The Yellow Clown Goby is a small fish with a big personality.  They are generally visible in a home aquarium, either perched on a favourite coral or swimming lazily in the water column. It is a wonderfully peaceful fish and will brighten up any home reef tank.

Care level

Yellow Clown Gobies are a very easy fish to keep and will accept most pellet and prepared foods.  They do not require any specialized care.

Size & Sex

The Yellow Clown Goby grows no larger than 1.5”, making it a great choice for nano reefs.  It has a stocky body and an oversized head, which gives it a commanding presence for its size.  Male and female Yellow Clown Gobies are visually identical.


The goby family consists of over 2000 species of fish.  The majority are found in marine environments but some are native to brackish or freshwater regions.


In the wild, the Yellow Clown Goby feeds on mesozooplankton.  In a home aquarium they can be fed a combination of copepods, brine shrimp, other meaty foods and pellets.  They are not known to be fussy eaters.

Reef Compatible

The Yellow Clown Goby is generally regarded as being reef safe. However, a breeding pair will sometimes lay their eggs on the underside of SPS corals, which can damage them.


The Yellow Clown Goby is one of the most peaceful fish available and makes a well mannered addition to any community reef tank.

Water conditions

The Yellow Clown Goby does not require special water conditions to survive and thrive. Normal salinity of 1.025 is ideal.


The Yellow Clown Goby is uniformly bright yellow.  Its black eye has a white outline.


Like many fish all Yellow Clown Gobies are born female and can change sex when needed.  If two male fish are paired the smallest one will turn female and if two female fish are paired the larger one will become male.  This means that any two Yellow Clown Gobies can form a pair.  While the pair will spawn in captivity the fry almost never survive to adulthood.  Due to the fact that their spawning can damage SPS corals the benefit of housing a pair in debatable.


This yellow clown goby makes a great choice for our the reef casa pico aquariums because of their small size.
