Fry - stickleback minnow?
Stickleback of some kind
dead fish, idk if someone couldve left it here or if its natural?
Schooling with other average minnows, distinctive rosy red color
What IS this? Whatever it is, it looks like it was infected with something. It was swimming right up against the surface of the water.
This might have come from an aquarium - this lake had many small orange fish that looked suspiciously like guppies/swordtails
