Identify the mystery fish for extra points

Early Saturday morning, Mike and I took several volunteers on a REEF survey in the Waikīkī MLCD. Most of us finished the survey as quickly as we could since the water was very chilly! I only took a few photos and I captured a picture of a fish I can not identify.

I will give extra points to the person who can identify the fish first!

Large Mound Coral, most likely Porites evermanni.
