# Ghost Shrimp Care Guide: The Invisible Cleanup Crew for Your Aquarium

*Palaemonetes paludosus*

Master Ghost Shrimp care with our expert guide. Learn about Palaemonetes paludosus tank requirements, breeding, and how to keep these clear shrimp thriving.

## Species Overview

Ghost shrimp (*Palaemonetes paludosus*) are fully transparent freshwater invertebrates native to the southeastern United States — you can see their digestive tract, organs, and even the tiny eggs in a berried female right through their bodies. That transparency, combined with a $0.25–$1.00 price tag and an appetite for detritus, biofilm, and leftover food, makes them one of the most widely sold aquarium invertebrates in North America.

The catch is that most ghost shrimp are sold as "feeders" — bulk-packed, poorly conditioned, and kept in holding tanks with no intention of long-term survival. A ghost shrimp kept in a properly cycled, stable aquarium can live 1–1.5 years and breed readily. Most "ghost shrimp die within a week" stories trace directly to buying from a feeder tank, not to the species being fragile.

### Identifying *Palaemonetes paludosus* vs. Whisker Shrimp

True ghost shrimp are nearly fully transparent with a small colored dot at the base of the tail and short, proportionate antennae. Their rostrum (the pointed beak between the eyes) is short and slightly upturned. The body is slender, under 1.5 inches, and the legs are clear or faintly banded.

Whisker shrimp (*Macrobrachium* species, sometimes called "freshwater prawns") are frequently mixed into ghost shrimp shipments and are the source of most "my ghost shrimp attacked a fish" stories. Whisker shrimp grow larger (up to 2+ inches), have noticeably longer, heavier front claws, and will pick at small fish and other invertebrates. Look for disproportionately long feelers and heavier front claws — if you see either at the store, the tank is probably mixed. Pick individuals from the far end of the tank that look smallest and slenderest.

If you want a clearly identified, non-aggressive shrimp for a community nano tank, [red cherry shrimp](/species/red-cherry-shrimp) or [amano shrimp](/species/amano-shrimp) are safer bets from a species-ID standpoint.

### Understanding the "Feeder Shrimp" Stigma

Pet stores purchase ghost shrimp as live feeders for puffer fish, aggressive cichlids, and large predatory fish. Because the intended life expectancy is zero, feeder ghost shrimp are kept at high density, fed minimally, and shipped under conditions that would be unacceptable for "display" livestock. The mortality in the holding tank is high — 20–40% losses per week are not unusual — and the survivors are stressed, under-nourished, and carrying latent infections.

This is not an inherent property of the species. Ghost shrimp raised in clean, well-fed, properly managed conditions are genuinely hardy. The stigma comes entirely from the supply chain, not the animal.

### Average Size (1.5") and Lifespan (1 Year)

Males top out around 1 inch; females reach 1.5 inches and are visibly deeper-bodied, especially when carrying eggs. Lifespan is 1–1.5 years under good conditions — shorter than [red cherry shrimp](/species/red-cherry-shrimp) (1–2 years) and much shorter than [amano shrimp](/species/amano-shrimp), which can live 3–5 years. Their shorter lifespan means you should expect occasional natural deaths even in a thriving colony, and a colony's age distribution matters more than any single individual's fate.

## Water Parameters & Tank Requirements

Ghost shrimp occupy one of the widest parameter tolerances of any common aquarium invertebrate. That tolerance is one reason they're sold as feeders — they survive conditions that would kill more delicate species. It does not mean optimal conditions don't matter; they absolutely do for longevity and breeding.

