The Yellow Watchman Goby, scientifically known as Cryptocentrus cinctus, is a popular and charming saltwater aquarium fish known for its vibrant coloration and engaging behavior. Here are some key features and care guidelines for the Yellow Watchman Goby:

1. **Appearance:** As the name suggests, the Yellow Watchman Goby displays a bright yellow body with distinct blue markings on its head and a black "eyelike" spot on its dorsal fin. This fish has a slender body and can grow up to 3 inches (7.5 cm) in length.

2. **Behavior:** Yellow Watchman Gobies are known for their interesting and symbiotic relationship with pistol shrimp. They share a burrow with these shrimp, and the goby acts as a lookout guard while the shrimp maintains and excavates the burrow. This cooperation benefits both species, making them a fascinating addition to a reef aquarium.

3. **Tank Setup:** To create an ideal environment for Yellow Watchman Gobies, provide a well-established marine aquarium with live rock and sand substrate. These gobies are burrowers, so ensure there is ample sandy substrate for them to dig and build burrows. The tank should have hiding places and crevices where they can retreat when feeling threatened.

4. **Feeding:** Yellow Watchman Gobies are carnivorous and primarily feed on small invertebrates, zooplankton, and tiny crustaceans in the wild. In captivity, they readily accept high-quality frozen and live foods such as brine shrimp, mysis shrimp, and small pieces of marine fish. Offering a varied diet is essential for their health.

5. **Compatibility:** These gobies are generally peaceful and get along well with other non-aggressive tankmates. They can coexist with a variety of reef-safe fish and invertebrates, making them a suitable addition to a community reef tank.

6. **Water Parameters:** Maintain stable water parameters with a temperature range of 75°F to 80°F (24°C to 27°C), a pH level of 8.1 to 8.4, and a specific gravity of 1.020 to 1.025. Regular water changes are essential to ensure water quality remains optimal.

7. **Breeding:** Breeding Yellow Watchman Gobies in captivity can be challenging due to their symbiotic relationship with pistol shrimp. In the wild, these gobies lay their eggs in the burrow, and the shrimp guard and aerate them. Replicating this behavior in a home aquarium can be complex.

The Yellow Watchman Goby's vibrant appearance and fascinating behavior make it a sought-after choice for marine aquarium enthusiasts. Their unique partnership with pistol shrimp adds an extra layer of intrigue to any reef tank. Providing them with a suitable environment, including sand for burrowing, and a well-balanced diet will help ensure their health and longevity in captivity.
