Just picked up a 90 gallon off of craigslist, which for those playing the home game is 48"x18"x24". A 4ft tank is the widest I can fit in the space I have an a 90g is the most area you can get in the 4ft size, which is why I've been looking so hard for one over the much more common 75g. Anyway, now that I finally have a tank thats 18" deep I can actually get a BIG fish, what would you all do with it? Im strongly considering an Oscar tank or a pair of GT's, but am open to ideas. Only rule is your suggestion must require a large tank, I've been there done that on all the small stuff