### Ideal Temperature (65°F–80°F) and pH (7.0–8.0)

The natural range of *Palaemonetes paludosus* spans slow-moving ponds, ditches, and rivers throughout Florida, Georgia, and the Carolinas — environments that run warm and moderately hard. Aquarium temperatures of 72–78°F sit in the middle of their comfort zone and support active feeding and breeding. Below 65°F the shrimp become sluggish and stop molting normally; above 82°F dissolved oxygen drops and lifespan shortens measurably.

pH between 7.0 and 8.0 matches their native water. They are not acid-tolerant the way some *Caridina* species are — avoid active aquasoils that buffer pH below 7.0. Stable pH matters more than the exact number in the range; a tank that holds 7.4 without swings will always outperform one that fluctuates between 6.8 and 7.8 daily.

### Minimum Tank Size (5 Gallons) and Filtration Needs

Five gallons is the functional minimum for a small group of 10–15 shrimp. A 10-gallon is a more forgiving setup — more water volume means slower parameter swings, and ghost shrimp are more active and interesting to watch when they have room to spread out.

Sponge filtration is strongly preferred. Like all small invertebrates, ghost shrimp can get pulled into hang-on-back filter intakes, and shrimplets are small enough to pass straight through standard intake strainers. An air-driven sponge filter provides gentle flow, mechanical filtration, and grows biofilm on its surface that shrimp graze on constantly. If you run a hang-on-back for a larger setup (over 20 gallons), fit the intake with a fine foam pre-filter sleeve.

> **Cycle before you stock**
>
> Ghost shrimp are sold as cheap and disposable, so beginners often skip cycling and add them to a new tank. Any detectable ammonia will kill them — and a new tank cycles through an ammonia spike. Add them only after you reach zero ammonia, zero nitrite, and a measurable nitrate reading.

### The Importance of Calcium and GH for Molting

Ghost shrimp molt regularly throughout their lives — juvenile shrimp molt every week or two, adults less frequently. Each molt requires enough dissolved calcium and magnesium (measured as GH, or general hardness) to calcify the new exoskeleton before shedding the old one.

Target GH of 6–10 dGH. Soft water below 4 dGH produces failed molts: shrimp that crack out of their old shell but can't fully exit, or new shells that collapse on the animal. If your tap water is very soft, a small piece of crushed coral in the filter or a shrimp-specific mineral supplement like Salty Shrimp GH/KH+ brings GH into range without dramatically affecting other parameters.

Empty molted shells scattered on the substrate look alarming but are completely normal — ghost shrimp often eat the shed shell to reclaim minerals. Leave it in place for 24 hours before removing.

## Diet & Feeding

Ghost shrimp are opportunistic scavengers that spend most of their waking hours picking at surfaces. They are not active hunters in the way that larger crustaceans are — they graze passively and process what they find.

### Scavenging Habits: Biofilm and Detritus

In a mature planted tank, ghost shrimp get a significant portion of their nutrition from biofilm — the thin microbial layer that coats driftwood, rocks, substrate, and leaves. They also consume soft algae (diatoms, green spot algae film), decaying plant matter, and uneaten fish food that drifts to the substrate. This cleanup role is genuinely useful: a group of 10 ghost shrimp in a community tank measurably reduces the amount of detritus accumulating between gravel vacuums.

They do not eat fish waste. This is a persistent misconception. Fish waste needs to be removed through gravel vacuums and water changes — ghost shrimp will not substitute for that work.

### Supplemental Feeding: Sinking Pellets and Algae Wafers

In a new tank without established biofilm, or in a lightly planted setup, supplemental feeding fills the gap. Break an algae wafer into a quarter-piece and drop it near where the shrimp congregate — they'll find it within minutes. Sinking pellets formulated for shrimp or small bottom dwellers (Hikari Crab Cuisine, Fluval Bug Bites Bottom Feeder) work equally well. Feed every 1–2 days and remove uneaten food after 8–12 hours to prevent ammonia spikes.

Ghost shrimp also accept blanched vegetables: zucchini, spinach, and cucumber all work. Blanch (30 seconds in boiling water), cool completely, cut a small piece, and clip it to the side of the tank or just drop it in. Remove after 12 hours.

### Calcium-Rich Foods for Shell Development

If you notice frequent failed molts or soft shells, supplement with calcium-rich foods in addition to GH management. Cuttlebone — sold in the bird section of any pet store — breaks into small pieces, floats briefly, then sinks. Drop a 1-inch piece in and let it dissolve slowly over 2–3 weeks. Ghost shrimp will graze on it directly.

Kale and spinach are naturally high in calcium and serve double duty as supplemental greens. Shrimp-specific "mineral balls" (montmorillonite clay pellets) also leach calcium and trace minerals continuously.

## Tank Mates & Compatibility

Ghost shrimp sit near the bottom of the freshwater food chain, but their size — up to 1.5 inches — gives them more survival options than tiny [cherry shrimp](/species/red-cherry-shrimp) or [sexy shrimp](/species/sexy-shrimp). They can hold their own against fish that would quickly eat smaller invertebrates.

### Best Community Partners (Nano Fish, Snails)

Small, peaceful nano fish are the best tank mates. Ember tetras, chili rasboras, celestial pearl danios, and small rasboras like harlequins all coexist well with adult ghost shrimp. The shrimp's size — and transparency — makes them less tempting targets than the brightly colored [red cherry shrimp](/species/red-cherry-shrimp).

Otocinclus catfish are the gold standard: strictly algae-eating, small enough to ignore ghost shrimp at every life stage, and compatible with the same water parameters. Nerite snails and mystery snails make excellent cleanup crew partners — snails handle the algae surfaces while ghost shrimp work the substrate.

> **Ghost shrimp larvae are tiny and highly vulnerable**
>
> Adult ghost shrimp may survive with many nano fish, but ghost shrimp larvae are planktonic and microscopic for the first 1–3 weeks of life. Any fish in the tank will eat larvae on sight. For successful breeding, a species-only or heavily planted tank is required during the larval stage.

### Predatory Risks: Why Cichlids and Goldfish are Dangerous

Any fish over 3 inches that isn't a strict herbivore (like otocinclus) will eventually eat ghost shrimp. Cichlids — including "peaceful" dwarf species like German blue rams and apistogrammas — will systematically hunt them. Goldfish are aggressive pursuit predators that will eat anything that fits in their mouth, and ghost shrimp fit easily. Bettas fall into a "caution" category: many bettas ignore ghost shrimp entirely due to their transparency, but aggressive individuals will hunt them relentlessly.

Larger loaches (clown loaches, yo-yo loaches) will eat shrimp at night. Gourami species beyond honey gourami are hit-or-miss. The general rule: if a fish has successfully eaten invertebrates in your tank before, it will do it again.

### Ghost Shrimp Aggression: Can They Live With Cherry Shrimp?

True *Palaemonetes paludosus* are peaceful toward other shrimp — they don't compete aggressively for food or territory. Ghost shrimp and [red cherry shrimp](/species/red-cherry-shrimp) can coexist in the same tank without issues.

The complication is the whisker shrimp ID problem. If your "ghost shrimp" tank has any *Macrobrachium* mixed in, those animals will harass and injure cherry shrimp, small snails, and potentially nano fish. Before mixing shrimp species, spend 10 minutes observing the ghost shrimp tank at the store to check for aggressive claw-display behavior or any animal obviously larger than 1.5 inches.

## Breeding Ghost Shrimp

Ghost shrimp breed in captivity, but they're meaningfully harder to breed through to adulthood than cherry shrimp. The adults are easy — they mate readily in stable conditions. The larval stage is where most breeding attempts fail.

### Identifying Berried Females (Green Eggs)

Female ghost shrimp carry eggs attached to swimmerets (small paddle-like appendages under the abdomen). The eggs are distinctly green — unlike the yellow or brownish eggs of cherry shrimp. A berried female fans her eggs constantly to keep them oxygenated, visible as a rhythmic fluttering of the back half of her body. Clutch size is typically 20–40 eggs.

Females are larger than males with a noticeably deeper abdomen. The green egg mass is visible through the transparent body even before the eggs move to the swimmerets, appearing as a green smudge behind the head in the ovary (saddle). Gravid females are easy to spot — the green color contrasts sharply with the clear body.

