The Spider Decorator Crab, also known as Camposcia retusa, is a fascinating and unique invertebrate that adds intrigue and character to marine aquariums. This small crab species is known for its ability to camouflage and decorate its exoskeleton with bits of algae, sponge, and other materials from its environment, resembling a spiky appearance.
 
The Spider Decorator Crab has a compact size, reaching an average size of about 1 inch across its carapace. It is relatively hardy and can adapt well to a variety of marine aquarium setups. However, it is important to provide them with plenty of hiding spots, rocks, and crevices to mimic their natural habitat.
 
These crabs are generally peaceful and can be kept with other small, non-aggressive marine species. However, caution should be exercised when keeping them with delicate or slow-moving invertebrates, as they may view them as potential prey.
 
Feeding the Spider Decorator Crab is relatively easy as they are opportunistic omnivores. They will eagerly consume a variety of meaty foods, such as small pieces of fish, shrimp, and crab pellets. Additionally, they may also graze on algae and detritus present in the aquarium.
 
The Spider Decorator Crab's unique characteristic lies in its ability to decorate its exoskeleton with various materials, enabling it to blend into its surroundings and offering an interesting sight for aquarium enthusiasts. This behavior adds an element of intrigue and natural beauty to the aquarium.
