Purplemask Angelfish

Centropyge venusta

Also known as Venustus Angelfish, Purple-masked Pygmy Angelfish, Blueback Angelfish

Purplemask angelfish inhabit deep seaward reef slopes and rocky drop-offs, where they frequently swim upside down along the ceilings of dark caves and overhangs. Males maintain small harems consisting of several females within intricate networks of coral rubble and vertical crevices. They feed primarily on encrusting sponges, ascidians, and benthic algae, retreating instantaneously into rock fissures when startled.
