Mediterranean Damselfish

Also known as Mediterranean Chromis, Damselfish, Black Damselfish

Mediterranean damselfish form dense, shimmering clouds over shallow rocky reefs and Posidonia seagrass meadows, darting into open water to pluck passing zooplankton. While mature adults sport a subtle dark brown or charcoal hue with deeply forked tails, the juveniles glow with vivid, iridescent neon-blue stripes that light up dark crevices. During summer breeding, territorial males meticulously clear flat patches of stone, courting females and aggressively guarding the resulting clutches of eggs against wrasses and other reef scavengers.
