The Cleaner Shrimp is one of the most recognizable and useful invertebrates kept in marine reef aquariums. With its brilliant red-and-white body, extremely long white antennae, and bold habit of climbing directly onto much larger fish, this small crustacean provides some of the most fascinating behavior available to saltwater aquarists.
The species most commonly sold simply as the Cleaner Shrimp is Lysmata amboinensis, also known as the Scarlet Skunk Cleaner Shrimp, Pacific Cleaner Shrimp, White-Striped Cleaner Shrimp, or Skunk Cleaner Shrimp.
In nature, Cleaner Shrimp establish cleaning stations where fish approach and allow the shrimp to remove ectoparasites, damaged tissue, mucus, and other edible material. Some client fish even open their mouths and gill covers so the shrimp can climb partially inside to clean them.
Cleaner Shrimp are generally peaceful, reef safe, and relatively easy to maintain in a stable saltwater aquarium. However, they are still sensitive marine invertebrates. Sudden salinity changes, poor water quality, copper-based medications, and predatory tank mates can quickly cause problems.

🔬 What Is a Cleaner Shrimp?
The name Cleaner Shrimp can refer broadly to several marine shrimp that remove parasites and damaged material from fish.
However, in the aquarium trade, the name most often refers to Lysmata amboinensis.
This species belongs to the family Lysmatidae and is closely related to other popular aquarium shrimp such as:
- Blood Red Fire Shrimp
- Peppermint Shrimp
- Atlantic Cleaner Shrimp
Other unrelated crustaceans, including the Banded Coral Shrimp, may also perform cleaning behavior.
For this reason, it is always worth checking the scientific name when purchasing a shrimp rather than relying entirely on the common name.
🌊 Where Do Cleaner Shrimp Come From?
Lysmata amboinensis is a tropical marine shrimp with a broad Indo-Pacific distribution.
It naturally occurs around:
- Coral reefs
- Reef slopes
- Caves
- Crevices
- Coral heads
- Rocky structures
- Cleaning stations frequented by fish
Rather than wandering randomly across the reef, Cleaner Shrimp may occupy prominent locations where fish learn to approach them for cleaning.
Rock ledges and caves are especially useful because they provide both protection and a convenient place from which the shrimp can advertise its services.
🔴 What Does a Cleaner Shrimp Look Like?
The Scarlet Skunk Cleaner Shrimp has an unmistakable appearance.
Its body is translucent to pale yellowish with:
- Brilliant red bands along the sides
- A prominent white stripe running down the back
- Long white antennae
- Pale walking legs
- Red markings near the tail
- Small clawed appendages used during feeding and cleaning
The shrimp’s antennae can make it appear considerably larger than its actual body.
Adults generally reach around 2–2.5 inches long, excluding the long antennae.
The dramatic red-and-white coloration is not merely decorative. Its conspicuous appearance helps advertise the shrimp’s cleaning role to fish.
🧼 Why Are They Called Cleaner Shrimp?
Cleaner Shrimp earn their name through a remarkable form of cleaning mutualism.
A fish approaches the shrimp and adopts a posture indicating that it wants to be cleaned.
The shrimp then climbs onto the fish and may remove:
- External parasites
- Dead skin
- Damaged tissue
- Excess mucus
- Other edible material
Both animals benefit.
The fish receives cleaning services, while the shrimp gains a meal.
This relationship can involve fish dramatically larger than the shrimp—including predators that might ordinarily consider a small crustacean food.
🚏 What Is a Cleaning Station?
A cleaning station is a location where cleaner organisms regularly provide services to visiting fish.
In the aquarium, a Cleaner Shrimp may choose:
- A rock ledge
- A cave entrance
- A coral structure
- An overhang
- A prominent section of live rock
The shrimp may stand there while waving its long white antennae.
Fish that recognize the signal can approach and remain relatively still.
