Cherry Shrimp vs Amano Shrimp: Which One Do You Actually Need?

Shrimp have always fascinated me, and I still remember the first time I added them to my aquarium. At that moment, I thought, “These are just cute little cleanup critters, right?” But within a few weeks, I started noticing something interesting. The cherry shrimp were multiplying quickly, while the Amano shrimp were constantly busy cleaning algae like true professionals.

That’s when it clicked for me, choosing the right shrimp isn’t just about looks, it’s about what role you want them to play in your tank.

Cherry Shrimp vs Amano Shrimp — Key Differences

Before we proceed with a detailed comparison of these two shrimp species, let’s first get to know them better. This will help us form the right perspective regarding these shrimp for our own aquariums.

🔴 Cherry shrimp (Neocaridina davidi)

Cherry shrimp, found in the slow-moving freshwater streams of Taiwan, thrive amidst dense vegetation and stable water conditions. Their vibrant coloration, ranging from a pale pink in lower-grade specimens to a deep, intense red in higher-grade ones, truly makes them exceptionally beautiful creatures. However, this magnificent appearance is actually the result of selective breeding; in their natural habitat, wild Neocaridina species typically appear quite pale and brownish in color.

Cherry Shrimp (Neocaridina davidi)

• Bright red (and other colors)
• Small size (~1–1.5 inches)
• Very easy to breed in freshwater
• Beginner-friendly

Amano shrimp (Caridina multidentata, previously known as Caridina japonica)

They originate from parts of Japan, Taiwan, and Korea. They were popularized by the renowned aquarium expert Takashi Amano, and are now named in his honor. In nature, Amano shrimp inhabit fast-flowing, oxygen-rich streams and rivers, a fact that indicates their preference for well-filtered, oxygenated aquarium water.

It is precisely because of these distinct natural habitats that their care requirements, behavior, and compatibility with other tank inhabitants differ in ways that hold significant practical importance for every aquarist.

Amano Shrimp (Caridina multidentata)

• Transparent/grey with dots
• Larger size (~2–2.5 inches)
• Excellent algae eaters
• Difficult to breed (requires brackish water)

📊 Scientific Insight: Amano shrimp gained popularity due to aquascaper Takashi Amano, who used them extensively for algae control in planted tanks.

Size Comparison — Cherry Shrimp vs Amano Shrimp Size

In my opinion, the difference in size between these two shrimp impacts everything from their ability to coexist in the tank to their feeding habits and dominance dynamics.

Cherry shrimp size: For beginners, keeping them in a nano tank can be the best choice. Cherry shrimp are small in size, with females measuring approximately 1.5 inches long and males approximately 1 inch long.

Amano shrimp size: Amano shrimp are significantly larger than Cherry shrimp; adults can reach approximately 2 inches, or, under optimal conditions, up to 2.5 inches. Due to their size, they have a greater capacity to consume algae.

According to research published in the ‘Journal of Crustacean Biology’, the body size of freshwater shrimps is directly related to their feeding rate. Larger shrimp cover a larger area and consume a significantly greater amount of algae and biofilm per shrimp, per day.

Which Is Better at Eating Algae?

The answer to this question is crystal clear: Amano shrimp. If the primary reason for adding shrimp to your tank is to control algae, this factor should have a profound impact on your decision.

Amano shrimp are significantly more effective algae eaters than cherry shrimp. Amano shrimp are particularly effective against:

• Hair algae and thread algae — which many other algae eaters ignore
• Staghorn algae — one of the most difficult algae types to control
• Green dust algae on glass and hardscape
• Biofilm and green spot algae on broad plant leaves

Cherry shrimp do eat algae, but they do not consume tough algae; they primarily graze on soft biofilms, green dust algae, and microscopic algae accumulated on plant leaves. Read the detailed guide here: Best Algae Eater Shrimp?

Which Is Better for Beginners?

Choose cherry shrimp if you:

• Have a smaller tank or nano tank (5–20 gallons)
• Want colorful, beautiful, active shrimp that breed and grow into a visible colony
• If you are new to shrimp keeping and want a forgiving species
• Enjoy watching shrimp behavior and colony dynamics
• Have a planted nano tank setup

Choose Amano shrimp if you:

• Have persistent algae problems — particularly hair algae or staghorn algae
• Have a larger planted tank (20 gallons and above)
• Want hardy shrimp that tolerate a wider range of water conditions
• Do not need the shrimp to breed — you just want effective algae control
• Already keep fish that might pick at smaller shrimp

Choose both if you:

• Have a tank of 15 gallons or larger with dense planting
• Want both algae control and the visual appeal of a growing shrimp colony
• You are experienced and good enough to manage the slightly different water parameter needs of both species

2020 survey conducted by Aquatic Arts: Largest freshwater shrimp suppliers in the United States, cherry shrimp consistently rank as the number one, while Amano shrimp rank second.

Can Amano Shrimp and Cherry Shrimp Live Together?

Yes, Amano shrimp and cherry shrimp are peaceful species by nature and can absolutely live together in the same tank. Amano shrimp and cherry shrimp in the same tank are very common.

Why do they coexist well?

• Both are non-aggressive
• Similar water parameters
• Different roles (cleaning vs breeding)

💡 My experience:
Amano shrimp act like “cleaners,” while cherry shrimp add color and activity.

However, there are practical conditions that make this coexistence work smoothly, such as Tank size matters, Hiding spots are essential, and Water parameters need a compromise.

Amano and Cherry Shrimp in the Same Tank (Setup Tips)

If you plan to keep amano and cherry shrimp together:

Ideal Conditions:

• Ideal Water Temperature: 68–78°F
• pH: 6.5–7.5
• Plenty of plants and hiding spots

Pro Tips:

• Add moss (great for baby shrimp)
• Provide stable water parameters
• Avoid aggressive fish

Will Amano Shrimp Eat Cherry Shrimp?

This is one of the most searched questions, and here’s the honest answer:

👉 No, Amano shrimp do not actively hunt cherry shrimp.

However:

• Amano shrimp can attack newly molted cherry shrimp
• They may eat dead or weak shrimp
• Very small baby shrimp could be at slight risk
• In Underfed tanks, this might create more risk.

👉 The practical conclusion from my research and from the wider aquarium keeping community: In a healthy tank, they are completely safe tank mates.

Will Amano and Cherry Shrimp Breed Together?

No, Amano shrimp and cherry shrimp cannot interbreed. They belong to completely different genera (Caridina and Neocaridina, respectively) and are not genetically compatible with each other. There is no hybrid between these two species possible under any circumstances.

• Cherry shrimp = Neocaridina species
• Amano shrimp = Caridina species

📊 Scientific classification confirms these species are biologically incompatible for breeding.
