This fish reaches 8.5 centimeters in length. It is bright blue in color; the male has a yellow snout and tail, and the female and juvenile usually lack yellow but have a black spot at the base of the back edge of the dorsal fin.[1]


The fish inhabits reefs and lagoons. Its diet includes algae, tunicates, and copepods. Male and female pair up for breeding, and the male guards and tends the eggs.[1]