Some may even:
- Tilt their bodies
- Spread their fins
- Open their mouths
- Open their gill covers
Watching a large reef fish calmly allow a tiny shrimp to walk across its face can be one of the most memorable behaviors in a marine aquarium.
🐠 Do Cleaner Shrimp Really Remove Parasites?
Yes.
Scientific studies have documented Lysmata amboinensis removing ectoparasites from fish.
Research has also shown that Cleaner Shrimp can consume certain parasite eggs and free-swimming stages from their environment.
However, this does not mean adding a Cleaner Shrimp cures an aquarium disease outbreak.
A Cleaner Shrimp should not replace:
- Quarantine
- Proper diagnosis
- Appropriate disease treatment
- Good water quality
- Biosecurity
Marine ich, velvet, and other serious diseases require appropriate management.
Think of cleaning behavior as a fascinating ecological service rather than a guaranteed medical treatment for aquarium fish.
🏡 Cleaner Shrimp Tank Size
A 20-gallon aquarium or larger is a good practical starting point for one Cleaner Shrimp.
The shrimp itself is small, but stable water conditions become easier to maintain as aquarium volume increases.
A suitable aquarium should provide:
- Live rock
- Caves
- Overhangs
- Shaded retreats
- Open areas for cleaning behavior
- Stable salinity
- Good filtration
Cleaner Shrimp can also thrive in considerably larger reef aquariums.
In fact, large community reefs provide more opportunities for natural interactions with fish.
🪨 Setting Up a Cleaner Shrimp Aquarium
Cleaner Shrimp appreciate complex rockwork.
Provide:
- Live rock
- Caves
- Crevices
- Overhangs
- Shaded ledges
- Secure hiding places
A shrimp may select one particular location as its preferred home.
It should always have somewhere to retreat after molting because freshly molted shrimp are temporarily soft and vulnerable.
Avoid creating an aquarium so barren that the shrimp is continuously exposed.
A secure shrimp is usually more likely to become confident and visible.
💧 Cleaner Shrimp Water Parameters
Cleaner Shrimp thrive in stable reef-quality seawater.
A useful general range is:
- Temperature: 72–79°F
- pH: 8.1–8.4
- Specific gravity: 1.023–1.026
- Ammonia: 0 ppm
- Nitrite: 0 ppm
- Nitrate: Keep appropriately low
For a coral reef aquarium, specific gravity around 1.025–1.026 closely approximates natural tropical seawater.
Consistency matters enormously.
Shrimp generally tolerate sudden changes in salinity and other parameters less effectively than many hardy marine fish.
🧪 Why Stable Salinity Matters
Marine invertebrates regulate water and salts differently from fish and can be particularly sensitive to rapid changes in salinity.
Problems can occur after:
- Large water changes with mismatched salinity
- Rapid evaporation
- Incorrect top-off practices
- Poor acclimation
- Sudden temperature changes
Evaporated water should normally be replaced with freshwater, not additional saltwater, because salt remains behind as water evaporates.
An automatic top-off system can be particularly useful in reef aquariums where maintaining stable salinity is important.
💧 How to Acclimate a Cleaner Shrimp
Cleaner Shrimp deserve careful acclimation.
Before introduction, compare the aquarium water with the water in the transport bag.
Pay particular attention to:
- Temperature
- Salinity
- pH
A gradual acclimation is preferable when the differences are significant.
Do not leave a newly purchased shrimp sitting indefinitely in deteriorating shipping water, however. The goal is a controlled transition—not an unnecessarily prolonged one.
Once introduced, the shrimp may immediately hide.
This is normal.
Give it time to explore the aquarium and select a secure territory.
🪸 Are Cleaner Shrimp Reef Safe?
Yes.
Lysmata amboinensis is considered an excellent reef-safe shrimp.
It generally does not eat healthy:
- SPS corals
- LPS corals
- Soft corals
- Zoanthids
- Clams
- Anemones
It may walk across corals while exploring the aquarium, but this ordinarily causes no significant damage.
