Ghost Vs Amano Shrimp – The Ultimate Guide To Choosing Your Tank’S

Written ByHoward Parker

Walking up to the shrimp tank at your local fish store can be a little daunting, can’t it? You see two popular, nearly-transparent critters scooting around, and the labels say “Ghost Shrimp” and “Amano Shrimp.” They both look like great additions to your cleanup crew, but which one is truly right for your aquarium?

I get it. Making the right choice feels important because it is! The right shrimp can turn your tank into a pristine, self-managing ecosystem, while the wrong one might not meet your expectations or, worse, cause problems.

Promise me this: by the end of this guide, you will have the confidence and expert knowledge to decide. We’re going to break down the entire ghost vs amano shrimp debate, covering everything from their algae-eating power and temperament to their specific care needs and even how to tell them apart. Let’s find the perfect invertebrate janitor for your tank!

Meet the Contenders: A Quick Introduction

Before we dive deep, let’s get properly acquainted with our two competitors. While they might look similar from a distance, they come from very different backgrounds and play slightly different roles in an aquarium.

The Ghost Shrimp (Palaemonetes paludosus)

Often called the “Glass Shrimp,” this little guy is the budget-friendly champion of the aquarium world. They are native to North America and are known for their almost completely transparent bodies, which is how they got their spooky name!

Ghost shrimp are primarily scavengers. They’ll happily munch on leftover fish food, decaying plant matter, and some types of soft algae. They are often sold as live food for larger fish, but don’t let that fool you—they make fascinating and useful pets in their own right.

The Amano Shrimp (Caridina multidentata)

Named after the legendary aquascaper Takashi Amano, who popularized their use, Amano shrimp are the undisputed superstars of algae control. Hailing from Japan and Taiwan, these shrimp are slightly larger and more robust than their ghostly cousins.

Amanos are voracious algae eaters with an appetite that is second to none. If you’re battling hair algae, biofilm, or other common tank nuisances, the Amano shrimp is a tiny, tireless powerhouse you’ll want on your team.

Appearance Showdown: Telling Ghost and Amano Shrimp Apart

At first glance, telling these two apart can be tricky. But once you know what to look for, you’ll be able to spot the difference in seconds. This part of our ghost vs amano shrimp guide is all about the details.

Ghost Shrimp:

  • Transparency: They are almost completely see-through. You can often see their internal organs at work!
  • Back: Their back has a distinct arch or hump, unlike the smoother curve of an Amano.
  • Markings: They have very subtle markings, often just a few tiny, faint orange or yellow dots on their antennae and tail.
  • Claws: Look closely! Ghost shrimp have two small, visible claws, which they use to forage.

Amano Shrimp:

  • Body Shape: Amanos have a straighter, more torpedo-like body shape.
  • Coloration: While still translucent, their bodies have a grayish or brownish tint.
  • Markings: This is the dead giveaway. Amanos have a distinctive pattern of solid dots and dashes running along the length of their bodies. Males tend to have more dots, while females have more dash-like lines.
  • Size: A healthy adult Amano can reach up to 2 inches (5 cm), making them noticeably larger than the average 1.5-inch Ghost shrimp.

The Great Algae Debate: Who Is the Better Cleaner?

This is the main event for many aquarists. You want a clean tank, so which shrimp pulls more weight? The answer depends entirely on what you need cleaned.

The Amano’s Algae-Eating Prowess

When it comes to eating algae, the Amano shrimp is in a league of its own. They are relentless grazers with a broad palate. Think of them as your specialized task force.

Amanos are fantastic for tackling:

  • Hair Algae and Thread Algae: They will tirelessly pick at and consume these stringy nuisances.
  • Black Beard Algae (BBA): While they won’t clear a heavy infestation, they are one of the few creatures that will readily eat BBA, especially when it’s young.
  • Biofilm: They are excellent at cleaning the invisible layer of bacteria and microorganisms that grows on surfaces.
  • General Detritus: They will also happily clean up leftover food and decaying plant leaves.

The Ghost Shrimp’s Scavenging Skills

The Ghost shrimp is more of a generalist janitor than a specialist algae assassin. Their primary role is scavenging leftover food that your fish miss.

Ghost shrimp are best for:

  • Uneaten Fish Food: They prevent flakes and pellets from rotting and fouling your water.
  • Detritus and Waste: They will pick through the substrate, cleaning up decaying matter.
  • Some Soft Algae: They may nibble on very soft algae, but it’s not their preferred food source. Don’t count on them to clear an existing algae problem.

The Verdict: For pure algae-eating power, the Amano shrimp wins, hands down. For general-purpose scavenging and preventing waste buildup at a lower cost, the Ghost shrimp is a solid choice.

Temperament and Tank Mates: Who Plays Nicer?

Both shrimp are generally peaceful, but there’s a huge “gotcha” you need to be aware of, especially when it comes to Ghost shrimp. This is one of the most important ghost vs amano shrimp tips I can offer.

The Peaceful Amano

Amano shrimp are incredibly peaceful and industrious. They spend their days minding their own business, grazing on surfaces. They are not aggressive and pose zero threat to any fish, even tiny fry. Their larger size also makes them slightly less tempting as a snack for curious fish.

The “Ghost Shrimp” Imposter Problem

True Ghost shrimp (Palaemonetes species) are peaceful scavengers. However, they are often confused with or mixed in with a different, more aggressive species called the “Whisker Shrimp” (Macrobrachium species).

