Tiny,
Sorry about the confusion. As posts get more responses, they sometimes generate some confusion - especially regarding terminology! There are frequently new posters that refer to bluegill as a pond full of "sunfish", without any more information. I realize that does not apply to your posts, since you have said you have pumpkinseeds.
All of the sunfish species belong to Family Centrarchidae. This includes what most people call "sunfish" from Canada to S. Texas, but also includes all of the black bass (LMB, SMB, spotted), and even crappie!
The experts on the forum may refer to Genus Lepomis, which are sometimes called the "true sunfish". That covers bluegill, pumpkinseeds, red-ear sunfish, green sunfish, and most of the other less common sunfish.
If you call them "pumpkinseeds", or even PS, in your future posts, then everyone will be on the same page as you.
Now, after all of my long-winded typing, do you have any other Lepomis species of sunfish in your pond that came in through your marshes or other water connections? Or do you only have the PS that you introduced?
That information will definitely help people give good advice on your management plans.
