Yellow Watchman Goby


These fish have a striking yellow colour with blue dots over the upper part of their body. They need a sand bed with plenty of hiding spaces. Like all Gobies they will sift through the sand bed looking for food and often make burrows to live in. They often form symbiotic relationships with the pistol shrimp where they will both live in the same burrow.



I have recently just got a goby and pistol shrimp and they have literally changed the landscape of my sand bed over night. Although I don’t see them often (as they tend to hid under the rock work) every morning there is a fresh mound of clean sand near their tunnel.

I spend a lot of my time wondering if they are still alive as I don’t see them often. It has almost become a game to snap a photo of them before they go and hide again.



Tank Size

A 30 gallon aquarium is need for the watchman goby. They will also need a sand bed deep enough to create tunnels to hide in. These fish do well in a communal tank. However it would be cruel to house the watchman goby in a bare bottom aquarium as it is their nature to dig and sift sand.


Care Level

Easy – But like most gobies they jumpers. Over the years I have lost two gobies that have jumped out of smallest feeding hole in the lid. I fully recommend if you want a goby or any sorts that you have a lid on your aquarium.



Peaceful – They tend to stay out of the way of other fish and avoid conflict. Although if paired off with a pistol shrimp, the shrimp will defend the goby and its tunnel.



Reef Safe

Yes – However it may dig under rocks and cause them to fall. As a result of this the rock formation needs to be secure to prevent the goby getting squashed. Any corals placed on the sand bed may also become covered in sand as the goby works through your sand bed.


Max Size

3 inches



The head and body has a bright yellow/orange color with bright blue dots across its head and fins.



The Yellow Watchman Gobies diet should include a variety of mysis shrimp, brine shrimp, table shrimp, and frozen preparations for carnivores. They will also feed on pods and critters that live within the sand bed.
