Common name: Immaculate Pistol Shrimp

General information

The Immaculate Pistol Shrimp, Alpheus immaculatus, is a fascinating marine invertebrate known for its distinctive snapping claw. This species is relatively small, usually not exceeding 5 centimeters in length. The shrimp is named for its immaculate appearance, characterized by a translucent body with white spots and sometimes light brown bands. The most notable feature is the large snapping claw, which the shrimp uses for defense and to stun prey.

Care

Immaculate Pistol Shrimp are generally hardy and can be a great addition to a reef or fish-only aquarium. They require a tank with plenty of live rock and a sandy substrate to create burrows. These shrimps are known to be reclusive, so providing hiding places is essential for their well-being. They are not picky eaters and will accept a variety of foods, including frozen and pellet feeds.

Reproduction

In the aquarium, Alpheus immaculatus may breed if a pair is established. The female carries the eggs until they hatch into free-swimming larvae. Raising the larvae to adulthood can be challenging due to their planktonic nature and the need for very fine foods.

Symbiosis

One of the most interesting aspects of the Immaculate Pistol Shrimp is its symbiotic relationship with certain species of gobies, particularly those in the genus Cryptocentrus and Stonogobiops. The shrimp and goby share a burrow, with the goby acting as a lookout while the shrimp maintains the structure. This mutualistic relationship provides the shrimp with a warning system against predators, while the goby gains a safe home.

Habitat

Alpheus immaculatus is typically found in shallow tropical marine environments, often in association with coral reefs. They are distributed across the Indo-Pacific region, from the eastern coast of Africa to the central Pacific Ocean.
