The Porcelain Crab is a common invertebrate found in tropical oceans worldwide. It has a round, flat body and two large front claws, along with feather-like maxillipeds used to filter food from the water. These peaceful creatures make interesting additions to marine aquariums. In nature, Porcelain Crabs live in pairs and can be found under rocks. In captivity, they require plenty of live rock for hiding and feeding, and should not be kept with any fish or invertebrates that may harm them. They are safe to keep with other corals and invertebrates. Porcelain Crabs filter planktonic food from the water and scavenge for larger meaty portions. Feed them small bits of fish, shrimp, or other meaty foods, as well as foods designed for filter feeders.
