What is a ghost shrimp?
The ghost shrimp (Palaemonetes paludosus), also sold as the glass shrimp or freshwater glass shrimp, is one of the most striking invertebrates in the freshwater hobby — not for colour, but for the complete absence of it. The body is fully transparent: internal organs, the digestive tract, even partially digested food are all visible to the naked eye, making every individual a living anatomy lesson.
Despite being mass-produced as feeder shrimp for cichlids and other predators, ghost shrimp are capable, active animals that serve a genuine role in a community or nano tank. They pick algae, scavenge uneaten food, and process detritus from the substrate and hardscape, making them one of the most cost-effective clean-up crew members available. Kept in a peaceful setup, they reward the patient observer with constant, industrious activity.
Where do ghost shrimp come from?
Ghost shrimp are native to the eastern and southeastern United States, where they inhabit slow-moving rivers, ponds, swamps and grass-lined streams from Illinois to Florida. In the wild they occupy shallow, densely vegetated shallows with soft substrate — their transparency is excellent camouflage in clear, sunlit water over sandy or silty beds.
Because the wild range spans a broad latitudinal band, the species tolerates a wider temperature range than many tropical aquarium shrimp — from as cool as 18 °C (64 °F) up to 28 °C (82 °F). This also means they are one of the few shrimp that can be kept comfortably in an unheated tank in a warm room, though they do best at the middle of their range.
What size tank does a ghost shrimp need?
The minimum practical tank is 38 litres (10 gallons). Although a single ghost shrimp could technically survive in less water, the frontmatter minimum of 38 L reflects the need to keep a group of at least six together — smaller volumes make it difficult to maintain stable parameters for that many animals.
Ghost shrimp are bottom-dwellers that roam every inch of the substrate and lower hardscape. Footprint (surface area) matters more than tank height, so a wider, shallower tank is preferable to a tall column. A planted nano or species tank in the 38–75 L (10–20 gal) range with a sandy or fine-gravel substrate, patches of java moss or hornwort, and a few ceramic caves or leaf litter piles is close to ideal. Sponge filters or pre-filtered intakes are strongly recommended — unguarded power filter intakes can trap or kill small shrimp.
What water parameters do ghost shrimp need?
- Temperature: 18–28 °C (64–82 °F). A mid-range of 22–25 °C (72–77 °F) balances activity and lifespan well.
- pH: 6.5–8.0 — ghost shrimp are unusually tolerant across the pH spectrum compared to other ornamental shrimp.
- Hardness: 3–15 dGH. Moderately hard water supports healthy molting; very soft water can lead to incomplete molts.
- Ammonia / nitrite: 0 ppm at all times. Invertebrates cannot tolerate even low-level ammonia as well as fish can.
- Nitrate: Below 20 ppm where possible; regular 20–25 % water changes weekly maintain this easily.
The single most important water-quality concern for ghost shrimp is copper. Trace copper — from fertilisers, some medications, old copper pipes or even certain dechlorinators — is acutely toxic to all shrimp. Read every product label before adding it to a shrimp tank.
What do ghost shrimp eat?
Ghost shrimp are omnivores with a generalist, scavenging feeding style. In the tank they will graze on algae films, biofilm on hardscape, and any uneaten fish food that reaches the substrate. This scavenging behaviour is exactly what makes them valuable as clean-up crew.
For a healthy colony, supplement natural grazing with:
- Sinking algae wafers or shrimp pellets — a small piece every one to two days is plenty.
- Blanched vegetables — courgette (zucchini), spinach or cucumber left for a few hours before removal.
- Frozen or freeze-dried daphnia and bloodworms — occasionally, as a protein boost, particularly during breeding conditioning.
Avoid overfeeding; uneaten food rots quickly and spikes ammonia. Ghost shrimp are efficient enough that a lightly stocked planted tank may need almost no supplemental feeding at all.
Are ghost shrimp aggressive — and what fish can live with them?
Ghost shrimp are thoroughly peaceful and pose no threat to fish or other invertebrates. They will not nip fins, chase tankmates, or compete aggressively for food. In fact, the primary compatibility concern runs in the opposite direction: almost any fish capable of fitting a 4 cm (1.6 in) shrimp in its mouth will eventually eat one.
Safe companions are small, peaceful fish that are not predatory by instinct: ember tetras, neon tetras, small rasboras, otocinclus, pygmy or salt-and-pepper corydoras, and dwarf pencilfish. Other peaceful invertebrates — nerite snails, mystery snails, amano shrimp — are excellent tankmates. Avoid angelfish, gouramis larger than a dwarf gourami, betta fish, cichlids, goldfish, and any barb or loach with a reputation for shrimp predation.
For a comprehensive, filterable list of compatible and incompatible species, see Ghost Shrimp tank mates.
