Man it is tough telling those fish apart. When they are big, not too much of a problem. SOme look like bluegills and some look like green sunfish. Some also look like the hybrids. They are very easy to catch. Yesterday I caught 9 of the 22 in about 10 minutes. I was going to take them out and I got confused on whether I should. I threw them back but I know I can catch them again if I need to. Maybe I should just catch them and take them out so I know for sure. I know I stocked 600 BG so they will be there.
