Sergeants feeding

Sergeant fish feeding off the Big Island
It’s always fun to see fish active just below the surface of the water. Needlefish live in this area, but schools of sergeants also gather there to feed. The fish with the darker stripes and yellow patch on the upper back is the Indo-Pacific Sergeant. It’s a relatively new to Hawaii having arrived around 1990. The fish with less distinct stripes is the Hawaiian Sergeant, an endemic species. Apparently, the two species have been interbreeding, producing a fish with the coloration of the Hawaiian Sergeant, but with the more pronounced stripes of the Indo-Pacific Sergeant.