Cleaner Shrimp are consequently among the most popular ornamental crustaceans for mixed reef tanks.
🍤 Why Is My Cleaner Shrimp Stealing Food From Corals?
Although Cleaner Shrimp usually leave corals alone, they are enthusiastic scavengers.
If you place a juicy piece of food directly onto an LPS coral, anemone, or other slow-feeding animal, the shrimp may rush over and steal it.
This can be frustrating during target feeding.
A simple solution is to feed the shrimp first.
Give it an appropriate piece of food, then target-feed the coral while the shrimp is occupied elsewhere.
This behavior is opportunistic feeding—not coral predation.
🍽️ What Do Cleaner Shrimp Eat?
Cleaner Shrimp are omnivorous scavengers.
In nature, they consume material obtained during cleaning interactions as well as other available foods.
In the aquarium, they may eat:
- Fish parasites
- Dead tissue
- Mucus
- Leftover fish food
- Mysis shrimp
- Brine shrimp
- Small pellets
- Marine flakes
- Chopped shrimp
- Chopped clam
- Fish eggs
- Other appropriately sized marine foods
Do not assume that fish-cleaning behavior supplies all of their nutrition.
A Cleaner Shrimp kept in an aquarium with few client fish still requires food.
🍤 Should You Feed Cleaner Shrimp Directly?
Usually, yes.
Cleaner Shrimp often collect plenty of food during ordinary fish feeding, but direct supplemental feeding can be helpful.
Offer small portions of:
- Mysis shrimp
- Marine pellets
- Chopped seafood
- Other quality marine foods
Once or several times per week may be sufficient when the shrimp is already eating abundant leftovers during ordinary feeding.
Avoid excessive food.
A shrimp does not need a large chunk of seafood every day.
🧹 Are Cleaner Shrimp Part of the Cleanup Crew?
They can contribute to general scavenging, but their role is somewhat different from dedicated algae grazers and detritivores.
Cleaner Shrimp may eat:
- Leftover food
- Small pieces of organic material
- Dead tissue
- Certain parasites
However, they are not major algae eaters.
They will not replace:
- Snails
- Herbivorous fish
- Appropriate nutrient management
- Aquarium maintenance
Buy a Cleaner Shrimp because you want the animal and its behavior—not simply as equipment for cleaning the tank.
🦐 Can You Keep One Cleaner Shrimp?
Yes.
A single Cleaner Shrimp can live successfully in a marine aquarium.
It does not need a companion in order to survive.
One shrimp may still establish a cleaning station and interact regularly with aquarium fish.
For smaller reef aquariums, keeping one may be the simplest arrangement.
🦐🦐 Can Cleaner Shrimp Be Kept in Pairs?
Yes.
Cleaner Shrimp naturally occur in pairs, and a compatible pair can work very well in an aquarium.
Two mature shrimp may also reproduce repeatedly.
There is no need to purchase one “male” and one “female” because their reproductive biology is considerably more unusual than that.
Pairs are generally a safer social arrangement than attempting to crowd many Cleaner Shrimp together.
⚠️ Can You Keep a Group of Cleaner Shrimp?
Use caution.
Although some aquarium sources describe Cleaner Shrimp as suitable for groups, behavioral research has shown that Lysmata amboinensis naturally tends toward pair living.
Experimental groups larger than pairs developed aggression, with numbers eventually being reduced toward pairs.
For this reason, keeping:
- One Cleaner Shrimp
- One established pair
is a safer general recommendation than placing many adults into a confined aquarium.
Very large systems may provide different possibilities, but extra individuals should not automatically be assumed to coexist peacefully.
🧬 Male vs. Female Cleaner Shrimp
Cleaner Shrimp have an unusual reproductive system known as protandric simultaneous hermaphroditism.
Young individuals first mature functionally as males.
As they grow, they transition into simultaneous hermaphrodites capable of functioning reproductively as both males and females.
This means mature individuals can:
- Produce sperm
- Produce eggs
- Mate with another mature Cleaner Shrimp
They do not normally fertilize themselves.
