Many of the more territorial fish will do well as single fish. Many (probably most, really) cichlids, many anabantids, many types of catfish (otos and cories being common exceptions), lots of the ancient fish, etc.
How about a Red Headed Geophagus? I love them and had the other one before that looks just like the Red headed one without the red head and a little less color. I had one at the time and he seemed to do well solo. They are not as aggressive as some of the other Cichlids. Never had any excessive aggression problems with the Geophagus. I love their personalities.
