Bamboo Shrimp Care Guide - Setup, Feeding & Breeding

Bamboo Shrimp, Atyopsis moluccensis, are large, peaceful freshwater crustaceans recognised by their sturdy bodies, feathery filtering fans and attractive reddish-brown, tan or grey colouring. Their camouflage can change with age, mood and surroundings, and many individuals show a pale stripe along the back.

Rather than searching through the substrate for food, these shrimp perch in the current with their specialised fans extended. Tiny particles carried by the water are captured and transferred to the mouth, creating a fascinating feeding behaviour that makes them especially interesting to watch.

They are generally calm and non-aggressive, spending much of their time resting on wood, rocks or other elevated surfaces. When startled, they can move surprisingly quickly, using their swimmerets and tail to dart away before settling again.

In nature, Bamboo Shrimp live in oxygen-rich streams and rivers where flowing water continually delivers suspended food. Their specialised lifestyle is closely linked to these currents, and they are among the most distinctive filter-feeding invertebrates kept in freshwater aquariums.

Bamboo Shrimp are native to Southeast Asia, particularly fast-flowing rivers and streams on islands and mainland areas around Indonesia, Malaysia and Thailand. They inhabit freshwater systems connected to coastal waters, where their larvae complete part of their development.

A minimum aquarium of around 75 litres is recommended for a single Bamboo Shrimp, with a footprint of at least 60 x 30 cm; a larger tank is preferable for several specimens or a community. Provide mature biological filtration, good oxygenation and a gentle, well-directed current that carries fine food particles past elevated perching places. Use smooth gravel or sand, with driftwood, rounded rocks, sturdy plants and shaded retreats. Avoid sharp decorations and ensure the shrimp cannot be drawn into an exposed filter intake.

Adults can reach about 7–10 cm (2.8–4 inches) in total length. Females are usually larger and more robust than males, while males tend to be smaller and slimmer.

Bamboo Shrimp feed by filtering fine suspended particles from the water. In a well-established aquarium they may obtain some food from natural micro-organisms and gentle current flow, but they often need supplementary feeding with finely powdered shrimp foods, spirulina, suspended algae foods, crushed flakes or other appropriately sized powdered preparations. Add small amounts to the current so the food remains available without causing a buildup of waste.

Bamboo Shrimp are peaceful and can be kept with small, community-safe fish such as neon tetras, harlequin rasboras, ember tetras, otocinclus, small Corydoras and other non-aggressive species. They also coexist well with peaceful freshwater snails and other calm shrimp, provided there is enough food and shelter. Avoid large cichlids, aggressive barbs, loaches, crayfish and any fish capable of swallowing or repeatedly harassing them.

Bamboo Shrimp are rarely bred successfully in ordinary freshwater aquariums. Females carry eggs beneath the abdomen, but the larvae need brackish water and a specialised rearing process before they can return to freshwater. Commercially available specimens are therefore usually wild-caught or produced through specialist breeding programmes. Stable, mature conditions and excellent water quality are important if a female is carrying eggs.

Females are typically larger-bodied, with a broader abdomen and a more substantial build. Males are generally smaller and narrower; mature males may also have noticeably enlarged front walking legs, although sexing young specimens can be difficult.
