Decorator Crab

Description

Decorator Crab
The Decorator Crab is a fascinating invertebrate known for its unique camouflage behavior. Belonging to the spider crab family, it uses specialized hooked setae (hair-like structures) on its body to attach bits of algae, sponges, shells, and even corals to itself—blending perfectly into its surroundings. This natural disguise helps it avoid predators while also making it an intriguing addition to an aquarium.

Generally nocturnal, the Decorator Crab spends most of the day hiding and becomes more active at night while scavenging for food. It is considered a hardy species, feeding on detritus, algae, and leftover food, which can help keep the aquarium clean. However, some individuals may nip at corals or sessile invertebrates if hungry, so they are best suited for tanks with plenty of natural décor for them to use.

With its unusual appearance and clever decorating habits, the Decorator Crab is both a natural cleaner and a conversation starter in any marine setup.