Two mature compatible Cleaner Shrimp can therefore form a reproductive pair without the aquarist having to identify separate sexes.
🥚 Why Does My Cleaner Shrimp Have Green Eggs?
A Cleaner Shrimp carrying a mass of eggs beneath its abdomen is displaying normal reproductive behavior.
The eggs may initially appear:
- Green
- Greenish yellow
- Brownish
As development continues, their appearance changes and tiny eyes may eventually become visible.
The eggs are held beneath the abdomen among the swimming appendages.
A healthy pair may produce egg clutches repeatedly.
Unfortunately, getting eggs is much easier than successfully raising the larvae.
🐣 Breeding Cleaner Shrimp
Cleaner Shrimp breed readily under suitable aquarium conditions.
A reproductive cycle is closely connected with molting.
After one mature shrimp molts, mating can occur while its new shell is still soft.
The fertilized eggs are then carried beneath the abdomen until they hatch.
With a healthy pair, the two individuals can alternate reproductive roles over successive cycles.
This is one of the most interesting reproductive systems among commonly kept marine invertebrates.
🍼 Why Is Raising Cleaner Shrimp Larvae Difficult?
Once the eggs hatch, the young do not emerge as miniature versions of the adults.
They enter a long planktonic larval phase.
The tiny larvae drift through the water and require:
- Extremely small live foods
- Carefully controlled water movement
- Specialized larval-rearing tanks
- Excellent water quality
- Repeated feeding
- Protection from filtration equipment
Suitable foods during larval culture can include appropriately sized Artemia and other cultured planktonic foods as development progresses.
Larvae pass through numerous developmental stages before eventually becoming juvenile shrimp.
This makes captive propagation substantially more demanding than breeding many freshwater shrimp.
🧼 Do Cleaner Shrimp Clean Every Fish?
No.
Whether cleaning occurs depends on both the shrimp and the fish.
Some aquarium fish actively seek out cleaning services.
Others may:
- Ignore the shrimp
- Refuse to hold still
- Frighten the shrimp
- Attempt to eat it
Cleaner Shrimp have even been shown to adjust their behavior depending on whether a potential client appears predatory.
Large dangerous clients may trigger more cautious signaling behavior.
Cleaning relationships are therefore much more complex than simply placing a shrimp next to any fish.
🐠 Best Cleaner Shrimp Tank Mates
Cleaner Shrimp are compatible with many peaceful reef fish.
Good potential companions include:
- Clownfish
- Blue Chromis
- Anthias
- Goby Fish
- Bicolor Blenny
- Butterflyfish
- Surgeonfish
- Peaceful angelfish
- Cardinalfish
- Many peaceful wrasses
Larger reef fish may be especially interesting because they sometimes become enthusiastic clients at the shrimp’s cleaning station.
Always evaluate the feeding behavior of the exact species.
⚠️ Cleaner Shrimp Tank Mates to Avoid
Avoid animals naturally inclined to eat crustaceans.
Risky companions can include:
- Lionfish
- Triggerfish
- Hawkfish
- Groupers
- Large predatory wrasses
- Large predatory puffers
- Certain aggressive crabs
A predator may occasionally tolerate a Cleaner Shrimp because it recognizes the cleaning relationship.
However, that is not a guarantee of safety.
A fish capable of swallowing the shrimp should always be considered a risk.
🦁 Can Cleaner Shrimp Live With Lionfish?
This is risky.
In nature, Cleaner Shrimp can interact with predatory client fishes, and some predators appear to recognize cleaners rather than immediately eating them.
However, Lionfish naturally consume shrimp and other crustaceans.
An aquarium provides far less room for the shrimp to escape.
A Cleaner Shrimp may survive with an individual lionfish for some time—or it may eventually become dinner.
If keeping the shrimp alive is a priority, the combination is not recommended.
🐡 Can Cleaner Shrimp Live With Pufferfish?
