Gray Chubs and Hawaiian Flagtails

Gray Chubs and Hawaiian Flagtails in the waters off Hawaii

The surge zone is the area above shallow reefs near shore, where incoming swells churn up the water. It’s home to a variety of fish including chubs and flagtails, the turbulent, bubbling water acting as a screen from predators.

Chubs will venture out a ways during the day, but flagtails only emerge at night to feed on plankton.

Hawaiian flagtails and achilles tangs in shallow surging water
Hawaiian flagtails are night feeders, but by day they congregate in shallow areas with a lot of surge as a protection against predators. This shoal was swooshing back and forth in the company of several achilles tang.

In my attempts to identify what I see in the water, I use John P. Hoover’s book The Ultimate Guide to Hawaiian Reef Fishes, Sea Turtles, Dolphins, Whales, and Seals. His website is hawaiisfishes.com.
