Hi Craig,
is this a Redear sunfish?
I believe this is one because of the Redear but the other one doesn't have the Redear?
Thank you,
Joe Kitchens

Looks like a redear, Joe. The 'red' marking on the gill cover can vary in intensity in individuals and among males and females. Sometimes very noticeable other times nearly undetectable.
