Description: The color of the African Giant Filter Shrimp can vary from a creamy white to rusty brown, while there is also a blue color variant. Some say that water conditions may affect their body colors and harder water causes the blue morph. Despite their size and look they are harmless species and will not hurt even the smallest fry or other, smaller shrimp, so they can be housed in the same tank. Interestingly they have feathery bristles on their first 2 legs which can be opened like fans, and with these fans they can filter the water for food particles. During daytime they usually hide in caves, often several shrimp occupy the same shelter, and they rather prefer tight fit caves. Like many invertebrates, fan shrimps are very sensitive to copper that is found in many fish medication, and they also sensitive to ammonia and nitrite. This is a rarely seen species in the hobby, most of them found at the stores are wild caught.

It is almost impossible to distinguish the sexes, and their breeding is very rare in aquarium. Brackish water or saltwater is required to raise the newly hatched larvae. The young exist in a drifting, planktonic state before changing into a miniature adult-like form after several molts.
