I have often heard about how "ugly" common carp are, and an old beat up fish from muddy water isn't very eye appealing, yet here is the states we have "feral" fish that lack the better breeding seen in the UK...bloodlines there seek 3 things faster growth, long life for larger size and appearance ...some of the most beautiful fish are Koi, common carp that have been selectively bred for 1000 years for color, scale patterns and fin shapes.....if someone did that for any fish over time could create something interesting...largemouth bass sometimes have a blue and orange color phase.....