Generally, this is another high-risk combination.
Many marine puffers are powerful crustacean predators.
A Cleaner Shrimp’s ecological role does not guarantee protection in an aquarium.
The same caution applies to triggerfish and many large wrasses.
🐠 Do Fish Hurt Cleaner Shrimp During Cleaning?
Most cooperative client fish remain remarkably still while being cleaned.
The interaction can even involve the shrimp entering a fish’s mouth.
However, predators occasionally “cheat” and consume cleaners.
Cleaner Shrimp appear capable of recognizing danger and modifying their behavior toward predatory clients.
This makes cleaning stations an especially fascinating example of communication between very different animals.
🩻 Will Cleaner Shrimp Cure Marine Ich?
No.
A Cleaner Shrimp may remove some external organisms from fish, but it should not be considered a cure for marine ich.
The parasite responsible for marine ich has life stages that occur:
- On the fish
- In the environment
- Away from the fish
A shrimp cannot reliably eliminate the complete infection from an aquarium.
Similarly, adding Cleaner Shrimp is not an adequate treatment for marine velvet or other serious parasitic diseases.
Use appropriate quarantine and disease-management procedures instead.
☠️ Cleaner Shrimp and Copper
Do not expose Cleaner Shrimp to copper-based aquarium medications.
Copper treatments used for marine fish diseases can be toxic to shrimp and other invertebrates.
Never treat an entire reef display containing Cleaner Shrimp with copper.
Fish requiring copper treatment should be moved to an appropriate separate quarantine or hospital aquarium.
Be cautious with any medication labeled unsafe for:
- Shrimp
- Crabs
- Snails
- Corals
- Other invertebrates
Always read the manufacturer’s instructions before using medication in a marine aquarium.
🧴 Are Cleaner Shrimp Sensitive to Medications?
Yes.
Many fish medications are not safe for marine invertebrates.
Cleaner Shrimp may be harmed by treatments containing or involving:
- Copper
- Certain pesticides
- Other invertebrate-toxic compounds
Reef display aquariums generally should not be used as hospital tanks.
Separating disease treatment from the display aquarium protects corals, shrimp, snails, biological filtration, and other sensitive organisms.
🦴 Why Do Cleaner Shrimp Molt?
Like all crustaceans, Cleaner Shrimp have an external skeleton that cannot simply expand continuously as the animal grows.
They therefore undergo molting.
During a molt:
- The old exoskeleton is shed.
- The shrimp emerges with a soft new shell.
- The new exoskeleton gradually hardens.
- The shrimp grows between molts.
Molting is normal and continues throughout life.
Young growing shrimp may molt more frequently than older adults.
😱 Is My Cleaner Shrimp Dead or Did It Molt?
A discarded shrimp exoskeleton can look alarmingly like a dead animal.
The molt may include:
- Legs
- Antennae
- Body shell
- Tail
- An apparently complete shrimp shape
Before assuming your shrimp has died, look for the actual animal hiding elsewhere.
A freshly molted shrimp often remains concealed while its new exoskeleton hardens.
The empty shell usually looks translucent and hollow.
🪨 Should You Remove a Cleaner Shrimp Molt?
You do not necessarily have to remove it immediately.
Shrimp and other aquarium scavengers may consume portions of the old exoskeleton and recycle some of its minerals.
However, removing it is also reasonable if:
- It becomes trapped somewhere problematic
- It remains uneaten
- The aquarium is extremely small
- You simply prefer to remove visible debris
The appearance of a normal molt is generally a sign of growth rather than a problem.
🧪 Do Cleaner Shrimp Need Iodine Supplements?
Cleaner Shrimp need appropriate trace elements to maintain normal biological functions, but routine blind iodine dosing is not automatically necessary.
A properly maintained reef aquarium using quality salt mix and regular water changes normally receives a broad mixture of trace elements.
Adding iodine without testing or understanding the aquarium’s needs can create unnecessary risk.
