# Ghost Shrimp Care Guide: Tank Setup, Feeding, Tank Mates & Breeding

Everything you need to keep ghost shrimp thriving — tank size, water parameters, compatible tank mates, feeding tips, and how to breed them successfully.

Ghost shrimp (*Palaemonetes paludosus*) are one of the most affordable and widely available freshwater invertebrates in the hobby. Their transparent bodies, constant foraging behavior, and rock-bottom price tag make them a popular choice for beginners, cleanup crews, and breeding projects alike. This guide covers everything you need to keep ghost shrimp healthy and breeding — from tank setup and water parameters through feeding, compatible tank mates, and the larval rearing process that most other guides skip entirely.

## What Are Ghost Shrimp?

Ghost shrimp are small, nearly transparent freshwater shrimp native to the lakes, streams, and marshes of the eastern United States. They are sold in almost every pet store in the country — often as feeder shrimp — but they deserve better than that reputation. In the right setup, they are fascinating to watch, surprisingly active, and practically maintenance-free.

### Species Overview and Scientific Name

The ghost shrimp you find in freshwater aquarium shops almost always belong to the species *Palaemonetes paludosus*, a member of the family Palaemonidae. They are sometimes sold under the broader genus label *Palaemonetes* sp. because shipments from wholesalers occasionally include mixed species that are visually indistinguishable at point of sale. Their native range spans freshwater habitats across the eastern and central United States, from the Great Lakes basin south through the Gulf states (per American Currents, North American Native Fishes Association).

### Why Hobbyists Love Them

Three things drive the popularity of ghost shrimp. First, price: they typically cost $0.25-$0.50 each, making them the cheapest invertebrate in the hobby. Second, behavior: they spend the entire day scavenging, climbing plants, and investigating every surface in the tank. Third, their transparent bodies let you watch their internal organs work in real time — you can see the heart beating, food moving through the digestive tract, and eggs developing in gravid females. That alone makes them a hit with kids and biology-minded hobbyists.

### Ghost Shrimp vs. Glass Shrimp vs. Grass Shrimp — Same or Different?

These three names get used interchangeably in pet stores, but they can refer to different species. "Ghost shrimp" and "glass shrimp" usually mean *Palaemonetes paludosus* in the freshwater hobby. "Grass shrimp" often refers to *Palaemonetes pugio* or *Palaemonetes vulgaris*, which are brackish-water or saltwater species collected from coastal estuaries. The care difference matters: true freshwater ghost shrimp thrive in pure freshwater, while grass shrimp may decline without some salinity. If your "ghost shrimp" die quickly despite good water parameters, you may have received misidentified grass shrimp. Buy from a [local fish store](/near-me) where staff can confirm the species rather than grabbing a bag from a feeder tank at a chain store.

## Ghost Shrimp Tank Requirements

Ghost shrimp are hardy, but a proper setup prevents the premature deaths that give them an undeserved reputation as disposable animals.

### Minimum Tank Size and Stocking Density

A 10-gallon tank is the practical minimum. Ghost shrimp produce minimal bioload individually, but the water volume in smaller tanks swings too quickly in temperature and chemistry for consistent shrimp health. Stock at 3-4 shrimp per gallon in a species-only tank, or 1-2 per gallon in a community setup. A 10-gallon comfortably supports 20-30 ghost shrimp with adequate filtration.

### Substrate Choice: Why Fine Sand Beats Gravel

Fine sand is the best substrate for ghost shrimp. They spend hours sifting through it for food particles, and their small legs navigate sand easily. Coarse gravel traps uneaten food and waste in gaps the shrimp cannot reach, leading to ammonia spikes in the substrate layer. If you prefer a planted tank, use our tool for [calculating how deep to lay your sand substrate](/tools/substrate-depth) to balance plant root health with shrimp-safe substrate depth.

### Water Parameters

Stable water chemistry keeps ghost shrimp alive far more reliably than hitting exact numbers. Here are the target ranges.

### Ghost Shrimp Water Parameters

| Parameter               | Target            | Notes                                             |
| ----------------------- | ----------------- | ------------------------------------------------- |
| Temperature             | 65-80 F (18-27 C) | Tolerant range, but avoid swings over 2 F per day |
| pH                      | 7.0-8.0           | Slightly alkaline preferred; avoid below 6.5      |
| GH (General Hardness)   | 5-10 dGH          | Calcium and magnesium support healthy molts       |
| KH (Carbonate Hardness) | 3-8 dKH           | Higher KH buffers pH and prevents crashes         |
| Ammonia                 | 0 ppm             | Any detectable level is toxic                     |
| Nitrite                 | 0 ppm             | Lethal to invertebrates at any concentration      |
| Nitrate                 | Under 20 ppm      | Controlled with weekly 15-20% water changes       |

> **Don't skip the nitrogen cycle**
>
> Ghost shrimp are cheap, so many beginners toss them into uncycled tanks as "test animals." This kills them — and then the hobbyist concludes ghost shrimp are fragile. They are not. They simply cannot survive ammonia and nitrite any better than your fish can. Cycle the tank fully (0 ammonia, 0 nitrite for at least one week) before adding shrimp. A fishless cycle takes 4-6 weeks.

### Filtration: Sponge Filters vs. HOB

Sponge filters are the best choice for any shrimp tank. They provide biological filtration, create gentle water flow, and pose zero risk to shrimplets. The sponge surface also grows biofilm that ghost shrimp graze on throughout the day.

Hang-on-back (HOB) filters and canister filters work, but you must cover the intake with a fine sponge pre-filter. Without one, baby shrimp and even small adults get pulled into the intake and killed. A stainless steel mesh or foam pre-filter sponge is a non-negotiable accessory for any power filter in a shrimp tank.

> **Warning**
>
> Running a HOB or canister filter without an intake guard is the fastest way to lose shrimplets. Cover every intake with a sponge pre-filter — no exceptions.

## Ghost Shrimp Diet and Feeding

Ghost shrimp are the definition of low-maintenance eaters. They are opportunistic omnivores that scavenge constantly, but targeted feeding keeps them healthy and supports breeding.

### What They Eat in the Wild vs. Captivity

In their native waterways, *Palaemonetes paludosus* feed on detritus, decaying plant matter, biofilm, algae, and tiny invertebrates. In captivity, they fill the same role: cleaning up uneaten fish food, grazing on biofilm, and picking through substrate. A mature, planted tank provides a significant portion of their diet without any supplemental feeding.

### Best Foods: Sinking Pellets, Algae Wafers, and Blanched Vegetables

Supplement with sinking pellets or algae wafers 2-3 times per week. Shrimp-specific foods from Hikari, GlasGarten, or Shrimp King provide balanced nutrition with the minerals needed for healthy molting. Blanched zucchini, spinach, and cucumber are excellent vegetable supplements — blanch for 30-60 seconds, cool completely, and drop a small piece into the tank. Remove uneaten portions after 12-24 hours.

### Are Ghost Shrimp Effective Algae Eaters?

> **Myth check: ghost shrimp are NOT reliable algae eaters**
>
> Ghost shrimp nibble soft algae opportunistically, but they will not control an algae outbreak. If algae management is your goal, nerite snails or amano shrimp (*Caridina multidentata*) are far more effective. Ghost shrimp are scavengers first and algae grazers a distant second.

## Compatible Tank Mates

Ghost shrimp are prey animals. Tank mate selection is about finding species that will leave them alone, not species that "might" coexist.

### Safe Companions

Small, peaceful fish with tiny mouths are the safest options. Ember tetras, chili rasboras (*Boraras brigittae*), celestial pearl danios, otocinclus catfish, and dwarf corydoras (*Corydoras pygmaeus*, *Corydoras habrosus*) all coexist well with ghost shrimp. Nerite snails are ideal invertebrate companions — they eat algae, cannot breed in freshwater, and ignore shrimp completely. Amano shrimp and mystery snails also work without conflict.

### Fish to Avoid

Bettas, cichlids of any kind (including rams and apistos), gouramis larger than honeys, loaches, and large tetras will actively hunt ghost shrimp. Angelfish are a common mistake — they look peaceful but will eat every shrimp in the tank within days. Crayfish and freshwater crabs are also predatory toward shrimp.

| Category        | Safe Tank Mates                                      | Risky / Avoid                                                 |
| --------------- | ---------------------------------------------------- | ------------------------------------------------------------- |
| Small fish      | Ember tetras, chili rasboras, celestial pearl danios | Bettas, neon tetras (borderline), guppies (some chase shrimp) |
| Bottom dwellers | Otocinclus, pygmy corydoras, dwarf corydoras         | Loaches, larger corydoras species                             |
| Cichlids        | None safe                                            | All cichlids — rams, apistos, angelfish, oscars               |
| Other inverts   | Nerite snails, amano shrimp, mystery snails          | Crayfish, crabs, assassin snails                              |

