Mystery Fish+ Bunch of Belly Up

[MattK]

Hit up Cranberry lake today and was very disappointed to see a number of dead fish floating. Saw about a half dozen dead sunnies and crappie and a dead brookie around 12-14 inches (unfortunate that the first brookie I see in that lake was belly up). There weren't any noticeable sores on them. Hope that nothing bad is going through there.

Did my biggest pickerel and biggest crappie so far this year today, but it was generally a slow day.

I did catch something that I have never seen before. Unfortunately I left my phone in the car so I don't have any pictures, but maybe someone more experienced can point me in the right direction. The fish was about 8 inches long. Its color pattern was similar to a largemouth, except that it had a slight reddish color on its pelvic and anal fins. It had a single small dorsal fin that was set further back than you would see on a bass. Its mouth was very, very small, smaller than a crappie or sunfish of similar size. It almost looked like a shiner that got really really big. Its eyes were not red so not a rock bass. Any thoughts?
