Bamboo shrimp care: flow, feeding, tank size and tank mates
Bamboo shrimp, also sold as wood shrimp or fan shrimp, are the big, peaceful shrimp you see perched in a filter's current with their fans spread open. They don't graze like cherry shrimp. They catch food drifting past, and that one habit shapes everything about their care. Practical Fishkeeping says they aren't delicate, no more so than a cherry shrimp, but they are specialised feeders and many starve in tanks that are too small, too new or too clean.
Bamboo shrimp at a glance
| Trait | Bamboo shrimp |
|---|---|
| Scientific name | Atyopsis moluccensis (Atyopsis spinipes is often sold under the same name) |
| Size | Usually up to about 8 cm (3.1 in) |
| Origin | Flowing streams and rivers in Southeast Asia |
| Tank size | 60 × 30 × 30 cm (24 × 12 × 12 in), about 54 litres (14 US gallons), per Practical Fishkeeping; Aquariadise suggests at least 20 gallons (76 L) |
| Temperature | 23–29 °C (73–84 °F) per Practical Fishkeeping; Aquariadise lists a cooler 20–25 °C (68–77 °F) |
| Water | Not fussy but avoid extremes: about 6–15 °dGH, pH 6.5–7.5 |
| Diet | Filter feeder: powdered fry food, filter-feeder foods, tiny live and frozen foods |
| Temperament | Peaceful, gregarious and somewhat shy |
| Lifespan | Around two years, sometimes longer |
| Breeding in a home tank | Extremely unlikely; larvae need brackish or marine water |
The two temperature ranges overlap at about 73–77 °F, a sensible target if you're unsure.
Tank size and flow
Bamboo shrimp come from fast-flowing streams strewn with cobbles and boulders, and Practical Fishkeeping's advice is to think "flowing stream, not still pond." Its key setup points:
- Strong water movement. Aim for a turnover of 8 to 10 times the tank volume per hour. An additional filter or a powerhead can raise turnover.
- Plenty of oxygen. Lots of surface agitation; see air pumps for shrimp tanks.
- Perches and shelter. Cobbles, small boulders and wood create high-flow feeding spots and calmer resting pockets. Aquariadise suggests a tall piece of wood or rock in a high-current spot as a feeding perch; see driftwood and botanicals.
- Mature filtration. Bamboo shrimp are sensitive to ammonia and nitrite, so the filter must be well established. Aquariadise adds that a bigger tank means more food available; see how to cycle a shrimp tank.
Strong flow can pull small shrimp into an open intake, so cover it with a sponge if you also keep dwarf shrimp; see shrimp-safe filters.
Feeding: the part that matters most
Practical Fishkeeping calls feeding the biggest challenge. Bamboo shrimp don't forage much; they rely on suspended food. A common mistake is assuming they can live on natural detritus. That may work in large, mature tanks, but in smaller, newer or cleaner setups many simply starve.
- What to feed: powdered flake or fry foods, liquid or powdered filter-feeder foods (often sold for reef tanks), frozen copepods or lobster eggs, and tiny live foods such as microworms or vinegar eels (Practical Fishkeeping). Aquariadise adds baby shrimp food, algae powder and baby brine shrimp. See shrimp foods.
- How to feed: mix the food with tank water in a small cup and release it near the shrimp with a pipette or turkey baster, in small amounts 2 to 3 times a day. If the current scatters it too fast, turn the flow down briefly, then turn it back on.
- Don't broadcast-feed. Dumping lots of food into the tank pollutes the water quickly. Aquariadise suggests a bottom clean-up crew, such as Amano shrimp, for the particles the bamboo shrimp miss.
- The filter-sponge trick. Aquariadise notes that many keepers squeeze a filter sponge into the tank to release a cloud of particles, but only in a tank with a stable cycle.
Signs of a hungry bamboo shrimp
A healthy bamboo shrimp spends most of its time in the current with its fans open. Aquariadise says one that keeps using its fans to scrape food off the substrate is a serious sign to feed more. Practical Fishkeeping notes they will sweep the substrate, but it isn't their normal way of feeding. Keepers commonly report that a well-fed bamboo shrimp sits in one spot for hours; Aquariadise says it may sit so still that harmless algae grows on its shell.
