BAMBOO / WOOD shrimp (Atyopsis moluccensis) is a freshwater Shrimp native to southeast Asia. This species has no documented history of introduction despite its use in the aquarium trade in the United States, Europe, and Asia. Holding of WOOD shrimp has become very popular in the uk. They are also called many different names such as Fan Shrimp, Filter Shrimp, Asian Filter Shrimp, Wood Shrimp, Timber Shrimp, Singapore Shrimp, Marble Shrimp, Mountain Shrimp, Rock Shrimp, Maluku Shrimp, and Flower Shrimp. 
WOOD shrimp is probably one of the most strange and interesting shrimp in this hobby. Despite their impressive size, they are very peaceful and quiet. They are gentle giants which do not care about anything but the flow. Their color is relatively variable. WOOD shrimp can be easily kept with other dwarf shrimp, snails, or non-aggressive fish in the aquarium. 
One of the unique features of Bamboo shrimp is that these harmless giants have four pairs of fans (instead of claws) which they use to capture and filter the micro-particles of food in the water and then take them to the mouth.
WOOD shrimp have a large creamy yellow-brown (reddish-brown or light to dark brown) race stripe down their back. This back stripe is particularly pronounced in the younger shrimp, weaker in older specimens, but never completely disappears. In addition, some shrimp also have dark side stripes. The patterns are effective camouflage to human eyes, that is why a lot of shrimp keepers “lose” these giants in their tanks.
Also, larger specimens tend to be a little darker than smaller ones.
