Mines easy, the European Perch. I fell in love with these guys the first time I set eyes on one when my brother caught one of about 6" from a local farm pond. The blood red fins, the stripes, THAT dorsal fin, crikey, and their huge cavernous mouth. My goal one day is to grow about half a dozen juveniles out in a large coldwater set up.

They are super cool fish!
I always think of them as the coldwater peacock bass ?.