Water quality and medications
- No copper or formalin. Practical Fishkeeping says copper and formalin medications are lethal to shrimps; move them to a hospital tank or choose a safe treatment such as salt if you need to medicate fish. See is copper toxic to shrimp.
- Condition every water change with a water conditioner that neutralises heavy metals such as copper (Practical Fishkeeping).
- Keep ammonia and nitrite at zero; see ammonia and nitrite.
- Fertilizer caution. Aquariadise warns that a bamboo shrimp could ingest fertilizer released when root tabs are stirred up; use shrimp-safe products. See shrimp-safe fertilizer.
Molting and lifespan
Like all shrimp, bamboo shrimp molt to grow. Aquariadise says a freshly molted shrimp hides for a few days while its new shell hardens, so provide plenty of hiding places. Missing legs usually grow back over later molts, according to Aquariadise. Practical Fishkeeping gives a typical lifespan of around two years, with longer possible; Aquariadise says 2 to 3 years. See how often shrimp molt.
Tank mates
Bamboo shrimp are entirely peaceful and too large to be seen as food by most small fish. Practical Fishkeeping says they are gregarious and can happily be kept in a group, and suggests:
- Good choices: fish that enjoy flowing water, such as danios; current-loving bottom dwellers such as some small catfish and hillstream loaches; and other peaceful shrimp, including cherry shrimp.
- Avoid: large fish that may see them as food, aggressive or overly curious species, and fish that prefer still water. Aquariadise also rules out cichlids and bettas.
Practical Fishkeeping's 2026 profile lists gouramis among still-water fish to avoid. An older Practical Fishkeeping answer says fan shrimps could live with angelfish or gouramis if they get enough to eat, so flow and feeding are the real tests. A semi-biotope "flowing stream" tank is often the best compromise. See shrimp tank mates.
Breeding
Don't expect babies. Practical Fishkeeping explains that bamboo shrimp larvae drift downstream to estuaries and the sea and need brackish or marine water to develop, which is hard to do at home. Males are slimmer with sturdier front legs. Like Amano shrimp, they won't overrun a freshwater tank.
Bamboo shrimp vs vampire shrimp
The African vampire shrimp (Atya gabonensis) is a close relative with the same peaceful nature and filter-feeding habits, but it grows larger, up to about 15 cm (6 in), according to Practical Fishkeeping. Aquariadise notes that vampire shrimp have a bluish shell, while bamboo shrimp never look blue.

Frequently asked questions
How big a tank do bamboo shrimp need?
Practical Fishkeeping suggests a tank of at least 60 × 30 × 30 cm (24 × 12 × 12 in), about 14 US gallons; Aquariadise says at least 20 gallons. A bigger, mature tank holds more natural food.
What do bamboo shrimp eat?
They filter tiny particles from the water. Target-feed powdered fry or filter-feeder food, frozen copepods or lobster eggs, or microworms near the shrimp 2 to 3 times a day.
Why is my bamboo shrimp sweeping the substrate with its fans?
It is probably hungry. Aquariadise says scraping the substrate with the fans is a serious sign to feed more; a well-fed bamboo shrimp sits in the current with its fans open.
Do bamboo shrimp need a strong current?
Yes. Practical Fishkeeping recommends a turnover of 8 to 10 times the tank volume per hour, with perches in the flow; add a second filter or a powerhead if needed.
Can bamboo shrimp live with cherry shrimp?
Yes. Practical Fishkeeping lists other peaceful shrimp species as suitable tank mates, and bamboo shrimp are entirely peaceful. Cover filter intakes so strong flow doesn't trap small shrimp.
How long do bamboo shrimp live?
Practical Fishkeeping gives around two years, sometimes longer; Aquariadise says 2 to 3 years with good water and enough food.
Can you breed bamboo shrimp in a home aquarium?
It is extremely unlikely. Their larvae need brackish or marine water to develop, according to Practical Fishkeeping.
