The Yellow watchman goby, also known as the yellow prawn goby has a yellow head and body sporting bright blue spots on their head and fins.
The 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.
They require a 30 gallon or larger aquarium with plenty of loose coral rubble, ample swimming room, and a sand bottom for burrowing.
Its rarely aggressive towards other fish, but it can be territorial, and can fight with its own kind unless they are a mated pair.
They have been known to jump out of the aquarium or other small openings so therefore a tightly fitted lid is required to prevent escape.
The Yellow watchman goby's 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.
