Yellow tang are the most easily identifiable fish, both in and out of the water. Their bright yellow schools, cruising the shallows, are easily seen from shore. In the water, they stand out, especially when the sun catches them.
I watched this pair as they performed what I assumed was some kind of mating dance. They shimmied up and around, dancing apart and then coming together again with the most delicate and touching moves.
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.