*Ghost shrimp compatibility — when in doubt, keep them in a species-only tank.*

### Keeping Ghost Shrimp in a Species-Only Tank

A species-only setup eliminates predation risk entirely and maximizes breeding success. Ghost shrimp are active and entertaining enough to carry a tank on their own, especially in a planted layout with driftwood and moss. The colony will grow rapidly without predation pressure, and you can observe natural behaviors — territorial scuffles, mating dances, and larval development — that you would miss in a community tank.

## Ghost Shrimp Breeding

Breeding ghost shrimp is straightforward in terms of getting eggs. The hard part — and the part most guides skip — is keeping the larvae alive after hatching.

### Sexing Ghost Shrimp

Females are noticeably larger than males at maturity (around 1.5 inches vs. 1 inch). Gravid females develop a visible green egg saddle along the underside of the abdomen. Males are slimmer with a flatter underside. Sexing is unreliable in juveniles; wait until shrimp reach adult size for accurate identification.

### Breeding Setup and Triggering Spawning

Ghost shrimp breed readily in stable conditions without special intervention. Consistent parameters within the ranges above, a photoperiod of 8-10 hours, and a varied diet are sufficient. A partial water change (10-15%) with slightly cooler, dechlorinated water often triggers molting in females, followed by the release of pheromones that initiate mating. After mating, the female carries fertilized eggs on her swimmerets for 2-3 weeks.

### Raising Larvae: The Step Most Guides Skip

This is where ghost shrimp breeding differs fundamentally from cherry shrimp or other *Neocaridina* species. Cherry shrimp hatch as fully formed miniatures that eat the same foods as adults. Ghost shrimp hatch as free-swimming planktonic larvae that cannot eat adult foods and require microscopic nutrition for the first 5-7 days of life.

> **First foods for ghost shrimp larvae**
>
> Newly hatched larvae need infusoria, green water (free-floating algae), or commercially prepared powdered fry food such as Hikari First Bites. Start culturing green water or infusoria at least one week before the female is due to release larvae. Without appropriate first foods, larval mortality approaches 100%.

Move the berried female to a separate, gently filtered rearing tank before the larvae hatch. A bare-bottom 5-gallon tank with a sponge filter turned to minimal flow works well. After she releases the larvae, return the female to the main tank. Feed green water or infusoria multiple times daily in small amounts. Larvae undergo several metamorphic stages over 1-2 weeks before settling into the juvenile shrimp form.

### How Long Until Juveniles Are Safe in the Main Tank

Juvenile ghost shrimp can be moved to the main tank once they have completed metamorphosis and resemble miniature adults — typically 2-3 weeks after hatching. At this point they are roughly 5-8mm long. Wait until they are at least 10mm before introducing them to any tank with fish, as smaller juveniles are easy targets even for "safe" species.

## Common Health Problems and Medication Warnings

Most ghost shrimp health issues come down to water quality or accidental chemical exposure. Infectious disease is rare in well-maintained tanks.

### Molting: Normal vs. Failed Molt

Ghost shrimp molt every 3-4 weeks as they grow, shedding their exoskeleton and growing a new one. A freshly molted shrimp looks pale and translucent and may hide for 24-48 hours — this is normal. Leave shed exoskeletons in the tank; other shrimp eat them to recycle calcium.

A failed molt occurs when the shrimp cannot fully extract itself from the old shell. This is usually caused by insufficient minerals (GH below 5) or sudden parameter changes. The shrimp becomes stuck and typically dies. Maintaining stable GH between 5-10 dGH prevents the vast majority of molting failures.

### Copper Toxicity and Invertebrate-Safe Medications

> **Copper kills all invertebrates — check every product label**
>
> Copper is lethal to ghost shrimp at trace concentrations. It hides in fish medications (many contain copper sulfate), some liquid plant fertilizers, and even untreated tap water in homes with copper plumbing. Always read ingredient labels before adding anything to a shrimp tank.

| Category            | Safe for Shrimp                    | Toxic — Never Use                     |
| ------------------- | ---------------------------------- | ------------------------------------- |
| Parasite treatment  | Praziquantel-based meds            | Copper sulfate (most ich treatments)  |
| Bacterial treatment | Erythromycin, Kanaplex             | Malachite green, formalin             |
| Plant fertilizer    | Copper-free formulas (check label) | Any fertilizer listing copper sulfate |
| Water conditioner   | Seachem Prime, Fritz Complete      | None common — but always verify       |

*Always verify ingredients before dosing any shrimp tank. When in doubt, move shrimp out first.*

If copper is accidentally introduced, perform an immediate 50% water change and add Seachem CupriSorb or activated carbon to the filter. Move surviving shrimp to a clean, cycled backup tank if losses have begun.

