Ghost Shrimp vs. Amano Shrimp: Which Cleanup Shrimp Is Best?

Ghost Shrimp vs. Amano Shrimp: Which Freshwater Cleanup Shrimp Is Right for Your Tank?

If you're shopping for an algae-eating, scavenging dwarf shrimp, two names dominate the conversation: Ghost Shrimp (Palaemonetes sp.) and Amano Shrimp (Caridina multidentata). Both are inexpensive, peaceful freshwater invertebrates and excellent at cleaning up uneaten food and nuisance algae — but they are very different animals with very different lifespans, appetites, and best-use cases. This guide compares them side-by-side and helps you pick the right shrimp for your community tank, planted aquarium, or breeder setup.

At Tropical Treasures Wyo in Cheyenne, Wyoming, we keep both species in stock and use them in our own display tanks. Below is everything we tell customers when they ask, "Which shrimp should I buy?"

Quick Comparison Chart

Ghost Shrimp: The Affordable All-Rounder

The Ghost Shrimp (Palaemonetes sp.), also called glass shrimp or grass shrimp, is the entry-level invertebrate of the freshwater hobby. Almost completely transparent, they show off their internal organs and the food they've just eaten — kids love them, and they're a perfect "first shrimp" for new aquarists and hobbyists.

Strengths

• Inexpensive — often the cheapest shrimp at any fish store.
• Scavengers — eat leftover flakes, pellets, frozen food, blanched veggies, biofilm, and detritus on the tank bottom.
• Easy to breed in pure freshwater, unlike Amanos.
• Useful as feeders for puffers, larger cichlids, and predatory fish.

Weaknesses

• Shorter lifespan (typically 1–2 years).
• Only moderate algae eaters — they'll nibble aquarium plants and algae but won't out-clean an Amano shrimp.
• Larger specimens may occasionally pick at slow fish, dead tankmates, or each other if underfed.
• Quality varies — many are mass-bred as feeders, so health and color can be hit-or-miss.

Best Tank Setups for Ghost Shrimp

Ghost Shrimp thrive in nano community tanks (5–20 gallons) with peaceful tank mates like Neon Tetras, Pristella Tetras, or Forktail Rainbowfish. Add hides, driftwood, and a sponge filter along with moderate current from power filters to simulate their natural environment and encourage natural ghost shrimp behavior and molting cycles. They'll happily breed without intervention. Avoid keeping them with any cichlid, betta, or fish over 3 inches if you want them to survive long-term.

Amano Shrimp: The Algae-Eating Champion

Named after legendary aquascaper Takashi Amano, the Amano Shrimp (Caridina multidentata) is widely considered the best algae-eating shrimp in the freshwater hobby. They are roughly twice the body mass of a Ghost Shrimp and graze constantly on hair algae, green spot algae, soft film algae, and leftover food on aquarium plants and substrate.

Strengths

• Unmatched algae control — a small group of 5–10 can clear nuisance algae from a planted 20-gallon freshwater aquarium in weeks.
• Long lifespan — 2–3 years, sometimes more, allowing for a stable cleanup crew.
• Very peaceful — safe with any non-aggressive fish, including Otocinclus, small tetras, and rasboras.
• Larger and more visible than Ghost or Neocaridina shrimp — they don't disappear into the scape and their antenna and swimmerets are easily observed.
• Available in color variants: Sun Orange Amano, Giant White Amano, and the classic Yamato Amano.

Weaknesses

• Cannot breed in freshwater. Larvae require a brackish water stage to develop, so a closed-loop colony in a home freshwater aquarium is essentially impossible for the hobbyist.
• More expensive per shrimp than Ghost Shrimp.
• Voracious appetites — once algae is gone, they need supplemental feeding such as sinking wafers, blanched zucchini, or leaf litter.

Best Tank Setups for Amano Shrimp

Amano Shrimp shine in planted aquariums of 10 gallons and up. They pair beautifully with Anubias, Java Fern, and any of our live aquarium plants. Their compatibility with peaceful schooling fish like rasboras, small tetras, Otocinclus catfish, and Corydoras make them excellent tank mates in community setups. Keep them out of tanks with angelfish, larger gouramis, or aggressive fish that can prey on shrimp on sight.

Head-to-Head: Which One Wins?

Best for Algae Control

Winner: Amano Shrimp. Not even close. If your goal is to eliminate hair algae, soft film, and diatoms, six Amanos will do more work than thirty Ghost Shrimp because of their constant grazing behavior across aquarium plants and surfaces.

Best for Beginners

Winner: Ghost Shrimp. They're cheap, forgiving, and a low-risk way to learn shrimp care and observe shrimp molting before investing in Cherry Shrimp or Blue Cherry Shrimp.

