Common name: Spotted Porcelain Crab

General information

The Spotted Porcelain Crab, scientifically known as Neopetrolisthes maculatus, is a small and colorful crustacean popular among reef aquarium enthusiasts. It is known for its striking pattern of spots and its flat, round body which is well-adapted for living in tight spaces within the reef. These crabs are peaceful and can be a great addition to a community tank.

Care

Spotted Porcelain Crabs are relatively easy to care for. They require a tank with plenty of live rock and hiding places to feel secure. They are filter feeders, using their specialized appendages to capture food particles from the water column, so a tank with a moderate current is beneficial to mimic their natural feeding behavior.

Reproduction

In the aquarium, Spotted Porcelain Crabs can reproduce if conditions are right. The female carries the eggs under her abdomen until they hatch into larvae. The larvae go through several planktonic stages before settling down and developing into juvenile crabs.

Symbiosis

One of the most interesting aspects of Neopetrolisthes maculatus is its symbiotic relationship with sea anemones. Similar to clownfish, these crabs live among the tentacles of anemones, gaining protection from predators. They are often associated with the carpet anemone @species:stichodactyla-haddoni and the giant anemone @species:stichodactyla-gigantea. The crab benefits from the anemone's protection, while the anemone may receive food scraps from the crab's filter feeding.

Habitat

Spotted Porcelain Crabs are found in the Indo-Pacific region, from the Red Sea and East Africa to the central Pacific. They typically inhabit coral reefs and are often seen in association with anemones at depths ranging from shallow waters to about 40 meters deep.
