Spider Decorator Crab
The Spider Decorator Crab, also known as Camposcia Decorator Crab or 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. In the reef aquarium, it harvests algae, soft corals, and invertebrates to adorn its shell. This activity may cause harm to some soft corals, but in the large reef aquarium, this activity actually helps spread and propagate these same corals throughout the aquarium.
The diet of the Spider Decorator Crab should include meaty foods such as chopped fish and clams.

The crab is active at night and adds interesting visual elements to the tank. I noticed it collecting small pieces of coral and rock, which seems to help distribute them across the reef. Feeding it chopped fish works well. It’s a unique addition to my reef setup.

It’s a fascinating creature that changes its appearance regularly. I had some concern about it damaging corals, but after a few weeks, I saw more coral growth in areas it visited. It’s not aggressive and seems to enjoy its environment.

Great for a reef tank with a natural look. The crab decorates its shell with rocks and sponges, making the tank more dynamic. It’s active at night and doesn’t seem to harm the existing corals. Easy to care for with regular meaty feedings.
