My son caught this tonight at Valley Forge National Park near catfish island.

My guess is a green x pumpkinseed, but the shape and mouth show no pumpkinseed. About 2 months ago I caught a green x seed upstream about 3 miles, but that one was more obvious, the body was taller, the mouth smaller, the pattern more pronounced, and the gill spot pure red. There is a batch of green x seed in these waters, and this fish is about the same size as the other green x seed.
The only thing I see different about this fish from a pure green is a larger than normal gill spot, and a slightly different pattern and coloration.
Here is what a typical green looks like at the same location:
