Yellowtail Coris

A female yellowtail corisTwo juvenile yellowtail coris
The two fish in the second photo are juvenile yellowtail coris. Over time, they’ll transform into adult colors like the one above. The bright blue spots identify this yellowtail coris as a female.

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.
