The head and upper body are a light, but brilliant, yellow color slowly fading to a pearlescent blue hue.

It remains near its relatively small territory, and is typically seen with only the head and upper section of its body protruding from its burrow, although it sometimes can be found hovering nearby.

It is able to arrange material using its mouth, carrying sand, shells, or small rocks from one location to another.

During flight, the fish will swim away from the intruder and in go into their burrow, covering the opening with a large rock.

It is one of the most docile jawfish towards fish of its kind, and can be kept in small groups of 1 individual per 10 gallons.
