Some pics of our sunfish

what is the big yellow one ? (in the pics) his more green/yellow in person
 
im pretty sure its a redbreasted sunfish. they 3rd pic are females, the first pic im not sure if it is an immature male or a different kind of sunfish. how big and old are they?
in my signature i have the 75 gallon thread and there is a green sunfish and some redbreasted just for comparison.
 
the top pics are all the same two fish....
 
You were correct about the Redbreast part, but I do have Longear's too.
This is from a Maryland DNR Biologist over on NANFA. He knows about the fish found in the Potomac as he test that river.

You have longears and redbreasts. The longears that are introduced into Maryland don't really have the impressive opercular flaps. They do however always have the white margin around the flap. The redbreast typically have the longer opercular flap but have no margin around the black of any pigment. There are also various differences between fin and cheek pigmentation you may notice as well as head-body depth ratio as your fish get older.
