Common name: Red-spotted Pistol Shrimp

General information

The Red-spotted Pistol Shrimp, Alpheus rubromaculatus, is a fascinating species known for its distinctive snapping claw. This claw can produce a loud snapping sound and a powerful jet of water, which is used for both hunting and defense. These shrimps are relatively small, usually not exceeding 5 centimeters in length, and are characterized by their striking red spots on a translucent body, making them a visually appealing addition to any reef aquarium.

Care

Caring for Red-spotted Pistol Shrimp requires a tank with plenty of live rock and a sandy substrate to allow for burrowing. They are generally peaceful but can be territorial with their own kind. It's important to provide them with a stable environment and avoid housing them with large, aggressive fish that may see them as prey. They will feed on a variety of foods, including frozen and pellet foods, but also appreciate the occasional meaty treat.

Reproduction

In the aquarium, reproduction of Alpheus rubromaculatus can occur if a male and female pair is established. They engage in a courtship ritual before the female lays eggs, which she carries until they hatch. The larvae go through several planktonic stages before settling down and morphing into miniature versions of the adults.

Symbiosis

One of the most interesting aspects of the Red-spotted Pistol Shrimp is its symbiotic relationship with certain species of gobies, particularly those in the genus Cryptocentrus. The shrimp and goby share a burrow, which the shrimp maintains while the goby stands guard. This mutualistic relationship provides the shrimp with protection while the goby gains a safe home.

Habitat

Alpheus rubromaculatus is typically found in shallow, tropical marine environments, often in association with coral reefs. They prefer areas with sandy substrates where they can create burrows.
