Camposcia retusa

Datasheet

General Description

The Decorator Crab, scientifically known as Camposcia retusa, belongs to the Majoidea family Camposcia. These crabs are known for their peculiar habit of decorating themselves with materials such as soft coral, rocks, algae, or similar items, occasionally even consuming the soft coral. They can grow up to 10.0cm in size and are primarily found in the East Indian Ocean, particularly in Indonesia.

Aquarium Suitability

Considered suitable with care, Decorator Crabs are known for their hardiness. While some individuals may struggle with acclimatization in an aquarium setting, others prove to be problem-free. They require a minimum tank size of 100 liters and are nocturnal creatures, most active when the lighting is dimmed or turned off.

Care and Hardiness

Decorator Crabs are classified as hardy creatures, thriving in water conditions with a pH range of 8.1-8.4, a specific gravity of 1.020-1.025, and a temperature between 22.2-25.6°C. They prefer alkaline water with a carbonate hardness level of 8-12.

Reef Suitability

Reef aquarists can consider Decorator Crabs as reef safe with caution, as these crabs have the potential to cut soft corals for their decoration needs. It is essential to monitor their interactions with coral and other reef inhabitants closely.

Aquarium Setup

For a suitable aquarium setup for Decorator Crabs, provide ample hiding spots with rocks, caves, and crevices. Ensure the tank has subdued lighting to accommodate their nocturnal behavior. Maintain stable water parameters to support their overall health and well-being.

Behaviour

The temperament of Decorator Crabs is relatively unknown, but they are generally more active during the night. They may display territorial behavior if housed with other tank mates, especially if resources are limited.

Feeding and Diet

These crabs are omnivores and should be provided with a varied diet. Their recommended diet includes fish, larger crustaceans like shrimp and crabs, other invertebrates, and small crustaceans such as krill, mysis, and artemia. Offering a diverse diet will help ensure their nutritional needs are met in captivity.

Habitat and Distribution

Decorator Crabs, specifically Camposcia retusa, are primarily found in the East Indian Ocean, particularly in Indonesia. They inhabit shallow coastal waters and are often associated with areas rich in soft corals and algae, which they use for decoration and camouflage. In aquarium settings, mimicking their natural habitat through appropriate decor and substrate can enhance their overall well-being.
