Flower Bamboo Shrimp Care Guide (Atyopsis moluccensis): Feeding a Filter-Feeder
The Flower Bamboo Shrimp (Atyopsis moluccensis), also called the wood shrimp or fan shrimp, is one of the most fascinating invertebrates in the hobby. Instead of scavenging, it perches in the current and opens fan-like appendages to strain food from the water. That unique feeding style is beautiful to watch, but it also means these shrimp have specific needs. This guide explains how to keep them well fed and healthy.

- pH: 6.5–7.5
- Temperament: peaceful, shy
- Diet: filter feeder (suspended particles)
- Lifespan: 1–2 years or more
The most important thing: water flow and food
Unlike cherry or amano shrimp, bamboo shrimp do not scavenge the substrate effectively. They rely on catching tiny food particles drifting in the current with their fans. This means two things: your tank needs decent water movement, and the water must actually contain fine food. A mature, established tank with some suspended organic matter suits them best. Position them where they can perch in the flow of a filter or powerhead outlet.
Feeding a filter feeder
Because they can slowly starve in a too-clean tank, you often need to feed them directly. Use powdered or finely crushed foods, such as crushed flakes, powdered fry food, or specialty filter-feeder foods, and gently squirt the food into the water column near the shrimp using a pipette or turkey baster. If you see a bamboo shrimp constantly picking at the substrate with its fans, that is a warning sign it is not catching enough food.
Tank setup
Provide a stable, cycled tank with good flow, hiding spots, and elevated perches like driftwood or hardscape near the current. Live plants improve water quality and add cover—browse live aquarium plants. Keep parameters stable, as these shrimp dislike sudden changes; regular small water changes help, and our water change guide covers the routine.
Behavior and molting
Bamboo shrimp are peaceful and often hide for a day or two after arriving or after molting. They change color over time and may appear reddish, brown, or tan. As with all shrimp, avoid copper-based medications, which are toxic to invertebrates. Stable water and good calcium levels support healthy molts.
Tank mates
Keep them with peaceful community fish and other calm invertebrates. Avoid large, aggressive, or shrimp-eating fish. They coexist well with small tetras, rasboras, corydoras, and snails.
