I go into the lfs to buy that 12" knifefish today, and in the tank next to it is a stunning oscar. the tag said long-finned florida breed oscar $40. Aside from the fins, its pattern is great! it is just under 4 inches. the pectorial fins arean inch and a half long, it has a high fin usually raised, giant anal and tail fins! luckily, despite the superb form, no one will buy it (I hope) people who like oscars, they will save thereselves $30 by buying a good looking common oscar. it is perfect! it will take me a while to save up for, I will not have to set up a separate tank for it, and it will look great.
