Common name: red snapping shrimp

General information

The Tiger Pistol Shrimp, scientifically known as Alpheus bisincisus, is a fascinating marine invertebrate known for its symbiotic relationships and its unique ability to produce a loud snapping sound. This sound is generated by the rapid closing of its specialized claw, which can also create shockwaves to stun prey or deter predators.

Care

Tiger Pistol Shrimp are relatively hardy and can be kept in aquariums with stable water conditions. They require a sandy substrate to construct burrows and appreciate the presence of live rock for additional hiding places. Care should be taken to ensure that tank mates are compatible, as these shrimps can be territorial.

Reproduction

In the aquarium, Tiger Pistol Shrimp may breed if a male and female pair is established. The female carries the eggs until they hatch, releasing planktonic larvae into the water column.

Symbiosis

One of the most notable behaviors of Alpheus bisincisus is its symbiotic relationship with certain species of gobies, particularly those in the genus Cryptocentrus. The shrimp maintains a shared burrow which both the goby and shrimp inhabit. The goby acts as a lookout, warning the shrimp of approaching danger, while the shrimp provides a safe home.

Habitat

Tiger Pistol Shrimp are found in the Indo-Pacific region, from the eastern coast of Africa to the western Pacific. They typically inhabit shallow waters, often associating with coral reefs where they can find suitable substrates for burrowing.
