Pistol Shrimp, commonly referred to as Alpheidae, are a fascinating group of crustaceans known for their unique and powerful snapping abilities. One well-known example is the Pistol Shrimp and Goby symbiotic relationship, where the shrimp and goby share a burrow. Here are some details:

  • Lifespan: Typically a few years.



  • Distinctive snapping claw, used for hunting and communication.
  • Various colors and patterns depending on the species.



  • Found in various marine environments, from coral reefs to sandy substrates.



  • Known for their symbiotic relationships, particularly with certain species of gobies.
  • The snapping claw creates a shockwave and cavitation bubble, stunning or killing prey.


Tank Size:

  • Depends on the specific species. Smaller species can be kept in smaller marine tanks.


Care Level:

  • Moderate to Advanced.
  • Requires appropriate marine conditions and hiding spots.



  • Omnivorous. Feeds on small invertebrates and organic debris.


Water Parameters:

  • pH: 8.0-8.4
