Monster of the Deep

There is an aquarium tank with native species in it, on the dock at Gosman's Dock in Montauk. I loved the look of this one so I spent some time trying to get a good photo of it. I didn't quite succeed, because you will notice that it is a bit out of focus. The big problem was finding out what kind of fish it is. I had no luck trying to look it up on the web, but the next day I asked, and a fisherman suggested that it might be a Black Sea Bass. If YOU know the answer, I would love it if you could tell me the answer.
