The tender of a liveaboard diving boat drifts over the corals in the shallow waters surrounding the islands near Halmahera, Indonesia. Coral structures provide shelter for countless fish such as these Anthias. When the currents are flowing it’s feeding time and the countless individuals swim in to the water column to collect food. Any potential threat or even just a disturbance by a noise will send the fish flocking back to the protection of the corals. When the threat has passed they will swim back out in to the blue again and continue feeding.
