Spider (Decorator) Crab

Camposcia retusa

Identification	Long spidery legs with a small central body. Covers itself in algae, sponges, bryozoans, and other marine organisms as camouflage, making its appearance unique and constantly changing.
Maximum Length	5 inches leg span
Origin	Indo-Pacific
Minimum Tank Size	30 gallons
Reef Compatibility	With caution

Behavior

Nocturnal and secretive. The behavioral adaptation of adorning itself with living organisms for camouflage is fascinating to observe. Rarely seen during the day.

Diet & Feeding

Omnivore. Scavenges for algae, organic debris, and small invertebrates. Also harvests materials from the tank for decoration.

Cautions

Will harvest and attach small pieces of coral, sponge, and macroalgae to its body, potentially damaging corals in the process. Not ideal for tanks with valuable coral specimens.
