Amano Shrimp (Caridina Multidentata)

The Amano Shrimp, scientifically known as Caridina multidentata and casually called Yamato shrimp, is a cornerstone of any thriving freshwater aquarium. Renowned for their hardiness, tireless activity, and impressive longevity, these shrimps are true workhorses for algae control and tank cleanliness. We offer both small and large specimens, so you can choose the perfect fit for your setup—from compact nano tanks to established display tanks.

Why this Caridina multidentata stands out

If you’re looking for a reliable, low-maintenance cleanup crew, the Amano Shrimp delivers. Their constant scavenging targets algae films, diatoms, biofilm on glass and plant leaves, and detritus, helping maintain clarity and balance in your aquatic environment. Unlike some invertebrates that peak early and slow down, Amano Shrimp stay active day after day, making them a dependable ally for long-term tank maintenance.

Key benefits at a glance

• Algae control that actually works. From stubborn hair algae to routine diatoms, these shrimp graze efficiently across glass, substrate, and plant surfaces.
• Hardy and adaptable. Built to tolerate a wide range of freshwater conditions and mix well in community and planted tanks.
• Long-lived and active. Expect years of steady performance and constant presence in your aquarium.
• Size options for different tanks. Available in small and large specimens to suit nano tanks as well as larger displays.
• Peaceful tankmates only. Gentle grazers that coexist with most peaceful fish and shrimp species when properly introduced.
• Low-maintenance care. Minimal special requirements beyond standard water conditions and a copper-free environment for medications.

Ideal for whom and what they solve

This species is particularly well-suited for planted tanks, densely stocked community tanks, and any setup where algae buildup is a concern. They’re ideal for hobbyists who want a dependable natural solution for algae management without resorting to chemical cleaners. If you’re building a balanced ecosystem and want an active, visible, hard-working cleanup crew, Amano Shrimp are a top choice.

Care essentials and practical tips

To ensure your Amano Shrimp thrive, consider these practical guidelines drawn from seasoned hobbyists:

• Water parameters: maintain a comfortable range of 68–78°F (20–26°C) and a neutral to mildly acidic pH (roughly 6.5–7.5). They tolerate moderate hardness but appreciate stable, consistent conditions.
• Acclimation matters. Introduce them gradually to reduce stress. A slow drip acclimation over 1–2 hours helps them adjust to new water chemistry.
• Feeding approach. While they actively hunt algae and biofilm, supplement with occasional sinking algae wafers, blanched vegetables (spinach, zucchini), or seafood-based pellets to boost nutrition in tanks with sparse natural food sources.
• Avoid copper-based medications. Amano Shrimp are copper-sensitive. If your tank ever needs treatment, choose copper-free options or remove the shrimp temporarily during medication.
• Tank setup considerations. Provide plenty of surfaces to forage—glass, plant leaves, driftwood, and substrate seams are all favored for grazing. Gentle water flow helps carrying food to them without stressing more delicate species.
• Breeding note. In freshwater, successful breeding is rarely observed, so you’ll typically enjoy a robust, single-generation cleanup crew rather than a booming shrimp colony.

Compatibility and care philosophy

Peaceful by nature, Amano Shrimp pair well with small, non-aggressive fish and other compatible invertebrates. They’re not suited for tanks with fish that actively prey on shrimp or large, aggressive species. In a thoughtfully assembled community, these shrimp quietly go about their business, keeping surfaces clear and your plants healthier by reducing algae competition.

What makes this offering unique

Beyond their iconic status and algae-eating prowess, our Amano Shrimp selection emphasizes the practicality of real-world aquarist needs: choose the size that best fits your tank, benefit from a robust species known for longevity, and enjoy a specimen that remains actively engaged in tank maintenance for years. The Caridina multidentata you receive is a proven, dependable ally—ready to contribute to a clearer, more balanced aquarium from day one.
