It grows to about 6 centimetres (2.5 inches) in length. 

It is native to the Indian Ocean and the Pacific Ocean. It prefers shallow tropical bays and reefs. 

It is nocturnal, active mostly at night. During the day, it rests in cavities or caves individually or in small groups.

It feeds on small fish, plankton, and invertebrates, such as worms. 

The Ghost Cardinalfish forms groups, called shoals, of about 5-7 individuals.

It is a mouthbrooding fish. After the female lays eggs, the male puts them in his mouth to prevent other fish from eating them. As the eggs hatch into small fish, called fry, the male continues to protect them in his mouth.