### The Larval Stage: Why Ghost Shrimp are Harder to Breed than Cherries

This is the critical difference from cherry shrimp. Cherry shrimp eggs hatch as fully formed miniature shrimplets that immediately start grazing biofilm. Ghost shrimp eggs hatch as free-swimming larvae — planktonic, microscopic, and requiring infusoria or green water (phytoplankton) as their first food for the first 1–3 weeks before they metamorphose into juvenile shrimp.

Any fish or adult shrimp in the tank will consume larvae within hours. Larvae also need gentle, almost imperceptible water movement — even the current from a lightly bubbling sponge filter can prevent them from feeding successfully. Successfully raising ghost shrimp larvae to juvenile stage requires dedication and a separate setup.

### Raising Fry in a Dedicated Nursery Tank

The practical approach: move a berried female to a separate 5-gallon nursery tank the week before hatching. The nursery tank should have no fish, very gentle filtration (an air stone is sufficient for the larval stage — sponge filters create too much turbulence), and infusoria or green water ready as first food.

Infusoria cultures can be started by dropping a lettuce leaf in a jar of tank water and leaving it in indirect sunlight for 3–5 days — the resulting cloudy water is loaded with paramecia and rotifers that larvae consume. Green water from a phytoplankton culture is more reliable but requires more preparation. After 2–3 weeks, when juveniles are visible and large enough to graze substrate, a sponge filter can be introduced and the juveniles can be fed powdered shrimp food or Bacter AE.

## Common Health Issues

Most ghost shrimp health problems are environmental. Test water before diagnosing disease.

### Muscular Necrosis (The "White Body" Disease)

Muscular necrosis is the most feared ghost shrimp disease. Affected shrimp turn milky or opaque white — starting at the tail and spreading forward — rather than the expected transparency. The condition is caused by a bacterial infection that attacks muscle tissue and is usually fatal within days. It can spread to other shrimp in the tank.

There is no reliable treatment. Isolate affected shrimp immediately to a separate container and do not return them to the main tank. Increase water changes (20% over two days) in the main tank and check for elevated nitrates or ammonia that may have stressed the colony and allowed bacterial infection to take hold. Muscular necrosis outbreaks often follow a water quality event — a missed water change, a dead fish decomposing, or a sudden temperature spike.

### Failed Molts and Copper Sensitivity

Failed molts look like ghost shrimp that are stuck halfway out of their old shell, or that seem weak and lethargic immediately after molting. The cause is almost always insufficient GH — the new exoskeleton doesn't harden properly, and the shrimp can't complete the exit from the old one.

> **Copper is lethal to ghost shrimp at trace levels**
>
> Ghost shrimp — like all invertebrates — are acutely sensitive to copper. Concentrations under 0.1 ppm will kill an entire tank of shrimp within days. Common sources: most "ich cure" and "general cure" fish medications contain copper sulfate, many plant fertilizers include trace copper, and older homes with copper plumbing can leach copper into tap water. Always verify "invertebrate safe" on any product before using it in a shrimp tank. Never use fish medication in a shrimp tank without reading the active ingredient list first.

If you suspect copper contamination, perform a 50% water change with conditioned, copper-tested water, add activated carbon or Seachem CupriSorb to the filter, and test copper levels directly with a copper test kit.

### Dealing with Horsehair Worms and Parasites

Horsehair worms (*Gordius* or *Nematomorpha* species) are occasional parasites of ghost shrimp in the wild and, rarely, in aquarium specimens collected from natural sources. An infected shrimp will eventually expel a long, hair-thin worm (sometimes as long as 12 inches) that writhes in the water. The worm is harmless to fish and humans, but the shrimp it exits from typically dies.

Wild-caught ghost shrimp carry higher parasite risk than captive-bred stock. Tank-raised ghost shrimp from reputable sources rarely encounter horsehair worms. There is no treatment for an infected individual — remove and euthanize the shrimp.