How do ghost shrimp molt — and what does sexual dimorphism look like?
Ghost shrimp molt (shed their exoskeleton) as they grow, typically every three to eight weeks depending on age, water temperature and nutrition. After molting, the shrimp is briefly soft and vulnerable — it will hide until the new shell hardens, which takes 24–48 hours. Leave the shed exoskeleton in the tank; the shrimp will often eat it to reclaim minerals.
Incomplete molts or “molt stuck” problems are usually linked to low mineral content in the water (too soft) or iodine deficiency. Moderately hard water (above 5 dGH) and a balanced diet generally prevent this.
Sexing is straightforward in adults. Females are noticeably larger than males and develop a distinctive green saddle — a row of eggs visible along the upper back beneath the carapace when gravid. Males are smaller, slimmer and entirely plain. The green saddle of a berried female is often the first sign of a healthy, reproducing colony.
How do ghost shrimp breed?
Ghost shrimp breeding is rated medium difficulty — not because the shrimp are reluctant breeders, but because the larvae have specific needs that differ from adult care. In a stable, well-fed tank, females will become gravid (berried) regularly and without much intervention.
After fertilisation, the female carries the eggs tucked beneath her tail for roughly 2–3 weeks, fanning them constantly to oxygenate them. When the eggs hatch, the larvae are planktonic — unlike cherry shrimp, which hatch as miniature adults, ghost shrimp larvae spend 1–3 weeks drifting as tiny, free-swimming organisms before settling into the juvenile shrimp form.
This larval stage is the bottleneck. In a community tank, most larvae are eaten or sucked into filters. Successful breeding requires:
- A dedicated breeding or grow-out tank with a sponge filter only.
- Infusoria or first-foods fine enough for planktonic larvae (commercial liquid fry food, phytoplankton, or green water work well).
- Gentle water quality management — larvae are more sensitive than adults.
Once juveniles reach about 5 mm and look like tiny shrimp, they can be moved to the main tank or raised on the same foods as adults.
What are common ghost shrimp diseases?
Ghost shrimp are generally robust, but a few problems arise regularly in home aquaria:
- Failed or incomplete molts — the shrimp becomes stuck mid-shed and dies. Caused by water that is too soft, mineral deficiency, or sudden parameter shifts. Maintain stable, moderately hard water to prevent it.
- Bacterial infections — a milky-white or opaque appearance in the body (distinct from the normal translucency) can indicate a bacterial infection, often secondary to poor water quality or injury. Prevention is almost entirely a matter of clean water and avoiding physical damage.
- Parasites (Vorticella, Scutariella) — small organisms sometimes visible on the body or antennae. These are opportunistic and more common in stressed or newly imported shrimp. Quarantine all new shrimp before adding them to an established tank.
- Copper toxicity — not a disease but the single most common cause of sudden shrimp death. Any trace copper in the water column can wipe out an entire colony in hours with no other warning signs.
Health note: invertebrate disease diagnosis is less well-documented than fish disease. Before treating a shrimp tank with any medication or remedy, confirm the diagnosis against a reputable aquarium invertebrate resource — many standard fish medications contain copper or other compounds that are lethal to shrimp even at labelled doses.
How long do ghost shrimp live?
Ghost shrimp live 1–2 years under aquarium conditions, which is on the shorter end for ornamental invertebrates. Wild populations live similarly short lives, driven by high predation pressure and seasonal fluctuation. In a well-maintained tank with stable water, good nutrition and no copper exposure, individuals regularly reach the upper end of that range.
The short lifespan is offset by the ease with which ghost shrimp breed: a healthy colony is largely self-sustaining if larvae have somewhere safe to develop. Many keepers maintain a small breeding tank alongside the display tank specifically to keep the colony numbers topped up. At typical purchase prices of less than a dollar each, ghost shrimp are also among the most economical invertebrates to replace when attrition does occur.
Frequently asked questions
Can ghost shrimp live with fish?
Yes, provided the fish are small and peaceful — think ember tetras, otocinclus or small corydoras. Any fish large enough to swallow a 4 cm shrimp whole will eat them, including common community fish like angelfish, gouramis and large barbs. A species-only or nano setup gives them the best survival odds.
Why do my ghost shrimp keep dying?
The most common culprits are copper (fatal in trace amounts — check fertilisers and medications), an uncycled tank with ammonia spikes, or simply stress from an aggressive tankmate. Keep the water clean with regular partial changes, avoid any copper-based products, and give them plenty of cover like moss or fine plants.
What you need to keep a ghost shrimp
The baseline is a heated, filtered 38 L+ tank: a reliable heater to hold 18–28 °C (64–82 °F), a gentle filter that won't batter a ghost shrimp in the current, and a tight-fitting lid. Cycle the tank fully before adding any fish.
