I went fishing for some bluegill. I wanted to find some in the 4-7" range to put in my pond. I think I may have caught some green sunfish too. Then I read that you don't want to put greenies in your pond. I cannot tell the difference in greenies and small bluegill. I always thought that bluegill had the blue dot on their gill and orange bellies. I am confused on exactly what I put in. I tried to search for pics, but the posts were older posts and the pics were gone. I need help so I can get rid of these now before they spawn next year. Anyone have pics of both in the 4-7" range so I can see the differences???
