Happy gray chub
I watched a small shoal of gray chubs going back and forth in shallow water and was pleased to get a photo of this happy fish. To me, it looks like it might be about to break into a song and dance routine.
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.
