich diet is crucial for their well-being and ensures their effectiveness in keeping your tank clean. Many people keep them as a natural clean-up crew for their aquarium.

Keeping the Amano shrimp at home

Creating a suitable environment for Amano shrimp requires careful attention to water parameters, tank setup, and tank mates. Here are some essential tips to consider:

Tank size: Provide a tank with a minimum capacity of 38 liters (10 gallons) to accommodate a small group of Amano shrimp comfortably.
Water parameters: Maintain a temperature range of 20-26 degrees Celsius (68-79 degrees Fahrenheit) and a pH level between 6.5 and 7.5. A hardness level of 5-12 dGH is ideal.
Aquarium setup: Mimic their natural habitat with ample hiding spots, driftwood, and live or artificial aquatic plants. Maintain a gentle water flow using a sponge filter to simulate their preferred conditions.
Tank mates: Amano shrimp are peaceful and can coexist with a variety of community fish, such as tetras, rasboras, and gouramis. Avoid aggressive or larger species that may pose a threat to the shrimp.
Maintenance: Regular water changes of around 20% every two weeks, along with a balanced diet and algae control, will contribute to the health and longevity of your Amano shrimp.
