To the OP having a personal preference and personal feelings about what a fish breeder would do doesn't make someone naive. Fish on Fire stated something that a lot of responsible breeders would do, which is far more likely than line breeding for the short body trait. I also agree with ecoli73 I personally don't see the short body trait being expressed to any great degree, which you would see in a line bred fish. So it stands to reason since the Oscar is barely expressing the short body trait and it was in a mass shipment of regular Oscars it's a deformed Oscar not a line bred short body. That's just a far more logical conclusion. Mind you this is coming from someone who likes the short body trait expressed on certain fish.
