General information

The Boxer Crab, also known as the Pom-Pom Crab, is a fascinating small crustacean known for its unique symbiotic relationship with sea anemones. It belongs to the species Phyllognathia ceratophthalma and is a member of the family Galatheidae. These crabs are known for their distinctive behavior of carrying small sea anemones in their claws, which resemble cheerleader pom-poms, hence the name.

Care

Boxer Crabs are small and relatively easy to care for in a well-established reef aquarium. They require stable water conditions and plenty of hiding places. They are peaceful and can be kept with other non-aggressive tank mates. It's important to provide a varied diet that includes meaty foods and detritus to mimic their natural scavenging behavior.

Reproduction

In the wild, Boxer Crabs are known to reproduce by releasing larvae into the water column. In captivity, breeding is less common, but with optimal conditions, it is possible to observe their reproductive behavior. The larvae will need to be reared in a separate tank with appropriate food and conditions.

Symbiosis

The most notable aspect of the Boxer Crab is its symbiotic relationship with sea anemones. The crab holds a small anemone in each claw, which it uses for defense and to capture food. In return, the anemones benefit from increased mobility and access to food particles as the crab moves around.

Habitat

Boxer Crabs are found in the Indo-Pacific region, typically in shallow reef environments. They often inhabit coral rubble and areas with plenty of crevices for shelter.
