Tank compatibility[edit]

A generally peaceful Goby that will only be territorial to its burrow. A Yellow Watchman will develop a symbiotic relationship with many pistol shrimp. If kept with very boisterous fish it will spend most of its time hidden.


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

Feeding regime[edit]

This fish can be shy, so if more boisterous fish are in the same environment, it may need to be target fed. May be difficult to feed when it's new to the tank, but will gradually become more bold.

Environment specifics[edit]

The Yellow Watchman Goby is a burrowing fish so therefore requires a coarse sand substrate and all décor must be secure to avoid any accidents.


A shy burrowing yet curious fish.


An elongate fish with large protruding eyes set high on its head and a surprisingly large mouth. It will sit on the substrate raised slightly on its pelvic fins when it's not in its burrow. It is yellow in colour with small iridescent blue spots.
