Nice fish, Chuck! That looks like a finescale triggerfish (Balistes polylepis). The species occurs throughout the eastern Pacific from San Francisco to Chile and west to the Galapagos Islands and Hawaii at depths to 200 feet. Juvenile finescale triggers are pelagic, found under flotsam, but adults are bottom dwellers frequenting sand or rubble patches near coral or rocky reef habitats, feeding mainly on benthic invertebrates such as shrimp, crabs, sea urchins, mollusks and worms. Like other triggerfishes, it’s a nesting species that lays its eggs in the summer months in nests on the bottom scraped out of sand or rubble substrates and guarded by the females. While finescales are indeed one of the larger triggerfishes, growing to around 30 inches long, your 7-pound fish is about half the IGFA all-tackle record of 16 pounds, 4 ounces, also taken in Hawaiian waters, back in 2013. As for the title of “granddaddy of the triggerfishes,” that would probably be shared among the finescale triggerfish; the titan triggerfish, Balistoides viridescens, which grow to the same size (females guarding nests reportedly have attacked divers); and the stone or blunthead triggerfish, Pseudobalistes naufragium, which is the longest in the triggerfish family (Balistidae), growing to around 40 inches long.
