Was fishing with a friend on the Minnesota river last weekend and he caught, actually more like snagged, this fish. Is it a goldeye or a mooneye? When he casted the rapala it must have landed right on the it's head because he was on right away.

looks like bait to me

I'd say mooneye

Mooneye's dorsal fin begins before the anal fin.
Goldeye's dorsal fin begins at and slightly after the anal fin.

I call them all mooneyes.. is there that much of a difference?

Them things are very aggressive fish.. I have no doubt it took the lure.. I have caught them on plastic worms to big rapalas to daredevils .. and just about everything in between.. is their a live bait they dont hit?

Great catfish bait.

I say goldeye, because the dorsal and anal fins begin at the same place.

Also goldeyes have a bright yellow eye... hard to tell in the pic. Thats some good bait right there!

Or some delicious smoked fish... tasty

I was fishing the Red and I loaned a rod to a young girl whose family was sharing rods. She caught a gold eye and yelled," Hey dad, I caught a cutbait." That was their name for all of them.

Goldeye are fun to catch when they're being ravenous. They have nasty teeth too. Here's one I caught just the other day.
