Warmouth are odd sunfish in these parts , some days like Skeet says you ketch a few and then other times you don't see one for months .
One thing I know factually is these here warmouths in my area vary a lot in coloration and mean a bunch .
my wife ketched one that was real big and it had zero markings on it for the most part and very pale .
I ketched one about 75 miles away that was real big and was almost black and had definitive speckling .
then I get one about 30 miles from there that is bronze with tiger with bars all over it like a smallmouth cross .
I even seen a few from one lake here that have a slight purplish hue to them.
I think they have the camo thing going on strong kinda like a chameleon maybe , change coloration as the mood or need comes into the play ?
