Definitely looks like many of the smaller ones are pure BG. Some of the larger ones do appear to be HBG as well. A couple even look like LES. The one that looks especially like an LES is the one in the lower left near the GSF with the gill flapped flared and the gills showing. The more aqua coloration makes him stick out... Squeeky, could you post a few pics of some of those bigger sunfish, I'd be interested in better quality close ups.
