About

The bamboo (wood or fan) shrimp is a large, peaceful filter-feeding shrimp that anchors in the current and unfurls four fan-like appendages to strain micro-particles from the water column. Unlike grazing dwarf shrimp it does not scrape surfaces; it depends entirely on suspended food carried by good flow, so it thrives only in a mature, well-fed aquarium with strong circulation. Colours shift from tan to deep red-brown, and like most fan shrimp its larvae need brackish water to develop, so it will not breed in a typical freshwater tank.

Care

Requires a mature tank with strong flow and suspended particulate food, hard-to-neutral water and stable GH for molting. Peaceful and plant-safe but a poor scavenger — target-feed powdered foods into the current if it hand-sifts the substrate. Copper-sensitive; use a lid.

Diet

Obligate filter feeder catching suspended micro-particles with fan-like appendages. Provide flow plus powdered or finely crushed foods and phytoplankton; hand-sifting the substrate signals it is not getting enough food.
