Bamboo Shrimp

Quick facts

Overview

The bamboo shrimp (also sold as wood shrimp) is a big, peaceful filter-feeding shrimp that sits in the current and unfurls fan-shaped "hands" to comb food out of the flowing water. At 3–4 inches it is one of the largest freshwater shrimp commonly kept, and a genuinely mesmerising display animal in a planted community tank.

Here is the honest core of keeping it: it does not eat like other shrimp. It cannot be target-fed and it will not thrive by picking at the substrate. Everything about success with this species comes down to giving it flow plus suspended food — get that wrong and a "hardy-looking" shrimp quietly starves.

Water & tank

Aquarium Store Depot lists a temperature of 68–85 °F (~20–29 °C), a pH of 6.5–8.0, and a water hardness of 3–10 KH, in a freshwater tank of at least 20 gallons — and stresses stable parameters, because shrimp react badly to swings in chemistry. Ammonia, nitrite and sudden pH shifts are dangerous, so a fully cycled, mature, stable tank is mandatory before you add one.

Two setup points matter more than anything else. First, flow: the source calls for moderate-to-high water flow, because the shrimp feeds by filtering suspended particles from a current — "a clean, low-flow tank starves them". Second, copper: the source states copper is lethal, and even trace amounts from medications, pipes or fertilisers can wipe out shrimp — read every label before dosing anything into the tank.

Feeding

This is the make-or-break section. Bamboo shrimp are filter feeders, not scavengers — they cannot be target-fed and instead catch fine, suspended particles from the water column with their fans. Place the shrimp where moderate-to-strong flow carries food past it, and keep enough fine food in the water (for example powdered or finely crushed foods, or a dedicated liquid invertebrate food). The source is blunt: a shrimp walking the substrate picking at food is a hungry, starving shrimp — fix the flow and the food, not the shrimp.

Behaviour & tankmates

Bamboo shrimp are peaceful and community-suitable, sitting mid-to-low in the tank and posing no threat to fish. Their size actually helps them: the source notes they can share a tank with a betta in 20 gallons or more, being too large to be an easy target — though it flags a real trade-off, since the shrimp wants moderate current for feeding while a betta prefers calmer water.

Stability matters for how they look and behave. Keep water chemistry rock-steady, avoid anything copper-based near them, and remember they are escape artists during water changes — the source warns they climb siphon tubes and jump into buckets, so check your equipment and waste water for hitchhikers.

What to expect

Expect a large, peaceful, fascinating fan-feeder that will spend its day perched in the flow filtering the water — provided you supply both the flow and the suspended food it needs. Expect it to be sensitive to chemistry swings and instantly to copper, and to need a mature, stable, cycled tank. What you should not expect is a scavenger that cleans up leftovers on the bottom: if it is doing that, it is starving, and the setup needs fixing.

Myths, kindly busted

When to act

We triage, not diagnose — but these are worth a closer look (starting with a water test):

• A bamboo shrimp walking the substrate and picking at food instead of fan-feeding in the current — per the source this signals hunger/starvation; increase flow and add fine suspended food.
• Sudden death of the shrimp (or several inverts at once) shortly after adding a medication, fertiliser, or new tap water — treat as possible copper/chemistry exposure; stop dosing and review every product label.
• A shrimp that fails to complete a molt, or repeated molting problems — the source links successful molts to consistent mineral content (stable GH/KH); check that hardness and parameters are stable rather than swinging.
