Ghost Shrimp
Invertebrates
The see-through scavenger that costs pennies and earns its keep!
On This Page▾
🤓 Did you know? Despite looking like a smaller, cheaper cousin of the cherry and Amano shrimp sold right next to them in the store, ghost shrimp aren't closely related to either. They belong to the family Palaemonidae, while cherry and Amano shrimp both belong to the unrelated family Atyidae, and each lineage independently evolved from marine ancestors into fresh water at a different point in history. Their famous hardiness is exactly why they're sold cheaply in bulk as feeder shrimp for larger fish, even though plenty of keepers keep them purely as pets.
🗓️ The first week
The numbers a new owner needs in the first week, each from the article it links to. Rows with no link come from the encyclopedia.
- Where yours came from
- Most ghost shrimp move through the trade as live feed with no screening or quarantine. Lethargy, hiding, refusing food, and losses inside a small group shortly after purchase are feeder-tank stress.Health guide →
- Recovery first
- A quiet, stable, planted tank and low expectations for two weeks. Losses in that window are common and usually not something you did.Enrichment guide →
- Tank size
- 5 gallons is the workable minimum, 10 gallons gives a small colony stability and room to forage.Setup guide →
- Temperature and water chemistry
- 72 to 82°F, pH 7 to 8, hardness 3 to 15 dGH. Wide tolerance does not mean ammonia and nitrite can read anything but zero before stocking.Setup guide →
- Filtration
- A sponge filter. It has no intake tube to pull in a shrimp, freshly molted ones especially, the way a hang-on-back does.Setup guide →
- Copper
- The non-negotiable rule: roughly 0.03 mg/L is the ceiling for invertebrates. Copper fish medications, some plant fertilizers, and old copper plumbing are all realistic routes, so confirm anything is invertebrate-safe before it goes in.Health guide →
- Cover
- Dense plants and driftwood, so a freshly molted shrimp can vanish for the hours it is soft. Fish and other ghost shrimp both target one.Setup guide →
- Molting, what normal looks like
- Going still and off food for an hour or more beforehand, then an empty shell in the tank. Young shrimp molt roughly weekly, older ones roughly monthly. Leave the shells in: they eat them for the minerals.Health guide →
- Molting, what failure looks like
- A solid white band where the shell should split cleanly at the head, trapping the shrimp between old and new shell, usually fatal. It traces to low calcium and hardness.Health guide →
- Feeding
- A small amount every day or two, a sinking wafer or a few pellets, with leftovers out after a few hours. They scavenge most of their own food, and they are a detritus crew more than an algae crew.Feeding guide →
- They eat each other
- Documented, not rare, and freshly molted shrimp are the target. Dense cover and consistent feeding both cut it.Feeding guide →
- Tankmates
- Prey or predator by size. A shrimp past roughly 1.5 inches is too big for most bettas to bother with; juveniles are at risk. Think about size in both directions, not the word "peaceful".Setup guide →
- Getting them into the tank
- A soft net, never hands, and a slow drip of 1 to 2 hours before they touch new water. A thin permeable shell makes sudden change far harder on a shrimp than a fish.Handling guide →
- Quarantine
- 2 to 4 weeks in a separate tank before new shrimp join an established one.Handling guide →
- Budget
- Well under $1 each in bulk, $1 to $3 individually as pets. Equipment roughly $40 to $130, and ongoing costs minimal. There is no practical vet care for a shrimp this size.Cost guide →
- Lifespan
- Roughly one year, some closer to two, shorter than an Amano's 2 to 3.Cost guide →
- Water changes
- Small and steady, since swings in hardness around a change trigger failed molts. Test nitrate rather than changing by the calendar.Aquarium Water Changes →
- A hot week
- Room air conditioning and a fan first, frozen bottles as a last resort, and the aeration running throughout: warm water holds less oxygen.Cooling an Aquarium Without a Chiller →
🚨 Emergency card
Test the water first, then act on these today. No vet treats a shrimp; prevention is the whole plan.
- Lethargy, hiding well past the first day or two, refusing food, and rapid losses inside a small group soon after purchase: feeder-tank stress
- A solid band around the body where the shell should split at the head, trapping the shrimp between old and new shell
- A whole group dying suddenly: ask what changed in the water, copper above all
Four habits prevent nearly all of this: quarantine new arrivals, confirm the cycle before stocking, keep copper at zero, and hold water chemistry steady for reliable molts.

❓ Frequently Asked Questions
What size tank do ghost shrimp need?
5 gallons is the workable minimum according to The Shrimp Farm, and 10 gallons gives a small colony more stability and room to forage. Bigger is always more forgiving with water quality, but ghost shrimp don't demand the larger footprint some other species do.
Why are ghost shrimp so sensitive to copper?
Like all freshwater shrimp, their gills and exoskeleton absorb dissolved metals efficiently, and copper is toxic to them at concentrations that barely register for fish. Commonly cited safety thresholds put copper at roughly 0.03 mg/L or lower as the ceiling for invertebrates, and copper-based fish medications, some plant fertilizers, and old copper plumbing are all realistic exposure routes. Keep it as close to zero as possible and confirm any medication or fertilizer is explicitly invertebrate-safe before using it.
Why does drip acclimation matter so much for shrimp specifically?
Because shrimp can't quickly regulate their internal water balance the way fish can, and a permeable exoskeleton means a sudden shift in water chemistry causes real osmotic stress fast. A slow drip, commonly run for 1 to 2 hours, lets a shrimp adjust gradually instead of being shocked by an abrupt change, and it meaningfully reduces the risk of a failed molt or death shortly after introduction.

🦐 Same Shelf, Different Families
Ghost shrimp are sold on the same store shelf as cherry shrimp and Amano shrimp, but they aren't close relatives of either. Ghost shrimp belong to a completely separate family from both, and all three ended up in the same aquarium aisle by convergent lifestyle, small, hardy freshwater scavengers, rather than by shared ancestry.
