We all know how we feel about dyed fish...but what about something that in some lights can potentially be just as cruel?
I have as much a problem with dog breeds and garden-bred flower morphs as I do with selectively-bred fishes. I guess I'm sort of a hippieTo begin with, how can you say if a certain fish's physiology "isn't really altered" ["these manipulations do not distort the fish's basic body plan"] after selective breeding? A hobbyist who wishes to perpetuate a given morph selects only fish that appear to exhibit the desirable characteristic for further breeding. He does not typically take a microscope and determine whether or not any other minor or not-so-minor detail has been altered, internally or otherwise.
