I think the breeding male northern longear sunfish might give the pumpkinseed a run for it's money, but both species are quite gorgeous! I think the prettiest fish I have ever seen was a wild male tiger trout in breeding colors. I wish I would have taken a picture of him.
You're right a longear is pretty impressive too. I don't know why you guys go all google eyed over the tigers though. I think a male brook trout in spawning colors puts them to shame.
