MYSTERY FISH FROM HONG KONG

This photo of Sai Kung is courtesy of TripAdvisor

Richard Muirhead sent me the above picture. I think that it is some kind of grouper; the serrated back is reminiscent of this Pacific Goliath grouper. Richard's fish looks more elongated, but that may well be an artifact as a result of the curved front of the tank.

What do you think?

Whatever it is, it has almost certainly been eaten by now, as it was photographed in a restaurant in Sai Kung...
