A rainbow of color swirls before your eyes as you dive into the crystal blue Pacific waters. Tropical coral reef fish of all shapes and sizes swim past you. Some school together grazing on algae, some hide in holes waiting for an unsuspecting smaller fish to swim by, some use their long tubular mouths to pluck individual coral polyps. Together, they all comprise the myriad of fish species that live together on the Kaloko-Honokohau coral reef.
