This fish is not a pumpkinseed sunfish. Pumpkins have less well-pronounced stripes, more spots, rounded dorsal and anal fins, a more elongate body and an eyespot on the gill. This looks to me like a severum cichlid (
Heros severum) and will not live the winter in this country. Google the two fish and compare.
