I recently got a 7" male Tiger Oscar for my 90g. He's my second Oscar, and is dwarfed by my 9" female Red Oscar. Tiger, the female Red Oscar, has a habit of moving the decor around. I want to make the tank look natural, without Tiger being able to hurt herself trying to rearrange everything. I'd like some pictures of large Oscar tanks, with big Oscars to get an idea of how to make it look good.