The more important priorities for successful molting are:
- Stable salinity
- Good nutrition
- Proper seawater chemistry
- Low stress
- Good water quality
Avoid trying to force molting through supplementation.
🌙 Why Is My Cleaner Shrimp Hiding?
Hiding can occur for several normal reasons.
A Cleaner Shrimp may disappear because it:
- Recently molted
- Is acclimating to a new aquarium
- Has been frightened
- Is avoiding a predatory tank mate
- Is carrying eggs
- Has found a preferred cave
A newly molted shrimp is particularly vulnerable and may remain hidden until its exoskeleton hardens.
Persistent hiding combined with poor feeding or abnormal behavior warrants closer investigation.
🩺 Signs of a Healthy Cleaner Shrimp
A healthy Cleaner Shrimp should generally have:
- Intact antennae
- Normal walking behavior
- Strong feeding response
- Bright coloration
- Clear body tissue
- Regular exploration of rockwork
- Normal molting
- Active cleaning behavior when suitable fish are present
Do not panic over an occasional missing antenna or limb.
Crustaceans can regenerate lost appendages over successive molts.
More serious warning signs include:
- Persistent inability to stand
- Failure to eat
- Uncoordinated movement
- Repeated unsuccessful molts
- Sudden death after a salinity change
🏪 Choosing a Healthy Cleaner Shrimp
At the aquarium store, look for an individual that:
- Is standing normally
- Responds to movement
- Has good coloration
- Moves its antennae
- Shows interest in food
- Has no obvious severe injuries
Ask how long the shrimp has been in the store.
A specimen that has already acclimated successfully and is feeding can sometimes be a safer purchase than one that arrived only hours earlier.
Also ask for the exact salinity of the store aquarium if possible so you know whether your display differs substantially.
🧹 Cleaner Shrimp vs. Peppermint Shrimp
Cleaner Shrimp and Peppermint Shrimp both belong to the genus Lysmata, but they have noticeably different aquarium roles.
Cleaner Shrimp
- Brilliant red and white coloration
- Extremely long white antennae
- Famous for cleaning fish
- Highly visible
- Frequently establishes cleaning stations
- Usually more expensive
Peppermint Shrimp
- More translucent body
- Red striping
- More secretive
- Often kept for scavenging
- Certain species may consume Aiptasia anemones
Do not assume that every red-striped Lysmata shrimp will perform the same role.
🔥 Cleaner Shrimp vs. Fire Shrimp
The Blood Red Fire Shrimp (Lysmata debelius) is another spectacular member of the genus.
Fire Shrimp generally have:
- Deep red bodies
- White spots
- White antennae
- More secretive behavior
They can perform cleaning behavior but are often less continuously visible than Lysmata amboinensis.
A Cleaner Shrimp is usually the better choice if observing active cleaning stations is the main goal.
🌎 Pacific vs. Atlantic Cleaner Shrimp
The familiar Pacific Cleaner Shrimp is Lysmata amboinensis.
The Atlantic has a very similar species, Lysmata grabhami, commonly called the Atlantic Cleaner Shrimp or Red-Backed Cleaner Shrimp.
The two look remarkably similar but are distinct species.
Modern taxonomy recognizes both separately.
This is another reason that scientific names are useful when purchasing marine livestock.
❤️ Cleaner Shrimp Lifespan
Cleaner Shrimp can live for several years in well-maintained reef aquariums.
Exact lifespan varies with:
- Source
- Age at purchase
- Water quality
- Salinity stability
- Nutrition
- Predation risk
- Successful molting
A healthy shrimp that survives acclimation and is protected from predators can become a long-term member of the aquarium.
✅ Are Cleaner Shrimp Good for Beginners?
Yes—with one qualification.
Cleaner Shrimp are relatively straightforward once placed in a mature, stable marine aquarium.
