Shades of blue

This morning while snorkeling, I was fortunate to snap photos of 2 lovely blue fish.  The current was pretty strong, and my mask was fogging up, but I just kept aiming the camera and hoping that something would be in focus.

Both fish are terminal-phase males, which means they represent the brightest colors displayed by these species.

First, the bird wrasse (hinalea iiwi).  This fish was about 8 inches long.

Second, the redlip parrotfish (palukaluka).  This fish was about 20 inches long.
