What is harlequin shrimp?

Harlequin shrimp, also known as painted shrimp, are strikingly colored shrimp belonging to the genus Hymenocera. They are native to the Indo-Pacific region, including the waters of Indonesia, Australia, and the Philippines. Harlequin shrimp are popular in the aquarium trade due to their vibrant colors and unique appearance.

These shrimp have a distinctive color pattern, with bright orange, red, and white markings covering their bodies. They have a flattened body shape and large, brightly colored claws that they use to catch their prey.

Harlequin shrimp are specialized feeders, primarily preying on starfish. They are known for their ability to flip over large, armored starfish and feed on their tube feet. In aquariums, they are often fed frozen starfish arms or pieces of shrimp.

Harlequin shrimp are generally peaceful creatures, but they can be territorial and may become aggressive towards other shrimp or small invertebrates in their tank. They require a well-established aquarium with plenty of hiding spots and live rock to create a suitable environment for them to thrive.

These shrimp are relatively small, growing to a maximum size of about 2 inches in length. They have a relatively long lifespan, with some individuals living up to 5 years in captivity.

Overall, harlequin shrimp are a unique and visually striking addition to a saltwater aquarium, but they require specialized care and attention to ensure their well-being.
