Valencienna longipinnis. VALENCIENNA WARDI. The Tiger Watchman Goby is also known as the Ward's Sleeper, Ward's Tiger, or Tiger Sleeper Goby. It has a white body with brown bands, and an eyespot on the first dorsal fin. It should be housed in a 30 gallon or larger aquarium with live sand as the substrate, and an attached populated refugium. It will rarely become aggressive towards other fish, but it is territorial, and will fight with its own kind unless they are a male-female pair. Usually the Tiger Watchman Goby will feed off the bottom sifting through the sand. The diet should consist of a variety of live and frozen brine shrimp, mysis shrimp, live black worms, and prepared foods for carnivores. It should be fed frequently.
