The Watchman Goby (Cryptocentrus cinctus) is best known for its symbiotic partnership with a pistol shrimp - the shrimp digs and maintains a shared burrow while the goby stands gua rd, flicking its tail to warn of danger. Peaceful and endlessly entertaining to watch, it's a reef-safe favorite even without a shrimp partner. Adult size: Around 3-4 in. Diet: Carnivore - meaty foods and sinking pellets. Temperament: Peaceful; pairs naturally with a pistol shrimp if one is present. Reef compatibility: Reef safe. Available for local pickup - in-store only. Stop by our shop in Wheeling, IL. Backed by expert support from real reefers at Marine Concept Supply. Show more
