Aquarium Advice Addict
any one have any info?
Pistol Shrimp (Alpheus spp.) Also known as Click Shrimp, Popping Shrimp and Snapping Shrimp. These animals snap shut their enlarged claw to generate a loud click which in an aquarium sounds something like a marble being thrown at the glass! They are generally considered peaceful tankmates if you can put up with the noise which is at its worst in the dead of night.
