With my oscar, I have a green sev, Geo. "Bahia red", 6 clown loaches, a sailfin pleco, and an ornate bichir. That's in a 150 though.
Btw, I'm actually looking to downgrade from the 150 for a little while (about to graduate from college and the next couple years will probably involve moving around and getting married, so I'd prefer to have more portable tanks.), so if you would be interested in a free albino tiger oscar around 11", he's all yours. I'm about an hour and a half north of Cincy, but I could probably meet somewhere closer.
