a school of convict tangs on a Hawaiian coral reef
A coral reef in Hawaii has hundreds of fish species. Many of the fish are active during the day. For example, species such as convict tangs and stareye parrotfish swim in schools as they feed on seaweed that grows on the reef. At night, other fish species, such as snowflake moray eels, come out to hunt.
When they are not active, some fish take shelter among the many species of coral on the reef. Other fish hide in the sand and rocks that cover the seafloor.
