Pistol Shrimp

Common Name(s): Pistol Shrimp

The name Symbiotic Shrimp comes from the equally beneficial relationship the Pistol Shrimp has with gobies (e.g.;Amblyeleotris or Stonogobiops). The goby, with better eyesight, warns the shrimp of predators. The shrimp share its food with the goby. Depending upon the species, Pistol Shrimp may also have symbiotic relationships with sponges, corals, or anemones (e.g.; Bartholomea annulata).

It is beneficial to the tank as it churns the sand. It thrives in environments with sand, rock caves, and dim light. If in pairs, one will often stand guard at the burrow while the other is inside.

Other Comments: The Pistol Shrimp may also be called Symbiosis Shrimp and Snapping Shrimp. It is found in a variety of colors and sizes. Pistol Shrimp are not easily sexed, but the males of many species are thought to have a larger pincer. The sound it makes comes from an appendage on the pincer which moves when the pincer is opened or closed and water is ejected. The Pistol Shrimp can be easily confused with Mantis Shrimp if judged by sound only. Unlike the Mantis Shrimp, it is not harmful and will not pose any threat in the tank, with the possible exception of smaller shrimp.
