The Porcelain Anemone Crab is a small and colorful crab that is commonly found living in symbiotic relationships with sea anemones in the wild. They require a saltwater aquarium with a salinity level of 1.020-1.025 and are a popular addition to many reef aquariums.
 
Porcelain Anemone Crabs are relatively easy to care for and can thrive in a tank of at least 10 gallons. They are omnivores and will eat anything they can find, including small pieces of fish and shrimp, as well as algae and other plant material.
 
These crabs are small, growing up to only 1 inch in size, and are generally peaceful towards other fish and invertebrates. However, they may become territorial towards other crabs of the same species or towards other small creatures that may compete for resources.
 
In terms of tank decoration, Porcelain Anemone Crabs require a live anemone or a suitable substitute, such as a coral or artificial anemone. They are active during the day and will spend their time exploring their environment and feeding on the anemone's tentacles.
