I've been using these for Flathead bait, and I always refered to them as rockbass. I did some searching and it doesn't fit the description of a rockbass. I'm thinking either Green sunfish or Warmouth-but no red eyes, so I'm thinking Gren Sunfish? I have been catching them along rocks at a marina where my boat is docked. I know that, for me, they live longer than bluegill and are much more acitve. They have are fatter, have a larger mouth and are not as wide form belly to back as a bluegill. This one might have lost some color because he has been in my bait tank in my garage for about a week.
