Origin[edit | edit source]

Western Pacific: Indonesia to New Caledonia, north to the Yaeyama Islands, south to northwestern Australia.


Sexing[edit | edit source]

Difficult to visually sex.


Tank compatibility[edit | edit source]

Generally peaceful towards other fish and reef-safe. However, it is territorial to its own and similar species unless they are a mated pair. Unless they are a proven pair, keep one Goby to a tank.


Diet[edit | edit source]

Will accept most meaty foods including mysis shrimp, enriched brine shrimp and sinking pellet food.


Feeding regime[edit | edit source]

Feed at least twice a day.


Environment specifics[edit | edit source]

Should be in a mature tank with a deep loose coral gravel substrate. It also requires ample swimming room and a secure lid as this fish is an excellent escape artist.


Behaviour[edit | edit source]

A peaceful, but territorial, bottom-dwelling and burrowing Goby. This Goby is known to be one of the watchman family that will share it's burrow with a pistol shrimp. It is the shrimp that does the digging for the Goby while the Goby is the lookout, hence being the watchman. Whenever the shrimp is out of the burrow, he always keeps one antennae on the Goby and retreats quickly back to the burrow if the fish swishes his tail. They built several burrows around the tank before finally settling down. The burrow is quite elaborate as they gathered many pieces of rock rubble to create their home. At night, the Spotted Watchman Goby closes the burrow off with the larger piece of rock, there is absolutely no evidence that it exists, unless you know the rock is covering a hole. In the morning, the Spotted Watchman Goby shoves the rock back out of the way and spends the majority of his time sitting outside the burrow. When the tank is fed, the goby brings food to the shrimp.


Identification[edit | edit source]

Typical Goby in shape. The body is pale in colour with dark grey vertical banding that vary fish to fish on how strong in colour they are, in some fish they're almost invisible. The head and body are covered with pink spots surrounded by smaller blue spots.
