Those are both Bluegill, top one is a male, bottom one is a female.
These are Perch. (specifically Yellow Perch)
Ah, that makes sense. Are there different types of bluegill, or is that actually the specific type of sunfish they are? I am guessing and hoping, that it is just those and the LMB in the pond (and I know there are a bunch of FHM), but I may run a seine net across it when I get a chance. My buddy has one that is 50 feet wide, and I would be surprised if this old of a pond is more than 5 feet dee at the center.
