Amano Shrimp - Caridina Multidentata

True Amano Shrimp 

Caridina multidentata

The True Amano Shrimp (Caridina multidentata) is regarded as one of the most effective natural algae-eating shrimp available in the aquarium hobby. Originally native to Japan and surrounding regions of East Asia, these peaceful freshwater shrimp have become highly sought after by planted tank enthusiasts worldwide for their incredible appetite for algae, biofilm, and organic waste.

Unlike many ornamental shrimp, Amano Shrimp are larger, hardier, and excellent cleaners, making them an ideal addition to both beginner and advanced aquariums.

Filtration

• Spinach
• Indian Almond Leaves
• Fish foods
• Frozen foods occasionally

Avoid overfeeding.

Tank Mates

Suitable with:

✅ Other peaceful shrimp

Avoid:

❌ Large Cichlids

❌ Oscars

❌ Arowanas

❌ Puffers

❌ Large aggressive fish

Breeding

True Amano Shrimp have a unique breeding cycle.

Females carry hundreds of tiny eggs beneath their abdomen. After hatching, the larvae require brackish water to successfully develop before eventually returning to freshwater as juveniles.

Because of this specialised life cycle, breeding Amano Shrimp is considerably more challenging than breeding Cherry Shrimp.

Acclimation

Due to their sensitivity to sudden water changes, Amano Shrimp should always be drip acclimated.

We recommend:

• Float the bag for 15–20 minutes to equalise temperature.
• Slowly drip aquarium water into the container over 60–90 minutes.
• Gently net the shrimp into the aquarium.
• Do not add shipping water into your tank.

Care Tips

• Keep ammonia and nitrite at 0 ppm.
• Perform regular water changes.
• Avoid copper-based medications.
• Ensure plenty of hiding places, especially after moulting.
• Stable water parameters are more important than chasing perfect numbers.
