Here's one more little fish. Surge area, sitting under a rock overhang in about 2-3 feet of water. Could it be a Ringed Blenny? I know the picture is bad. I didn't know I had him in the shot until I got home.
And here are a few more "Croaker?" Pictures. Looking closer at these, the brassy horizontal dashy lines on the fish's side, do make it look like the picture of the Reef Croaker.
Just a snorkeler...
