Pink Spotted Watchman Goby (Cryptocentrus leptocephalus) Add a dedicated sand-sifting worker and a burst of unique color to your aquarium's lower levels. The Pink Spotted Watchman Goby features a beautiful, pearlescent pink-to-tan body covered in hundreds of shimmering pink, orange, and neon blue spots. Famous for its perpetual, grumpy-looking facial expression, this industrious fish is highly prized for its relentless habit of cleaning the substrate, making it a stellar addition to any marine clean-up crew. Incredibly hardy, full of attitude, and simple to care for, this goby brings continuous substrate-level movement and a fascinating personality to the home reef. Quick Care Specifications Care Level: Easy Temperament: Peaceful (Territorial toward other bottom-dwellers) Maximum Size: 5 to 6 inches in captivity Minimum Tank Size: 30+ Gallons Reef Compatibility: 100% Reef-Safe (Completely safe for corals and invertebrates) Water Parameters: 72–78°F, pH 8.1–8.4, dKH 8–12, Salinity 1.020–1.025 SG Key Features & Tank Requirements 🚜 Natural Sand-Sifting Utility A relentless substrate cleaner. This goby loves to scoop up mouthfuls of sand, filter out organic debris and micro-fauna, and expel clean sand through its gills. This natural behavior prevents detritus buildup and keeps your sandbed looking pristine. 🦐 Pistol Shrimp Symbiosis Like many watchman gobies, this species can form a spectacular, lifelong symbiotic relationship with Alpheus genus Pistol Shrimp (such as the Tiger Pistol Shrimp). The shrimp constructs and maintains a clean burrow for both of them, while the sharp-eyed goby acts as a sentry, guarding the entrance and flashing its fins to warn the near-blind shrimp of danger. ⏳ Thick Sandbed & Rubble Required To support its burrowing habits, your aquarium must feature a sandbed at least 2–3 inches deep. Providing loose coral rubble and empty shells near the base of your live rock gives the goby and its shrimp partner the perfect construction materials to reinforce their underground home. 🍖 Hardy, Unfussy Carnivore An opportunistic bottom-feeder with an excellent appetite. They eagerly accept a wide variety of meaty foods, including frozen mysis shrimp, enriched brine shrimp, chopped krill, table shrimp, and high-quality sinking carnivore pellets. 👥 Substrate-Level Territoriality Wonderfully peaceful toward all open-water swimmers, corals, and ornamental invertebrates. However, they can be highly aggressive toward their own kind or other bottom-dwelling gobies unless housed in a massive aquarium. Keep them singly, or as a verified, established pair.