Best for Breeding

Winner: Ghost Shrimp. They breed freely in freshwater tanks, with female shrimp carrying baby shrimp (larvae) that develop fully within your home aquarium. Amano larvae require brackish conditions, making them effectively non-breeding in a home tank.

Best for Long-Term Cleanup Crews

Winner: Amano Shrimp. Their longer lifespan and constant algae eating make them a much better investment for established planted tanks with sustained algae control.

Best Looking

Tie / personal preference. Ghost Shrimp look like swimming glass with transparent bodies — fascinating to observe their antenna and swimmerets up close. Amanos have an attractive speckled lateral stripe and a more substantial "shrimp" silhouette. For vibrant colors, explore Cherry or Neocaridina shrimp instead.

Care Requirements Compared

Water Parameters

Both species are remarkably adaptable to typical freshwater aquarium water parameters. Aim for:

• Temperature: 70–78°F
• pH: 6.8–7.8
• GH: 6–12 dGH (Amanos appreciate harder water)
• KH: 2–8 dKH
• Ammonia/Nitrite: 0 ppm — both species are very sensitive to ammonia spikes during cycling.

Feeding

In a mature tank with algae and biofilm, neither shrimp requires daily feeding. Supplement 2–3 times per week with high-quality sinking foods. Good options include algae wafers, shrimp pellets, and blanched zucchini or spinach. Avoid copper-based foods and medications — copper is lethal to all freshwater shrimp.

Tank Size

Ghost Shrimp can live comfortably in tanks as small as 5 gallons. For Amano Shrimp, we recommend a minimum of 10 gallons because of their larger size, more active behavior, and higher appetite. Both species benefit from groups of 5 or more individuals to express natural schooling and scavenging behavior.

Substrate and Decor

Both shrimp thrive in planted, mature tanks featuring driftwood, leaf litter, and dense aquarium plants. Plants like Anubias Nana, mosses, and floating plants provide excellent grazing surfaces and hiding spots after shrimp molt, aiding in their health and stress reduction.

Can You Keep Ghost Shrimp and Amano Shrimp Together?

Yes — they cohabitate without issue in the same freshwater aquarium, since both are peaceful scavengers occupying similar ecological niches. Just remember Amano Shrimp will often out-compete Ghost Shrimp for food, so feed enough to go around. A mixed cleanup crew of 6 Amanos and 6 Ghost Shrimp is a great low-cost setup for a 20-gallon community tank.

Where to Buy Healthy Shrimp

Shrimp quality matters more than price. Mass-bred feeder Ghost Shrimp are often stressed and die within weeks; quarantined, well-fed shrimp from a reputable source last for their full natural lifespan. At Tropical Treasures Wyo we acclimate all incoming shrimp slowly, treat them with shrimp-safe care protocols, and only sell them once they're feeding actively and healthy.

Frequently Asked Questions

Will Amano Shrimp eat all my algae?

They aggressively consume soft film algae, green hair algae, diatoms, and biofilm on aquarium plants and decorations. However, they will not effectively eat black beard algae (BBA), blue-green algae (cyanobacteria), or staghorn algae. For BBA, focus on adjusting CO₂ levels and water flow in your aquarium first.

Are Ghost Shrimp aggressive?

No — but larger, hungry Ghost Shrimp may pick at sick or slow fish, baby shrimp (fry), or each other if food is scarce. Maintaining consistent feeding and good water parameters keeps them peaceful.

How many Amano Shrimp do I need for a 20-gallon tank?

5–8 Amanos is a good starting point for a 20-gallon planted tank. Increase the number if you face a serious algae outbreak.

Do Ghost Shrimp clean tanks?

Yes, but mainly through scavenging leftover food and detritus rather than aggressive algae eating. Think of them as detritus cleaners rather than dedicated algae eaters.

Can shrimp live with bettas?

Sometimes. Some bettas ignore shrimp, while others hunt and eat them. Always provide plenty of aquarium plants and hiding spots, and start with inexpensive Ghost Shrimp to test your betta's temperament before adding pricier Amano or Neocaridina shrimp.

Do Amano Shrimp breed in freshwater?

No. The female releases larvae that must develop in brackish water before returning to freshwater. Hobbyist breeding is theoretically possible but not practical — it's best to buy them instead of trying to breed.

Why did my shrimp die after a water change?

Almost always due to copper, chlorine, or rapid temperature changes. Always use a quality dechlorinator, match the temperature to your tank, and drip-acclimate new shrimp over 1–2 hours to minimize shock.

What's the difference between Amano and Yamato Amano shrimp?

"Yamato" is simply the Japanese name for the same species (Caridina multidentata). They are the same shrimp, sometimes sold under either label depending on the supplier.

Can I keep Amano and Cherry Shrimp together?

Yes. They occupy similar niches and won't interbreed (different genera). Just ensure you feed enough so the larger Amanos don't out-compete the smaller Neocaridina shrimp.
