Ghost / Glass Shrimp

Palaemonetes paludosus

Eastern and Southern United StatesBeginner

TL;DR, Ghost / Glass Shrimp

Cheap and disposable in big pet stores but a legitimate keeper species. Larger ghost shrimp can occasionally nip small fish or other shrimp.

Ghost / Glass Shrimp (Palaemonetes paludosus) reaches 3–5 cm and needs a minimum tank of 40 L with a colony of 6+. Native to Eastern and Southern United States. Aim for 20–28 °C, pH 7.0–8.0, 5–15 dGH, and 200–400 ppm TDS. Lifespan: 1–2 years. Breeding: easy in fresh water (some sources say brackish for larvae). Diet: omnivore / scavenger, Pretty much anything, pellets, flake, blanched veg, frozen foods. Plant-safe: Yes. Tank-mates: Most community fish, semi-aggressive, may pester slower fish.

Who it lives with

Tank-mate safety and the species this one is documented to thrive (or fail) alongside.

Good tank mates

Most community fish (they're 3–5 cm). Other ghost shrimp.

Avoid

Large cichlids, predatory fish. Avoid mixing with small Neocaridina — ghost shrimp are slightly territorial and bigger.

Pro tips

Hard-won lessons from the tank.

Hand-pick from the store tank — choose lively, full-bodied individuals. Avoid any that look milky or have a 'cottony' growth. They're underrated display shrimp once acclimated and fed properly. Will eat small fish in extreme cases (uneaten food preferred).

Failure modes, in order of how dramatic the fix is.

Health

Diseases

Robust. Usually arrive in mass-bred feeder bags in chain stores — many are stressed, weak, and die in week 1. Quality cherry-picked specimens are very hardy.

Common mistakes

Common mistakes

1) Buying 'feeder' ghost shrimp expecting them to live — most are wholesale-stressed and weak. 2) Assuming they're shrimp-tank-only — they handle community tanks fine. 3) Underestimating their size potential — adult females reach 5 cm.

How to care for it

The practical routine, read top to bottom.

  1. Tank setup

    40 L+. Tolerates wider parameters than dwarf shrimp. Otherwise standard shrimp setup.

Native rangeEastern USA
Origin · Eastern and Southern United States

Freshwater swamps, rivers, and lakes across the southeastern and eastern United States. Often in brackish estuaries too.

Behavior & breeding

How they pair, reproduce, and grow.

  1. Stage 1
    Telling them apart

    Sexing

    Females larger, fuller-bodied, may show green or yellow saddle/eggs. Males slimmer.

  2. Stage 2
    Molting cycle

    Molting

    Every 4–6 weeks.

  3. Stage 3
    Life stages

    Lifecycle

    Mixed literature: some sources report direct freshwater development; others report larval phase requiring brackish. P. paludosus appears to be one of the few palaemonid species that completes its lifecycle entirely in fresh water.

Variants & identification

The named cultivars and the lookalikes worth flagging.

Color grades / variants

No grading — transparent body with some opaque internal organs visible. Females may carry green eggs visibly. Pregnant females are extremely photogenic.

Frequently asked questions

Direct answers to the questions search engines and AI assistants surface most often about this species.

What tank size do Ghost / Glass Shrimp need?

Minimum tank: 40 L with a colony of 6+. Ghost / Glass Shrimp (Palaemonetes paludosus) reach 3–5 cm as adults.
