Description

The dusky cardinalfish is a small, semi-transparent reef fish of the family Apogonidae (cardinalfishes) reaching about 9 cm. The red-brown body has large eyes and is dotted with fine dark spots. By day it shelters in shaded crevices, caves and large sponges of coral and rock reefs in the western Atlantic and the Caribbean; at night it emerges to hunt small crustaceans and zooplankton. Like many cardinalfishes it is a mouthbrooder: the male broods the egg ball in his mouth until the young hatch. Because of its hidden, nocturnal lifestyle it draws little notice, but it is a familiar resident of shaded reef cavities.
