This member of the porcelain crabs will generally stay in a rocky crevasse , among sponges and even in clumps of algae. They use sweeping, feathery arms to catch diatoms and other microplankton. Tolerant of other Porcelain crabs, they should not be kept with any larger crabs. If they are threatened, they may drop a claw or leg to escape, regrowing the leg on the next molt.
