Harlequin Shrimp

Harlequin Shrimp are obligate starfish predators and will only consume starfish species, making them one of the most specialized feeders in the aquarium hobby. Feed small starfish (such as Linckia or Fromia species) 2-3 times per week, allowing the pair to hunt and consume them naturally. This dietary requirement is non-negotiable and makes them unsuitable for most reef aquariums where starfish are valued.

These shrimp are peaceful, slow-moving hunters that spend most of their time searching the substrate and rockwork for starfish prey. They are best kept in pairs or small groups and exhibit fascinating cooperative hunting behavior, often working together to subdue larger starfish. They are nocturnal to crepuscular and may hide during bright lighting periods.

Breeding Harlequin Shrimp in captivity is extremely rare and poorly documented, with most captive specimens being wild-caught. Females produce planktonic larvae that are difficult to rear without specialized larval food and conditions. Successful breeding requires pristine water quality, stable temperatures, and abundant live starfish food sources.