Other parasites (vorticella, epistylis) appear as fuzzy white growths on the body or appendages. A mild salt dip (1 tablespoon aquarium salt per cup of tank water, 30–60 seconds) treats surface-level protozoans without harming the shrimp.

## Where to Buy & What to Look For

Where you buy ghost shrimp determines 80% of your outcome. The feeder tank at a chain store is the worst possible source for long-term pets.

### Avoiding "Feeder Grade" Mortality Rates

Feeder tanks are restocked weekly from bulk shipments. Shrimp arrive already stressed from transit, are kept at high density with no concern for water quality, and experience 20–40% mortality as a baseline. The survivors are healthy enough to survive short-term but are carrying stress and sub-clinical infections that manifest as mysterious die-offs in your first week.

If the store sells ghost shrimp exclusively as feeders with a "per cup" pricing model, those are feeder shrimp and they will die at feeder-shrimp rates. Look for stores that stock ghost shrimp as display invertebrates — in a separate, properly cycled tank, with a per-shrimp price above $0.75. These are almost always better stock. Online specialty shrimp vendors also sell display-quality ghost shrimp, though overnight shipping adds stress of its own.

### Signs of a Healthy Specimen at Your LFS

> **LFS Survival Checklist: Ghost Shrimp Edition**
>
> Spend 5 minutes at the tank before buying. Look for these specific signs of health:
>
> - **Actively swimming or grazing** — healthy ghost shrimp are almost constantly in motion
> - **Full transparency** — clear body with visible internal organs; no milky or opaque patches anywhere
> - **Green eggs visible in females** — indicates the colony is reproducing and parameters are stable
> - **Intact antennae and legs** — missing limbs signal chronic stress or aggression
> - **No shrimp sitting motionless on the substrate** — listless shrimp are ill
> - **No white body patches** — muscular necrosis spreads; if one shrimp shows it, avoid the entire tank
> - **Tank has no dead shrimp on the bottom** — a single corpse indicates a poorly managed tank
> - **Store can tell you the water parameters** — GH, temperature, and pH at minimum; if they don't test, don't buy
> - **Shrimp are not visibly crowded** — over 30 shrimp per gallon in a feeder tank is a red flag for stress and disease

Acclimate ghost shrimp with the drip method over 60–90 minutes. Their wide parameter tolerance doesn't eliminate acclimation sensitivity — the shift from store water to your water, especially if GH or pH differs significantly, can trigger a molting crisis in the first 48 hours. See [how to acclimate fish](/guides/how-to-acclimate-fish) for the full drip method walkthrough.

## Frequently Asked Questions

### How long do ghost shrimp live?

Ghost shrimp are short-lived, typically surviving 1 to 1.5 years. Their lifespan is often cut short by poor acclimation or being sold as "feeders." Providing stable water parameters and high-quality food can help them reach their maximum age in a home aquarium.

### Do ghost shrimp eat fish poop?

No, ghost shrimp do not eat fish waste. They are scavengers that eat leftover fish food, algae, biofilm, and decaying plant matter. You must still perform regular gravel vacuums and water changes to remove fish waste from the system.

### Can ghost shrimp live with bettas?

It depends on the betta's temperament. While many bettas ignore ghost shrimp due to their transparency, some aggressive bettas will hunt and eat them. Always provide plenty of hiding places like Java Moss if keeping them together.

### Why did my ghost shrimp turn white?

If a ghost shrimp turns a milky, opaque white, it is likely suffering from muscular necrosis or a failed molt. This is often terminal and contagious. Ensure your water has enough calcium and magnesium (GH) to support healthy shell growth.

### Are ghost shrimp aggressive?

True Palaemonetes paludosus are peaceful. However, they are often misidentified at pet stores and sold alongside "Whisker Shrimp," which look similar but have longer feelers and can be aggressive toward small fish and other shrimp.
