A large school of beautiful blue tangs sweep across the reef like a blanket of vibrant blue. These fish are mesmerizing to watch as they move in unison, looking for algae among the coral. This school were so intent on feeding that they were oblivious to the cameraman who followed them to capture this footage. The flesh of the blue tang is very poisonous, which protects them from predators. Tangs come in many colors, ranging from brilliant yellow to a deep purple. A group of blue tangs is always a sight to behold.