### Signs of Stress and Poor Water Quality

Watch for these red flags: shrimp clustering at the water surface (low oxygen), lethargy and refusal to forage (ammonia or nitrite exposure), cloudy or milky body color (bacterial infection or severe stress), and erratic swimming or "glass surfing" (parameter shock). Test ammonia, nitrite, nitrate, and pH immediately when you observe any of these behaviors. Small daily water changes of 10-15% are safer than one large change when correcting water quality issues.

## Where to Buy Ghost Shrimp

Sourcing matters. The difference between ghost shrimp that live two years and ghost shrimp that die within a week almost always comes down to where and how they were acquired.

### LFS vs. Online: What to Look For

Local fish stores are the best source for ghost shrimp. You can inspect the animals in person, check tank conditions, and avoid shipping stress — which is the leading cause of DOA losses with invertebrates. Big-box pet stores sell ghost shrimp cheaply, but their stock often comes from feeder-supply wholesalers with high mortality rates and poor handling practices. An independent local store that maintains clean tanks and knowledgeable staff is worth the extra trip.

### 6 Signs of Healthy Ghost Shrimp

- [ ] Active foraging behavior — shrimp should be moving and picking at surfaces, not sitting motionless
- [ ] Clear, transparent body with visible internal organs — not milky or opaque
- [ ] Intact antennae and all legs present — missing appendages signal stress or poor conditions
- [ ] No dead shrimp in the seller's display tank
- [ ] Tank water is clean and clear with no visible algae overgrowth or debris
- [ ] Store staff can confirm the species is Palaemonetes paludosus (freshwater), not a brackish grass shrimp

### Finding Ghost Shrimp at Local Fish Stores Near You

Skip the chain-store feeder tank and buy from an independent shop that treats ghost shrimp as livestock, not live bait. A good local fish store will keep them in clean, filtered tanks and can answer questions about their source and water parameters.

## Frequently Asked Questions

### How long do ghost shrimp live?

Ghost shrimp typically live 1-2 years in a well-maintained aquarium. Lifespan is heavily influenced by water quality, diet, and stress from incompatible tank mates. Stable parameters and a low-copper environment are the biggest factors in reaching the upper end of that range.

### Can ghost shrimp live with betta fish?

It's risky. Bettas often view ghost shrimp as food, especially in smaller tanks with little cover. Success depends on the individual betta's temperament. If you try it, use a heavily planted 10-gallon minimum and add the shrimp before the betta to reduce territorial aggression.

### How many ghost shrimp per gallon?

A safe guideline is 3-4 ghost shrimp per gallon in a species-only setup. In a community tank, stock more conservatively — around 1-2 per gallon — to account for bioload from other inhabitants and to reduce competition-related aggression.

### Why is my ghost shrimp turning white or cloudy?

A milky-white body usually signals a bacterial infection or severe stress, and the shrimp is unlikely to recover. A translucent-white appearance right after molting is normal and temporary. Persistent cloudiness in multiple shrimp points to a water quality issue — test ammonia, nitrite, and nitrate immediately.

### Do ghost shrimp eat algae?

Ghost shrimp are opportunistic omnivores and will nibble algae, but they are not effective algae controllers. Don't rely on them to clean a tank with an algae problem. Nerite snails or amano shrimp are far better choices if algae management is your goal.

### How do you tell male from female ghost shrimp?

Females are noticeably larger than males and develop a green egg saddle along the underside of the abdomen when gravid. Males are smaller and slimmer. Sexing is easiest once shrimp reach adult size (around 1-1.5 inches).

### What do ghost shrimp larvae eat?

Newly hatched ghost shrimp larvae are planktonic and require microscopic food — infusoria, green water, or commercially prepared powdered fry food. They cannot eat the same foods as adults for the first 5-7 days. Without appropriate first foods, larvae mortality is nearly 100%.
