Common name: Decorator Crabs

Inachidae, commonly known as Decorator Crabs, is a family of crabs known for their unique behavior of attaching materials like algae, sponges, and other debris to their bodies for camouflage. This behavior not only helps them blend into their environment to avoid predators but also sometimes provides additional benefits like food from the algae they carry. In the aquarium, they can be fascinating to observe and can help control algae growth. However, they may also decorate themselves with corals and other invertebrates, which can be detrimental to a reef tank if not monitored.
