Hahaha, I adopted a single oscar that I fell for instantly when I saw the pics on craigslist, planned on eventually making him the main man of the 75gal I currently had with tetras and guppies who could easily move to the 45gal he was quarentined in, but then Hubby fell for this little tiny bit of an oscar at a horrid petstore and insisted we rescue him, thus the big tank was absolutely necessiary as we didn't want just the 2 fish, we had to have plecs and such. I said 180gal min untill I saw a 220gal setup and then I decided I would take nothing less. I went without a Christmas gift, used tax refund to get the tank, with the promise that it would also count as my birthday gift later in the year. It was worth it
I found a killer deal on a brand new tank a guy had bought and never had the time to setup, so we went to the other side of the state and picked it up, tank and stand still in the box and all, along with every piece of fish related equipment this guy ever had... which was a LOOOTTTT and the 'extra' exquipment alone was nearly worth the $1500 we paid for the tank, stand, and filters.
Now we have 3 oscars (I adopted one from Fishgeek because I loved him and this way she still gets to keep up with him and see pics of him grow) and although the tank looked ginormous for the first few weeks we had it, it has begun to look smaller and smaller to me, expecially when I look out the window and see the 4500gal pond, but alas I don't see a bigger tank in the future any time soon LOL. My dream is a 500gal+ SA setup in a room of other SA critters, reptiles, amphibians, maybe a bird or mammals of some sort, and of course native plants and such as well... But I'd have to win the lottery first... keep your fingers crossed!
