Hey, Puffer! Glad to know you're diving further south. Redspotted is the only Hawkfish family member in tropical Atlantic/Caribbean waters and it's a very pretty fish. They tend to sit on or slowly tour the tops of whatever is there unless they're frightened into a hidey hole, so you may see more. Lots of them in Cozumel...hint, hint...
I get south at least once or twice a year, but for some odd reason, is usually the time I am trying out some new camera gear, and/or one gets those lovely "guided" dives that are at 2 knots, 10 feet above the bottom.
And I know most of the fish if they live farther north... like this guy:
Did not know all the hamlets, but they are easy to look up:
