Common name: Anker's Pistol Shrimp

General information

Anker's Pistol Shrimp, scientifically known as Lysmata ankeri, is a captivating species for many aquarists due to its unique behavior and striking appearance. This species is characterized by its asymmetrical claws; the larger claw can produce a loud snapping sound used for communication and defense. The shrimp's body is typically translucent with a pattern of red and white stripes, making it a visually appealing addition to the reef aquarium.

Care

Lysmata ankeri is a hardy species that can adapt to a range of conditions found in captive environments. They require a tank with plenty of live rock and hiding places to feel secure. A sand substrate is also beneficial as they often burrow. They are scavengers by nature, feeding on detritus, leftover food, and small pests, which helps maintain tank cleanliness.

Reproduction

Pistol Shrimp are protandric simultaneous hermaphrodites, meaning they possess both male and female reproductive organs and can change sex throughout their life. They can reproduce in the aquarium if kept in a group, with one individual typically assuming a more dominant role during breeding.

Symbiosis

Anker's Pistol Shrimp are known for their fascinating symbiotic relationship with certain species of gobies, such as the @species:stonogobiops-nemateleotris. The shrimp maintains a burrow in the sand which both the shrimp and goby inhabit. The goby acts as a lookout for predators while the shrimp works on the burrow. This mutualistic relationship provides safety for both parties.

Habitat

This species is found in the tropical Western Atlantic, including the Caribbean Sea and the Gulf of Mexico. They inhabit shallow reef environments, often associating with sandy bottoms and rubble areas where they can create their burrows.
