Cryptocentrus cinctus

The Yellow Dotted Watchman Goby, also known as the Yellow Watchman or Yellow Prawn Goby, is a hardy, personable bottom-dweller ideal for both beginner and advanced reefkeepers. Its bright yellow body—often dusted with iridescent blue or white spots—adds a splash of color to lower zones of the aquarium. Known for forming symbiotic relationships with pistol shrimp, this goby creates engaging behavior displays that boost retail tank interaction and appeal.
