Common name: Harlequin Shrimp

General information

The Harlequin Shrimp, scientifically known as Periclimenes lanipes, is a captivating species of shrimp that is highly sought after by marine aquarium enthusiasts for its striking appearance and unique behaviors. This species is characterized by its vibrant coloration, typically a bright white body with large, conspicuous red or purple spots. The Harlequin Shrimp is relatively small, reaching only about 5 centimeters in length, making it a suitable inhabitant for smaller reef aquariums as well.

Care

Harlequin Shrimps require a well-established aquarium with stable water conditions and plenty of live rock for hiding and foraging. They are sensitive to changes in water quality, so regular maintenance and water testing are crucial. These shrimps are carnivorous and have a specialized diet, primarily feeding on starfish, including the Asterina species, which can be provided as food in captivity. Due to their specific dietary needs, they may not be suitable for all reef aquariums, especially those containing valuable starfish species.

Reproduction

In the aquarium, Harlequin Shrimps can reproduce if provided with the right conditions. They are known to form monogamous pairs, and the female carries the eggs until they hatch. The larvae are planktonic and can be challenging to raise in captivity, requiring microscopic foods such as phytoplankton or rotifers.

Symbiosis

While not known for a specific symbiotic relationship like clownfish and anemones, Harlequin Shrimps do contribute to the reef ecosystem by controlling populations of starfish, some of which can become pests in both natural and artificial environments.

Habitat

Periclimenes lanipes is found in the tropical waters of the Indo-Pacific region, from the Red Sea and East Africa to the central Pacific. They typically inhabit coral reefs and are often associated with crevices and the undersides of rocks, where they can hunt for starfish and avoid predators.
