Way of life

The blue angelfish lives very hidden, especially on scree fields in steep and deep outer reefs at depths of five to 80 meters and always stays close to the bottom and to hiding places. It is also found in shallow coral reefs in the southern Caribbean . He lives mainly in pairs, regionally also in harem groups of one territorial male and three to seven females. Like all angelfish, the blue angelfish is a protogynous hermaphrodite, which means that the fish are initially female when they reach sexual maturity and after some time transform into males. In a harem association, the strongest female changes her sex, if z. B. the male has died. Blue angelfish feed on algae and small invertebrates.
