The Decorator Crab, also known as Camposcia Decorator Crab or Spider Decorator Crab, is a member of the Majidae family of spider and decorator crabs. It decorates its brown body with sponges, shells, rocks, and other items as a method of camouflage.
It is nocturnal, hunting at night. It is not reef compatible, eating some invertebrates. It may be harmful, as well, as it harvests algae, soft corals, and invertebrates to adorn its shell.
The diet of the Decorator Crab should include meaty foods such as chopped fish and clams.