They:
- Eat readily
- Remain relatively small
- Are reef safe
- Are peaceful
- Need no specialized lighting
- Adapt well to many reef communities
The main beginner risks are:
- Poor acclimation
- Unstable salinity
- Copper exposure
- Predatory tank mates
- Adding the shrimp to an immature aquarium
Someone comfortable maintaining stable saltwater parameters should find Cleaner Shrimp relatively easy to keep.
❤️ Is a Cleaner Shrimp Right for Your Aquarium?
The Cleaner Shrimp is one of the best marine invertebrates for aquarists who want an animal that is both beautiful and behaviorally fascinating.
It is particularly well suited to:
- Reef aquariums
- Peaceful marine communities
- Tanks containing larger cooperative reef fish
- Aquarists interested in natural symbiotic behavior
- Mixed coral displays
- Established saltwater aquariums with stable parameters
Its biggest limitations are vulnerability to predators and sensitivity to inappropriate medications and sudden water changes.
Provide stable reef-quality seawater, plenty of rockwork, appropriate supplemental foods, and compatible tank mates, and Lysmata amboinensis can become much more than another member of the cleanup crew.
Watching a fish voluntarily approach the shrimp, hold perfectly still, and allow it to climb across its body—and occasionally directly into its mouth—is a remarkable glimpse of natural reef behavior that can occur right inside the home aquarium.
❓ Frequently Asked Questions
How big do Cleaner Shrimp get?
Scarlet Skunk Cleaner Shrimp generally reach approximately 2–2.5 inches long, excluding their long antennae.
What size tank does a Cleaner Shrimp need?
A 20-gallon aquarium or larger is a good practical starting point.
Are Cleaner Shrimp reef safe?
Yes. They generally coexist safely with corals, clams, anemones, and other typical reef organisms.
Do Cleaner Shrimp really clean fish?
Yes. They remove parasites, damaged tissue, mucus, and other material from willing client fish.
Do Cleaner Shrimp cure marine ich?
No. Cleaning behavior should not be treated as a reliable cure for marine ich, velvet, or other serious aquarium diseases.
What do Cleaner Shrimp eat?
They are omnivorous scavengers that eat parasite material, leftover foods, mysis shrimp, pellets, chopped seafood, and other appropriately sized marine foods.
Do Cleaner Shrimp need to be fed?
Yes. Do not assume they receive enough nutrition simply by cleaning fish.
Can you keep one Cleaner Shrimp?
Yes. One can live successfully on its own.
Can Cleaner Shrimp live in pairs?
Yes. Pairs are particularly natural for Lysmata amboinensis and may breed regularly.
Can you keep several Cleaner Shrimp together?
Use caution. Research on Lysmata amboinensis indicates strong pair-living behavior and aggression toward excess individuals in groups. One shrimp or a compatible pair is the safer general arrangement.
How can you tell a male Cleaner Shrimp from a female?
Mature Cleaner Shrimp are protandric simultaneous hermaphrodites. They begin life functioning as males and later develop the ability to function reproductively as both sexes.
Why does my Cleaner Shrimp have eggs?
A mature shrimp in a compatible pair can carry fertilized eggs underneath its abdomen. This is normal reproductive behavior.
Can Cleaner Shrimp breed in aquariums?
Yes. Adults breed readily, but raising the planktonic larvae through development is much more difficult.
Why did I find what looks like a dead Cleaner Shrimp?
It may simply be a discarded molt. Look carefully for the actual shrimp hiding in the rockwork before assuming it has died.
Are Cleaner Shrimp sensitive to copper?
Yes. Copper-based fish medications can be toxic to Cleaner Shrimp and other marine invertebrates.
Can Cleaner Shrimp live with Lionfish?
It is risky. Although some predatory fish recognize cleaners, Lionfish naturally eat crustaceans and may eventually consume the shrimp.
Do Cleaner Shrimp eat algae?
They may pick at various organic materials, but they are not effective dedicated algae-control animals.
Will Cleaner Shrimp steal food from corals?
They can. Feeding the shrimp before target-feeding corals or anemones can help keep it occupied.
