Thanks ewest.
I had found a lot of those John Lyons pictures in my searches and they are good, but still no RES gill raker pictures.
The written descriptions help, but they remind me of trying to read about my ailments in a medical book based on my symptoms. Pretty soon I think I have every disease and malady known to mankind.
Like the GSF description in your post:
"Sometimes 3-5 bluish lines radiating backward from underneath the eye"
Those bluish lines along with the big mouth are the first things I key to when looking for GSF characteristics. Yet the description says "sometimes". So "sometimes" means there may be GSF out there without any bluish lines. So not being a fish biologists, I likely would incorrectly ID a GSF that lacked the lines because I would not be looking for the other critical indicators.
And THAT's why I come here to PBF for the ID help. And a lot of good help there is! Thanks everyone!
