Yellow Watchmen Gobies are a popular saltwater fish known for their vibrant yellow coloration and charming personalities. These gobies are typically found in the sandy bottoms and rocky crevices of reef environments, and require a specific salinity range of 1.020-1.025.
 
These gobies are relatively small, growing up to 3 inches in size, and have a bright yellow body with a white or black head. They are peaceful and generally do not exhibit aggressive behavior towards other fish in the tank, making them a great addition to a community tank.
 
To ensure optimal health and happiness, Yellow Watchmen Gobies require a minimum tank size of 20 gallons with a well-maintained filtration system. They prefer live rock and sand to hide and explore, and a diet of small meaty foods, such as brine shrimp, mysis shrimp, and other small crustaceans.
 
One unique trait of Yellow Watchmen Gobies is their symbiotic relationship with pistol shrimp. These two species form a mutualistic bond where the goby acts as a lookout for the shrimp, and the shrimp provides a safe burrow for the goby to hide in.
