Bamboo shrimp – a curious guest in the aquarium
The bamboo shrimp (Atyopsis moluccensis) is a fascinating crustacean that’s bound to make you pause and take a closer look at your aquarium. What catches the eye are its strage umbrella-like structures, held out into the water current like miniature satellite dishes. This unusual appearance is a clever adaptation: the shrimp uses these fan-like appendages to filter food from the water. Feeding this way requires a special approach from the aquarist but don’t worry, it’s not complicated.
Habitat
The bamboo shrimp (Atyopsis moluccensis), also known as the filter-feeding shrimp, is a freshwater species naturally found in the flowing waters of India, the Malay Peninsula, and the islands of Sri Lanka, Samoa, and Okinawa. Because of its feeding method, it prefers moving waters, where it attaches itself to roots or rocks in streams and rivers, iideally positioned to filter out nutrient-rich particles from the current.
Appearance and build
The shrimp’s coloration can vary greatly, individuals may appear brown, beige, yellowish, reddish-brown or orange-brown. A lighter stripe runs along its back, and the sides of its body are marked with irregular lines. Its most distinctive features, however, are the feathery “umbrellas” located on the first two pairs of pereiopods (walking legs), which serve as specialized filtering tools. Bamboo shrimp typically grow to a length of 6 – 10 cm.
Water parameters for bamboo shrimp
While relatively adaptable to various water parameters, these shrimp are sensitive to sudden changes, making it important not to introduce them into a freshly set-up tank. Wait until the aquarium is fully matured before adding them.
They thrive in water temperatures between 24 – 26°C and prefer a pH range of 6.5 – 7.5. Clean, well-oxygenated water is essential, so be sure to install an efficient filter and perform regular water changes.
Newly purchased shrimp should be acclimated slowly. To do this, place the shrimp along with the water they came in into a separate container. Gradually add water from your aquarium into the container over time. Take it slow and make sure the shrimp can’t escape. After about 30 – 40 minutes, gently transfer them into the aquarium using a net or your hand. Never pour them in along with the water from the bag .
Aquarium requirements
You already know it’s a big shrimp. A sociable one, on top of that. So it is not a crustacean suitable for a small aquarium. Therefore, a tank in which you will create suitable conditions for several filter-feeding shrimps should not be less than 100 liters in volume. It will provide perfect space and conditions needed for a small group of peacful fish. These shrimp are notorious escape artists. That’s why cover the tank well and seal any gaps around cables and hoses with sponge or mesh.
To help them thrive, create areas where water flows directly from the filter across roots or rocks – these are the shrimp’s favorite spots for opening their “umbrellas” and feeding. Add some hiding places as well, where they can rest or molt. Like all crustaceans, filter-feeding shrimp molt regularly to grow, and during this time they require quiet, secure shelters for safety .
Food for bamboo shrimps
For bamboo shrimp (Atyopsis moluccensis), the form of food is critical. Their filtering “umbrellas” are adapted to catch fine particles suspended in the water. If they descend to the bottom searching for food, it’s a sign they aren’t getting enough suspended nutrients. Feed them finely crushed multi-ingredient or plant-based flake food for fish, such as Tropical Spirulina Flakes, Tropical 3-Algae Flakes, or Tropical Supervit Mini Flakes. However, fry foods in powder form are the best option. Great choices include: Tropical Mikro-vit Spirulina, Tropical Mikro-vit Vegetable, Tropical Micro-vit Basic and food with probiotic Tropical Pro Defence Micro. Add small amounts directly into the water current. Feed sparingly more frequent, smaller portions are better. Remember, bamboo shrimp are highly sensitive to poor water quality. Overfeeding can lead to excess nitrogen compounds and phosphates, which degrade water conditions.
Reproduction of bamboo shrimps
Although Atyopsis moluccensis is a freshwater shrimp, its larvae require saltwater to undergo full metamorphosis. For this reason, shrimp sold in stores are wild-caught rather than captive-bred.

Her research focuses on the effects of diet, supplementation, and natural additives on the health, condition, and reproduction of aquarium fish.
In her free time, she cares for her fish and cats, tends to plants, enjoys hiking, and stays active through sports.
