I personally like Oscars and agree they are one of the corner stones of the hobby. Long fin Oscars are however one of the fugliest fish I have ever seen.
Whilst I can appreciate the beauty of the long flowing fins, on an albino oscar like above, I have heard it described that it looks like an overgrown ugly fancy goldfish.
My LFS has a whole tank of baby long fin red tiger oscars. If I was doing a solo oscar tank, I would get one of them. In a community tank though, those fins will be shredded quite easily and look ugly. Also, when I asked on the oscarfishlover forum the consensus was that long fins, like many other traits, may mean the fish has a genetic predisposition to disease, etc. Personally I prefer the ugly brute look of the normal red tiger oscar. It's also much closer to the wild variant than an albino long-finned oscar (which has 2 separate recessive traits), and thus more robust genetically from an evolutionary standpoint I guess.
