Flowerhorn, some Red Devils, Butti, some Midas, Dovii, some Jags.....the list can go on and on. The best thing is for you to pick a fish that you enjoy and make it a solo fish, and they will be happy to have all that room to themselves

Gold fish, Carps, and Guppy... raise it to get the required growth... ahahaha.... just joking... Of course flowerhorn is the best... your can try freshwater barracuda, but i dont think they still exist.. hahaha 
all of the fish I can think of have already been mentioned. great thread idea tho.
I had an aztek cichlid that had to be house alone, but I think that was just becuase that particular fish was evil!

Well my first choice would have to be a GATF,VATF,BATF, aimara, and mala but its finding a way to get them to me at a cheap price so that I don't have to go far is the problem!
+2 for the Hemibagrus Wyckii "Crystal-Eyed Catfish"
They are very aggressive and very territorial. Some have even been known to attack their owners!
Maximum Length of them is said to be 28".
I knew that they changed the genus, but I couldn't remember what to.
I had one for about a month twenty years ago. It was housed with several other big cats, all close in size or bigger than the wyckii. When I came home to find one of my synodontis (who was about 2/3 the length of the wyckii and stocky) sticking out of the wyckii's mouth I had had enough...
Yes, & the hemibagrus wyckioides "Asian Redtail Catfish" is also very aggressive and territorial. Both the Asian Redtail Catfish and the Crystal-Eyed Catfish should be kept alone (unless of course you want to see the other tankmates get eaten).
Unlike the Crystal-Eyed Catfish though, the Asian Redtail Catfish is said to max out at a whopping 38-50"!!
You might want to include an intended tank size...some fish you can keep alone in a 100 can be housed in a larger aquarium.
