I kind of wondered if the third fish might have had some RES in it. It had different coloration on the body and bright white around the fins and belly rather than yellowish like the other two. I know coloration is not a reliable indicator, but the third fish just seemed to have pattern more like RES. GSF have light orange margins around the ear tab, but I thought this fish was darker. Pics do not show what I'm talking about very well.
