Can you shoot some pix like the last two, but back the camera off some or tell your camera to focus on the fish? They aren't in focus. A good profile head shot would help too.
From what I can see, if I HAD to guess, it could be Scorpaena brasiliensis, but it might also be Scorpaenodes parvapinnis. My money would be on brasiliensis, but it could be something totally different, so good pix are a must.

Although most scorps can be just about any color based on their habitat, this species is generally mottled shades of reds and browns with white highlights, and are quite handsome fish. S. brasiliensis is probably the most common scorpionfish available to the hobbyist, and certainly one of the easiest to care for. It is very hardy and easily fed, as most specimens accept dead food readily, both from a feeding stick or the water column. Although many scorpionfish are cryptic or simply sit there looking like a rock, this species is quite personable and will soon recognize its keeper, looking for a handout.
As you likely noticed, S. brasiliensis will be a large-ish fish, definitely a good 8"+ in captivity. It would likely eat a 2" hawkfish some day.
