Fishori provides conservative planning guidance, not guarantees.
Based on typical aquarium care sources; details may vary between setups. Use the numbers here as planning defaults — your room, water, and routine still shape real-world outcomes.
A spectacular filter-feeding shrimp for a mature planted tank with real flow. Starves quietly in low-flow tanks. Not a beginner shrimp despite the peaceful tag.
Best for
Mature planted tanks 80L or more with areas of detectable current that allow filter feeding.
Avoid if
Your tank is under six months old, lacks consistent algae and biofilm, or has no medium-flow zone.
Top things that go wrong
- Shrimp & snails. Compatible with other shrimp and snails. Will not threaten anything; the question is whether the tank feeds them at all.
Common mistakeA still or low-flow tank. Bamboo shrimp need to spread their fan arms in moving water; without flow they starve quietly over weeks.
What most shops don't tell you
- 1.Adult bamboo shrimp moult dramatically and look dead for hours afterwards. The pale empty shell on the substrate is the shed, not the shrimp.
- 2.Bought for a low-flow planted nano with no powerhead. The shrimp climbs the highest point looking for current that is not there, then starves in three to four months.
- 3.Fed pellets that fall to the substrate. Bamboos feed from the water column. Food on the floor goes to fish and snails, not the shrimp.
- 4.Not a beginner shrimp despite the peaceful tag. Bamboos starve in clean low-flow tanks because there is nothing in the water column for them to filter. They need real flow over a perch, finely powdered food, and a mature tank with biofilm in the water. A bare 40L with a sponge filter kills them in months.
About this species
Bamboo shrimp are the largest dwarf shrimp in the hobby, reaching 9 cm. They are filter feeders. The two front legs unfold into feather fans and the shrimp sits on a high perch in the current, combing particulate food out of the flow. A bamboo shrimp picking at the substrate is starving.

Common setup sketches
Conservative patterns from Fishori fields — still run the pair checker for every species you add; sketches are not a stocking guarantee.
Rough 90L+ layout: one calm centrepiece, 8–12 small tetras/rasboras, 6–8 corydoras-type bottom fish — verify every name in the pair checker before buying.
Safe directions on file include: Harlequin Rasbora, Neon Tetra, Corydoras Catfish.
Tank mate intelligence
Use the "Often compatible" lists as a shortlist, not a stocking plan. Always run the pair tool and check the footprint of your actual tank first. Verify behaviour for Bamboo Shrimp against your own reading before you buy.

Behaviour, temperament, and what to watch
Prose and lists come from the same record: read temperament first, then glass-level signals so you are not surprised after day three.
Bamboo Shrimp is peaceful in mixed company.
Stress / aggression triggers on file
- Sudden crowding
- Poor water quality
Fin nipping: Not a habitual fin-nipper, but individuals can still test fins under stress or in a crowded tank.
Predation: Not a predator toward similarly-sized community fish. The usual community caveats about mouth size still apply for very small fry or shrimp.
Territory: Not strongly territorial, but still claims a working area in the tank. Give it room to settle without overlapping the next species' patch.
Planted tanks: good — easy plant ideas
In the glass: typical and warning signs
- Often calm on the glass — bursts of movement around food or tank disturbance.
- Clamped fins, gasping at the surface, hiding non-stop, or refusing food after the first week.
- Rapid breathing when parameters swing — fix ammonia/nitrite first, then reassess mates.
- Low listed risk — still watch new introductions.
- Separate or rehome if injuries appear, one fish is pinned, or feeding becomes a daily chase.
- If water is stable but behaviour worsens, reduce stocking or remove the highest-impact species first.
Fish behaviour can vary between individuals and tank setups. Always observe new fish closely after introduction.
Care parameters: water, food, inverts, grouping
Chemistry and group rules sit here so you are not re-reading the same line from tank mate or temperament blocks. Swim level is in the plan grid above.

Diet
omnivore
Mixed diet: a quality flake or pellet as the staple, with frozen or live foods two or three times a week.
Shrimp & snails
Compatible with other shrimp and snails. Will not threaten anything; the question is whether the tank feeds them at all.
One or two in an 80L. Bamboos do not need company and competition for filter-feeding perches wastes food.
Breeding behaviour depends on the species. Research before you buy a mixed-sex group of this fish.
- Real flow. A powerhead or canister return rated for at least 6 to 8 turnovers an hour aimed across a perch.
- Powdered or suspension food (golden pearls, dust feeds, baby brine shrimp). Pellets and flakes alone are not enough.
- A mature tank running at least three months with steady biofilm. A new tank with sterile water starves a filter feeder fast.
- Hides at the substrate level for moulting weeks when the shrimp stays out of the open.
- Tank volume meets or exceeds 80L published minimum for adults.
- Heater can hold 22–28°C without cooking cooler-water tank mates.
Explore and stocking hubs
Same library as the rest of Fishori: tank-mate index for this species, category peers, guides, and litre-based stocking lists where min tank on file is within the hub volume.
Plan with tools
Pair-level rules and multi-fish stocking use the same conservative engine — add this fish in the tank builder only after mates pass pair checks.
Filtration & heating
A 80L minimum tank needs a filter rated for at least 320L/hr turnover and a heater to hold 22–28°C reliably.
Plant suggestions
Bamboo Shrimp does well in planted tanks. Plants compatible with 22–28°C and pH 6.5–7.5:
Profile status: partially verified · Evidence tier: medium · 2 linked source(s). Fishori does not fabricate citations.
Fishori uses conservative planning rules based on these sources.
Confidence is explained in the summary at the top of this page (same tier as here), not repeated below.

Evidence notes
- Bamboo shrimp will not breed in freshwater. Larvae need brackish water for the planktonic stage, then return to freshwater as juveniles. Aquarium specimens are wild-caught.
- Filter feeding works in the right tank. A bamboo shrimp parked in the outflow of a canister filter in a planted 100L lives for years; the same shrimp in a low-flow nano starves within months even with target feeding.
- Fishori profiles work from typical aquarium trade sizes and hobby care norms. Specialist site checks and literature review for this species are not yet recorded here, so the ranges on this page are planning numbers rather than guarantees.
