The sound it makes comes from an appendage on the pincher which moves when the pincher is opened or closed and water is ejected. The Snapping 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 very small 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.
Tiger Snapping Shrimp thrive 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. The Pistol Shrimp are intolerant of copper or high nitrate levels, but need a correct level of iodine in the water to promote proper molting.
Snapping Shrimp will accept any meaty freeze-dried and frozen foods and bottom feeder tablets.
