welcome to the site wolf, i had trouble finding true pumpkinseeds in the area, most of what i got my hands on were hybrids. Focus on nearby river access and creeks to have your best chance at em. If you ever make it out to the goldsboro area should be able to catch some nice ones and shellcrackers in the neuse from shore. i caught some in falls and crabtree creek but they didn't have the vibrant color I was looking for.
Be careful adding the fish in the order that you did, you chose the two most aggressive sunfish to start out with and they may get territorial with any new fish you add. hope the redbreast eats for ya!
