I can see why you guys are saying the fish in the left photo is a green sunfish, the reason I called it a red ear was the size of the mouth. The mouth just looks too small for a green sunfish.
The fish does appear to have a rounded pectoral fin, characteristic of a green sunfish. It would be nice to be able to see all the fins not back lighted to see if the fins have the light yellowish margin that green sunfish have.
