The smaller a fish is, the harder it usually gets to superficially identify it and then one has to start using morophological features that do not vary. Looking at the gill rakers will settle this disagreement of, if it is a BG or RES. At least that is what I would do when trying to put a positive ID on small BG or RES. BG rakers will be "long and thin/slender" whereas RES rakers will be shorter and thicker/stubby".
Since DonJ's fish had a damaged opercule flap it is very difficult if not impossible to put a 100%positive ID on the fish from just a photo. DonJ's fish superficially looks like a BG but George Bush, in a photo, could look like a liberal democrat.
