Creole wrasse school blue fish cruising in coral reef

This wrasse lives in groups, aggregating on coral reef slopes, down to around 100 m (330 ft) in depth. These groups feed on plankton, including small jellyfish, pelagic tunicates, and invertebrate larvae. The creole wrasse is active by day, and at night it retreats alone to a rocky crevice in the reef to sleep.
