The Yellow Watchman Goby is also known as the Yellow Watchman Prawn, or Yellow Shrimp Goby, was first discovered in 1936 by Herre. The head and body are yellow-orange with bright blue spots on the head and fins. The Yellow Watchman Goby wears an amusing perpetual frown, and likes to peek out from behind rocks. They have been known to form symbiotic relationships with pistol shrimp.
It requires a 10 gallon or larger aquarium with plenty of loose coral rubble, ample swimming room, and a sand bottom for burrowing. It rarely becomes aggressive towards other fish, but it is territorial, and will fight with its own kind unless they are a mated pair. It may try to jump out of the aquarium or other small openings, therefore, a tight-fitting lid is required to prevent escape.
The Yellow Watchman Goby diet should include a variety of mysis shrimp, brine shrimp, table shrimp, and frozen preparations for carnivores. It should be fed at least twice per day.
