The bamboo shrimp is a large, peaceful filter-feeding shrimp that uses fan-like front appendages to strain food particles from the water current. Fascinating to watch but dependent on a well-established tank with steady flow and suspended food, it is best for keepers who can meet its specialized filter-feeding needs.

Part of the Freshwater shrimp
Small atyid and palaemonid shrimp kept in planted aquariums as peaceful algae-grazers and colorful colony animals. Care ranges from beginner-friendly Neocaridina to demanding species like the Sulawesi shrimp that need precise, stable water chemistry.
From the minimum an animal needs to be kept humanely, up to the ideal setup. Bigger is almost always better — minimums are floors, not targets.

Minimum
Planted tank with current
20 gal (≈ 76 L), gentle current
Atyopsis moluccensis is a filter-feeder — needs current (a powerhead or HOB outflow) to fan plankton from. Mature, established tanks with biofilm and powdered foods only; a brand-new tank will starve them.
Recommended
Larger planted aquarium
30 gal (≈ 114 L) with directed flow
A 30-gallon planted tank with driftwood perches placed in flow, regular powdered/liquid filter-feeder food, and stable parameters. Keep in groups of 3+ for natural behaviour; community-safe with peaceful fish.

Ideal
Mature aquascape with strong flow
40+ gal, planted, river-style flow
A river-style aquascape with dense planting, driftwood structure, and a strong directional current that bamboo shrimp can perch in to fan-feed. Closest to wild Asian-river habitat.

Larva
Most marine invertebrates hatch into microscopic planktonic larvae (such as the zoea of crustaceans or the bipinnaria/veliger of echinoderms and mollusks) that drift and feed in the water column. The larva looks nothing like the adult and undergoes major reorganization.

Juvenile
After settling out of the plankton, the juvenile takes on a recognizable miniature of the adult body plan — a tiny shell, a small star, or a translucent shrimp. Crustaceans grow by molting, shedding the exoskeleton to enlarge.
Adult
Adults reach full size and reproductive maturity with the species' mature shell, shape, or coloration. Many continue to molt or grow throughout life, and some show sex differences in size or claw/appendage shape.
Habitat & enclosure
A mature, cycled tank of at least 75 L (20 gal) gives the swimming volume and biofilm-rich water it needs. Keep temperature 22-28 C (72-82 F), pH 6.5-7.5, with soft to moderately hard water. Critically, it requires moderate to strong, steady water flow to bring food to its fans, so position it where current passes a perch (driftwood, rock, intake area). Subdued planted-tank lighting is fine; flow and food availability matter most.
Substrate
Inert gravel or sand is fine; the key aquascaping goal is to provide raised perches such as driftwood, large rocks, or hardscape positioned in the current. Plants and a mature, biofilm-rich layout improve natural food availability.
Equipment & setup
Provide a filter or powerhead that creates moderate, directional flow past the shrimp's favorite perch, with a sponge guard so the shrimp isn't injured. A heater holds tropical temperatures, and standard lighting suffices. Avoid over-aggressive mechanical filtration that strips out all the fine particles the shrimp needs to eat.
Diet
An obligate filter feeder that fans plankton, biofilm, fine detritus, and powdered foods out of the water column rather than scavenging the bottom. In a mature tank it filters naturally, but most need supplemental feeding: dose finely powdered/crushed flake, shrimp filter-feeder foods, or phytoplankton near the flow. A shrimp seen scraping the substrate with its fans is starving and needs more suspended food.
Behavior & temperament
Completely peaceful, plant-safe, and non-aggressive; it ignores tankmates entirely and perches in the current. Safe with peaceful community fish and other shrimp, but avoid boisterous or fin/leg-nipping species and any tankmates that outcompete it for fine food. It does not need a group, but several can be kept together where flow and food are sufficient.
Health
The most common cause of death is slow starvation in tanks that are too clean or have too little flow. It is sensitive to copper, ammonia/nitrite, and parameter swings, and like all shrimp is vulnerable around molting if mineral levels are low. Color may fade or shift with mood and molt cycle, which is normal.
Tips, DIY & hacks
Drip-acclimate slowly and add to a fully mature tank, not a new one, so suspended food is present. To target-feed, turn off heavy filtration briefly and squirt powdered food into the current near the shrimp. Breeding in captivity is very difficult because larvae require brackish/saltwater to develop, so most stock is wild-caught.
