Common name: Shrimp Goby

Cryptocentrus, commonly known as Shrimp Gobies or Watchman Gobies, are a genus of gobies that form fascinating symbiotic relationships with pistol shrimps. These gobies act as sentinels for their burrowing crustacean partners, warning them of danger. They are popular in the reefkeeping hobby for their interesting behaviors and relatively easy care. They come in various colors and patterns, adding both visual appeal and activity to the tank. Hobbyists appreciate their role in the tank's micro-ecosystem, often observing the mutualistic partnership in action.
