The Porcelain is a tropical crab that has a flat, round body with two front claws and two feather duster arms (maximillipeds). They use these arms to filter feed but will also eat other meaty foods added to the tank. This particular crab is reef safe and often hides under rocks and inside of caves. They work well in pairs and live peacefully in a marine aquarium. This particular Porcelain is referred to as a Caribbean Porcelain. There is also an Anenome Poreclain Crab which is white with darker spots and is less reclusive.
