Amano Shrimp

Caridina multidentata

Temperament

Peaceful and active. Amano Shrimp spend their days exploring plants, wood, and rocks in search of algae and biofilm. They make excellent community residents alongside gentle tankmates, though they may enthusiastically claim their share at feeding time.

Adult Size

Adults reach approximately 2 in (5 cm), with females generally larger than males. Their translucent bodies feature rows of reddish-brown dots and dashes for a subtle, natural look.

Compatible Tankmates

• Small, peaceful fish such as ember tetras, chili rasboras, otocinclus, and pygmy corydoras
• Peaceful snails and dwarf shrimp when water requirements overlap
• Avoid: large or aggressive fish and any fish capable of swallowing a shrimp. Bettas may harass shrimp, depending on individual temperament.

Planted-Tank Role

A hardworking addition to your freshwater clean-up crew. Amano Shrimp graze soft algae, including many types of hair algae, along with biofilm and leftover food. They help keep plant leaves and hardscape tidy without damaging healthy plants. Moss, driftwood, and dense planting provide shelter, especially after molting.

Feeding

• Offer shrimp-specific pellets or algae wafers as needed to supplement natural grazing.
• Small portions of blanched zucchini or spinach add variety.
• Adjust feeding to the amount of algae available and remove leftovers before they foul the water.
• Algae alone may not provide enough nutrition.

Water Parameters

• Temperature: 65–80 °F (18–27 °C), with a stable mid-70s temperature suitable for many community setups
• pH: 6.5–8.0
• GH: approximately 6–12 dGH
• Keep ammonia and nitrite at zero and introduce shrimp only to a fully cycled aquarium.
• Acclimate slowly, avoid sudden changes in water chemistry, and avoid copper-based medications that are unsafe for invertebrates.

Stocking Guidance

• A mature aquarium of 10 gallons or more is a good starting point for a small group of 3–5 Amano Shrimp.
• Adjust stocking to available grazing space, filtration, and existing tankmates.
• Provide hiding places and cover filter intakes.
• Unlike Red Cherry Shrimp, Amanos will not establish a breeding colony in a typical freshwater aquarium. Their larvae require specialized brackish-to-marine rearing conditions.
