Ghost shrimp are an excellent choice for those looking for an efficient cleanup crew in freshwater aquariums. They are not only affordable but also engaging to observe as they scuttle around. Also known as grass shrimp or glass shrimp, these transparent little scavengers are popular in community tanks, planted tanks, and even breeding setups because they constantly graze, pick up leftover food, and add lively movement to the bottom and mid-levels of the aquarium. In this complete guide, we will provide information on how to set up the best ghost shrimp aquarium, what to feed, ideal water conditions, breeding expectations, compatible fish tank mates, and how to build a planted environment where they thrive.
Ghost Shrimp Overview
Ghost shrimp (Palaemonetes paludosus) are small freshwater shrimp commonly sold under the names glass shrimp and grass shrimp. In the aquarium trade, “ghost shrimp” may refer to a few similar-looking species, but most are transparent shrimp in the Palaemonidae family. Their see-through bodies make them fascinating to observe. You can often see their digestive tract, eggs in females, and even movement inside during feeding.
Typical ghost shrimp size ranges from 1 to 2 inches, depending on the exact species and conditions. They are active scavengers that spend the day walking over plants, substrate, and décor searching for microfood, biofilm, detritus, and leftovers. In healthy conditions, they molt regularly, which is essential for growth and survival.
Why Should I Have Ghost Shrimp for My Tank?
Ghost shrimp are popular for a reason: they provide a lot of value for very little cost. They’re also one of the easiest ways to add more “ecosystem energy” to your aquarium without adding more fish. Here are the biggest benefits of adding ghost shrimp to a tank:
- They help clean up leftover food and reduce waste buildup
- They graze on soft algae film and biofilm (especially in planted tanks)
- They add movement and interesting behavior without aggression
- They’re affordable and easy to find in most fish stores
- They can serve as a “test shrimp” for water quality in a mature tank
- In the right conditions, ghost shrimp breeding is possible and fascinating
Create the Ideal Environment for Ghost Shrimp
Tank Size
Ghost shrimp can live in small aquariums, but stability improves dramatically in tanks 10 gallons or larger. A 5-gallon tank can work if parameters are stable and there are no predators, but it’s less forgiving if temperature or water chemistry swings. Because ghost shrimp are social and more confident in groups, many keepers start with 6–10 shrimp and grow from there.
Filter
Ghost shrimp do best with gentle filtration that won’t suck them into the intake, especially if you plan to keep babies. Here are some recommended filters for ghost shrimp tank: Sponge filter (top choice for shrimp tanks), hang-on-back filter with a pre-filter sponge, and low-flow internal filter with protected intake. Sponge filters are especially helpful because they grow biofilm, which becomes a natural food source and improves shrimp survival.
Water Parameters
- Temperature: 70–78°F (21–26°C)
- pH: 6.8–7.8
- GH: moderate (important for molting)
- KH: stable
- Ammonia/Nitrite: 0 ppm
- Nitrate: ideally under 20 ppm
Substrate
Ghost shrimp aren’t picky about substrate, but the best substrate supports biofilm and shrimp activity. Great options include: Fine gravel, sand, and planted substrate (works well in planted shrimp tanks). Darker substrates often make ghost shrimp more visible and help them feel more secure. Add driftwood, rocks, and moss for extra grazing surfaces and hiding spots.
What Do Ghost Shrimp Eat?
Ghost shrimp are omnivores and scavengers. In a mature aquarium, they’ll constantly pick at biofilm, detritus, and leftover fish food, but they still need targeted feeding for best health and growth.
Great shrimp food includes:
- Shrimp pellets or granules
- Algae wafers (small pieces)
- Blanched vegetables (zucchini, spinach)
- Occasional protein (bloodworms, brine shrimp)
- Leaf litter or botanicals (boosts biofilm and grazing)
Feeding tips:
- Feed small amounts 3–5 times per week (more if shrimp-only)
- Remove uneaten food after a few hours
- Use a feeding dish to control mess and observe eating behavior
Ghost Shrimp Breeding
Ghost shrimp breeding can happen in freshwater, but survival depends heavily on tank setup and food availability. Females carry eggs under their abdomen (berried females), and once eggs hatch, tiny larvae may appear. Some ghost shrimp species produce larvae that need special care, while others may successfully develop in freshwater. Because “ghost shrimp” can refer to several similar species, breeding outcomes can vary. Still, many hobbyists successfully raise baby shrimp in well-planted, mature tanks with stable parameters.
Breeding success improves when:
- The tank is shrimp-only or very peaceful
- Filtration is shrimp-safe (sponge filter preferred)
- There is plenty of moss and micro-hiding space
- The tank has natural biofilm and microfoods available
What Fish Can Live with Ghost Shrimp?
Fish compatibility is one of the biggest deciding factors for a successful ghost shrimp aquarium. Many fish will eat shrimp, especially baby shrimp, so the safest approach is either shrimp-only or shrimp with very peaceful tank mates.
Good Fish Companions
- Small Rasboras
- Small peaceful Tetras (species-dependent)
- Otocinclus
- Corydoras (in larger tanks; may compete but usually peaceful)
Avoid or Use Extreme Caution:
- Bettas (often hunt shrimp)
- Gouramis (many pick at shrimp)
- Cichlids
- Barbs (some can be aggressive/nippy)
- Any fish large enough to eat shrimp
If your goal is maximum shrimp survival, keep ghost shrimp with small, peaceful fish, or skip fish entirely.
Enhance Ghost Shrimp Tank with Aquatic Plants
Plants dramatically improve ghost shrimp success because they create shelter, reduce stress, and provide surfaces for grazing. The more surfaces you have, the more biofilm grows, and the easier it is for shrimp to find food naturally. A planted tank also helps maintain water stability, which supports better molting and overall shrimp health.
Great plant choices for ghost shrimp tanks include:
- Mosses (perfect baby shrimp protection)
- Floating plants (soften light and reduce stress)
- Rhizome plants on wood/rock (extra grazing surfaces)
- Fine-leaf plants that create dense hiding zones
Conclusion
Ghost shrimp are one of the most useful and beginner-friendly invertebrates you can add to a freshwater aquarium. They help clean up leftovers, bring nonstop movement, and create a more balanced ecosystem when kept in stable conditions. With proper ghost shrimp care, a shrimp-safe filter, consistent water parameters, and a planted setup for shelter and grazing, you can keep ghost shrimp healthy and potentially even see breeding behavior.

FAQs
How long do ghost shrimp live?
Average ghost shrimp lifespan is about 1 year, though healthy, well-sourced individuals can live longer in stable tanks. Lifespan depends heavily on water quality, diet, and molting success. Feeder-grade ghost shrimp may have shorter lifespans due to stress and poor handling before purchase.
Differences between female and male ghost shrimp?
Female ghost shrimp are usually larger and may show a visible “saddle” (developing eggs) behind the head. When berried, females carry eggs under the abdomen, which is the easiest way to identify them. Males are typically slimmer with a more streamlined body shape.
How big do ghost shrimp get?
Most ghost shrimp reach 1–2 inches in size depending on species and conditions. In well-fed tanks with stable parameters, they may grow closer to the upper end of that range. Their long antennae can make them appear larger than their actual body length.