These imposters look very similar when young but grow larger, develop much longer claws, and can become predatory. If you’ve ever heard a horror story about a “Ghost shrimp” attacking and killing a small fish like a guppy or tetra, it was almost certainly a Whisker shrimp.

Pro Tip: To avoid this common problem, buy your Ghost shrimp from a reputable source. Look for shrimp with small, equal-sized claws. If you see one with noticeably long arms and larger pincers, steer clear!

A Complete Ghost vs Amano Shrimp Care Guide

Ready to bring some shrimp home? Don’t worry—both are quite hardy and great for beginners! Here’s a breakdown of their care requirements to ensure you’re following the best practices.

Water Parameters

Both shrimp are adaptable, but they thrive in a stable, mature aquarium. Avoid adding them to a brand-new, uncycled tank.

  • Temperature: 65-82°F (18-28°C) is a comfortable range for both.
  • pH: A stable pH between 6.5 and 8.0 works well.
  • Hardness: They need some minerals (GH and KH) in the water to help with their shells during molting. Aim for a GH of at least 6 dGH.
  • Ammonia/Nitrite/Nitrate: Like all invertebrates, they are extremely sensitive to ammonia and nitrite (should always be 0 ppm) and sensitive to high nitrates (keep below 20 ppm).

Diet and Feeding

Even though they are cleaners, you still need to make sure they’re getting enough to eat, especially in a very clean tank.

Supplement their diet with high-quality shrimp pellets, algae wafers, or blanched vegetables like zucchini and spinach. This ensures they get the calcium they need for healthy molting, one of the most critical aspects of their care.

Tank Size and Environment

Amano shrimp are more active and slightly larger, so they appreciate a bit more room. A 10-gallon tank is a good minimum for a group of Amanos. Ghost shrimp can be happy in tanks as small as 5 gallons.

Both species need places to hide, especially when they are molting and vulnerable. Live plants, driftwood, and small caves are perfect for helping them feel secure.

Breeding in the Home Aquarium: A Tale of Two Difficulties

If you’re dreaming of a self-sustaining shrimp colony, this is a critical difference to understand.

Ghost Shrimp: They breed very easily in a standard freshwater aquarium! The females carry green eggs under their tails and release tiny, fully-formed miniature versions of themselves. If you have a few males and females, you will likely end up with baby shrimp with no extra effort.

Amano Shrimp: Breeding them is extremely difficult and rarely achieved by hobbyists. The females carry eggs, but they release microscopic larvae (not shrimplets). These larvae require a transition to full saltwater (brackish water) to develop and then a slow transition back to freshwater. It’s a complex process best left to commercial breeders.

Sustainable and Eco-Friendly Sourcing

As responsible aquarists, it’s worth considering where our shrimp come from. This is a key part of practicing sustainable ghost vs amano shrimp husbandry.

Ghost shrimp are almost always captive-bred in the US, making them a very sustainable and eco-friendly choice. Their ease of breeding means there’s little need to collect them from the wild for the aquarium trade.

Amano shrimp, due to their difficult breeding cycle, are often wild-caught. While collection is generally managed, choosing shrimp from a reputable supplier who prioritizes responsible collection methods is always the best practice. Supporting businesses that are developing captive-breeding programs is a great way to push the hobby in a more sustainable direction.

Frequently Asked Questions About Ghost vs Amano Shrimp

Can Ghost and Amano shrimp live together?

Absolutely! They are excellent tank mates for each other. They occupy slightly different niches, with the Amanos focusing on algae and the Ghosts on leftovers, so they make a fantastic and comprehensive cleaning team.

Which shrimp is better for a nano tank (under 10 gallons)?

For smaller tanks, Ghost shrimp are often a better fit due to their slightly smaller adult size and lower bioload. A small group of 3-5 can live happily in a 5-gallon tank. Amanos are more active and do better with the extra space a 10-gallon tank provides.

Are Amano shrimp worth the higher price?

If your primary goal is to combat stubborn algae like hair algae or BBA, then yes, they are 100% worth it. No other shrimp comes close to their effectiveness. If you just want a fun scavenger to clean up leftover food, the more affordable Ghost shrimp will do the job perfectly.

Why did my Ghost shrimp disappear?

This is a common issue. It could be due to a few things: they are excellent hiders, they may have died and been consumed by other tank mates (they decompose quickly), or they could have been eaten by a fish. Also, remember the Whisker shrimp imposter—if other small creatures are disappearing, you may have a predator in disguise!

Conclusion: The Final Verdict

So, after breaking down the great ghost vs amano shrimp showdown, which one should you choose? The answer isn’t about which shrimp is “better” overall, but which one is better for you and your aquarium’s specific needs.

Choose the Ghost Shrimp if:

  • You’re on a tight budget.
  • Your main goal is to clean up leftover fish food.
  • You’re interested in easily breeding shrimp in your aquarium.
  • You have a smaller nano tank (5-10 gallons).

Choose the Amano Shrimp if:

  • Your primary mission is to destroy algae.
  • You have a planted tank and want to keep it spotless.
  • You aren’t concerned with breeding.
  • You have a tank of 10 gallons or more.

No matter which you pick, you’re adding a fascinating, hardworking creature to your underwater world. They bring life, movement, and cleanliness to any setup. Trust your newfound knowledge, pick the shrimp that fits your goals, and enjoy watching your new cleanup crew get to work. Happy shrimping!
