posty the warmouth down here is what we call a guvment bream. Government stocked them back in the 50's. They have a bigger mouth than a regular bream but smaller than a goggle eye which is a rock bass according to the arkansas game and fish.

the one in the middle is a chinquapin, red ear, shell cracker, mason bream or what ever depending where you live.
easier to classify them all as bream and eliminate all cornfusion
