Nocturnal species which occurs inshore (Ref. 75154). Found in deep recesses of caves in the outer reef slope (Ref. 1602). Benthopelagic (Ref. 58302). Exhibits the black gut phenomenon. In nocturnal predators, it appears to serve to conceal bioluminiscent prey in the stomach cavity (Ref. 46685). Swims upside-down on ceilings (Ref. 48635). Solitary or in pairs (Ref 90102).

Zapogon evermanni, Evermann's cardinalfish, is a species of cardinalfish native to tropical reefs in the Indian and Pacific Oceans and the western Atlantic Ocean.

It occurs deep in reef caves, where it swims along the ceilings upside-down. It is found at depths from 3 to 69 m (9.8 to 226.4 ft). This species grows to a standard length of 12 cm (4.7 in).

The specific name honors the American ichthyologist Barton Warren Evermann (1853-1932), of the U.S. Bureau of Fisheries.
