Not sure what type of fry would be 1" long already. I think that's a bit long for perch from this spring wouldn't it?
Maybe bluegill?
They looked like they had tiger bars on them like perch, but I did not handle them as they were too quick for my minnow dipper.
Maybe last seasons LMB fry?
Several years back I caught some perch on a lake up north that had fry in them that looked possibly similar. I'll try to catch and get pics of the ones I am talking about, but here's the ones from the perch stomach. They almost look like bass?
