Way of life
Cave filefish live very hidden in lagoons , rocky and outer reefs at depths of one to 20 meters. They prefer areas rich in corals and stay mainly in rock caves, under sponges and large coral stocks. Adult specimens form pairs, but usually only one is visible foraging for food while the partner hides.
