Pistol Shrimp (Maldives)

 Introducing the pistol shrimp, nature's tiny powerhouse with a punch that packs more heat than a spicy jalapeño on a summer day. This pint-sized pistolero is armed with a claw that could give Wolverine's retractable blades a run for their money. With a snap faster than a New York minute, this shrimp creates a cavitation bubble hotter than a Hollywood scandal, stunning prey with the force of a tiny aquatic shockwave. Call it the Clint Eastwood of the ocean, because when this shrimp draws, even the biggest fish better watch their tails.

They are great for any aquarium and have a symbiotic relationship with gobies. 

Invertebrates can be more sensitive to parameter changes than fish or coral.  High nitrate levels or sudden changes in pH or Salinity can be very harmful to inverts and may cause death.  It is recommended to do a slow acclimation process when adding new inverts to your aquarium.
