The OS Watchman (Amblyeleotris guttata) is a peaceful, hardy fish that should be housed in a 30+ gallon tank with a sandy bottom. They will use bits of rubble to help them build a burrow in the sand. If present, Watchman Gobies will form a symbiotic relationship with certain Pistol Snapping Shrimp. The Goby, using its superior vision, watches for potential threats and warms the shrimp if it needs to retreat into the burrow. The shrimp builds and maintains the burrow. Orange Spot Watchman Gobies are found singly or in pairs in the wild. They will not nip at corals, and should be offered mysis and brine shrimp, pellet, and other prepared foods to supplement their diet. They are also "jumpers" so a tight fitting lid is a must. These fish reach a maximum size of roughly 4".
